Abstract

A biologically pure isolate of a selected bacterium derived from Clostridium autoethanogenum is described which has improved efficiency in the production of ethanol by anaerobic fermentation of substrates comprising carbon monoxide. The bacterium can produce ethanol and acetate at an ethanol to acetate ratio of at least 1.0 and has a productivity of at least 1.2 g of ethanol/l of fermentation broth per day. The bacterium is also characterized in that it has substantially no ability to sporulate.

Claims (11)

1. A biologically pure isolate of a selected bacterium derived from Clostridium autoethanogenum , said bacterium having the following characteristics:

(i) substantially unable to sporulate;

(ii) grows in minimal medium in the absence of yeast extract;

(iii) non-motile;

(iv) gram positive;

(v) rod-shaped; and

(vi) produces products comprising ethanol and acetate by anaerobic fermentation of a substrate comprising CO,

wherein the bacterium has an ethanol productivity of at least 1.2 g of ethanol/L of fermentation broth/day.

2. The isolate of claim 1 where the ratio of ethanol to acetate is at least 1.0.

3. The isolate of claim 2 where the ethanol:acetate ratio is at least 1.2.

4. The isolate of claim 2 where the ethanol productivity is at least 2.0 g ethanol/L fermentation broth/day.
