PHA occurs naturally in microorganisms when amount of nutrient in environment is low and carbon source is high. Known strain P.phragmitetus ERC-8 was used for PHA production in Bushnell haas (BH) medium (pH 7.0) with 3% glycerol. After incubation period, to extract out the PHA from biomass solvent extraction method was used. The amount of extracted PHA was 0.1205 g/L. Extracted PHA has the low processability, to improve the processability of PHA was blended with other synthetic bio-degradable polymer such as PLA and naturally occurring polymers like gelatin, agar and starch. Instrumental analysis, such s FTIR and NMR was used for the characterization of PHA and copolymers of PHA. Thermal analysis was used for determination of melting temperature and degradation temperature of PHA and copolymer of PHA. Copolymer of PHA showed the higher melting temperature then pure PHA. By incorporating the PLA into the PHA polymer can increases the processability of PHA polymer. Copolymers with higher melting temperature and higher processability are produced by copolymerization.
