title: [Number of butyric acid bacteria belonging to the genus Clostridium in the slimy sediments of Volga reservoirs].
abstract: The number of Clostridium pasteurianum, Cl. butyricum, and Cl. acetobutylicum was determined in ooze deposits of the Volga River reservoirs using enriched nutrient media. The bacterial number for the two former species was about 1 + 10(6) cells per 1 ml of ooze with a high content of easily assimilated organic substances, thus being by 1--3 orders of magnitude higher than for Cl. pasteurianum on media without nitrogen. The bacterial number for Cl. acetobutylicum was 0.1--1 + 10(3) cells per 1 ml.
