Abstract
Erythritol production by an osmophilic mutant of Candida magnoliae was performed in fermentations of up 50 l to develop an optimized commercial process. By simultaneous feeding glucose and yeast extract, erythritol productivity of 1.2 g l(-1) h(-1) was reached giving 200 g erythritol l(-1) with a yield of 0.43 g g(-1).
摘要
利用大丽花假丝酵母的嗜渗突变体生产赤藓糖醇的过程在高达50升的发酵中进行，以开发一种优化的商业工艺。通过同时添加葡萄糖和酵母提取物，赤藓糖醇生产率达到1.2克/升·小时，产量为200克/升，产率为0.43克/克。
