摘要
中度嗜盐菌株DT-W是从马里亚纳海沟的泥中分离出来的。细胞呈杆状(1.5-2m x 0.5-0.8µm)，细胞外伸出鞭毛。NaCl浓度为0.1-15%(最适为3-5%)，pH为6-9，温度为4-51°C(最适为30-37°C)。16S rDNA分析和DNA-DNA杂交分析结果表明，DT-W与海藻单胞菌、轴藻单胞菌和子午藻单胞菌亲缘关系密切。此外，还分析了DT-W的其他生理特性和细胞色素含量。
Halomonas sp. strain DT-W, a halophile from the 11,000 m-depth of the Mariana Trench
Moderately halophilic strain DT-W was isolated from the mud of the Mariana Trench. Cells of the organism were rod-shaped (1.5-2 m x 0.5-0.8 µm) with some flagella extruding from the cells. Growth occurred in an NaCl concentration of about 0.1-15% (optimal: 3-5%), at pH of 6-9, and at temperatures ranging from 4-51 °C (optimal: 30-37 °C). The results of 16S rDNA analysis and DNA-DNA hybridization analyses showed that DT-W was closely related to Halomonas aquamarina, Halomonas axialensis and Halomonas meridiana. Furthermore, additional physiological properties and the cytochrome contents of DT-W were also analyzed.
