With water sample collected at several stations in Osaka Bay the ratio in number of bacteria which formed colonies on nutrient-rich medium (Zl-bacteria) to those which formed colonies on nutrient-poor medium (Z/20-bacteria) was examined. The ratio was found to increase in pararell to the concentration of dissolved organic substances probably brought into the bay by environmental pollution.
There were some correlations between taxonomical types of Zl- and Z/20-bacteria and their responses with respect to the colony formation to different concentrations of organic nutrients.
The dominant bacteria of Zl-bacteria in waters containing high concentratoin of organic substances were found to belong to the Acinetobacter group.
