Bacterial predation by a zooplankton Moina macrocopa Straus was investigated on 3 strains of bacteria, a white strain of Acinetobacter-Moraxella group I and yellow and pink strains of Flavobacterium group I, which were separated from shochu distillery wastewater (SDW). This plankton (I individual mL^<-1>) was inoculated into a SDW medium of each strain at stationary phase, and the number of bacteria was counted every 3 hours for 30 hours. The total organic carbon contents (TOC, ppm) in culture media were changed from 0 to 250 ppm at a fixed temperature of 30 ℃ to observe the bacterial consumption by M. macrocopa. The bacterial consumption by M. macrocopa was highest in the white strain of Acenetobacter-Morarella group I (11.1 × 105 cells mL^<-1>/l ; TOC 100 ppm) followed by the yellow strain (5.1 × 10^5 cells mL^<-1>/l ; TOC 150 ppm) and pink strain (3.5 × 105 cells mL^<-1> ; TOC 200 ppm) of Flavobacterium group I.
