Abstract
At least one isolated microorganism and a fermentation method to convert hydrogen gas, carbon dioxide gas, and/or carbon monoxide gas to a lower alkyl alcohol and/or carboxylic acid and to produce at least 2% by volume of the lower alkyl alcohol or carboxylic acid in an aqueous-based medium.

A process to develop a butanol-tolerant microorganism comprising a step in which a culture of microorganisms is grown in a fermentation broth comprising at least 4% butanol by volume.
A process to produce butanol comprising steps:
- culturing a butanol-tolerant microorganism in a fermentation broth;
- wherein the microorganism converts a substrate to the butanol;
- and wherein concentration of butanol in the fermentation broth reaches at least 4% by volume
A composition comprising a butanol-tolerant bacterium, wherein said butanol-tolerant bacterium tolerates at least 4% butanol by volume, grows under anaerobic conditions producing butanol, appears as gram-stain positive non-motile cocci, and comprises 16-S rRNA that is at least 97% identical to a strain of Enterococcus.
