| 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。

| Abstract: | 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 couldn't promote the antibiotic activity of the fermented broth. |
