ABSTRACT
A total of five different actinomycete isolates were recovered from mine soil samples collected from Salem, Tamilnadu. These were then assessed for their antibacterial activity against five multidrug resistance bacterial wound isolates. All five isolates of actinomycete exhibited antagonistic activity. The zone of inhibition ranged between 11-25 mm. Among the 5 isolates of actinomycetes A5 isolate has highest antibacterial activity against S.aureus and E.coli. Out of five bacterial isolates Pseudomonas aeruginosa was highly suppressed by actinomycetes followed by E.coli. The maximum antibacterial activity was observed on 14th day incubation. The result of primary screening reveals that most of the active actinomycetes isolates were active against gram positive bacteria (S.aureus) than gram negative bacteria. The antibiotic profile of these isolates underlined their potential as a source of novel antibiotics.
