Abstract
ABSTRACT
Medium-chain-length (mcl)-polyhydroxyalkanoates (PHAs), elastomeric polyesters synthesized by Genus Pseudomonas bacteria, generally have many different monomer components. In this study, PHAs biosynthesized by four type strains of Pseudomonas (P. putida, P. citronellolis, P. oleovorans, and P. pseudoalcaligenes) and a typical PHA producer (P. putida KT2440) were characterized in terms of the monomer structure and composition by gas chromatography-mass spectrometry (GC-MS) analysis. With a thiomethyl pretreatment of PHA methanolysis derivatives, two unsaturated monomers, 3-hydroxy-5-dodecenoate (3H5DD) and 3-hydroxy-5-tetradecenoate (3H5TD), were identified in mcl-PHAs produced by P. putida and P. citronellolis. The quantitative analysis of PHA monomers was performed by employing GC-MS with methanolysis derivatives, and the results coincided with those obtained by performing nuclear magnetic resonance spectroscopy. Only poly(3-hydroxybutyrate) was detected from the P. oleovorans and P. pseudoalcaligenes type strains. These analytical results would be useful as a reference standard for phenotyping of new PHA-producing bacteria.

Abstract
Polyhydroxyalkanoates (PHAs) are commercially-valuable biocompatible and biodegradable polymers with many potential medical, pharmaceutical and other industrial applications. The analysis of PHA monomeric composition is especially challenging due to the broad chemical diversity of PHA monomers and lack of analytical standards to represent the chemically-diverse PHA monomer constituents. In this study, a novel strategy based on on-line liquid chromatography-mass spectrometry (LC-MS) and off-line liquid chromatography-nuclear magnetic resonance (LC-NMR) was established to quantify seven PHA monomers with available standards and used to elucidate the structures of unknown PHA monomers. The strategy was successfully applied for the determination of monomeric composition in bacterial PHAs isolated from Pseudomonads cultivated on different carbon sources after hydrolysis. The results of this work demonstrated that the newly-developed strategy was efficient, repeatable, and could have good potential to be employed for detailed analysis of PHA monomeric composition.
