摘　　要：从辣木(Moringa sp.)中分离得到一株内生真菌(Aspergillus sp.),其发酵液对金黄色葡萄球菌和绿脓杆菌的生长有很强的抑制作用。曲霉ly14发酵液抑菌效果的最适碳源是麦芽糖,最适氮源是玉米浆,最适初始pH为5,最适装液量为50 mL和最适培养时间160 h,但生长因子(叶酸和VB12除外)和无机盐离子并不促进发酵夜得抑菌效果。An Aspergillus sp. strain of endophytic fungi was isolated from Moringa sp.. The fermented broth of the strain strongly inhibited the growth of Staphylococcus aureus and Pseudomonas aeruginosa . It was proved in our test that the optimum C - souce, N - source, initial pH, medium capacity and culture period were maltose, corn steep liquor, 5.0, 50mL and 160h for inhibiting effect of the fermented broth, but the growth factors （ except FH4 and VB12 ） and inorganic ions couldnt promote the antibiotic activity of the fermented broth.
