Microbial strain for lignin degradation and application thereof

The invention discloses a microbial strain for lignin degradation and application thereof, and belongs to the field of waste treatment by a microbiological method. The melon sphingomonas strain obtained through separation can adapt to strong acid and strong alkali wastewater conditions generated in industrial production, can well grow and propagate, has a good degradation effect on lignin, and can reduce the lignin content in liquid wastewater by 5-25%. Meanwhile, lignin in the agricultural and forestry wastes can be removed, so that the content of the lignin is reduced by 3-10%, and the method has a very wide application prospect in treatment of refractory substances in the agricultural and forestry wastes and is also beneficial to ecological environment protection and sustainable development. 本发明公开了用于木质素降解的微生物菌种及其应用，属于微生物法处理废弃物领域。本发明分离得到的一株瓜类鞘氨醇单胞菌能够适应工业生产所产生的强酸、强碱性废水条件，能够很好地生长繁殖，并且其对木质素有较好的降解效果，可使液体废水中的木质素含量降低5～25％。同时能去除农林废弃物中的木质素，使其含量降低3～10％，对于处理工农业废物中难降解物质有非常广阔的应用前景，也有利于生态环境的保护及可持续发展。
