Two strains of new photosynthetic bacteria were isolated from salt meromictic lakes Mogilnoye and Faro. The bacteria are abligate phototrophic anaerobic cultures which utilize H2S as an electron donor by oxidizing it to elementary sulphur and sulphates. Sulphur is liberated outside the cell. The cultures contain bacteriochlorophyll e and carotenoids of the isorenierathene type. Photosynthetic structures are represented by chlorobium-vesicles. According to these properties, the cultures belong to the Chlorobiaceae family. The bacteria have no gas vacuoles. The cells form 10--20 apophyses-prosthecae which is typical of the Prostheocochloris genus. The new strains differ from Prosthecochloris aestuarii by the brown colour of the cell suspension, the composition of pigments, and ecology. They are classed as a new species Prostheocochloris phaeoasteroidea nov. sp. Diagnosis of the new species is presented.
从莫吉尔诺耶湖和法罗盐性半混合湖分离出两株新型光合细菌。这些细菌是专性光合厌氧培养物，它们通过将硫化氢氧化为单质硫和硫酸盐来利用硫化氢作为电子供体。硫在细胞外释放。培养物中含有细菌叶绿素e和异菌绿素型类胡萝卜素。光合结构由绿菌囊泡代表。根据这些特性，这些培养物属于绿菌科。这些细菌没有气泡。细胞形成10 - 20个突出的菌柄，这是原绿球菌属的典型特征。这些新菌株在细胞悬液颜色、色素组成和生态学方面与河口原绿球菌不同。它们被归类为一个新物种——暗黄原绿球菌新种。给出了该新物种的诊断。
