Document Type and Number:
WIPO Patent Application WO/2024/037192
Kind Code:
A1
Abstract:
Provided a strain of Rhodotorula capable of efficiently degrading ethyl carbamate and use thereof. The present invention pertains to the technical field of food biology. Provided is a Rhodotorula strain DL-XSY01, which is capable of efficiently degrading ethyl carbamate (EC) and is deposited under CGMCC No. 23534. The Rhodotorula strain DL-XSY01 is subjected to screening, identification, activation, fermentation, and embedding, and an EC degradation preparation is obtained. The obtained strain DL-XSY01 is subjected to embedding and then prepared into a degradation agent, which can be used for removing EC from fermented food. Furthermore, the degradation agent of the strain DL-XSY01 is used for removing EC from different food systems. The strain has the characteristics of significant EC removal effect, low production costs, ease of use, ease of removal from food systems, and the like, and is widely suitable for fermented food such as alcoholic beverages, fermented dairy products, soy sauce and vinegar.
