褐煤生物转化及其研究展望

Lignite bioconversion and research prospect

综述了褐煤生物转化的3种方式:解聚、溶解和利用,以及目前对转化方式的机理的研究结果和作用菌种。褐煤的解聚主要是酶的作用,如木质素过氧化物酶、漆酶等;褐煤的溶解已知有碱作用、螯合剂作用和水解酶作用等。作用的微生物主要是属于担子菌、子囊菌和半知菌的真菌,大部分俗称白腐真菌。虽已经取得不少研究成果,但该领域的研究仍处在初始阶段,离工业利用尚远。

This paper reviewed the whole three bioconversion ways of lignite：biodepolymerzation, biosolubilization and utilization. Lignite biodepolymerzation mainly attribute to the enzyme reaction like the lignin peroxidase and laccase. Alkali, chelating agent and hydrolase mainly causes the biosolubilisation. The microbe involved in lignite bioconversion are basidiomycete, ascomycete or deuteromycete,which most belong to the white rot fungi. It has got many significant reseach results in this area, however, there are still some notable problems need to asslove.
