10.22376/ijpbs.2019.10.1.p1-12 Volume 6 Issue 1 2015 (January - March) Nearly sixty isolates of bacteria, fungi and actinomycetes were selected from ten soil samples. The soil samples were collected from the Thiruporur forest area. Among the sixty isolates, we selected twenty isolates of actinomycetes. These actinomycetes were isolated from soil samples by the serial dilution method. They were subjected to primary screening. After the primary screening three actinomycetes named A3, A7 and A20 were selected on the basis of zones of inhibition produced around them. This was followed by secondary screening against lessThan i greaterThan Aspergillus fumigatus lessThan /i greaterThan (streak culture) which was the target pathogen. The isolate A7 showed prominent antifungal activity after the secondary screening, hence it was selected for further study. It was subjected to morphological and molecular methods to reveal its identity. R.V.SHALINI AND DR.K.AMUTHA Terrestrial, Streptomyces, Aerial mycelia, Melanin, Antifungal activity. 750-758
