Soybean curd waste-photosynthetic sludge samples from the Kobe plant and the laboratory apparatus yielded purple nonsulfur bacteria with numbers as many as 3.3×10⁶ and 5.0×10⁷ viable cells per mg of dry sludge, respectively. The phototrophic bacteria constituted 8 to 20% of the aerobic heterotrophic bacterial population in the waste sludge. Phototrophic sulfur bacteria and sulfate-reducing bacteria were also found in numbers of the order of 10⁴ viable cells per mg of dry sludge. The predominant species of purple nonsulfur bacteria recoverd were Rhodopseudomonas sphaeroides and denitrifying Rhodopseudomonas sp. that resembles the former species. Unidentified strains similar to Rhodopseudomonas palustris were frequently isolated as well. The occurrence of the phototrophic bacteria as major constituents of the bacterial flora of photosynthetic sludge was also demonstrated by chemical analysis of photopigments therein.
