By the use of the method reported in the previous paper, the distribution of nitrogen fixing bacteria was studied in some sea water regions. The standing crop of the bacteria in the water was 10-1-102 cells/mL in inland bays such as Maizuru Bay and Kumihama Bay in Kyoto Prefecture, while the number was quite small in offshore waters in Suruga Bay and Sagami Bay i.e. 0-800 cells/L.
In the water of East China Sea, the open sea, the standing crop of the nitrogen fixing bacteria was as small as 0-400 cells/L, which were detected mostly in the surface water above 100m, and the bacterial number decreased rapidly with the depth below around 100m.
