| 摘 要： | 目的研究人毛乳头细胞HSPC016基因重组工程菌的发酵工艺.方法采用德国B.Brau公司C-10型5 L发酵罐批次发酵,通过对能影响工程菌生长和目的蛋白表达的条件如不同培养基、不同葡萄糖浓度、营养物补充、pH及溶氧调节等进行优化,确定合适的培养条件和发酵工艺.结果在优化条件下,菌体单产可达45 g/L,目的蛋白表达量约占总蛋白的18%.结论此发酵工艺可以提高人毛乳头细胞HSPC016/pET-28a( )基因重组工程菌的收获和目的蛋白表达.

| Abstract: | Objective To develop a better fermentation process of the HSPC016 gene of human dermal papilla cell recombinant Escherichia coli BL21. Methods The expression of target protein was analyzed to optimize the composition of the medium, the range of pH values, induction time and other factors in the process of fermentation. Results Under the established condition, 45 g of wet bacteria per liter was obtained and the derivative of target protein was about 18% of total protein in host. Conclusion The established fermentative technique enhanced the collection efficiency and expression of target protein. |
