Polyhydroxyalkanoates (PHAs) are biodegradable and environmentally friendly bioplastics accumulate as storage materials by various bacteria. These PHAs serve as energy and carbon reserve materials for the bacteria. PHAs can be completely degraded within a span of 12-14 months by microbial consortia into CO2 and water. Wood waste as a carbon source for the isolation and screening of polyhydroxyalkanoates (PHAs) accumulating bacteria was endeavored during our study. Bacterial strains collected from various environmental sources were subjected to culture studies for PHA synthesis.  Pseudomonas lignicola was the single strain which was able to synthesize PHA using the carbon source derived from wood waste, when compared to other bacterial strains.
