甲壳素的酶法脱乙酰是怎样的

Chitosan (CS) is acetyl chitin N-to take off the product. Because of its rich source, and for natural polymer, has the biological compatibility and security, microbial degradation of excellent performance by all walks of life to attention. In the textile field, with chitosan good antibacterial activity and photographs by development of performance, people on the application study in recent years very active.
This paper makes a study of the chitosan used for pure silk fabric collection, first analysis of the chemical graft copolymerization of finishing effect, which is a method of curing padding the attached to the fabric; At the same time control study the enzyme graft copolymerization catalytic chitosan in silk surface functionalization modification effect, namely by tyrosinase, will chitosan grafted to the enzyme catalytic oxidation of real silk fiber, and after the treatment of fabric dyeing performance, wrinkles resilience, strength and antibacterial properties test.
Studies show that chemical crosslinking method after finishing silk fabric wrinkle resistance improved, and has good breaking strength and the dyeing performance, but at the same time white degree of fabric has dropped, and processing process there are a chemical pollution and thermal pollution; The tyrosinase catalytic crosslinking, chitosan grafted rate had certain improve, fabric wrinkle resistance further improved, and because the process mild conditions, simple steps, and tyrosinase biodegradation more to ensure that this method environmental protection sex. All show that tyrosinase in catalytic silk modification has potential application prospect.

甲壳素和壳聚糖与其它高分子化合物一样,所谓分子量,实际都是不同分子量的同系混合物,只有统计的意义.那怕是存在于同一种蟹壳中的甲壳素,亦因生物合成过程受控因素不同而合成出不同分子量的甲壳素.同时,存在的甲壳素...
