Application of agilawood endophyte in catalyzing chromone to produce hydroxychromone

The invention provides application of agilawood endophyte in catalyzing chromone to produce hydroxychromone, and belongs to the technical field of microorganisms. The agilawood endophyte disclosed by the invention is Diaporthe discoides GX11-3, and the agilawood endophyte disclosed by the invention is the Diaporthe discoides GX11-3. The preparation method comprises the following steps: transferring a discoid-like m-shell strain GX11-3 to a PDA plate, and culturing; the method comprises the following steps: transferring mycelia of a discoid m-shell strain GX11-3 into PDB, and fermenting to obtain pure strain fermentation liquor; chromone and the pure strain fermentation liquor are mixed, fermentation continues, and fermentation liquor containing hydroxychromone is obtained. The method for obtaining the hydroxychromone is high in efficiency, good in catalytic effect, accurate in catalytic site, simple in reaction system and suitable for large-scale production. 本发明提供了一种沉香内生菌在催化色酮产羟基色酮中的应用，属于微生物技术领域。本发明所述沉香内生菌为盘状
