Promoter activity of mleR and mleS in the absence of malate. Promoter activity of mleR and mleS during batch cultivation in BMS medium without malate under anaerobic conditions. A: Optical density and luciferase activity of both promoters in the wildtype background. B: Optical density and luciferase activity of both promoters in the ΔmleR background. Grey square, Optical density of strains carrying mleRp-luc; Black circle, Optical density of strains carrying mleSp-luc; Open square, RLU of strains carrying mleRp-luc; Open circle, RLU of strains carrying mleSp-luc
