Ectothiorhodospira halophila: A new species of the genus Ectothiorhodospira
A halophilic purple sulfur spirillum, previously reported by the authors and called SL-1, has been characterized as a new species of the genus Ectothiorhodospira, E. halophila. The organism can grow in media containing from 9% NaCl to 30% NaCl. It needs no vitamins. Succinate or acetate can be used as hydrogen donors, but a reduced sulfur source is necessary for growth. The temperature optimum is 47°C. The cells are bipolarly flagellated, not monopolarly flagellated as previously reported.
