Growth curves and d-lactate production of corresponding strains. ac Under normal conditions. df Under extra nitrogen and phosphate supplemented conditions. Syn2973-LdhOmcS-1NP: the strain Syn2973-LdhOmcS grew in the common BG11 medium, Syn2973-LdhOmcS-2NP-8NP: the strain Syn2973-LdhOmcS grew in BG11 medium with twofold to eightfold concentration of nitrate and phosphate, Syn2973-LdhOmcS-2 N-8 N: the strain Syn2973-LdhOmcS grew in BG11 medium with twofold to eightfold concentration of nitrate. Values are average of three independent measurements; Error bars indicate the standard deviation (SD); if error bars are invisible, they are small than the data point symbol
