A Cotton Cloth Bioreactor with Immobilized Papain
A cotton cloth strip bioreactor has been designed and fabricated with papain as model enzyme and sol-gel as immobilization method. X-ray photoelectron spectra (XPS) was used to characterize the fiber element before and after papain immobilization. The efficiency of papain bioreactor for the hydrolysis of chitosan was investigated by examining the viscosity decrease percentage (V.D.P.) of chitosan. The results show that the new bioreactor plays a certain role in hydrolyzing chitosan. After using for 4 times, the V.D.P of chitosan is about 3.74％.
