Heterotrophic bacteria and biochemical activities off the west coast of India

S. Nair, P.A. Lokabharathi, C.T. Achuthankutty

Abstract



Vertical distribution of heterotrophic bacteria and their biochemical activities in the Arabian Sea were studied. Population of bacteria varied from nil to 103 ml. Higher counts were invariably encountered at or close to the surface. Biochemical activities in terms of population density of nitrate reducers, ammonia oxidisers, gelatin liquifiers, hydrogen sulphide producers, fat hydrolysers and thiosulphate oxidisers were estimated
