Twenty four cultures of heterotrophic bacteria were isolated from the water of the Rybinsk Reservoir on a medium containing organic matter. Bacteria belonging to the families Pseudomonadaceae and Achromobacteriaceae were most widely distributed; bacteria of the Mycobacteriaceae family were encountered less often. Predominating species which belonged to the genera Pseudomonas, Caulobacter, Flavobacterium, Mycobacterium, and Corynebacterium were isolated from the central part of the Reservoir. The special composition depended on the season. Bacteria of the Caulobacter genus were isolated mainly by the end of July and in May. Bacteria of the Corynebacterium genus predominated in March. Microflora belonging to the genera Pseudomonas and Flavobacterium was more constant. Bacteria isolated on media with the minimum content of organic matter (0.5 mg C per litre) belonged mainly to the Pseudomonas genus. Morphological, cultural, and physiological properties of the bacteria were studied. The bacteria grew on media containing carbohydrates and alcohols as a source of carbon though organic acids were assimilated to a less extent. The activity of catalase was found in the cultures, with an exception of the genera Caulobacter and Achromobacter.
从雷宾斯克水库含有机物的水体中分离出24种异养细菌培养物。假单胞菌科和无色杆菌科的细菌分布最为广泛；分枝杆菌科的细菌较少见。从水库中部分离出了属于假单胞菌属、柄杆菌属、黄杆菌属、分枝杆菌属和棒状杆菌属的优势菌种。其特殊组成取决于季节。柄杆菌属的细菌主要在7月底和5月分离得到。棒状杆菌属的细菌在3月占优势。假单胞菌属和黄杆菌属的微生物群落更为稳定。在有机物含量最低（每升0.5毫克碳）的培养基上分离出的细菌主要属于假单胞菌属。对这些细菌的形态、培养和生理特性进行了研究。这些细菌能在以碳水化合物和醇类作为碳源的培养基上生长，不过对有机酸的同化程度较低。除柄杆菌属和无色杆菌属外，在培养物中发现了过氧化氢酶活性。
