Abstract

Effect of composition of the medium used for the inoculum cultivation, of the age and amount of the inoculum was investigated using a 3-L glass fermentor with a working volume of 1 L. The highest productivity of the culture was obtained when using a 20% (V/V) 1-d inoculum grown in the MRS medium. Yields of lactic acid were 88-97%, while the L(+)-isomer represented about 80% of the total product.

摘要

使用工作体积为1L的3L玻璃发酵罐，研究了用于接种物培养的培养基组成、接种物的年龄和数量的影响。当使用在MRS培养基中培养的20%（V/V）1天龄接种物时，培养物的生产率最高。乳酸产量为88-97%，而L（+）-异构体约占总产物的80%。
