Relative maximal growth rate. The relative growth rate is expressed as the average of the three growth determinations ± standard deviation. a: strain BJ-STC-a; a-ToqxRwt: strain BJ-STC-a complemented with the wild type oqxR gene; b: strain BJ-STC-b; b-TpstSwt: strain BJ-STC-b complemented with the wild type pstS gene; b-MFOX: BJ-STC-b mutant selected with cefoxitin; b-MFOX-TphoRwt: BJ-STC-b mutant selected with cefoxitin and complemented with the wild type phoR gene; b-METP: strain BJ-STC-b mutant selected with ertapenem; b-METP-TphoBwt: strain BJ-STC-b mutant selected with ertapenem and complemented with the wild type phoB gene; b-MIMP: BJ-STC-b mutant selected with imipenem; b-MIMP-TphoBwt: BJ-STC-b mutant selected with imipenem and complemented with the wild type phoB gene; c: strain BJ-STC-c; c-TphoUwt: strain BJ-STC-c complemented with the wild type phoU gene.
