(A) Organization of genes in P. umsongensis GO16 that encode enzymes that enable growth with EG and TA when used as a sole source of carbon and energy. (B) Biomass (CDW g l⁻¹) when P. umsongensis GO16 was grown with EG, TA and growth of P. putida KT2440 pBT’T_tph, KT2440 expressing whole tph operon including the native regulator from P. umsongensis GO16 grown with TA. tphA‐K represents KT2440 expressing the tph operon without the native regulator and this strain was grown with TA, p‐hydroxybenzoate (pOHB) or a mixture of both substrates. tphR‐B represents the growth of KT2440 expressing the tph operon without the transporter tphK grown with TA, pOHB or a mixture of both. The values represent the average of three independent biological replicates and correspond to the biomass accumulated in 48 h.
