摘要: BACKGROUNDFungal laccase (EC 1.10.3.2) is an important enzyme for catalyzing the oxidation of tea polyphenols during the fermentation of tea. (-)-Epigallocatechin gallate (EGCG) is the main ingredient of tea polyphenols. To a certain extent, the oxidation degree of EGCG reflects the fermentation degree of tea. This study preliminarily optimized the conditions for catalytically oxidizing EGCG by Aspergillus sp. trijbl1112 laccase and systematically analyzed the components and contents of the EGCG oxidation products.
