【摘要】 考察了多种发酵常见微生物对单糖的利用差异(尤其是葡萄糖/果糖利用差异)。并在分子生物学层面,从转运和磷酸化两个角度分析了造成这种差异的原因。通过定位与此相关的特殊操纵子或编码基因,能够帮助实现工业微生物的改造,从而使多种非葡萄糖基生物质能源得到有效利用,对能源模式的转化和可持续发展有着重要意义。更多还原

【Abstract】 Different mechanisms in utilization of various monosaccharides by microorganism(especially G/F discrepancy)were studied.Transportation and phosphorylation are considered to be key factors of this discrepancy.By locating relative genes or operons,genetic modification of industrial microbe could be performed to help further develop multiple biomass energy resource with un-glucosyl group,which is very meaningful to the transformation of energy pattern as well as sustainable development.更多还原
