摘　　要：木质素为天然的芳香族聚合物,是自然界第二大丰富的可再生碳源,占木质纤维素干重的15%~30%。因木质素富含芳香族结构,故其具有极高的应用价值。生物法转化利用木质素具有专一性强和环境友好等特点,使得木质素生物炼制成为研究热点。本文根据国内外研究进展,从木质素降解酶的研究现状、芳香族化合物胞内代谢途径及木质素生物基化学品研究进展等几个方面做了综述。Lignin is the most dominant natural aromatic polymer and the second most abundant natural renewable carbon source, which constitutes approximate 15%- 30% dry weight of lignocellulose. The lignin biorefinery has been becoming the focus of lignocellulose utilization due to the specificity and environmentally friendly characteristics. In the present paper, the advances of lignin biorefinery are reviewed, including the lignin degradation enzymes, metabolic pathways of the aromatic compounds and the advances of lignin bio-based chemicals.
