摘　　要：利用阿魏酸乙酯为唯一碳源的选择性培养基和液态发酵产酶试验,对冠突散囊菌进行初筛,确定其是否产阿魏酸酯酶。将其对麸皮进行固态发酵,测定其阿魏酸含量,再对其发酵的黑毛茶进行阿魏酸测定。结果表明,该菌有产阿魏酸酯酶的特性,发酵麸皮和黑毛茶能产1.8 mg/g阿魏酸。该研究结果对茯砖茶的保健功效提供一定的理论依据。Experiment feruloyl esterases productivity from Eurotium cristatum using ethylferulate as the sole carbon source of selective medium and through liquid-state fermentation, then corfirm whether Eurotium cristatum produce femloyl esterase by preliminary screening. Determining the content of ferulic acid by solid-state fermentation of bran, and determining the content of ferulic acid in fermented dack tea. The result shows that Eurotium cristatum has the features of produciong feruloyl esterase, successfully applying on fermentation of wheat bran and dack tea, which can produce 1.8 mg/g ferulic acid. The research results provide certain theoretical basis for Fuzhuan tea health efficacy.
