Biological conversion of synthesis gas
The anaerobic, photosynthetic bacterium Rhodospirillum rubrum has been chosen for catalysis of the biological water gas shift reaction. In addition, two other anaerobic, photosynthetic bacteria, Chlorobium thiosulfatophilum and Chloroblum phaeobacteroides, have been evaluated as candidates for H{sub 2}S conversion to elemental sulfur. Growth and H{sub 2}S uptake studies in the presence of basal medium indicated that C. thlosulfatophilum is a much superior organism. C. phaeobacteroldes showed sporatic growth at best, with growth always slower than C. thlosulfatophilum. Also, when C. phaeobacteroides experienced slow growth, no H{sub 2}S consumption was observed. C. thiosulfatophilum always showed superior growth and H{sub 2}S uptake, and thus will be selected as the bacterium for H{sub 2}S conversion to elemental sulfur.
