Abstract

Actinomycetes were isolated from agricultural and non-agricultural farm soil samples in the Sangli district of Maharashtra. 60 actinomycetes were isolated from 30 soil samples, with only three isolates from agricultural soil and three from non-agricultural soil displaying inhibitory activity. Soil samples from non-agriculture farms yielded a higher percentage of antagonistic actinomycetes (10%) than those from agriculture farms (2 %). Three non-agricultural isolates with high inhibitory activity were tested for their inhibitory profile against three human test pathogens, Salmonella typhi, S. paratyphi A, and paratyphi B. The actinomycete isolate INA - 53 exhibited a high degree of inhibitory activity against all the test pathogens both in terms of the number of test pathogens inhibited and the zone of inhibition as compared to the standard antibiotic used that is streptomycin. INA - 53 was identified to be belonging to the genus Streptomyces spp. The results suggest that non agriculture soil samples are rich in organic matter with a high C:N ratio are the potential source of antagonistic actinomycetes and a large number of antagonistic actinomycetes producing anti-microbial compounds can be isolated from non agriculture soil.
