摘　　要：木薯渣因其所含粗纤维经有效降解之后可以变废为宝,节省资源又保护环境而受到国内外学者的广泛关注。对木薯渣再利用方面的研究已经成为近年来一大热点,微生物降解是提高木薯渣利用率的一个有效途径。从木薯渣降解再利用角度出发,综述了木薯渣的用途、降解机理以及温度、pH值、含水量等重要影响因素。阐明了在合适的环境条件下,筛选有效降解微生物是提高木薯渣利用率的关键因素。同时展望了调制复合酶系在降解木薯渣纤维素上的应用,以及改造、合成以及重组降解酶以提高和推广木薯渣纤维素分解的必要性。Cassava residue,which brings serious harm to the environment due to its toxicity and stability,however,can be degraded to useful material.So nowadays it is greatly concerned all over the world and the research on reuse of cassava residue has been a hot issue in recent years.Microbial degradation is an effective way to improve its utilization.Focus on the degradation and reuse of cassava residue,the paper mainly summarized the application and degradation mechanism of cassava residue,and also the important environmental factors influencing its microbial degradation.The article elucidates that the screening of effective degradation microorganisms is the key factor that can improve the utilization of cassava residue.The environmental condition brings great influence on the degradation of cassava residue.Finally,the application of modulating compound enzyme to the degradation of cassava residue cellulose,as well as the necessity of transforming,synthesizing,and restructuring degradation enzyme is recommended.
