Abstract:

{Soil samples were collected from three sites (Wadi-El-Natrun, Kafr-El-Sheekh and Mallahat Road) located in Cairo-AlexandriaAgriculture Road, Egypt. The total fungal counts allover the road was 755 colonies, constituting ten fungal species (Alternariaalternata, Aspergillusflavus, Aspergillusnidulans, Aspergillusniger, Aspergillusterreus, Fusariummoniliforme, Penicilliumchrysogenum, Penicill-iumpurpurogenum, Phomaherbarum and Rhizopusoryzae). The most potent fungal species producing pigmentsalong the road were A. nidulans, F. moniliforme, P. purpurogenum and P. herbarum. Comparative sensitivity to different light wavelengths and radiation (laser, gamma and ultraviolet rays) on growth and pigment production in the four selected fungal species wasestimated. Optimization of physical and nutritional factors on growth and pigment production was carried out. A steady increase in theantioxidant activities was showed in all four tested pigments producing species with raising the phenol contents. The extracellularpigment of P. purpurogenum was found to be more effective against some pathogenic microbes and might have a potential role inpharmaceutical drug industry. The identification of the structure of unknown P. purpurogenum pigment was detected using UV andFTIR spectra, and indicated that it is an phenolic compound and has broad stretching OH
