Aspergillus cejpii is used in metabolism of a flammable and explosive gas. It has been determined that Aspergillus cejpii S8 exhibits an excellent absorption and metabolism effect for a flammable and explosive gas such as hydrogen and methane, and a mixed gas including the flammable and explosive gas. The Aspergillus cejpii S8 strain can undergo a metabolic process with a flammable and explosive gas or a mixed gas including the flammable and explosive gas as a carbon source and/or an energy source, thereby achieving the efficient treatment of the flammable and explosive gas or the mixed gas including the same. The Aspergillus cejpii S8 strain demonstrates high environmental safety and a prominent removal effect and can be conveniently used without toxic and side effects, which facilitates the application and transformation.
1 . A method for metabolizing a gas, comprising placing Aspergillus cejpii S8 or a microbial agent comprising Aspergillus cejpii S8 in an atmosphere of the gas, wherein the gas is hydrogen or a mixed gas and the accession number of Aspergillus cejpii S8 is CGMCC NO. 40828;
wherein the mixed gas comprises one or more mixed gases selected from the group consisting of the following:
(1) hydrogen and carbon dioxide;
(2) hydrogen and methane; and
(3) hydrogen, methane, and carbon dioxide.
2 . The method according to claim 1 , wherein the microbial agent is a suspension of Aspergillus cejpii S8.
3 . The method according to claim 1 , wherein in the mixed gas of (1), a volume ratio of the hydrogen to the carbon dioxide is (1-2):(1-2).
4 . The method according to claim 1 , wherein in the mixed gas of (2), a volume ratio of the hydrogen to the methane is (1-2):(1-2).
5 . The method according to claim 1 , wherein in the mixed gas of (3), hydrogen, methane, and carbon dioxide are in a volume ratio of 1:1:1.
