Abstract
Lactobacillus delbrueckii was grown on sugarcane molasses, sugarcane juice and sugar beet juice in batch fermentation at pH 6 and at 40°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%.
