Abstract

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. Types of biopolymers, are including nucleic acids, proteins, polysaccharides, polyhydroxyalkanoate, polyphenols, and polysulfone. In order to use biopolymers in industry to commercialization the production process and optimize its production, According to studies on optimizing the production of biopolymers is specified In addition to the impact of important nutritional factors in the production process of biopolymers such as sources of carbon, nitrogen, phosphorus, sulfur and physical factors in the production process of biopolymers are highly effective. In this study, parameters such as intensity, aeration, agitation speed, temperature and pH for optimal production of biopolymers have been investigated. According to the results, most references are considered appropriate values for the aeration rate, agitation speed, temperature and pH, respectively 0.5-3 vvm, 200-800 rpm, 27-32°C, 8-5, ‌that under this condition will produce the polysaccharide.
