Abstract
Twenty bacteriophages were isolated from Pavana river water and sewage samples in Pune. Out of all the isolates two bacteriophages were characterized and identified as coliphage (Leviviridae) and staphylophage (Podoviridae). The effect of ultraviolet light and environmental pollutants (detergents and heavy metals) was evaluated on survival of them. The results indicated that, coliphage was more resistant to ultraviolet light than that of staphylophage. Besides, the results obtained from effect of detergents on survival of isolates indicated that coliphage was relatively more resistant against all the detergents other than SDS, however, response of the isolates against SDS was identical. In addition, response of the isolates against heavy metals indicated that MPIC value of Cu was relatively high. While, MPICs of Cd and Hg were relatively low and the MPIC value of Zn for coliphages was high than for staphylophage. Therefore, based on foregoing evidence the present study interpreted that probably coliphage is relatively more resistant to radiation and environmental pollutants than staphylophage, which is related to their genome and structures.
