A novel, obligately anaerobic, alkalithermophilic, chemo-organotrophic bacterium was isolated from the sediment of an alkaline hot spring located on Paoha Island in Mono Lake, California, USA. This rod-shaped bacterium was motile via peritrichous flagella. Isolated strains grew optimally in 5-25 g NaCl l(-1), at pH 9.0-9.5 and at a temperature of 58 degrees C and were fermentative and mainly proteolytic, utilizing peptone, Casamino acids and yeast extract. Optimal growth was seen in the presence of elemental sulfur, polysulfide or thiosulfate with concomitant reduction to hydrogen sulfide. Sulfite was also formed in an equal ratio to sulfide during reduction of thiosulfate. The novel isolate could also reduce Fe(III) and Se(IV) in the presence of organic matter. On the basis of physiological properties, 16S rRNA gene sequence and DNA-DNA hybridization data, strain PAOHA-1(T) (=DSM 14826(T)=UNIQEM 227(T)) belongs to the genus Anaerobranca and represents a novel species, Anaerobranca californiensis sp. nov.
从美国加利福尼亚州莫诺湖泡哈岛上一个碱性温泉的沉积物中分离出一种新型专性厌氧、嗜碱嗜热、化能有机营养细菌。这种杆状细菌通过周生鞭毛运动。分离菌株在5-25 g NaCl l(-1)、pH 9.0-9.5和58℃温度下生长最佳，具有发酵性且主要为蛋白水解性，利用蛋白胨、酪蛋白氨基酸和酵母提取物。在元素硫、多硫化物或硫代硫酸盐存在下并伴随还原为硫化氢时可见最佳生长。在硫代硫酸盐还原过程中，亚硫酸盐与硫化物也以相等比例形成。该新型分离株在有有机物存在时还能还原Fe(III)和Se(IV)。根据生理特性、16S rRNA基因序列和DNA-DNA杂交数据，菌株PAOHA-1(T)（=DSM 14826(T)=UNIQEM 227(T)）属于厌氧布兰卡菌属，代表一个新物种，即加利福尼亚厌氧布兰卡菌（Anaerobranca californiensis sp. nov.）。
