| titleOfInvention | A kind of antibacterial silk fibroin membrane by biological enzyme preparation method |
| abstract | The invention discloses a kind of antibacterial silk fibroin membrane by biological enzyme preparation method, belong to field of textile biotechnology.Be intended to solve the fibroin protein film brute force prepared of traditional method low, the shortcoming that film body is hard and crisp, avoid in chemical crosslink technique film-forming process simultaneously and pollute the defect large, fibroin membrane biological safety is low.The present invention utilizes the catalysed oxidn of tyrosine oxidase, while realizing being cross-linked between silk fibroin molecular, the polypeptide antiseptic-germicide (as epsilon-polylysine, L-poly arginine) with primary amine structure is grafted to silk fibroin surface, improve the application performance of fibroin protein film, concrete technology flow process comprises: silk fibroin solution preparation, tyrosinase catalysis oxidation fibroin, the grafting of polypeptide antiseptic-germicide enzymatic, oven dry and film forming.The fibroin protein film prepared by the present invention not only anti-microbial property is improved, and the mechanics mechanical property such as intensity, elasticity of fibroin membrane material is also improved.Compared with the silk fibroin film-forming method based on chemically crosslinked, energy consumption is low, efficiency is high, pollute few advantage to adopt tyrosine oxidase legal system to have for fibroin protein film, is conducive to environment protection. |
