Description Halophilic microorganisms produce several metabolites having potential application in biotechnology and industry. They
also produce polyhydroxyalkanoates (PHA), which are suitable replacements for conventional plastics for packaging food
and non-food materials due to their biocompatible and biodegradable properties. PHA produced by the native isolate of
Halomonas venusta KT832796 using a minimal medium was made into a film. It was characterized using Fourier Transform
Infrared (FTIR) spectroscopy, Nuclear Magnetic Resonance (NMR) spectroscopy, GC–MS, UTM (Mechanical strength),
Differential Scanning Calorimetry (DSC) and X-ray diffraction (XRD) analysis. Based on FTIR, NMR and GC–MS analyses
the polymer produced by Halomonas venusta KT832796 was found to be poly(3-hydroxybutyrate). The polymer had a
tensile strength of 26 MPa and Young’s modulus of 3 GPa and the melting temperature Tm 173.59 °C, which are found to be
similar to the standard PHB polymer and the crystalline state was revealed by XRD pattern. This PHB polymer can be used
in food packaging systems and medical applications for drug delivery. This is the first communication on characterization
of PHA produced by Halomonas venusta.
