Nutritional factors affecting the antifungal activity of Penicillium steckii of mangrove origin


Jyotsnamayee Sabat and Nibha Gupta*

A fungal strain namely, Penicillium steckii was obtained from saline environment of mangrove plant Avicennia marina and evaluated for antifungal activity in PDA against dieback pathogen of rose. Amendments at the level of different carbon and nitrogen source and their concentrations, inorganic and organic salts resultant into the development of new and modified medium of basal PDA under which our fungi exhibited enhanced level of antifungal activity. Achievement of this medium composition may be useful further in process development to elaborate the antagonistic active principle against plant pathogens.
