Photoautotrophic bacteria growing under anaerobic conditions in the light at 28 degrees C with carbon dioxide as a sole source of carbon were isolated from the ooze of the Vanda Lake at a depth of 68 m. The cells are rounded gram-negative rods, and form a dark-red pigment. The morphology and physiology of the cells were studied as well as absorption spectra of the cells and isolated pigments. The main maxima of absorption were found to be shifted to a short-wavelength region of the spectrum. This fact and peculiar conditions of their habitat as well as some other characteristics are the reasons why these bacteria are classed as a new species Chomatium vanda. As far as we know, this is the first description of photosynthetic bacteria inhabiting the Vanda Lake in the Antarctic.
在28℃光照条件下，以二氧化碳作为唯一碳源在厌氧环境中生长的光合自养细菌，是从深度为68米的旺达湖软泥中分离出来的。这些细胞是圆形革兰氏阴性杆菌，并形成暗红色色素。对细胞的形态和生理以及细胞和分离色素的吸收光谱进行了研究。发现吸收的主要峰值转移到了光谱的短波长区域。这一事实、它们特殊的栖息地条件以及其他一些特征，就是这些细菌被归类为新物种旺达湖色杆菌的原因。据我们所知，这是对栖息在南极旺达湖中的光合细菌的首次描述。
