Abstract
Vertical distributions of the numbers of total bacteria and aerobic heterotrophic bacteria, and the flora of the latter in the water and sediment of Lake Motosu-ko were studied in summer, late autumn, and early spring. The numbers of total bacteria and aerobic heterotrophic bacteria in the water were in the order of 10^4 and 10^1-10^2 cells per ml, respectively. The number of aerobic heterotrophic bacteria in the sediment was in the order of 10^4-10^5 cells per ml wet sediment. A total of 609 isolates, 459 from the water and 150 from the sediment, were identified to generic level. Most (84.1%) of the isolates from the water were Gram-negative bacteria. The predominant genera were Flavobacterium (53.9%), Pseudomonas (11.3%, and Moraxella (11.3%). The bacterial flora of the water showed remarkable variations according to water depth, season, and rainfall. On the other hand, most (73.9%) of the isolates from the sediment were Gram-positive bacteria, dominated by Bacillus (55.4%). The bacterial flora of the sediment was rather stable throughout the three seasons.
