The distribution of phosphatase-producing bacteria in Lake Shinseiko and their physiological properties were studied. The activities of alkaline phosphatase were 20-80 nmol•1•¬-1¥min-1 for unfiltrated lake water and 10-25 nmol•1•¬-1min-1 for the filtrates. The number of phosphatase-producing bacteria was calculated to be 100-10000 cfu¥ml-1. The bacteria were mostly found in the epilimnion during the stratification period and uniformly distributed vertically in the water column during the circulation period.
