Comparative analysis of glycerol consumption and molar growth yield on glycerol for the wild type and the ΔvapBC mutant. (A) Supernatant samples and dry weights were taken for strain mc2155 (wild type) and the ΔvapBC deletion mutant at two time points during the early stages of growth (T1 and T2). (B) Specific rate of glycerol consumption (mmol glycerol consumed/h/g [dry weight] cells). (C) Molar growth yield on glycerol (Yglycerol) (g [dry weight] cells/mol glycerol utilized) was calculated for each strain. The glycerol consumption rate and Yglycerol were determined for three replicate samples, and the error bars represent standard deviations.
