• In order to observe the effect of hydrostatic pressure on the deep-sea bacterial population, growth experiments were conducted with water samples collected from depths of 0, 2000, 4000 and 6000 m at two locations in the northwest Pacific Ocean. When the water samples were incubated under different pressures at 2℃, good growth was observed at pressure levels of the depths where the samples were collected. These results suggest that the bacterial population at each depth of the deep-sea is well adapted to the environmental conditions, as has been suggested by A. A. YAYANOS (Proc. Natl. Acad. Sci. U.S.A., 83, 9542, 1986) with pure culture isolates from the deep-sea.
