Title:
FUNGUS AND BIOLOGICAL AGENT FOR CONTROLLING MERCURY POLLUTION, AND USE THEREOF, METHOD FOR REMOVING MERCURY, AND METHOD FOR IDENTIFYING FUNGUS HAVING ABILITY TO CONTROL MERCURY POLLUTION
Document Type and Number:
WIPO Patent Application WO/2023/092654
Kind Code:
A1
Abstract:
Provided are a fungus and a biological agent for controlling mercury pollution, and the use thereof, a method for removing mercury, and a method for identifying a fungus having the ability to control mercury pollution, which relate to the technical field of the biological removal of mercury. Provided are a Metarhizium fungus and eight non-Metarhizium fungi, and a method for identifying a fungi having the ability to control mercury pollution, and also provided is an enzyme responsible for removing methyl mercury and divalent mercury, which provides a genetic basis for the control of mercury pollution using recombinant bacteria. When the provided fungus or biological agent is applied to a water body, methyl mercury and divalent mercury in the water body can be removed by means of methods such as cultivation and filtration. When the provided fungus or biological agent is applied to the soil, a plant capable of forming a symbiotic relationship with Metarhizium is planted in the polluted soil, and after inoculation with Metarhizium, Metarhizium can grow at the rhizosphere of the plant using the nutrient substance secreted by the rhizosphere to remove methyl mercury and divalent mercury from the soil and reduce the accumulation of methyl mercury and divalent mercury in the plant, thereby achieving the effect of controlling mercury pollution.
