根霉菌利用木质纤维素发酵生产有机酸的研究进展*

木质纤维素是世界上储量最丰富、最廉价的可再生生物质资源，利用木质纤维素发酵生产有机酸具有重大的经济效益及社会效益。为发掘影响木质纤维素利用的关键因素，对根霉菌的木糖代谢途径以及利用木质纤维素发酵生产乳酸、富马酸等重要有机酸的生产方式、发酵策略等进行了阐述，指出针对木糖的转化率是制约木质纤维素高效利用的瓶颈。

Production of Organic Acid from Lignocellulosic Materials by Rhizopus sp.

The bioconversion of lignocellulosic materials for organic acid had great meaning to both economic and social benefit, owning to its renewable character, abundance and low price.In order to find out the key to the efficient utilization of lignocellulose,kinds of fermentation strategies to product organic acid (such as loctic acid,funaric acid)from lignocellulcsic were discussed,also the xylose metabolic pathway of Rhizopus sp.was extensively reviewed,and it find out that the low conversion of xylose was the bottle-block.
