Effects of Co-culturing with Live and Autoclaved Bacillus subtilis on Antagonistic Activity of Marine Fungi against Plant Pathogens
The co-culturing of the fungi with Bacillus subtilis resulted in increased antifungal activity of Eurotium chevalieri and Emericella foveolata extracts but decreased the effects of Talaromyces tratensis and T. stipitatus extracts. Meanwhile, the co-culturing of marine-derived fungi with autoclaved...

description |
The co-culturing of the fungi with Bacillus subtilis resulted in increased antifungal activity of Eurotium
chevalieri and Emericella foveolata extracts but decreased the effects of Talaromyces tratensis and
T. stipitatus extracts. Meanwhile, the co-culturing of marine-derived fungi with autoclaved B. subtilis
resulted in decreased antifungal activity of E. foveolata, T. stipitatus and T. tratensis but slightly
increased activity of E. chevalieri. A significant effect of the co-culture of E. chevalieri and B. subtilis
resulted in an increased antifungal activity compared to the axenic cultures with complete inhibition
of mycelial growth of all the plant pathogens tested, whereas the extract from fungus alone displayed
percentage inhibition ranging from 33.11-100% at 10 g L-1 concentration. Overall, the effect of coculturing with live or autoclaved B. subtilis had positive, negative or no effect on the antifungal activities
of the tested marine-derive fungi against plant pathogens in vitro. |
