Abstract
The enzyme Penicillin G Acylase (PGA) has been produced from Penicillium chrysogenum obtained from spoiled lemon sample. The physico-chemical parameters like carbon source, pH, temperature and media were optimized for higher production of enzyme. The enzyme was purified by ammonium sulphate precipitation followed by Dialysis and Ion-Exchange Chromatography and confirmed by TLC. The purified enzyme was tested for anti-microbial and dye-decolorizing properties. The enzyme showed a clear zone of inhibition when tested against few bacterial pathogens. Then the immobilized enzyme was tested for dye-decolourization activity against Congo red, which showed a very low activity as compared to that of Penicillium chrysogenum.
