ABSTRACT

During this study period, actinomycetes were isolated from karaikal region temple tank Actinomycetes by serial dilution pour plate method. All the actinomycetes were curtained for their antagonistic properties against pathogenic bacterial strains procured from IMTECH, Chandigarh, India. Initially the actinomycetes were primary screened by cross streak method and only two potential actinomycetes were tested subjected to secondary screening which was done by agar well diffusion method. Most of the isolates were found active against Bacillus subtilis, staphylococcus aureus, shawanella putrefaciens, vibrio cholera, and E.coli. Most of the actinomycetes (around 80%) showed good antagonistic effect against most of the tested pathogens and 20% of the total actinomycetes were found non-effective against the test pathogens.
