    Nitrogen Fixing Bacteria, Azotobacter sp. in Aquatic sediments
    (Society of Fisheries Technologists (India) Cochin, 1987) LAKSHMANAPERUMALSAMY, P
    Non-symbiotic, free living, nitrogen fixing bacteria, Azotobacter sp. was estimated in sediments of estuarine, marine, backwater and mangrove environments of Portonovo. Number of colony forming units (CFU) of Azotobacter sp. was less (5 to 27 cells/g of dry sediment). CFU of total heterotrophic bacteria (THB), actinomycetes and fungi were between 4.1 x 106 and 4.5 x 107, 0.8 x 105 and 4.9 x 105, 1.1 x 105 and 3.8 x 105/g respectively. Mangrove sediments contained more CFU of the above microbial groups.
