Growth of ACN2069 in continuous chemostat culture: OD (dark green circle), benzoate (brown diamond), 4-hydroxybenzoate (blue up pointing triangle), glucose (yellow circle), xylose (light green square), and arabinose (pink down pointing triangle). The feed concentrations (each) of glucose, xylose, and arabinose were maintained at nominally 10 mM, and the concentrations of benzoate (brown straight line) and 4-hydroxybenzoate (blue dashed lines) were step-changed approximately every 24 h as described in “Materials and methods”
