Bacterial Periphyton of the Bratsk Reservoir
RÉSUMÉ
Results of studies of bacterial periphyton carried out in Balagan Bay of the Bratsk reservoir (East Siberia) in 1981, 1987 and 1993 are presented. The density of bacterioperiphyton changed from 0.3 to 0.9 million cells/cm2. The level of microflora development and the morphological composition in periphyton communities are different in various water strata. The thermocline is characterized by the domination of bacillar forms and the most diversity of morphological forms of microorganisms. The direct connection between number of bacteria on overgrown glasses and their morphological diversity had been observed. Tendency to the decreasing quantities of bacteria in the periphyton during 1981−1993 had been observed. This phenomenon is correlated with the water provision of a year.
