Bioplastics are biomass based biodegradable plastics which can be derived from corn starch, pea starch, vegetable fats and oils as well as microorganism like bacteria, algae etc. They may be used for packaging purposes and catering items like bowls, pots, straws, cutlery etc., for making bottles for soft drinks, bags, trays etc. plastics is one of the major pollutant at present time in the world, which is used for daily use like packaging materials, carry bags, well as to reduce the increasing environmental pollution an alternative must developed. This need of plastic can be fulfilled by the use of bioplastics. Polyhydroxyalkanoate are produced by bacteria among which Polyhydroxybutyrate (PHB) is one major group. The property of PHB is similar to synthetic plastics. So, it can be used as a suitable alternative to the present day conventional practices for sustainability. Several bacterial species like Actinobacillus, Azotobacter, Agrobacterium, Rhodobacter and Sphaerotilius have been under focus for their ability of converting organic waste to bacterial PHA. For industrial production of PHB, with some bacterial species like Bacillus spp, Pseudomonas spp, Aeromonas spp, Cupriavidus spp have been extensively used for their potential to produce PHB. Since the production of bioplastic is expensive many techniques adopted for large scale production. But, to obtain PHB in larger amount the selection of proper strain of bacteria, capable of producing or accumulating PHB in less costly way has become an absolute necessity. So in this study, isolating, selecting and screening of an efficient Polyhydroxybutyrate producing microorganism has been done with comparison of the production of PHB (Bio-plastic) in agro industrial waste to find out which one has the potency to produce more PHB.
