Preparation of glycolic acid by the fermentation of ethylene glycol
摘要
Abstract
In this paper the fermentation process of glycolic acid from ethylene glycol by Gluconobacter oxydans is studied.The results showed that the optimal fermentation condition was as follows：the ethylene glycol concentration was 80 g/L,adding 40 g/L of sorbitol to the medium as supplement carbon source in order to promote cell growth,1.0mol/L of sodium hydroxide and ammonia mixture was the neutralizer used in the fermentation process to maintain pH of 5.5.After 40hrs fermentation,the production of glycolic acid was 97.4 g/L,the yield was 96.8%.The method established the foundation for the biological production of glycolic acid.关键词
