近年来,各地纷纷利用棉籽壳栽培食用菌,在代料栽培方面迈出了可喜的一步。但棉籽壳中含有有毒的游离棉酚,很多人担心以棉籽壳为基质栽的平菇,棉酚含量超过食用标准,会致畸、致癌。为此,我们从1982年开始对平菇、凤尾菇中的残留棉酚进行了测定。材料与方法 (一)供试菌种:平菇(Pleurotus sp)1号、12号及凤尾菇(Pleurotus sajor-caju)菌株系本所收集的品种评比菌种。将供试菌种制成棉籽壳原种,部分用于测定,部分接种于棉籽
In recent years, various places have used cottonseed shell cultivation of edible mushrooms, took a gratifying step forward in the field of material cultivation. However, cottonseed hulls contain toxic free gossypol, many people are worried about cottonseed mushrooms as the substrate planted mushrooms, gossypol content than food standards, can cause teratogenic, carcinogenic. To this end, we started from 1982 on Pleurotus ostreatus, gorgonia in the determination of residual gossypol. Materials and Methods (I) Species to be tested: Pleurotus sp No. 1 and No. 12 and Pleurotus sajor-caju strains were collected strains of the species. Test species will be made into seed cottonseed stocks, some for the determination, inoculation of cottonseed
