Exploiting metagenomic diversity for novel polyhydroxyalkanoate synthases: Production of a terpolymer poly(3-hydroxybutyrate-co-3-hydroxyhexanoate-co-3-hydroxyoctanoate) with a recombinant Pseudomonas putida strain

► Hydrocarbon contaminated metagenomic library for screening novel PHA synthases. ► Novel PHA synthase expression results in a terpolymer P(3HB-co-3HHx-co-3HO)]. ► The terpolymer contains 21% mcl-monomers with improved properties.
