Chloroflexus and cyanobacterial mats developing at 50-65℃ in Nakanoyu and Nakabusa hot springs, Japan, were collected and cultivated phototrophically at 50 and 37℃. Chloroflexus organisms grew when incubated at 50℃, whereas the incubation at 37℃ resulted in the enrichment of pink- to brown-colored cultures, from which different species of phototrophic purple nonsulfur (PPNS) bacteria were isolated. The majority of the isolates grew at temperatures of up to 45℃ and optimally at around 40℃. The high frequencies of the occurrence of PPNS bacteria in hot spring microbial mats suggest that these environments offer a favorable ecological niche for these bacteria.
