为寻找大孔吸附树脂对粘性红圆酵母产类胡萝卜素的最佳纯化条件,比较了6种大孔吸附树脂对类胡萝卜素的静态吸附能力,并对所选择树脂的吸附最佳条件和解吸条件进行了研究。结果表明,DS-401型大孔吸附树脂具有最佳的吸附和洗脱参数,其最佳工艺为在pH为6.0、温度为25℃、时间为1 h的条件下吸附率最大,可达80.58%,此时选用100%石油醚做解吸剂,于30℃解吸1 h,解吸率最大,可达95.32%。

An optimal macroporous adsorption resin was chosen to purify the carotenoid produced by Rhodotorula mucilaginosa.And its conditions of static adsorption and desorption were studied in this paper.The result show that DS-401 resin was of excellent adsorption and desorption performance to carotenoid.The optimal adsorption condition was pH6.0,25 ℃,1 h,adsorption rate was up to 80.58 %.The optimal desorption condition was 30 ℃,1 h while 100 % petroleum ether was taken as...
