| 摘 要： | 通过对13种食用菌对稻草生物降解能力的研究,结果表明除蒙古白蘑(Tricholamamongolicum)外,其他12菌株对稻草中的木素及纤维素均有一定的降解能力。其中侧耳(Pleurotus.ostreatus)表现出了很强的木素降解能力及较低的综纤维素降解能力,其木素降解率为17.86%,综纤维素降解率为2.44%,SF指数为7.97,为理想的木素降解菌。其他菌株木素降解率为2.30%~16.54%,综纤维素降解率为5.60%~17.32%,而SF指数均较低,介于0.14~2.24。通过线性回归得出菌落直径与变色圈直径比值(d1/d2)和选择性指数(SF)为负相关,其相关系数r=-0.1476,相关性不大。表5参9。

| Abstract: | The biodegradated abilities of 13 edible fungi to straw were studied. The results showed that all the experimental fungi except Tricholama mongolicum had definite biodegradated abilities to the lignin and cellulose of straw. The Ideal fungus for straw degradation was screened out as Pleurotus ostreatus, which showed a higher degradation ability for lignin (17.86%) and lower degradation rate for cellulose (2.24%), with a Selection Factor (SF) of 7.97. The degradation rates of lignin and cellulose for other fungi ranged from 2.30% to 16.54% and 5.60% to 17.32%, respectively, and the SF was very low in range of 0.14 to 2.24. The ratio of colonys diameters to the color-zone (d1/d2) and SF are negative correlation, with a correlation coefficient of -0.1476. |
