木聚糖生物转化药物、能源和化工中间体

Bioconversion of xylan for drugs,energy and chemical intermediates

介绍了木聚糖的结构与酶糖化机理,综述了国内外对木聚糖生物转化方面的研究。详细介绍了木聚糖转化为低聚木糖和木糖醇等医药食品、燃料乙醇和2,3-丁二醇等能源物质、乳酸和糠醛等化工中间体的研究进展。

Xylan, the second most abundant polysaccharide compared to cellulose, is a kind of polysaccharide widely existing in the nature. It has tremendous potential applications in many fields, especially in the pharmaceutical, energy and chemicals. Bioconversion with advantages of non-polluting and low-energy consumption expands the applications of xylan. The structure of xylan and its mechanism of enzymatic lycosylation are introduced. The research on bioconversion of xylan into drugs （ xylo-oligosaccharides and xylitol ）, energy （ fuel ethanol and 2,3-butanediol ）, and chemical intermediates （lactic acid and furfural） are described in detail. Enzymatic species, bacteria, zymotic factors and detective methods are comparably studied as well.
