Effect of Different Carbon Sources on the Biological Conversion in Pleurotus ostreatus
[ Objective] To study the effect of com cob, rice straw, cotton seed shell and sawdust as main carbon sources on the biological conversion in Pleurotus ostreatus ,so as to provide references for improving the biological transformation rate of the cultivation materials and search for new materials. [ Method ] Four treatments were set up, four bags for each treatment with three repetitions. The culture materials were respectively put into the high-density PE bags which were 35 cm in length, 20 cm in width and 0.03 mm in thickness. After sterlization, the bags were put into the inoculation room until the temperature was reduced to 25 t. After inoculation, the bags were cultured under darkness at 22 — 26 ℃. When the growth of mycelium filled the whole bags, yellow water started to secrete on the surface of bags, and small primodia appeared,the bags were moved into the mushroom house. The germination of mycelium, its growth, and the time it needed to grow fully in the bags were observed, and the differentiation, meteorological features and yield of fruiting bodies were also observed, the biological conversion rate was calculated according to the formula of Biological conversion rate = weight of fresh mushroom / dry weight of culture materials X 100%. [ Conclusion] The biological conversion of mushroom were 152.19% , 59.30% , 166.38% and 62.28% with the carbon sources of corn cob, rice straw, cotton,seed shell and sawdust, indicating that the biological conversion was greatly different under different carbon sources. [Conclusion] The optimum carbon sources are cotton seed shell, the com cob was secondary, rice straw and sawdust were the worst.
