Ajmal Khan Biología THB phosphorous microbial loop Bay of Bengal biogeochemical cycle Microorganisms play a vital role in the biogeochemical cycles of various marine environments, butstudies on occurrence and distribution of such bacteria in the marine environment from India are meager. Westudied the phosphate solubilizing property of bacteria from the deep sea sediment of Bay of Bengal, India, tounderstand their role in phosphorous cycle (and thereby the benthic productivity of the deep sea environment).Sediment samples were obtained from 33 stations between 10°36 N 20°01 N and 79°59 E 87°30 E along11 transects at 3 different depths i.e. ca. 200 m, 500 m, 1000 m in each transect. Total heterotrophic bacterial(THB) counts ranged from 0.42 to 37.38x104 CFU g-1 dry sediment weight. Of the isolates tested, 7.57% showedthe phosphate solubilizing property. The phosphate solubilizing bacterial genera were Pseudomonas, Bacillus,Vibrio, Alcaligenes, Micrococcus, Corynebacterium and Flavobacterium. These strains are good solubilizers ofphosphates which ultimately may play a major role in the biogeochemical cycle and the benthic productivityof the Exclusive Economic Zone (EEZ) of Bay of Bengal, because this enzyme is important for the slow, butsteady regeneration of phosphate and organic carbon in the deep sea.
