The mucilage of cyanobacteria represents a unique habitat for both water column and sediment bacteria. In Lake Vallentunasjön, Sweden, the pelagic Microcystis‐associated bacteria constituted 19–40% of the total bacterial abundance, and their contribution to the total bacterial production was 7–30%. In the sediment, the mucilage bacteria constituted only 1–5% of the total bacterial abundance, but contributed with 8–13% to the total bacterial production during the summer. Microcystis‐associated bacteria thus were less active (bacterial production/cell) than ambient water column bacteria, while in the sediments the Microcystis colonies were ‘hot spots’ with enhanced bacterial activity as compared to other sediment bacteria.

“…Although the Pseudomonas and Flavobacterium have been isolated frequently from the water of various types of lakes, the coryneforms belonging to gram-positive bacteria were rarely obtained from eutrophic lake water (Rheinheimer, 1971;Lighthart, 1975;Tanaka et al, 1977; Konda and Tezuka, 1979;Konda, 1982;Tezuka et al, 1982;Konda, 1985). Especially, the Arthrobacter is predominantly indigenous bacteria in terrestrial soil (Keddie and Jones, 1981).…”

“…In natural waters, detritus and dead phytoplankton were attached with numerous bacteria as compared with living phytoplankton (Jones, 1976;Fukami et al, 1981). Therefore, the relative abundance of freeliving and particle-attached bacteria seems to be regulated by the amount of suitable suspended particles for bacterial microhabitat (Konda, 1984(Konda, , 1985Kato, 1985).…”

Bacterial numbers and floras in the water and sediment of subtropical Lakes Phewa, Begnas, and Rupa in the Pokhara Valley, Nepal, were surveyed in late monsoon season. In the water column at the deepest part of Lakes Phewa, Begnas, and Rupa, total bacteria estimated by the acridine orange direct count (AODC) method changed in the range of 11-2.4X106, 1.7-2.4X106, and 3.2-3.5X106 cells/ml, respectively, and heterotrophic bacteria estimated by the spread plate method changed in the range of 2.5-18X103, 2.0-4.0X103, and 6.9-14X103 CFU (colony-forming units)/ml, respectively. The distribution pattern of free-living and attached heterotrophic bacteria, size-fractionated with a 3.0 um Nuclepore filter, throughout the water column differed among the three lakes. The total and heterotrophic bacteria in the water at inlet were in the orders of 104-105 cells/ml and 103 CFU/ml, respectively, and those in the water at outlet showed a similar number to those in the surface water at each deepest part. The number of heterotrophic bacteria in the sediment at the deepest part was not different among the lakes and in the range of 5.9-8.9X105 CFU/cm3 of wet sediment. All of 178 isolates purified from the three lakes, 64 from the water and 114 from the sediment, were identified to generic level. Only 20% of bacteria isolated from the water were purified, and most of those isolates belonged to Pseudomonas, Flavobacterium, and coryneforms. On the other hand, the bacterial floras in the sediment of the three lakes were dominated by Bacillus.
