“…Their bacterial floras also showed the highest diversity during October and November, when suspended particles such as dead organisms and detritus seemed to increase with decreasing algal biomass. SIMIDU et al (1971SIMIDU et al ( , 1977, RAMSAY (1977), SOCHARD et al (1979), MATSUDA (1974), andTANAKA et al (1980) evidenced clear differences in the bacterial floras developed on different kinds of suspended particles, such as phytoplankton, zooplankton, particulate detritus, and particulate inorganic matter, in natural aquatic environments. FU-KAMI et al (1981), KOGURE et al (1982), and reported that the particle-associated bacterial flora fluctuated during the decomposition process of phytoplankton cells or detritus particles under experimental conditions.…”

The bacterial floras in four size fractions (>35 ƒÊm, 35-5 ƒÊm, 5-1 ƒÊm, and < 1 ƒÊm) of suspended particles separated by size fractionation from the surface water of Himon-ya Pond, a Hypertrophic pond in Tokyo, were investigated from August 1978 to January 1979. The bacterial flora in the >35 ƒÊm fraction (bacteria associated mainly with the mucilage of Microcystis colonies) showed a simple generic composition during the Micro-Acinetobacter at each sampling time. These results suggest the existence of different bacterial floras among different size fractions of suspended particles in the pond water.

The planktonic bacterial populations in the surface water of the hypertrophic Himon-ya Pond were separated into four fractions ( >35 pm, 35-5 pm, 5-1 pm, and < 1 pm) by size fractionation of suspended particles in the water. The seasonal variations in bacterial numbers over a two year period differed for each of the four fractions. The bacterial counts in the >35 pm fraction were mainly dependent on the biomass of Microcystis colonies. Their peaks were observed in summer. I n the 35-5 pm and 5-1 pm fractions, several peaks in bacterial numbers were observed, influenced by the quality and quantity of the particles associated with the bacteria. The bacterial counts in the i 1 pm fraction contributed a high proportion of the total throughout all seasons except summer.
