Abstract

Diversity of antibiotic producing actinomycetes was studied from soil samples collected from various localities of Kodagu district of Karnataka as part of Western Ghats (India). The isolates were identified. In the present study, 158 actinomycetes strains isolated from 15 soil samples of Kodagu district were screened for antimicrobial activities against Gram?positive, Gram- negative bacteria and fungi. Out of 158 isolates, 138 (87%) isolates showed antimicrobial activity. Among these 36 (26%) had antibacterial activities against Gram-positive bacteria, 15(11 %) against Gram-negative bacteria, 87 (63 %) against both Gram- positive and Gram-negative bacteria and 30(22 %) showed antifungal activities. Further, based on preliminary screening, 67 isolates were selected and identified as potential strains of actinomycetes belong to the genus: Micromonospora (26) ; Streptomyces (10); Nocardia (9); Rhodococcus (7); Actinomadura (7); Nocardiopsis (4); Saccharomonospora (2); Psedunocardia (2); Faeinia (1) respectively which belongs to 7 families such as Micromonosporacea, Streptomycetaceae, Nocardiaceae, Micrococcaceae, Thermonosporaceae, Nocardiopsaceae, psedonocardiaceae. The results of this study would provide a base line for further investigation as a source of antibiotics for pharmaceutical interest
