Abstract:
With cotlonseed shell as major medium,taking Pleurotus eryngii as research object,lignocelluloses degradation,respiration consumption and absolute biological efficiency were determined at different stages of development from Pleurotus eryngii cultivated on the cottonseed shell medium in bag.The results showed that P.eryngii degraded cellulose and hemicelluloses weekly and lignin strongly,so it belonged to whiterot fungi.Nonlignocellulose was principally used at the stage of mycelia growth.However,lignocelluloses were the main carbon source for the fruiting stage of the fungus.At the end of cultivation (70 d),the medium reduction (dry weight) was 30.65%,the respiration consumption was 22.67%,and the absolute biological efficiency (biomass of fruit bodies) was 7.98%.The content of cellulose and hemicellulose in residue of P.eryngii was higher than cottonseed shells,so it has reuse value.
