Research progress on resource utilization of spent Lentinula edodes sub-strate
Lentinula edodes is the largest yield edible fungus in China,and is an important pillar industry for rural revital-ization.The rapid development of Lentinula edodes industry leads to a large amount of spent substrates,but most of them are directly discarded and burned,which causes serious environmental pollution and waste of resources.Therefore,the resource utilization of spent substrate has attracted wide attention.In this article,based on the analysis of physicochemical properties,the research progress on resource utilization of spent Lentinula edodes substrate was reviewed,including utili-zation modes as edible fungus cultivation matrix,animal feed,organic fertilizer,soil conditioner,horticultural cultivation,biological adsorbent and active material extraction raw material.The main problems in the utilization of spent substrate were discussed.The suggestions were proposed on accelerating the resource utilization of spent substrate,and the research should focus on three aspects of strengthening the material basis,increasing the resource utilization technology,industrial application of supporting facilities and standards.The article aims to provide reference and theoretical basis for the efficient utilization of spent Lentinula edodes substrate.
