Abstract

A novel clostridia bacterial species ( Clostridium ragsdalei , ATCC BAA-622, “P11”) is provided. P11 is capable of synthesizing, from waste gases, products which are useful as biofuel. In particular, P11 can convert CO to ethanol. Thus, this novel bacterium transforms waste gases (e.g. syngas and refinery wastes) into useful products. P11 also catalyzes the production of acetate.

Claims (5)

1. A biologically pure culture of the microorganism Clostridium ragsdalei having all of the identifying characteristics of American Type Culture Collection No. PTA-7826.

2. A composition for producing ethanol, comprising a source of CO, and an effective amount of the Clostridium ragsdalei of claim 1 .

3. The composition of claim 2 , wherein said source of CO is syngas.

4. An apparatus for the production of ethanol, comprising in combination with a first a vessel provided with a source of CO and an effective amount of Clostridium ragsdalei having all the identifying characteristics of American Type Culture Collection No. PTA-7826; and a controller which controls conditions in said vessel for inducing said Clostridium ragsdalei to convert said CO to ethanol.

5. The apparatus of claim 4 , further comprising a second vessel for producing syngas; and a transport system for transporting said syngas to said first vessel, wherein said syngas serves as said source of CO.
