Screening and Isolation of Bacterial Isolates for Polyhydroxyalkanoates Production from Oil-Contaminated sites
Abstract: Synthetic polymers are generally manufactured from petroleum and chemical-based sources. These polymers are employed in day-to-day life basic needs which leads to the production of huge number of synthetic polymers that accumulate in nature for thousands of years. There are limitations associated with synthetic polymers apart from their non-biodegradability, non-compatibility their mechanical and physical properties that cannot be easily altered narrows their few applications. PHAs (polyhydroxyalkanoates) are biopolymers that can …
