EPS PRODUCTION AND BIOFLOCCULANT ACTIVITY OF BACTERIAL ISOLATES

Nisha P.*, Anu Elias and Anu M. Baby

ABSTRACT

River pollution is the major issues, this study is focused to reduce the same by using bacterial sources. Bacterial species were isolated from water samples and identified as Bacillus sp-1, Bacillus sp-2, Micrococcus sp-1, Micrococcus sp-2 and E coli. These organisms are capable to produce Exopolysacharides. The higher EPS producing organism was Bacillus sp 2 compared to other organisms. In industries the bacterial EPS are used as a bioflocculants. In this study it is revealed that the EPS from the study organisms were showing bioflocculant activities both in deionized water and in Periyar river water. The bioflocculants were also exhibited an antibacterial activity against 3 organisms. Periyar River is being polluted dangerously with industrial wastes, which affects the life of an organisms. The application of the present study is, the EPS produced by these organisms may used as a bioflocculants and can be used to reduce the pollution in Rivers or other water bodies.

Keywords: Bacillus sp-1, Bacillus sp-2, Micrococcus sp-1, Micrococcus sp-2 and E coli.
