a
Ex, samples harvested at the exponential phase; St, samples harvested at the stationary phase. The number after the label stands for the incubation time; labels beginning with “Ae” are for aerobic samples, and those with “An” are for anaerobic samples. For example, An12 represents cells grown in anaerobic medium for 12 h, and Ae24 represents cells grown in aerobic medium for 24 h. Numbers in brackets indicate standard deviations of measurements from 3 biological repeats.
