Relationship of rPA activity and PHB accumulation. (A) rPA gene expression was induced at the early exponential growth phase (4 h). (B) rPA gene expression was induced at the midexponential growth phase (8 h). (C) rPA gene expression was induced at the late exponential growth phase (12 h). E. coli XL1-Blue (pHBS01/pSPAr) was grown in LB medium plus 0.5% glucose and induced at indicated time points. After induction, the cells were cultivated for a further 10 h. rPA activity was expressed as IU per gram of cell dry weight (IU/g cdw).
