A new approach at the transcriptional level was applied to lactate-based polyester production. Four sigma factor disruptants, Delta rpoN, Delta rpoS, Delta fliA and Delta fecl, of Escherichia con were used as hosts for poly(lactate-co-3-hydroxybutyrate) production from glucose. Among them, Delta rpoN caused dual positive effects of polymer production, enhanced cellular content and lactate fraction.
