Abstract

Eleven strains of extrem thermophilic bacteria belonging to the Bacillus Stearothermophiles were isolated from the hot springs of Sichuan and Tibet. The cells were gram-positive, sporulating and motile. The optimum temperature for growth was between 65 degrees C to 70 degrees C; the maximum 94 degrees C, and minimum 40 degrees C. The colour of colony was yellow to bright orange. The G+C content of the DNA in strains has been found to be in the range 48.4-53.15 mol%.

摘要

从四川和西藏的温泉中分离出11株属于嗜热脂肪芽孢杆菌的极端嗜热细菌。这些细胞革兰氏阳性,能形成芽孢且具运动性。生长的最适温度在65℃至70℃之间;最高温度为94℃,最低温度为40℃。菌落颜色为黄色至亮橙色。已发现这些菌株中DNA的G+C含量在48.4 - 53.15摩尔%范围内。
