Quantitative and qualitative investigations of organic phosphorus decomposing bacteria in the central Adriatic

Abstract

       The distribution and some properties of organic phosphorus decomposing bacteria were studied seasonally at three stations of the Central Adriatic during 1975. Their distribution and relation to other heterotrophic bacteria were analyzed by standard plate method on four media (Beef-pepton-agar, Tyler, Menkina and the medium with mud extract). Organic phosphorus decomposing bacteria were found in all the collected samples and their percent to other heterotrophic bacteria was observed to vary in different water and mud samples. Mean percent values in water environment ranged from 8. 1 to 14.8%, and in the sediments from 20.6 to 35.4%.
