Growth- and substrate-dependent cdhAp-uidA expression in M. acetivorans. Cultures were grown on methanol (A), shifted from methanol to acetate (B), grown on acetate (C), or grown on CO (D); OD578 (filled symbols) indicates growth; β-glucuronidase activity (open symbols) indicates expression from the specific promoters. Squares, P1016 (cdhA1p-uidA); circles, P3860 (cdhA2p-uidA).
