Abstract
The number and flora of aerobic heterotropic bacteria were studied for running water, Aufwuchs and river bed sediments of the Sagami River, Kanagawa Prefecture. The numbers of aerobic heterotrophic bacteria were 104-106 cells/ml in water and 106-107 cells/cm2 in Aufwuchs. In the river water, Flavobacterium was the most predominant bacterial genus which accounted for 31.3-43.8% of the total heterotrophic bacteria, and Acinetobacter and Moraxella were followed as the secondarily predominant bacteria. These three genera comprised 50-75% of the total heterotrophic bacteria. More Flavobacterium was found in periphyton than in water.
