摘　　要：文章针对嗜热硫酸盐还原菌在不同温度下的生长及硫代谢进行了研究。研究发现随着生长温度的降低,其指数生长阶段的生长速度在降低,稳定生长阶段的时间在延长。并且随着生长温度的降低,其硫代谢的产物发生变化。随着生长温度的降低,该嗜热硫酸盐还原菌的代谢过程有硫代硫酸盐出现,硫代硫酸盐能够进一步被还原生成硫离子。当生长温度降低到30℃时,只有硫代硫酸盐生成,而没有硫离子出现。The growth and the sulfur metabolisms of themophilic sulfate-reducing bacteria（SRB） were studied in this paper. It was found that the growth rate of the thermophilic SRB decreased during the exponential phase and the time of stable phase increased with the decrease of the growth temperature. With the decrease of the growth temperature, the thiosulfate appeared as an internal reduction product. When the growth temperature decreased to 30 ℃, there were no sulfide was generated.
