The vertical distributions of sulfate reducing bacteria (SRB) in sediments of lakes in Korea (Lake Sihwa and Lake Soyang) and China (Lake Aha and Lake Erhai) were investigated by fluorescence in situ hybridization (FISH). SRB from sediment of Lakes of China were located to deeper layer than those in Lakes of Korea. SRB were not detected below 19 cm and 10 cm depth in sediments of Lake Sihwa and Lake Soyang, respectively. SRB numbers were, however, detected at all observed sediments in Lake Aha and Lake Erhai. In case of lakes in Korea, the proportion of SRB ranged from 2.9 to 25.6% (Lake Sihwa) and ranged from 0.6 to 7.1% (Lake Soyang). For lakes in China, the proportions of SRB were from 0.6 to 19.4% and from 2.9 to 11.2% within sediments from Lake Aha and from Lake Erhai, respectively. The high peaks of SRB numbers in sediments of all lakes were appearing at depths between 0 cm and 2 cm.
