| 摘 要： | 为提高D-阿拉伯糖醇的产量,研究不同类型表面活性剂对德巴利汉逊酵母(Debaryomyces hansenii)发酵生产D-阿拉伯糖醇的影响。结果表明:阳离子和阴离子表面活性剂对D-阿拉伯糖醇的生成几乎没有影响,部分非离子表面活性剂对D-阿拉伯糖醇的生产有促进作用,其中Trition X-100的影响最为显著。在不同发酵时间加入不同浓度的Trition X-100均对D-阿拉伯糖醇的生产有促进作用,当发酵24 h添加30 g/LTrition X-100时,D-阿拉伯糖醇的产量达到最高(92.9 g/L),相比于对照增加了27.2%。

| Abstract: | To enhance the productivity of D-arabitol,the effects of cationic,anionic and non-ionic surfactants on fermentation production of D-arabitol by Debaryomyces hansenii were investigated.The results showed that the cationic and anionic surfactants had little effect on the fermentation of D-arabitol,while certain non-ionic surfactants could promoted the production of D-arabitol.The non-ionic surfactant Triton X-100 was proved to be the best one.The D-arabitol production was promoted by adding different concentr... |
