Characterization of alcohol-assimilating photosynthetic purple non-sulfur bacteria and cloning of molecular chaperones from a purple non-sulfur bacterium

We screened several strains which exhibited significant photoorganotrophic growth on a chemically defined synthetic medium containing alcohols. Samples from sewage, rice fields, or other places were inoculated under anaerobic-light conditions at 30°C. After multiple enrichments, the growth characteristics of three fast growing isolates were investigated. We describe also the cloning of molecular chaperones from a purple non-sulfur bacterium.
