| 摘 要： | 研究了７种国产大孔吸附树脂对赤霉素的吸附能力，其中Ｓ－８吸附效果较好，赤霉素固／液分配系数为１２．４４，动态吸附容量为４．０６ｍｇ／ｍｌ。８０％丙酮水地赤霉素的洗脱能力较强。用工业赤霉素发酵液进行吸附－解吸实验，分配系数可提高至２５．８８（ＰＨ＝２），动态吸附容量可提高至１０．０２ｍｇ／ｍｌ，赤霉素收率可达９０％以上，且经吸附－解吸循环，可将发酵液中赤霉素浓缩７倍以上。

| Abstract: | Adsorption effects of seven of domestic macroporous adsorption resins for gibberellicacid (GA3) were evaluated. Solid/liquid distribution coefficient of GA3 on S-8 resin is 2.44resin's dynamic adsorption capacity is 4.06mg/ml. Acetone aqueous (80%V/V) solution has thebest elution effect. When GA3 fermentation liquor was adsorbed by S-8 resin, distributioncoefficient and dynamic adsorption capacity increase to 25.88 and 12.02mg/ml respectively(pH=2) in virtue of slating-out effect. Yield of GA3 is above 90% and concentration of GA3could be concentrated 7 times after an adsorption-elution cycle. |
