采用荧光原位杂交法分析了贵州阿哈湖深层水环境中总微生物、真细菌和硫酸盐还原菌数量.结果表明:该湖水中微生物总量为1.6×107个·L~(-1),真细菌占微生物总量的52.9%,且微生物总量和真细菌数量垂直变化无明显差异.随着水体深度的增加,活性微生物数量增加,且微生物的群落结构更加复杂.阿哈湖深层水体中有一定数量的硫酸盐还原菌存在. |

The study with fluorescence in situ hybridization(FISH)on the total amount of microbes and that of sulfate-reducing bacterium(SRB)in the deep aquatic environment of Aha Lake in Guizhou Province of China showed that the total amount of microbes in the deep aquatic environment was 1.6×107 ind·L~(-1),52.9% of which were eubacteria.No obvious difference was observed in the vertical distribution of the amounts of total microbes and eubacteria,but the quantity of active microbes was larger and the microbial community was more complex with increasing water depth.There existed a definite amount of SRB in the deep aquatic environment. |
