We also compared the plasma-treated ODT surface with that after AAc-grafting. Using similar method to immobilize collagen in wet cell system, both surfaces were capable to have collagen immobilized. Nevertheless, their immobilized quantities were significantly different. The most pronounced processes are the participation of oxygen to the plasma-treated ODT surface, the generated oxidative groups, particularly the limited amount of O=C-OH group, are likely to bind with protein molecules.

Compared with the previous method, the improved route can provide directly a spheroid form of immobilized lipase particles of which the size can be controlled by adding non-ionic surfactants during the preparation process so as to increase the recovery rate of enzyme as well as decrease the external diffusional restriction which can diminish the enzyme activity. The improved method can also alter the hydrophobicity and microstructure of the immobilized enzyme matrix by changing the molar ratios of different alkoxyl silanes so as to enhance the enzyme activity by a"surface active effect"and eliminating the internal diffusional restriction.

The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.
