ABSTRACT
Based on M9 culture medium,the concentration of ingredients of culture medium was optimized for the fermentation of pNSR32/BL21(DE3),the engineering bacterial with spider silk protein,and lactose as an inducer.The condition of optimum culture medium was obtained for the expression of the high molecular weight recombinant spider silk protein by using orthogonal and individual factor experimental design.The result was showed that the optimum culture medium was consisted of 0.3% glycerol,3% yeast,0.75% tryptone,0.05%(NH_4)_2SO_4 and a little inorganic salt_.It was confirmed that the optimum culture medium will benefit the growth of bacterial and expression of recombinant spider silk protein.The production level of propose protein will attain at 20% of the total proteins in the fermentation.
