Assessment of Biological Decolorization and Degradation of Industrial Effluents by Aspergillusniger Agrocybecylindracea and Pleurotus Florida

Biodegradation of azo dyes by the white rot fungus such as Agrocybecylindracea, Aspergillusniger and Pleurotusflorida and to identify the chemical compound by GCMS characterize the decolonization by Ligninolytic enzyme by varying PH, temperature and incubation time. To identify the toxic elements present in textile and tannery industrial effluents before and after treatment of ligninolytic enzymes. The WRF with maximum Laccase activity was used as a source of enzyme to test the efficiency in decolorization of textile and tannery effluents. The textile effluent was decolorized by using Aspergillusniger, Agrocybecylindracea and coculture of these two organisms by varying the biomass concentration. Constant volume (100ml) of effluent was effectively decolorized by 3mg/100ml of coculture of A.niger and A.cylindracea.The tannery effluent was effectively decolorized at 2mg/100ml of the biomass of Pleurotus Florida. Textile and tannery effluent was effectively decolourized by coculture of A.niger and A.cylindracea and P.florida. The optimum temperature, PH and incubation time was found to be 500C, 7 and 210 minutes respectively for textile effluent decolorization. The optimum condition for tannery effluent decolorization was found to be 400C, 6 and 180 minutes. After treatment of effluents, Atomic Absorption Spectroscopy and HPTLC results revealed that the toxic metals have been reduced substantially from the effluent by the action of ligninolytic enzymes.
