Plant materials as probable growth promoters for certain fungi

Plants and plant products purchased from the local markets of Khartoum State in the Sudan were tested as culture media (solid and liquid) for cultivation of fungi. The pH values of the plants extracts were determined. It was found that the plants extracts varied in their pH values, semi- natural, alkaline and acidic. Curvularia lunata, Aspergillus niger, Aspergillus flavus, and Fusarium oxyaporum were screened initially for growth in 16 different plants extracts (broth media). These strains were able to grow on all of these extracts, but with some variations. The plant extracts exhibited very good growth for these strains were selected for formal assessment of growth. These plants extracts were Tomato, Aubergine, Wheat flour, Dukhun and Pigeon pea, amended with agar powder to solidify. The results showed that all the fungal, species namely C. lunata, A. niger, A. flavus and F. oxyaporum, were capable of growth on these extracts media (solid) and Potato Dextrose Agar (PDA) as control. The growth varied with the different isolates as reflected by colony diameters.
