Solid-state culture of Aspergillus niger on support

The growth kinetics of Aspergillus niger on a solid support i.e. sugarcane bagasse, impregnated with a liquid glucose medium, were investigated under different culture conditions. The water activity of the medium, the amount of spore inoculum and the support particle size were shown to be critical factors for mold growth. The elevated rates of growth observed with high substrate concentration media demonstrated the feasibility of the method for culturing filamentous fungi.
