| 摘 要： | 采用MPN法分析了贵州阿哈湖和云南洱海春秋两个季节沉积物硫酸盐还原菌含量,结果表明淡水湖泊沉积物硫酸盐还原菌含量低于海洋沉积物;洱海沉积物硫酸盐还原菌含量低于阿哈湖沉积物,秋季沉积物硫酸盐还原菌含量高于春季,且有该类微生物栖息的沉积物深度增加。分析造成硫酸盐还原菌含量发生改变的环境因素可能是沉积物中硫酸根浓度、温度以及有机质的变化。 |

| Abstract: | The concentration of sulfate-reducing bacteria(SRB) in sediments of Aha Lake and Erhai Lake in spring and autumn was analyzed by using MPN technique. Results show that the content of SRB in sediments of fresh lake was lower than that of ocean sediments,and the content of SRB in sediments of Erhai Lake was lower than that of Aha Lake,and the content of SRB in autumn was higher than that in spring.Moreover,the depth of sediments with SRB increased.The environmental factors that cause the change of SRB quantity were probably sulfate concentration,temperature and organic matter. |
| Keywords: | sediment sulfate-reducing bacteria Aha Lake Erhai Lake |
