Metabolic engineering of lignin degradation pathways in bacteria

木质素是一种芳香杂聚物，约占植物细胞壁木质纤维素的15-30%，是地球上最丰富的可再生芳香原料。木质素的芳香族含量代表了一种未开发的资源，可转化为塑料、材料和精细化工生产所需的可再生芳香族化学品。该项目的目的是为细菌木质素降解的代谢工程开发新的工具，并利用它们通过对细菌木质素降解物进行基因改造来产生新的生物产品。

Lignin is an aromatic heteropolymer found as 15-30% of plant cell wall lignocellulose, and is the most abundant renewable aromatic raw material on Earth. The aromatic content of lignin represents an untapped resource for conversion to renewable aromatic chemicals needed for plastics, materials and fine chemical production. The aims of the project are to develop new tools for metabolic engineering of bacterial lignin degradation, and to use them to generate novel bioproducts via genetic modification of bacterial lignin degraders.
