Isolation, identification and seasonal distribution of bacteria in Dal Lake, Kashmir

This research work determined the bacteriological characteristics of the waters of Dal Lake, Kashmir. Bacteriological studies were carried out from April 2010 to March 2011 at eight different sites. Out of total 894 bacterial colonies isolated, 11 isolates of bacteria namely Klebsiella pneumoniae, Citrobacter freundii, Enterobacter aerogenes, Escherichia coli, Vibrio cholerae, Serratia marcesens, Pseudomonas aeruginosa, Staphylococcus aureus, Micrococcus luteus, Bacillus spp, and Salmonella spp. were studied for isolation, identification and seasonal distribution in Dallake waters.. Out of these species, E. coli was most abundant (15.77%) followed by Enterobacter aerogenes (12.19%), Bacillus spp (11.96%), Staphylococcus aureus (10.85%), Micrococcus luteus (10.17%), Pseudomonas aeruginosa (8.27%), Klebsiella pneumoniae (6.71%), Vibrio cholerae (6.59%), Salmonella spp (6.15%), Serratia marcesens (5.92%) and Citrobacter freundii (5.59%). Highest number of colonies 155(17.33%) were obtained from site PKB followed by DLG-136 (15.21%), GB126 (14.09%), NL-116 (12.97%), TBN-113 (12.63%), BHN-107 (11.96%), HB-74 (8.27%), BD-67 (7.49%).
