Abstract


In the present investigation, a total number of 57 different actinobacteria strains were isolated from the muthupet mangrove sediment soil samples. Out of 57 isolates, 6 showed inhibitory activity against the fungal pathogens Rhizoctonia solani and Fusarium oxysporum. Among the antagonists, the isolate designated as GACMPT – 57 exhibited maximum inhibitory activity against the test pathogen Fusarium oxysporum (22 mm). The isolate GACMPT-57 was identified as Streptomyces flavomacrosporus by morphological and 16S rRNA sequence analysis. The color of the aerial and substrate mycelia produced by the Streptomyces flavomacrosporus GACMPT - 57 varied with different media.

 

Keywords: Actinobacteria, Streptomyces flavomacrosporus GACMPT-57, Antagonistic Activity, Fusarium oxysporum
