Abstract

The present study deals with the population of actinobacteria from mangrove environment of Ennore, Kovalam, Mamallapuam, Palaverkadu, East coast of Tamil Nadu, India. Totally 85 actinobacteria species belonging to different genera were isolated from mangrove environment of marine soils. The potential of actinobacteria against selected paddy fungal pathogens such as Athelia rolfsii and Cochliobolus lunatus and to find out the efficient antifungal activity of actinobacteria against paddy fungal pathogens. To evaluate the solubility of the antifungal compounds using different solvents such as chloroform, ethyl acetate, methanol and determine the antifungal efficacy of selected potential actinobacteria by agar well diffusion method. The isolated actinobacteria strains were then screened with regard to their potential of antifungal activity.

Keywords: Mangrove environment, Actinobacteria, Paddy fungal pathogens.
