Growth curves of strain B356 on diphenylmethane when the inocula were prepared by growing the cells on either diphenylmethane (DPM/DPM), biphenyl (BP/DPM), or sodium acetate (NaAcetate/DPM) (A) or on biphenyl when the inocula were prepared by growing the cells on either biphenyl (BP/BP), diphenylmethane (DPM/BP), or sodium acetate (NaAcetate/BP) (B). A growth curve also was obtained for cells pregrown on diphenylmethane and then grown on diphenylmethane plus 3-chlorobenzoate (DPM/DPM+3CBA) or cells pregrown on biphenyl and then grown on biphenyl plus 3-chlorobenzoate (BP+3CBA). The growth curves were obtained using a Bioscreen C system as described in Materials and Methods.
