Chitin and chitosan have been proved to be nontoxic , biodegradable , and biocompatible and are known to have various biological activities including antitumor activity , antimicrobial activity , antifunga ) activity , immune - enhancing effects 壳聚糖是几丁质不完全脱乙酰的产物。几丁质和壳寡糖具有多种生物效应，包括抑瘤、抗菌和免疫增强等。
The red gene and chitinase gene from clone - 5 were ligated together with puc118 ( 2fcwwh i / bap ) , and then transformed into ecoli . jm109 . the recombinant cells exhibited chitinase activity and shew red fluorescence under uv 5的几丁质酶基因与red唱ene连接后再插入质粒puc18中，转入大肠杆菌m109菌株，得到含有几丁质酶基因和红色基因的重组菌株。
