Biopolymers are biological macromolecules that large and small subunits that bind covalently to the same are connected by a long chain of cause and they are built. Because of the biopolymers are produced naturally of the living organisms such as plants, animals and microorganisms therefor are biodegradable, they are very good. biopolymers have been developed in various forms, therefor have capacity to use in various industries. In order to use biopolymers in industry to commercialization the production process and optimize its production. Regard to the main role a well bioreactor, providing a controlled environment in order to achieve optimal conditions for growth or production type of Bioreactor also affects the production of biopolymers. In this study, an overview of the biopolymers and various bioreactor and have been investigated suitable bioreactor for the production of microbial biopolymers.
