Microbial exopolysaccharides are the polysaccharides that are produced outside the cell wall by many microorganisms. Some are well-established biotechnological products that are manufactured commercially from renewable resources to provide biodegradable alternatives to traditional plant and algal gums. Others have potentially useful physical or chemical properties, while a few possess valuable biological properties.
