摘　　要：近年来发酵法生产高纯度乳酸因其广泛的应用前景引起广大研究者的兴趣。同时随着生物可降解材料聚乳酸(PLA)的生产量剧增,乳酸生产受到全球的关注。然而乳酸生产成本高严重阻碍了聚乳酸的大规模应用,因此寻求优良的乳酸发酵菌株以及低廉的发酵底物将有利于提高乳酸产量、降低成本。同时乳酸在食品行业也具有广泛的应用,包括防腐剂、酸味剂等,因此乳酸的光学纯度以及菌株的安全性得到更大的重视。论述了目前生产乳酸的菌种以及乳酸生产菌利用木质纤维素的研究进展。Fermentative production of optically pure lactic acid has roused interest among researchers in recent years due to its high potential for applications in a wide range of fields. More specifically, the sharp increase in manufacturing of biodegradable polylactic acid （PLA） materials has significantly increased the global interest in lactic acid production. However, higher production costs have hindered the large-scale application of PLA because of the high price of lactic acid. Therefore, exploring excellent lactic acid producer and utilization of inexpensive substrates can deduce cost of lactic acid production and improve the yield of lactic acid. At the same time, lactic acid is widely used in the food industry, including preservatives, sour agent, etc. Discuss recent advance of the kinds of lactic acid producer and consuming lignocellulose-defived sugars.
