摘　　要：乳酸在化工、医药和食品加工等领域有着广泛的用途。随着聚乳酸产业的兴起，对聚合级L-乳酸的需求量也不断增加。开发低成本的非粮生物质乳酸发酵工艺、实现发酵．分离耦合是降低聚合级L-乳酸成本、摆脱原料价格不断上涨压力的技术趋势。文中简要综述了近2～3年使用非粮生物质发酵生产聚合级L-乳酸的技术进展，并对未来乳酸发酵工艺作了展望。Lactic acid has a wide range of uses in the chemical, pharmaceutical and food industry. With rapid development of poly （lactic acid） industry, the demand for polymer-grade L-lactic acid is continuously increasing. Developing low-cost, non-food-biomass-lactic-acid fermentation process and the fermentation-separation coupled technology are trends to reduce polymer-grade L-lactic acid production cost. This review summarized the most recent advances in low-cost L-lactic acid fermentation based on the use of non-food biomass, followed by addressing the key issue that might be strategically important for future development of polymer-grade L-lactic acid production in industry.
