Abstract

The present study was undertaken to evaluate bacteriological pollution level of Kabini river water, industrial effluents and soil samples around Nanjangud industrial area, situated near Mysore in the state of Karnataka during 2009. 33 water samples and 13 soil samples were collected and subjected for bacteriological examination. Standard plate count and most probable number tests were performed by presumptive, confirmative and completed tests using respective agars. Further, morphological and biochemical characteristics of the microbial isolates were carried out and bacterial populations were identified as Escherichia coli, Klebsiella sp., Enterobacter aerogenes, Bacillus sp., Salmonella sp. and Pseudomonas sp. Similarly, fungi like Aspergillus niger, Yeast, Rizopus, Penicillium and Curvelarea were identified and Aspergillus flavous and Fussarium sp., were more abundant in soil samples. The MPN in the water samples were observed upto 150 MPN/100ml, which signified undesirable level of water pollution in the area covered and was not suitable for drinking purpose without adequate treatment and appropriate programmes must applied to educate the general populace on the need to purify water to make it fit for drinking and other domestic purposes.
