Using feruloyl esterase activity as the response value,the conditions for producing feruloyl esterase by Aspergillus awamori were optimized through single factor tests and response surface experiments.The results showed that the optimal fermentation conditions for feruloyl esterase production by A.awamori were as follows:fermentation time 4 d,glucose addition 14.28 g/L,yeast extract powder addition 3.88 g/L,inoculum 9.70%.Under the optimized conditions,the feruloyl esterase activity reached(3 912.32±34.34)mU/ml,which was 1.89 times that of before optimization.
