SDS PAGE studies were done at 76 days of biodegradation. Bacteria with plastic cup substrate have number of protein bands of BF>BD>PF>PP>BS. The Molecular weights of the each protein bands were estimated. The optimum temperature and pH for the biodegradation of plastic were between 300C – 320C and pH 7.5.
