Induction of the kduD and kduI promoter in E. coli MG1655 by mouse diets, carbohydrates, casaminoacids, or hexuronates under aerobic and anaerobic growth conditions.

aRelative luminescence data for E. coli MG1655 carrying pkduDp::luxAB or pkduIp::luxAB are shown. For both aerobic and anaerobic growth conditions, luciferase activity was normalized to values determined for cells grown on glucose (50 mM). Data are expressed as medians and 25% and 75% percentile (aerobic, n = 5–7; anaerobic, n = 4–7).bCultures were grown on M9 minimal medium containing pulverized mouse diets or dietary components under aerobic or anaerobic conditions and shaken at 220 and 120 rpm, respectively, at 37°C for 16 h.c,dKruskal-Wallis one-way analysis of variance and Dunn’s multiple-comparison test were used for calculations. c, Pd, Pe, P
