The Halophilic Bacterium Paracoccus haeundaensis for the Production of Poly(3-Hydroxybutyrate-co-3-Hydroxyvalerate) from Single Carbon Sources.

ABSTRACT: The study objective was to evaluate the potential production of polyhydroxyalkanoates (PHAs), a biodegradable plastic material, by Paracoccus haeundaensis for which PHA production has never been reported. To identify the most effective nitrogen-limited culture conditions for PHAs production from this bacterium, batch fermentation using glucose concentrations ranging from 4 g l^-1 to 20 g l^-1 with a fixed ammonium concentration of 0.5 g l^-1 was carried out at 30°C and pH 8.0. A glucose supplement of 12 g l^-1 produced the highest PHA concentration (1.6 g l^-1) and PHA content (0.63 g g^-1) thereby identifying the optimal condition for PHA production from this bacterium. Gas chromatography-mass spectrometry analysis suggest
