Hot water,ultrasonic wave and microwave extraction methods were used to obtain the schizophyllan from solid fermentation media.The optimum conditions for ultrasonic wave and microwave methods were studied,and the yields and molecular weight of the extracted schizophyllans were compared.The results showed that the optimum process parameters of microwave extraction were as the follows: power/volume 3.5W/ml,the ratio of material to water 1:20,8min.The yield of schizophyllan was 12.32%(g/100g dry basis),70.6% a...
