| Abstract: | A thermophilic acidophilic bacterium was isolated from Owaku-dani hot springs of Izu-Hakone National Park in Japan. This bacterium grows optimally at a temperature of 70°C and a pH of 2~3. The isolate was generally spherical in shape, with a diameter of about 0.8~1.2 μm, being gram-negative and nonmotile. The DNA base composition was 44% guanine plus cytosine. Chromatographic, chemical and infrared spectroscopic analysis of the total cellular lipid showed that the lipid constituents contained mainly ether linkages; long chain fatty acids and derivatives were absent. The data presented suggests that the thermophilic acidophilic isolate may have some relationship to the Sulfolobus. |
