PHB accumulation profiles of H. seropedicae SmR1 (parental strain) and the NTR system mutants. Strains grew in NFbHP medium amended with 37 mM DL-malate and 20 mM (A) or 5 mM (B) of ammonium chloride at 30 °C (orbital agitation at 120 rpm). The PHB contents were determined in three independent samples. nd – non-detected.
