<unk>  is a gram positive,  rod shaped, motile bacterium of the genus Clostridium. It has been isolated from feces and soil. Produces oval to subterminal spores.
Industrially interesting for its ability to produce butanol, acetone and/or isopropanol at strictly anaerobic conditions at 37°C using a wide range of substrates including (but not limited to) pentoses, hexoses and starch. Its ability to grow in simple, inexpensive  media, stability in regard to strain degeneration, good adaptability to continuous processes and sustained production of solvents well into the log phase are other advantages of this bacterium.
