解淀粉乳酸细菌在L-乳酸发酵生产中的应用

对解淀粉乳酸细菌及其产生的淀粉酶和发酵工艺等方面的国内外研究现状进行了综述。解淀粉乳酸细菌具有分泌淀粉酶的能力，可免去原料水解处理工序直接发酵淀粉质原料生产乳酸，可以简化生产工艺，并可节约设备投资，进而降低生产成本。解淀粉乳酸细菌主要分离自传统发酵食品，也可从有机废弃物和厨余垃圾中分离得到。介绍了解淀粉乳酸细菌直接利用淀粉质原料的机理，比较了解淀粉乳酸菌发酵生产L-乳酸的工艺。提出通过诱变育种和基因工程育种等方法获得更加高效的解淀粉乳酸细菌，并结合先进的发酵、分离技术来提高乳酸生产效率。

Application of Amylolytic Lactic Acid Bacterial in Production of L-lactic Acid by Fermentation

Abstract To summarize the present situation of research on amylolytic lactic acid bacteria and its amylase,and the fermentation technology of amylolytic lactic acid bacteria.The amylolytic lactic acid bacteria have the ability of secreting amylase,can direct ferment starchy material into lactic acid without hydrolysising processes, simplify the production process, and saving the equipment investment, thereby, decrease the cost of production. Amylolytic lactic acid bacteria isolated from traditional fermented food, or from organic waste and kitchen waste.The mechanism of direct utilize starch raw materials by the amylolytic lactic acid bacteria were introduced, the fermentation technology of amylolytic lactic acid bacteria were compared. Meanwhile it was pointed out that through mutation breeding and genetic engineering methods gain the potent amylolytic lactic acid bacteria,and use the advanced fermentation and separation technology can improve the productivity of lactic acid.
