Optimize the fermentation medium of Schizochytrium limacinum mutant strain to produce DHA using single factor experiment associated with response surface design.First,after the single factor experiment,the main components of fermentation medium are glucose,sodium glutamate,yeast extract,and sea crystal.Through response surface optimization,it is found that when the contents of glucose,sodium glutamate,yeast extract,and sea crystal in fermentation medium are 85.99,11.86,8.16 and 20.16 g/L,respectively,the theoretical prediction of DHA production is 6.10 g/L.After optimizing,the production of DH...
