Abstract:To evaluate the efficiency of Tremella fuciformis cultivation by using oilseed rape straw，the fresh weights，growth times，the yields of crude polysaccharide and their basic components of Tremella fuciformis were analyzed.Results showed that when the medium consists of oilseed rape staw and cottonseed hull with the proportion of 4 ∶6 （mass ratio），the fresh weight of Tremella fuciformis was increased to 430.16 g and was significantly（P＜0.05）higher than that cultivated by traditional medium of using only cottonseed hull，while the growth time for the sporocarp maturation was shorten to 31.18 d and was not significantly different with that cultivated by using only cottonseed hull.Besides，the yield of its crude polysaccharide were 34.76 %，which was significantly（P＜0.05）higher than that cultivated by using only cottonseed hull.As for the basic components of crude polysaccharide，when the medium consists of oilseed rape staw and cottonseed hull with the proportion of 4 ∶6 （mass ratio），the content of polysaccharide and glucuronic acid and the molecular weight distribution were similar to that cultivated by using only cottonseed hull.
