Lactobacillus delbrueckii was grown on sugarcane molasses, sugarcane juice and sugar beet juice in batch fermentation at pH 6 and at 40 degrees C. After 72 h, the lactic acid from 13% (w/v) sugarcane molasses (119 g total sugar l(-1)) and sugarcane juice (133 g total sugar l(-1)) was 107 g l(-1) and 120 g l(-1), respectively. With 10% (w/v) sugar beet juice (105 g total sugar l(-1)), 84 g lactic acid l(-1) was produced. The optical purities of D: -lactic acid from the feedstocks ranged from 97.2 to 98.3%.
德氏乳杆菌在pH值为6、温度为40℃的条件下，以甘蔗 molasses、甘蔗汁和甜菜汁为原料进行分批发酵。72小时后，13%（w/v）甘蔗 molasses（总糖含量119 g l⁻¹）和甘蔗汁（总糖含量133 g l⁻¹）产生的乳酸分别为107 g l⁻¹和120 g l⁻¹。以10%（w/v）甜菜汁（总糖含量105 g l⁻¹）为原料时，产生了84 g l⁻¹的乳酸。原料中D - 乳酸的光学纯度在97.2%至98.3%之间。
