^aCell-counting techniques included CFU, phase-contrast (PC), brightly fluorescing cells stained with RedoxSensor Green (B_RG), dimly fluorescing cells stained with RedoxSensor Green (D_RG), and cells indicating a living status (Live) under conditions of Live/Dead staining. All measurements were performed concurrently with oxygen consumption measurement on the days indicated for K-12 replicate cultures.
