Distribution of heterotrophic bacteria around Laccadive Islands

Chandrika, V (1996) Distribution of heterotrophic bacteria around Laccadive Islands. In: Second workshop on scientific results of FORV Sagar Sampada, 15-17 February 1994, Kochi.



Distribution of heterotrophic bacteria in water samples collected from surface and 50 m depth in 26 stations around Laccadives in EEZ between 08°50' and 12° and 71° and 74° E onboard FORV Sagar Sampada was studied. The size of colonies isolated from surface water were very small when compared to colonies from 50 m depth. Green fluorescent Pseudomonas was predominant in some stations. Counts ranged from 0.81 x 10^/ml to 2.66 x 10* /ml in surface waters and 0.9 x 10^/ml to 2.20 X 10 /ml in 50 m depth. Night samples harboured less counts when compared to daytime samples. Out of 23 cultures studied Vibrio, Alcaligenes, green fluorescent Pseudomonas formed the main flora and members of Enterobacteriaceae were absent. Both gram-positive and gram- negative bacteria were isolated of which 94.6% were gram-negative rods. Their correlation with environmental parameters are discussed.
