FERMENTATION PROCESS

摘要

A fermentation process of producing a product by fermenting a gaseous substrate using microorganisms, which comprises retaining a microorganism immobilized on a carrier in a reaction vessel, feeding an aqueous solution so that at least part of the surface of the microorganism is moistened and passing the gaseous substrate through the void of the aggregate of the microorganism to thereby directly react the microorganism with the gaseous substrate. Thus, methane, formic acid, or the like can be effectively biosynthesized.
