A dissimilatory sulfate-reducing bacterium was isolated which differed in morphology and pigment content from previously described species. The organism was mesophilic, obligately anaerobic, gram-negative, nonsporulating, long, and slender with one polar flagellum. Whole cells fluoresced red at neutral pH when excited with light at 365 nm owing to the presence of a pink pigment. Desulfoviridin was present. Reduced minus oxidized spectra of whole cells showed peaks in the position of a c-type cytochrome characteristic of Desulfovibrio species and peaks at about 629 and 603 nm. CO difference spectra showed the presence of a CO-binding pigment with a peak at 593 nm. Lactate and pyruvate supported growth in the presence of sulfate but not in its absence. Sulfate, sulfite, and thiosulfate served as electron acceptors for growth. Hydrogenase was present. The deoxyribonucleic acid had a buoyant density of 1.722 g/cm(3) and a guanosine plus cystosine molar percentage of total bases calculated by two different methods of 61.2 or 63.2.
分离出了一种异化型硫酸盐还原菌，其形态和色素含量与先前描述的物种不同。该微生物为嗜温菌，专性厌氧，革兰氏阴性，不产芽孢，细长，有一根极生鞭毛。由于存在粉红色色素，在365nm光激发下，完整细胞在中性pH条件下发出红色荧光。存在脱硫绿素。完整细胞的还原态减去氧化态光谱在脱硫弧菌属特征性的c型细胞色素位置出现峰值，并在约629和603nm处出现峰值。一氧化碳差光谱显示存在一种在593nm处有峰值的一氧化碳结合色素。乳酸盐和丙酮酸盐在有硫酸盐存在时支持生长，但在无硫酸盐时则不然。硫酸盐、亚硫酸盐和硫代硫酸盐作为生长的电子受体。存在氢化酶。脱氧核糖核酸的浮力密度为1.722g/cm³，通过两种不同方法计算的鸟嘌呤加胞嘧啶占总碱基的摩尔百分比为61.2或63.2。
