Plastic pollution is the buildup of plastic debris in the environment that negatively impacts people, wildlife, and their habitat. Plastic items are not biodegradable and they are still present in the environment. Bioplastics which are biodegradable plastics are emerging to solve the problem of plastic accumulation. Polyhydroxybutyrate or PHB is a bioplastic that serves as an alternative to synthetic plastics. PHB is a lipid reserve material that gets accumulated within the cell wall of micro organisms under stress conditions. In the current work, marine medium with a 15% high salt concentration was used to isolate halophiles. From the marine sample taken at Mumbai's Juhu beach, with using different selective medias such as Marine agar, Nutrient agar, Halophilic medium agar, Horikoshi agar and dunda’s agar. During these no colony was observed on dunda’s agar. 13 isolates were discovered among them from 11 isolates was showing PHB Positives. In this study isolated strain MA1 Showing highest PHB production according to its spectrophotometric analysis of quantification. An isolated strain was morphological and biochemical characterized.
