Ammonium production in AZBB163 grown in B/MoFeS medium with varied concentrations of sucrose. Shown are the ammonium production (top) and OD600 (bottom) results from growing AZBB163 in B/MoFeS medium (Burk’s medium supplemented with increased cofactor-related elements) with varied sucrose concentrations, with the standard concentration of sucrose (20 g/L) indicated with an (*). Cultures were grown at 26 °C and shaken at 180 rpm, and were grown as 60 mL cultures in 125 mL Erlenmeyer flasks. Bottom graph optical density plotted on a log2-based scale (y-axis). Data points indicate averages, while error bars represent standard deviation (N = 4)
