ABSTRACT Fermentation strategies for the production of poly(3-hydroxybutyrate) (PHB) from whey by recombinantEscherichia coli strain CGSC 4401 harboring theAlcaligenes latus polyhydroxyalkanoate (PHA) biosynthesis genes were developed. The pH-stat fed-batch cultures of E. coli CGSC 4401 harboring pJC4, a stable plasmid containing theA. latus PHA biosynthesis genes, were carried out with a concentrated whey solution containing 280 g of lactose equivalent per liter. Final cell and PHB concentrations of 119.5 and 96.2 g/liter, respectively, were obtained in 37.5 h, which resulted in PHB productivity of 2.57 g/liter/h.
