中文摘要	High cost becomes the major obstacle for the industrial application of laccase. Many approaches have been applied to enhance the yield and decrease the cost of laccase. Since flavonoids are the natural inducers for laccase production, in this article, flavonoid-rich plants were taken as the sole substrate for the solid-state fermentation of Funalia trogii (Cui 3676). It indicated that flavonoid-rich plants can effectively promote the production of F. trogii laccase without the addition of inducers. The laccase activity was 42.5 IU g(-1) substrate when kudzu vine root was used as the substrate, which was enhanced by 4.46 times than that when bran was used as the substrate. Meanwhile, the solid-state fermentation of laccase could enrich flavonoids, benefiting their extraction. The content of flavonoids extracted from fermented kudzu vine root and Ginkgo biloba leaves was enhanced by 56.41 and 24.11 %, respectively, compared to the unfermented substrate, and the relative reductive ability and scavenging ability of hydroxyl radicals of flavonoids in the fermented residues were essentially unchanged. Thus, flavonoid-rich plants will become a kind of potential substrate for laccase fermentation which is beneficial in enhancing the yield and reducing the cost of laccase.
