An isolated clostridia bacterial species ( Clostridium coskatii ATCC No. PTA-10522, “PS02”) is provided. Under anaerobic conditions C. coskatii can convert CO and/or H 2 and/or CO 2 to ethanol or acetate. Thus, this bacterium is capable of transforming waste gases (e.g. syngas and refinery wastes) into useful products.
1. An isolated biologically pure culture of the microorganism Clostridium coskatii having the genotypic characteristics of ATCC No. PTA-10522.
2. An isolated biologically pure culture of the microorganism Clostridium coskatii , ATCC No. PTA-10522 having the ability, under anaerobic conditions, to produce ethanol from gaseous substrates selected from the group consisting of carbon monoxide, carbon dioxide and hydrogen or combinations thereof.
3. The isolated biologically pure culture of claim 2 wherein the gaseous substrates are provided by syngas.
4. An isolated biologically pure culture of the microorganism Clostridium coskatii , ATCC No. PTA-10522 having the ability, under anaerobic conditions, to produce acetate from gaseous substrates selected from the group consisting of carbon monoxide, carbon dioxide and hydrogen or combinations thereof.
5. The isolated biologically pure culture of claim 4 wherein the gaseous substrates are provided by syngas.
6. An isolated biologically pure culture of the microorganism Clostridium coskatii , ATCC No. PTA-10522 having the ability to produce ethanol from an anaerobic aqueous nutrient medium comprising sources of carbon.
7. The isolated biologically pure culture of claim 6 where the source of carbon is not an organic complex carbon source.
8. The isolated biologically pure culture of claim 6 where the source of carbon is not yeast extract.
9. An isolated pure culture of the microorganism Clostridium coskatii , ATCC No. PTA-10522 having the ability to biosynthesize acetate from an anaerobic aqueous nutrient medium composed of an organic carbon source.
10. An isolated pure culture of the microorganism Clostridium coskatii having 16S rDNA sequences as set forth in SEQ ID NO. 1, SEQ ID NO. 2, and SEQ ID NO. 3.
