The liquid fermentation conditions of Rhizopus delemar lipase were studied. The results suggested that the optimal medium be 5?g wheat bran,5?g soybean cake,0.3?g sucrose,and 0.3?g NaNO 3.The best culture condition was the inoculum of 28?℃ and at temperature of 28?℃ were 2?ml(spore concentration 10 7/ml),respectively.The lipase properties of Rhizopus delemar were also studied. The optimum temperature and optimum pH were 35?℃ and 6.5, respectively.The semiactive temperature was 47.5?℃, lipase was relative...
