Abstract
An attempt was made in the present study to find out the biodegradation of the penicillin-G wastewater for the various operational conditions such as, initial substrate concentrations (13000, 10000, 6000, 4000 and 2000 mg of COD/l), agitation, addition of nutrients (glucose and ammonium chloride) and biomass dosages (2, 3, 4 and 5 g) in batch reactor using immobilized cells of Phanerochate chrysosporium, a white rot fungi. The highest COD removal efficiency was found at the initial substrate concentration of 2000 mg COD /l, under static condition using 4 g of biomass in the absence of nutrients i.e., carbon and nitrogen sources. The Langmuir and Freundlich adsorption models fitted well with the equilibrium data of the process studied. It was also observed that the experimental kinetic data followed the first order rate expression.
