中文摘要:
      以海南粗榧内生真菌细极链格孢CH1307发酵产高三尖杉酯碱的产量为指标,采用响应曲面法分析葡萄糖质量浓度、硫酸镁质量浓度、复合维生素B质量浓度及摇床转速对该菌株液态发酵的影响。结果表明,细极链格孢CH1307液态发酵产高三尖杉酯碱的关键因子值分别为葡萄糖32.022 6 g·L-1,硫酸镁0.096 6 g·L-1,复合维生素B 0.123 9 g·L-1,转速146.474 2 r·min-1时CH1307发酵最好,代入方程的HHRT产量为190.637 0 μg·L-1。
英文摘要:
      Homoharringtonine (HHRT) was produced from Alternaria tenuissima CH1307, an endophytical fungus of Cephalotaxus mannii Hook.f through fermentation. Four factors such as the concentrations of glucose, magnesium sulfate and vitamin B compound and the rotating speed were analyzed by using response surface methodology to determine their effect on fermentation of the fungus CH1370. The best operating conditions resulted to be 32.022 6 g·L-1 for glucose , 0.096 6 g·L-1 for magnesium sulfate and 0.123 9 g·L-1 for vitamin B compound as well as 146.474 2 r·min-1 for the rotating speed, and 190.637 0 μg·L-1 of HHRT were produced from this fungus when the values of the four factors were entered into a formula established.
