Fig. 4From: Application of whole-cell biosensors for analysis and improvement of L- and D-lactic acid fermentation by Lactobacillus spp. from the waste of glucose syrup productionGrowth and lactic acid concentrations obtained with (a, d) L. paracasei, (b, e) L. amylovorus, and (c, f) L. lactis in ORRF-MM with supplements. The medium contained 200 g/L ORRF including approximately 42 g/L (230.9 mM) of glucose. Lactic acid concentrations are determined at 72 h using BLA1 and BLA2. Substrates’ compositions are indicated. Error bars represent standard deviations of three biological replicates, *p < 0.05 (unpaired t-test)Back to article page
