Chandrika, V and Nair, P V Ramachandran (1994) Seasonal variations of aerobic heterotrophic bacteria in Cochin backwater. Journal of the Marine Biological Association of India, 36 (2). pp. 81-95.
The occurrence and seasonal distribution of aerobic heterotrophic bacteria in water and sediments and their ecophysiology and biochemical character, were studied for a period of three years - 1972-73, 1974-75 and 1975-76 in Mhin Backwater. The total counts between one station and the other did not show significant diffence while the counts between months did. The distribution was characterissd by overdispersion. Among 920 strains selected from this tropical marine environment in different months in the three years period, 23 strains were lost during purification and retransferring procedures and classified into 8 genera. The genus Alcaligenes was found to be the dominant genus in all the seasons. Data on tdmperature related bacterial density indicated that there are very few, true psychrophilic bacteria in Cochin' Badwater and sediments. The relationship between baderial density and nutrients are discussed.
