赤霉素制备

1.由gibberella fujikuroi菌种培养液通入无菌空气发酵后提炼精制而得。接种量为最终发酵罐液的4%，在温度为25～30℃下，不断搅拌和通风，搅拌过程中，用十八碳醇做抗沫剂。发酵完毕后，溶液用氢氧化钡沉淀并过滤。然后在阳离子交换树脂上，在pH=50时吸附并用NH3或其他碱性缓冲液洗脱，再进行精制处理而得。

2.赤霉素可用发酵方法生产。利用赤霉菌在麸皮、蔗糖和无机盐等培养基中进行发酵，赤霉菌代谢产生赤霉素，发酵液经溶媒提取、浓缩即得。

3.现都采用发酵法制取。发酵液经过离子交换树脂 Amberlite XAD-4柱，水洗至干净后，以90%丙酮的水溶液洗脱，收集洗脱液并且浓缩干燥，成品中赤霉酸含量90%以上。
