Glucosamine,referred to as Glc N,is a product in which one hydroxyl group of glucose is replaced by one amino group. Glc N is widely present in plants,animals and microorganisms. After research,ammonia sugar has a good effect on the treatment of osteoarthritis,the suppression of cancer,and the recovery of cognitive impairment caused by hypoxia in some animals. This article summarized the application of Glc N in the medical field,and lays a foundation for the further development of Glc N in the field of biomedicine.

[Objectives]Protoplast fusion of two parental strains with weak L-lysine production ability was carried out to obtain new fusion strains with strong L-lysine production ability.[Methods]The effects of bacterial age,lysozyme concentration,enzymolysis temperature and time on the protoplast formation rate and regeneration rate were investigated by single factor *** this basis,with the protoplast formation rate as an index,the protoplast preparation process was optimized by an orthogonal experiment.[Results]Bacterial age and enzymolysis time had a greater impact on the protoplast formation rate,followed by enzymolysis temperature and lysozyme *** optimal process for the preparation of L-lysine-producing Escherichia coli protoplasts was to prepare parental protoplasts from bacterial cells cultured for 15 h in the late logarithmic growth phase by enzymolysis with 0.8 mg/ml lysozyme at 37℃for 180 min and promote fusion with *** order to facilitate the screening of fusion protoplasts,the empty plasmids p ET-28a and p ET-Duet were transformed into L-lysine-producing ***,respectively,and strains p ET-28a-lys01 and p ET-Duet-lys01 were *** strains were then obtained through protoplast ***-resistance KA1-10were screened on plates containing kanamycin and ampicillin,and a high-yielding fusion strain KA8,which produced L-lysine,was screened by fermentation experiments finally.[Conclusions]The results of this study provide a reference method for further improving the yield of L-lysine and other amino acid strains.
