DETAILED DESCRIPTION

[0030] Carotenoids are long-chain isoprenoid molecules that have nutritional advantages as colorants and additives in fish feed, animal feed and nutraceuticals because they provide protection against cellular oxidative damage, in particular against free radicals and reactive oxygen species. Carotenoids can be expressed in plants, algae, archaea, fungi and bacteria, both naturally and through the expression of one or more carotenoid genes that encode the biosynthetic enzymes. Traditional production of forty-carbon (C40) tetraterpene carotenoids, including carotenes and xanthophylls, has involved extraction of native molecules from various microbes or plants. However, some naturally-occurring producers of astaxanthin, such as the yeast Xanthophyllomyces produce a less valuable enantiomer of astaxanthin and the process of growing highly productive, naturally producing microalgae, such as Haematococcus pluvialis, is difficult, time-consuming, resource-intensive and expensive.

[0031] Non-biological production of molecules such as astaxanthin and canthaxanthin, via chemical synthesis from petroleum feedstocks, has been achieved (Ernst, 2002). However, these latter methods produce a mixture of astaxanthin enantiomers that are also less valuable because they are less efficient radical quenchers and therapeutics and these synthetic products have faced significant regulatory issues with regard to human and animal consumption in the EU. More recently, genetically-engineered organisms have been used for the production of high-value canthaxanthin, astaxanthin and other C40 carotenoids and xanthophylls. Figure 1 shows the carotenoid biosynthesis pathway from farnesyl diphosphate (FPP) to astaxanthin. [0032] In addition to astaxanthin, canthaxanthin is a valuable carotenoid product that can be synthesized by ketolase enzymes, such as the bacterial crtW ketolase gene acting on betacarotene as its substrate. Carotenoids such as canthaxanthin and astaxanthin can be produced by ketolases encoded by crtW genes from various Brevundimonas species, which are considered to be the most active and effective carotenoid ketolases.

[0033] There is also a need for an expression system that can cheaply and efficiently produce carotenoids using this CrtW enzyme, since the yield of carotenoid per gram dry weight of biomass and rate of production is not high in natural or genetically modified organisms.

[0034] Hydrogen-oxidizing bacteria are attractive hosts for carotenoid expression because some species naturally produce larger amounts of internal membranes than many other bacteria, and these membranes are required for accumulating the highly lipophilic C40 carotenoids.

[0035] Extensive membrane capacity is also advantageous because both the CrtZ hydroxylase and the CrtW ketolase enzymes are likely integral membrane proteins that contain transmembrane (TM) helices capable of spanning cell membranes.

[0036] Furthermore, because certain hydrogen-oxidizing bacteria such as Cupriavidus necator do not naturally make carotenoids, there is less of a chance of regulatory interference (e.g., feedback inhibition) or undesirable enzymatic modification of the product (as in, for example, Brevundimonas vesicularis strain DC263, which naturally hydroxylates the astaxanthin product to dihydroxy-astaxanthin because it contains the crtG gene).

[0037] The carotenoids so produced are provided as part of the bacterial biomass or extracted from it to create a substantially pure carotenoid product, or through other extraction methods such as super critical CO2 or solvent based extraction to form a concentrate. Further, carotenoids such as canthaxanthin can be mixed with other ingredients, such as sugars, corn starch, lignosulphonate, binders, oils or others to produce a product (e.g., DSM Carophyll Red 10%).

[0038] The bacterial CrtW enzymes employ 6-8 of the following amino acid residues to bind the di-iron cofactors that catalyze the oxygenation reactions: His69, His73, Hisl07, His 110, Hislll, His225, His228 and His229, as determined by the presence of the His-rich motifs HX(3 or 4)H, HX(2 or 3)HH, and HX(2 or 3)HH . Aspll8 may also be required, based on mutagenesis studies. Thus, although not intending to be bound by any particular theory of operation, it is believed that natural or engineered versions of this enzyme should or must include these ligands in order to have catalytic activity. Likewise, such enzymes may require functional transmembrane sequences since there are putative TM helices that appear to organize the iron binding sites on the inside of the membrane.

[0039] Expressing such codon-optimized gene pathways in bacteria that have high G + C content has previously proved to be challenging, for example, because the GC content makes it difficult to de novo synthesize genes and operons for synthetic biology.

[0040] The present disclosure describes a newly discovered crtW gene from a new strain of Brevundimonas, designated herein as OB307, which encodes a novel ketolase for carotenoid synthesis. The intensely red-colored bacterial strain was isolated from a contaminating colony on a laboratory agar Petri plate. In a microscope, the cells are short rods, approximately 0.5 pm x 2.0 pm in length. This non-pathogenic, aerobic bacterium can be cultivated in a variety of different heterotrophic culture media, including Luria-Bertani broth and agar medium and MR2 minimal medium with 2% (w/v) fructose. Suitable growth conditions include shaking in a glass culture flask with a Bellco cap at 150 rpm at 30°C. This specific crtW gene can be utilized for the production of useful and valuable carotenoids such as asthaxanthin and canthaxanthin from beta-carotene.

[0041] The present disclosure also provides an exemplary synthetic operon containing additional relevant carotenoid gene sequences, the expression of which is used to produce ketocarotenoids. Suitable DNA expression constructs derived from these sequences are inserted into an expression host for expression. The expression product being a ketolase enzyme that is operable for transforming beta-carotene into canthaxanthin and astaxanthin. The carotenoid products of this synthetic operon have been expressed in Escherichia coli, Bacillus subtilis B-14200, Bacillus B-356, Rhodopseudomonas palustris, Rhodobacter sphaeroides and Cuprividus necator. R. palustris and R. sphaeroides are commonly known as purple non-sulfur (PNS) bacteria. Rhodobacter capsulatus is another PNS bacterium that can be used as a host for these DNA expression constructs.

[0042] As disclosed herein, the presently disclosed CrtW ketolase enzyme is often utilized for production of ketocarotenoids such as astaxanthin and canthaxanthin via cloning of the disclosed DNA sequences (including similar sequences having attributes noted herein), arranging the DNA into a construct that includes a ribosome binding site, a promoter, and a terminator, as well as other structural gene elements. Other enzyme genes according to the present embodiments, such as crtZ, crtY, crtl, crtB, crtE, as well as additional structural and control elements are also optionally incorporated into the construct to form an operon for carotenoid production. This construct is then introduced into a host organism such as a host cell, using methods known to the art, either as one or more small, circularized DNA vectors, such as a plasmid, or via incorporation into the genome of the organism. For organisms that already produce beta-carotene, the gene encoding this single enzyme is introduced to cause the production of this CrtW ketolase enzyme and the transformation of some of the betacarotene into canthaxanthin. If a crtZ gene is also introduced, the gene product (i.e., a hydroxylase) may also be expressed, and it will transform at least some of the canthaxanthin to astaxanthin.

[0043] The product of this crtW gene is used, for example, in a cell free expression system in which beta-carotene is enzymatically converted into canthaxanthin. If the crtZ and crtW genes are expressed in combination, either simultaneously or sequentially, at least a portion of the beta-carotene substrate will be transformed into canthaxanthin and a portion is transformed into astaxanthin by the action of the enzyme products of the two genes. The novel crtW and crtZ genes may be provided on two different segments of DNA, or as a single piece of DNA comprising a gene for a fusion protein, which encodes both the CrtW ketolase and CrtZ hydroxylase functions.

[0044] Many different organisms are potential heterologous expression hosts for this novel crtW gene. Hosts that care able to utilize H ₂ and CO ₂ as energy and carbon sources and those that are unable to utilize H ₂ and CO ₂ as energy and carbon sources are contemplated as suitable heterologous expression hosts. For example, these include bacteria, plants, algae, archaea, and fungi. Bacteria such as Escherichia coli and Bacillus subtilis, fungi such Saccharomyces cerevisiae and Aspergillus oryzae, plants such as Oryza glaberrima, algae such as Chlorella vulgaris, or archaea such as Sulfolobus solfataricus, or others species of organism can serve as heterologous expression hosts for this novel crtW gene, for the production the enzyme which it encodes and for the production of the carotenoid products through the action of this enzyme.

[0045] The heterologous expression of this enzyme and the synthetic operon disclosed herein have been shown in Escherichia coli, Bacillus subtilis B-14200, Bacillus B-356, Rhodopseudomonas palustris, Rhodobacter sphaeroides and Cuprividus necator initially using a broad host range expression plasmid. In all cases, the heterologous expression of the novel OB307-crtW gene was observed via production of canthaxanthin in the transformed bacteria (versus no production of canthaxanthin in the wild type organism). This transformation was achieved using the same plasmid as was used in C. necator. The promoter disclosed herein is active in all of these strains. The E. coli cells were transformed using electroporation of the plasmid, as described above. The other strains were transformed using conjugation with E. coli strain S17-1 according to standard methods (see, e.g, Phornphisutthimas et al., 2007; Gruber et al., 2015). The conjugated cells were first plated on LB agar, then resuspended in sterile liquid medium with serial dilutions and plated on the following agar plates: (1) for E. coli, LB plus 50 pg/ml kanamycin or 10 pg/ml tetracycline; (2) for Bacillus, MR2 medium plus 2% fructose and 50 pg/ml kanamycin; and (3) for C. necator and the PNS bacteria, MR2 medium plus 2% fructose and 500 pg/ml kanamycin. Surviving transconjugant colonies were then picked and restreaked on fresh plates until pure single colonies were obtained. Growth in liquid cultures was performed by inoculating cells of a given variant into LB plus antibiotic (for all of the strains) or MR2 plus antibiotic (for the H2-oxidizing PNS bacteria and C. necator).

[0046] A fusion gene which comprised of crtZ and crtW was created by constructing a piece of synthetic DNA in which crtZ and crtW were joined by a linker sequence, and incorporating this fusion sequence into the synthetic operon in place of the original crtW gene in the expression plasmid. This heterologous expression vector was then transformed into Escherichia coli and Cupriavidus necator. Production of astaxanthin and canthaxanthin was observed in both cases. An allelic exchange system (using NaCI-free agar medium with 6% sucrose (w/v) for the sacB levansucrase counterselection) and suicide vector were also used to insert this synthetic operon into the C. necator genome and the production of carotenoids was again observed.

[0047] C. necator strain H16 has been used as an expression host, as have other C. necator strains, and strains of other hydrogen-oxidizing bacteria. The carotenoid products can thus be produced by gas fermentation of the transformed bacterium, using inexpensive feedstocks (e.g., waste CO2, H2, O2 and mineral salts) to improve the economic efficiency of the process. [0048] Additional genera and species of hydrogen-oxidizing bacteria that can be transformed with the vectors and DNA constructs described herein for heterologous expression in the carotenoid pathway while growing on H2-CO2-O2 include, for example, Rhodobacter capsulatus and other Rhodobacter species, Paracoccus, Rhodococcus, Hydrogenophaga, Rhodospirillum, Rhodopseudomonas, and the like.

[0049] The novel strain of Brevundimonas OB307 was isolated as a red-orange contaminant colony from an agar plate in the laboratory. Its 16S rRNA genes were sequenced (forward and reverse), and compared using Clustal W to the 16S sequences of other Brevundimonas species. This analysis revealed that OB307 has a 99.7-99.8% identity with the 16S sequences from B. vesicularis and B. nasdae. Genomic DNA was extracted from approximately 100 mg of wet cell paste, the entire genome was sequenced using 60x Illumina paired end sequencing (150 base pair reads), and the sequence contigs were assembled and annotated by SNPsaurus, Inc. (Eugene, OR). From this sequence, a BLAST search identified multiple genes with high similarity to other published carotenoid biosynthetic genes.

[0050] One of the complete open reading frame sequences was initially identified by the annotating software as a "fatty acid desaturase." Fatty acid desaturases are known to have a similar structure to carotenoid ketolases, and further analysis revealed that this sequence has high similarity to CrtW-type carotenoid ketolases, and our subsequent expression cloning confirmed its activity. The gene sequence is therefore designated herein as QB307-crtW (SEQ ID NO: 1). As can be seen from the translated amino acid sequence of OB307-CrtW, it contains the eight-histidine motif (highlighted in yellow) and the Asp-118 (highlighted in blue) that define the di-iron binding site for this type of ketolase (SEQ ID NO: 2). SEQ ID NO: 3 shows a Clustal W 2.1 amino acid sequence alignment between OB307-CrtW and the CrtW from Brevundimonas strain DC263 (GenBank accession number ABC50116.1). Both proteins contain 241 amino acids, and there are 11 amino acid differences between them (about 95.5% identity). More recently, a putative crtW gene from Brevundimonas strain SgAir0440 was published as part of the genome sequence of an air-contaminating bacterium (GenBank accession number QCR00114). The gene has 99.6% similarity to the amino acid sequence of OB307-crtW, however, it was not reported to have been cloned and expressed, nor was the function of the enzyme analyzed to confirm that it was indeed a beta-carotene ketolase.

[0051] The native QB307-crtW sequence was converted into a new sequence that is codon optimized for expression in C. necator. This new sequence was included as part of a codon- optimized synthetic operon comprising crtE, crtY, crtl, crtB, and crtW, which makes canthaxanthin (Figure 3). Constructs designed to make astaxanthin also included the complete crtZ sequence (Figure 2). The other gene sequences in the pathway were sourced from various other bacteria, with the GenBank accession numbers as follows: the genes crtE, crtY, crtl, and crtB were synthesized from the sequence of the Pantoea agglomerans/Erwinia herbicola pAC- BETA plasmid, M8720/M99707; crtZ was synthesized from the sequence of Pantoea ananatis Strain AJ13355, NC_017533; and crtW was synthesized from the sequence of QB307-crtW described herein. [0052] Synthesis of the operon benefits from a specialized procedure (e.g., as available from Aster Bioscience, Inc.; Livermore, CA) due to the very high G + C content (ca. 61%-70%). A constitutive promoter that is highly active in C. necator was placed upstream of the carotenoid genes to direct mRNA synthesis in the cell. Other suitable promoters are well known in the art and contemplated herein. Inducible promoters, which can be used to control the timing of the onset of gene transcription by applying an external inducer molecule (e.g., IPTG for the lac or tac promoters) or an environmental stimulus (e.g., nitrogen deprivation for the phaCl promoter) can also be used, if they are compatible with the metabolism and transport system of the host. Ribosome binding sites (RBSs) optimized for C. necator were placed upstream of each gene sequence. Spacer sequences were added between the promoter and the RBS of the crtE gene, as well as between the RBS and the start codon of each individual gene, in order to optimize the overall expression. A termination sequence (E.coli rrnB) was placed at the end of the operon to prevent unwanted translation of any downstream elements.

[0053] The synthetic operons (SEQ. ID NO: 6, 7 and 8) were first tested for activity by cloning them into the broad host range plasmid pBBRlMCS-2 (e.g., kanamycin as a selection), using Nde\ and Asel as the flanking restriction sites. The ligated DNA products were transformed into E. coll by electroporation using a Bio-Rad GenePulser II with a Capacitance Extender Plus Pulse Controller II unit (Bio-Rad Inc., Hercules, CA). E. coll cells were made electrocompetent using three washes with cold 10% glycerol according to the methods described in the online protocol of Belcher and Knight (https://openwetware.Org/wiki/Belcher/Knight:_Electrocompete nt_Cells). 50 pl of electrocompetent cells were added to a chilled 1 mm gap sterile cuvette and mixed with 1 pl of DNA (approximately 1-50 ng). The electroporator settings were as follows: 1.2 kV, 25 pF, 200Q. The time constant was typically 3-5 msec. After pulsing, the cells were then transferred to pre-warmed SOB medium in a small sterile tube and allowed to recover at 37°C for 1 hour with shaking. Aliquots were then plated on LB agar with 50 pg/ml kanamycin for antibiotic selection. After incubation at 30°C, colonies were picked and individually grown up in LB broth. Plasmid DNA was isolated from the various clones by standard methods. The DNA was cut with the appropriate restriction enzymes and analyzed by agarose gel electrophoresis to identify the positive clones. Plasmid DNA from one correct clone was transformed into E. coll conjugation strain S17-1. The process described above was then repeated to find correct S17-1 clones. An S17-1 clone containing the synthetic canthaxanthin or astaxanthin operon in the plasmid pBBRlMCS-2 was then conjugated into the C. necator host strain or other host strains by standard methods as described above. After plating on solid MR2-fructose medium (Table 1) containing 500 pg /ml kanamycin, C. necator colonies appeared. Colonies that displayed a deep orange or red color were picked and re-streaked on kanamycin plates to confirm their colored phenotype and antibiotic resistance. Selected clones were picked and grown up in liquid medium with antibiotic.

TABLE 1. Composition of MR2 medium

[0054] As described above, the processivity of the enzymes at the end of the pathway for the production of astaxanthin can be improved by genetically fusing the genes for crtZ and crtW to encode for a chimeric protein. The fusion protein sequence was created by inserting the DNA sequence for a short linker peptide (encoding amino acid sequence GGGGSGGPGS) between the 3' end of the complete crtZ gene from Pantoea ananatis and the 5' end of QB307-crtW gene (without the N-terminal methionine), as shown in the map of Figure 4, as well as SEQ ID NO: 4, SEQ ID NO: 5 and SEQ ID NO: 8. The crtZ-crtW fusion sequence was codon optimized, synthesized, and used to replace the crtW gene in the original operon construct to create the insert known as System 3 (SEQ ID NO: 8). When the expression plasmid encoding this sequence was transformed into a suitable host as described above, the cells expressed astaxanthin (Figure 9 and Figure 10).

[0055] In certain embodiments the pathways contemplated herein are improved by genetic modification, in particular by methods of directed evolution, for example via random mutagenesis and library screening to identify improved variants. Strain engineering of the host genome can also be used to improve expression of the recombinant pathway genes.

[0056] In certain embodiments the operon is inserted into the genome semi-randomly and then screened for production levels. In the case of carotenoid production, this screening can be done by looking for intense color production in colonies from plated libraries of transformants. Accordingly, a custom suicide vector was constructed (based on the non-replicating, allelic exchange plasmid of Hmelo et al. (2015)) so that the operon could be inserted between the mosaic ends (inverted 19-bp inside and outside end sequences) of the phage Tn5 transposon by restriction cloning with Nde\ and Nsi\. A Tn5 transposase sequence was also inserted into the plasmid (using Gateway cloning), along with a tetracycline resistance cassette to act as an antibiotic marker (see, e.g., Figure 5, Figure 6 and SEQ ID NO: 9). The transposon suicide vector was assembled, transformed into E. coll strain S17-1, and then conjugated into C. necator strain H16 as described above. Transconjugants were plated on MR2 agar plus 2% fructose and 10 pg/ml tetracycline as described above, followed by a second plating on LB agar plus 50 pg/ml kanamycin or MR2 agar plus 2% fructose and 50 pg/ml kanamycin to remove the E. coli donor. Orange and red colored colonies were picked for further characterization of their carotenoids as described above. A variety of pale and intensely colored colonies are observed, indicating that the operon has been inserted into a different genome location in each of the clones that expresses carotenoid.

[0057] To rapidly confirm initial expression of the pathway and production of the carotenoid products, C. necator clones with the pBBRMCS-2 expression plasmid were inoculated into 50 ml of sterile liquid minimal medium (MR2 at pH 6.8) at 30°C in shake flasks with 20 g/L fructose added as a carbon source. After approximately 48 hours of growth, the cultures achieved an A620 (optical density measured at 620 nm) of approximately 1.4, and they exhibited a deep orange or red color due to production of carotenoids. Other expression hosts transformed with the expression plasmid, such as Bacillus subtilis strain NRRL B- 14200, Bacillus subtilis strain NRRL B-354, Rhodopseudomonas palustris strain NRRL B4276, and Rhodobacter sphaeroides strain NRRL B1727, have also been cultivated in this way. NRRL strains were obtained from the USDA-ARS Culture Collection (Peoria, IL).

[0058] To evaluate production of carotenoid on gas, cells containing the genomically integrated operon were inoculated into 200-500 ml of sterilized MR2 minimal medium at pH 6.8 (with no carbon source) in a capped, stirred flask (magnetic stir bars) equipped with submerged gas inlets and an exit port. The sterilized external gas inlets, outlets and rubber tubing were capped with sterile disk filters (0.2 pm pore size; cellulose acetate syringe filter, VWR) to prevent contamination from the outside atmosphere. A mixture of H2:CO2:O2 with an approximate ratio of 80:10:10 was supplied by commercial gas cylinders (Praxair, Inc.), or by electrolytic hydrogen from a generator (Parker Dominick Hunter Model 40H; Charlotte, NC). In some embodiments, the CO2 (often containing other gases, such as H2, CO, SO _X , NO _X ) was collected as waste CO2 from cement manufacturing, fossil fuel combustion, petrochemical hydrocracking operations and the like, and was supplied in pressurized cylinders. The gas mixing and gas flow rates were controlled by small network of gas flow meters and mass flow controllers (Alicat Scientific, Inc., Tucson, AZ). The stir plates and flasks were housed in incubators maintained at 30°C. The exit gas was collected and vented to the outside air. Cultures were grown for 72 hours until the cells reached an A620 of approximately 0.4 and turned noticeably red or orange in color. At commercial scale, this type of cultivation is performed in loop bioreactors specially designed for high-volume cultures grown entirely on gas. An example of a loop bioreactor for gas fermentation of methanotrophs (using methane and oxygen as feedstocks) is provided in Petersen et al. (2017, 2020). In another embodiment, the fermentation and cultivation of the host cells expressing the carotenoid genes employs a consortium (i.e., a mixture of different species) so as to improve the growth rate of the carotenoid-containing biomass or improve the overall characteristics of the biomass.

[0059] Production using cell-free systems. It is contemplated that the enzymes and constructs provided in the present disclosure are used to express the pathway enzymes and generate the carotenoid products using cell-free expression systems (Schneider et al., 2010; Gregorio et al., 2019; Khambati et al., 2019). Such a system can, for example, be fed with the simple precursors of the carotenoid pathway, such as IPP and DMAP and FPP, and convert these compounds into the more valuable ketocarotenoid products. Cell free expression refers to an agent that, when combined with a polynucleotide, permits in vitro translation of the polypeptide or protein encoded by the polynucleotide. These systems are known in the art and exist for both eukaryotic and prokaryotic applications. Exemplary cell free expression systems that can be used in connection with the present disclosure include, for example, commercial kits for various species such as extracts available from Invitrogen Ambion, Qiagen and Roche Molecular Diagnostics, cellular extracts made from hydrogen oxidizing bacteria, including a strain selected from Cupriavidus, Rhodobacter, Rhodococcus, Rhodopseudomas, Rhodospirillium, Paracoccus or Hydrogenophaga, in addition to E. coll and other strains.

[0060] Cells were harvested by centrifugation at 6,000 x g for 10 minutes. After resuspending in phosphate buffered saline, the cells were centrifuged again. An aliquot of the washed cell pellet was extracted with n-hexane/methanol (1:1 v/v) in a 1.5 ml microcentrifuge tube. The solvent extract was separated from the cell debris by centrifugation at 14,000 x g for 5 minutes. Carotenoids can also be efficiently isolated and purified from biomass using supercritical CO2 extraction (Valderrama et al., 2003; Di Sanzo et al., 2018).

[0061] Carotenoid analysis. For identifying and assaying the production of carotenoids, 50 pl of solvent-extracted sample was loaded via syringe onto a Symmetry C18 5 pm (4.6 x 250 mm) HPLC (high-performance liquid chromatography) column, which was pre-equilibrated with a solution containing methanol/water 90:10 (v/v). The running solution was composed of a gradient of water, ethyl acetate, and water. The HPLC instrument was a Beckman System Gold equipped with a 168NM diode array detector. The running conditions were as follows: Flow rate: 1 mL/min; Temperature: 30°C. Peaks were identified by comparing their retention times with solutions of known carotenoid standards dissolved in n-hexane. Canthaxanthin standard was obtained from Honeywell Research, Inc.; astaxanthin was from Abeam (Cambridge, MA). Eluted components can also be identified, where possible, by their characteristic absorbance spectra. Sample chromatograms of canthaxanthin (Figure 7) and astaxanthin (Figure 9), as well as their corresponding UV-Vis absorption spectra (Figures 8 and 10), produced using the expression system of the present disclosure are shown. These experiments confirm that the OB307-crtW gene does encode a beta-carotene ketolase, and that the constructs expressing the new OB307-crtW gene do indeed produce canthaxanthin and astaxanthin.

[0062] This crtW sequence sometimes requires codon optimization when the gene is heterologously expressed in various expression hosts, in order to produce sufficient amounts of active enzyme to catalyze the transformation of beta-carotene to canthaxanthin. This is also true for the synthetic operon and for constructs where the gene sequences are arranged to produce fusion proteins, such as crtZ-crt\N fusion proteins. In some embodiments of the present disclosure, the expression host is a plant. In some embodiments the expression host is a fungus, such as Saccharomyces cerevisiae. In some embodiments, the expression host is an alga, such as Chlorella vulgaris. In some embodiments, the expression host is a bacterium, such as a methylotroph (e.g., Methylobacterium extorguens), a methanotroph, (e.g., Methylococcus capsulatus), an acetogen (e.g., Clostridium autoethanogenum), a hydrogen-oxidizing bacterium (e.g., Cupriavidus necator), or a purple non-sulfur bacterium, such as Rhodospirillum rubrum, Rhodobacter sphearoides, Rhodobacter capsulatus, or Rhodopseudomonas palustris. Other potentially suitable bacterial hosts include Rhodococcus opacus, a Paracoccus species, such as Paracoccus zeaxanthinifaciens, or Escherichia coli.
