CDW: cell dry weight; PHA: polyhydroxyalkanoate; PHB: poly(3-hydroxybutyrate); PHBV: poly(3-hydroxybutyrate-co-hydroxyvalerate); n.d.: not determined. ^aIncubated at 37°C in PHA accumulation medium supplemented with starch or glucose. ^bCells were harvested at the early stationary phase for each strain. ^cPHA content in dried cells was determined using gas chromatography.
