Acidogenic clostridia and processes of using thereof for producing volatile fatty acids

摘要

An isolated biologically pure culture of Clostridium tyrobutyricum ITRI04001 or an isolated biologically pure culture of Clostridium tyrobutyricum having the genotypic characteristics of ITRI04001 useful for syngas fermentation. Volatile free acids are produced by a method comprising culturing a microorganism having the genotypic characteristics of ITRI04001 in a medium; providing at least one substrate comprising at least one carbon source chosen from CO and CO₂ to the microorganism; and recovering at least one free volatile free acid. Syngas can be the at least one substrate in these processes for producing volatile free acids.
