| 摘 要： | 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 colony‘s diameters to the color-zone (d1/d2) and SF are negative correlation, with a correlation coefficient of -0.1476.

| Abstract: | The biodegradated abilities of 13 edible fungi to straw were studied. The results showed that all the experimental fungi exceptTricholama mongolicum had definite biodegradated abilities to the lignin and cellulose of straw. The ldeal fungus for straw degradation was screened
out asPleurotus 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 colony’s diameters to the color-zone
(d1/d2) and SF are negative correlation, with a correlation coefficient of −0.1476.
