| [seasonal changes in the structure of the anoxygenic photosynthetic bacterial community in lake shunet, khakassia]. | seasonal studies of the anoxygenic phototrophic bacterial community of the water column of the saline eutrophic meromictic lake shunet (khakassia) were performed in 2002 (june) and 2003 (february-march and august). from the redox zone down, the lake water was of dark green color. green sulfur bacteria predominated in every season. the maximum number of green sulfur bacteria was 10(7) cells/ml in summer and 10(6) cells/ml in winter. a multi-syringe stratification sampler was applied for the study ... | 2007 | 17633417 |
