  • Abstract

    Marine actinomycetes were isolated from sediment samples collected from of eight mangrove species of Pitchavaram mangrove ecosystem. The actinomycetes population ranged between 2.1 X 104 and 6.4 X 104 cfu g-1 of dry sediment. Maximum actinomycetes population was noted in rhizosphere of Avicennia marina and the minimum with Excoecaria agallocha. About 50% of the isolates showed activity against S. aureus followed by B. subtilis, E. coli, V. cholerae, K. pheumoniae, P. vulgaris and S. typhi. Bioactive compound from one potential strain Rh1 was produced using soybean meal medium. The culture filtrate and its ethyl acetate extract showed 8-15 mm and 12-20 mm inhibition, respectively. Based on the studied phenotypic characteristics, strain Rh1 was identified as Streptomyces fradiae (Rh1). Purification and characterization of potential actinomycetes strain Rh1 is in progress, to prove its potential further.
