Selective hydrogenation of citral to geraniol using Rhodotorula mucilaginosa CCZU-G5
摘要
Abstract
Biological conversion of citral to geraniol was studied using Rhodotorula mucilaginosa CCZU-G5 as fermentation strain. The effects of culture time,co-substrate concentration,initial substrate concentration,cell quantity and the reaction time on selective hydrogenation of citral to geraniol were investigated to determine the optimal fermentation conditions. The results showed that after 28 h culturing,yeast cells reached the end of the logarithmic growth phase,in which the quantity and activity of the cells were at a high level. In the process of biological conversion,the optimal fermentation conditions were as follows:glucose concentration 40 g/L,initial citral concentration 4 g/L,yeast cell concentration 0.4 g/mL and reaction time 22 h. Under these conditions,citral conversion and geraniol selectivity reached 88.6% and 95.2%,respectively. The study lays the foundation for commercialized biosynthesis of geraniol.关键词
