Compare of Heterobasidion Insulare with white rot fungi in Degradation wastewater of Pesticide plant

Abstract

Abstract.A Heterobasidion Insulare ability to degrade in different culture conditions was investigated and compared to that of P. chrysosporium. The results indicated that H.Insulare isolate is more efficient than P. chrysoaasporium in decolorizing in the presence of added nutrients. H.Insulare is able to remove more than 50% of the color and phenols from Pesticide plant with in 6 days of incubation, whereas P. chrysosporium needs more than 12 days to reach similar results in the same conditions. Many factors affecting the treatment of diluted waste water of Pesticide plant (30%) by H.Insulare were studied, including the effects of added nutrients, initial pH, and temperature and inoculated biomass. Once the optimization of 30% waste water of Pesticide plant biodegradation process had been set up, higher waste water of Pesticide plant concentrations (50%) were tested. The results show that the fungus is capable of reducing all parameters analyzed at least 60%, after only 9 days of growth.
