Due to the increasing amount of plastic waste and the resulting environmental problems, researchers have long sought to replace oil-based plastics with bioplastics. One of the most important materials is polyhydroxyalkanoate polymer, which is often produced by different bacteria and its suitable properties have made this polymer useful in various fields in addition to the production of bioplastics. In this research, polyhydroxyalkanoate is produced using Vibrio bacteria. After the production stage, the polymer is extracted using SDS and chloroform and in the end the production efficiency using this method in Vibrio bacteria was about 30%. XRD and FTIR were used to examine the polymer and both methods showed the similarity of the polymer extracted from Vibrio in this study and the standard polyhydroxyalkanoate.. The antioxidant properties of the polymer were also investigated in this study. Finally, it can be concluded that Vibrio bacteria has an acceptable efficiency for the production of polyhydroxyalkanoate, and considering the advantages of this bacteria, it can be used to produce the said polymer more easily and cheaper.
