International ClassC12P 005/02Foreign Application Priority Data1986-03-14 JPAbstractThis invention provides a new fermentation method and apparatus for the same for producing a substance by a microbial action from a gaseous substrate, wherein the cells of a microorganism fixed to a carrier are held in a reactor, an aqueous solution is fed to said reactor so as to moisten at least part of the surface of said microbial cells, and said gaseous substrate is forced to pass through the interstices of said microbial cells, thereby causing direct reaction between the microorganism and the gaseous substrate and effecting efficient biosynthesis of methane, formic acid and other substances.Other References
