. Sichuan University – leather by way of the identification of key innovation project on June 7, from Sichuan University, Chengdu Di-O collagen leather higher-tech Co. , Ltd.
completed a major innovation project “Preparation of contemporary biotechnology series leather higher-specific enzyme” in Leather Floor Conference Space, Sichuan University, Sichuan Science and Technology Department by the Deputy Director Liu Xiaoheng chaired authentication meeting held. Identification (with proof) Committee from Beijing, Chongqing and other locations of specialists and professors of seven members: Lu Xu Yong (Professor, Senior Engineer), lactic (professor, Ph. D.
) as deputy chairman, members are Yong-Jin (Researcher), He Kaize (Fellow) , Ye Hong (Senior Engineer), Li Kaihua (senior engineer), and Dealing With the (senior engineer). Following listening to the project leader Li Zhiqiang (Professor, Ph. D.
, Pro-Vice-president of Sichuan), but Weihua (Researcher, PhD) were working for a long, technical report, the appraisal committee to the questions, very carefully assessment and lively discussion, and observation of a lot of sort of higher-distinct enzyme in-kind samples. Unanimous specialist opinion as follows: 1, independent analysis and improvement of the cross-linked collagen with chromium as the active carrier of affinity chromatography, and used it for the initial time the two types of leather used enzyme (166 neutral protease and AS1. 398 neutral protease) Purification and elements identified and developed on this basis with out collagenase enzyme hair removal – hair removal enzyme safety of new merchandise, is an international initiative for the implementation of enzymatic hair removal process, to eradicate the further pollution of sulfide laid a solid foundation.
two, independently created a type of relaxation activity of acid orange markers of collagen collagen as substrate hydrolysis activity analysis. The approach is convenient, fast, sensitive, revolutionary. 3, using genetic engineering strategies on acid protease gene, molecular modification, prepared chrome soft enzyme EC.
The product is an international initiative. The application final results show that the item can boost the quality of leather and increase softness of leather, leather and then raise the rate also. four, independent study and development of enzyme complex liming auxiliaries EA and cold soft enzyme EB-1, its complementary elements of efficiency, an international initiative.
Enzyme complex liming auxiliaries EA has drastically improved milk of lime suspension, can be totally separated and loose collagen fibers, lessen or remove the negative parts as properly as the benefits of the price enhance was leather. five, innovative design and style a range of harmless inorganic compound composed of the system efficiency of enzyme additives. The topic of efficiency in the improvement of a productive series of leather on the basis of particular enzymes, combined with genetic engineering, enzyme engineering technologies, created with advanced technology and sophisticated manufacturing technologies leather combination, constructed of leather cleaning approach model proposed set of enzyme-primarily based bio-tanning technology, with the significance of sustainable development of leather.
Application on the subject developed a series of exclusive leather and efficient enzyme, is anticipated to replace toxic and hazardous chemical substances, substantially minimize the tannery pollution can boost product quality, improve the price was leather. The series is expected to modify the face of leather production, access to significant economic and social benefits. Goods which have been place on the market by a lot of enterprise applications, has made substantial economic and social positive aspects.
The scientific and technological achievements to the international sophisticated level, the core technology has reached the international advanced level. Proposed series of special high-particular enzyme industrialization as quickly as achievable, in order to promote industrial upgrading, and business to make higher contributions to scientific and technological progress. .
