The main products of syngas fermentation include ethanol, butanol, acetic acid, butyric acid, and methane.
However, using corn as a feedstock to produce either ethanol or butanol seems infeasible without significant technology improvements regarding yields.
Butanol, with a four-carbon chain, is moderately soluble because of a balance between the two trends.
Nichitsu also branched out into other products produced from calcium carbide, beginning production of acetic acid, ammonia, explosives and butanol.
Yeasts as production organisms for butanol have decisive advantages compared to bacteria.
Alternatively, butanol may be added to the resolving gel (for proteins) after it is poured, as butanol removes bubbles and makes the surface smooth.
Ethanol and, to a lesser degree, methanol and butanol are the other major types of biofuel.
Butanol has been tried to remove during fermentation by many techniques like adsorption, gas stripping and liquid-liquid extraction.
