Method for synthesizing short-chain fatty acid by reducing CO2 through zero-valent nano-iron-mediated microorganisms

Abstract

The invention discloses a method for synthesizing short-chain fatty acid by reducing CO2 through zero-valent nano-iron mediated microorganisms. According to the method, the characteristic that nZVI continuously produces hydrogen when encountering water is organically combined with the capacity that microorganisms convert CO2 to synthesize short-chain fatty acid, so that high-valued and specific conversion of CO2 under mild conditions is realized. According to the method, hydrogen generated in situ by nZVI is used as an electron donor through hydrogen nutrition type bacteria, CO2 is reduced to synthesize short-chain fatty acid while thalli grow, and directional synthesis of high-value chemicals through CO2 is achieved.
