【摘要】 探讨了有机废物乳酸发酵的影响因素,包括菌种、营养物质、产物抑制、氧气和发酵方式,概述了利用含碳水化合物的有机废弃物和厨房垃圾生产乳酸的现状,并对未来的研究方向提出了展望。指出在厌氧条件下应用同型发酵乳酸细菌,采用原位产物分离技术和细胞再循环发酵通常会提高乳酸的产量;采取多菌种的联合发酵并优化提取工艺,将有助于实现有机废物工业化生产乳酸。更多还原

【Abstract】 The fermentative production of lactic acid (LA) with organic wastes is one of the effective solutions in wastes recycling.Several factors affecting the fermentative LA production with lactic acid bacteria (LAB) were discussed,including microorganism, nutrient substrate,end-product inhibition,and oxygen.Furthermore, the status quo of the production of lactic acid with starchy and cellulosic and kitchen wastes was summarized and the tendencies of future research and development were indicated . Meanwhile it was pointed out that with homofermentative LAB, recirculation of cells and in situ production removal (IS-PR) technology under anaerobic condition,LA yield could be increased and co-inoculation of various LAB with the optimizing LA separation technique could help to the industrialization of LA production with organic wastes.更多还原
