Separation and purification of cellulase from fermentation broth of sewage sludge by Mukhtaruddin, Muna Tasnim, Alam, Md. Zahangir, Mohd. Salleh, Hamzah, Rashid , Shah Samiur

“…In this study, crossflow filteration was used for the purification method using microfiltration (0.45 μm) and utrafiltration (10kD, 5 kD and 1 kD). The results revealed that ultrafiltration with membrane size of 1kD gave the best result for purification of cellulase from fermentation broth of sewage sludge which increases the enzyme activity from 22 U/ml after microfiltration to 50 U/ml after 1 kD of ultrafiltration.…”
