Abstract:l-Malate fermentative rate in Lactobacillus plantarum and Lactobacillus curvatus was improved when l-malate was over 0.1% but decreased when exogenous d-glucose raised over 0.3% or in the presence of exogenous l-lactate. Significant increases in the growth were observed in the presence of exogenous d-glucose. l-malate residual concentrations were in all cases below 1%.
