The handbook of microbial bioresources.

Book cover for The handbook of microbial bioresources.


This book, inclusive of 39 chapters, provides a detailed discussion on the biotechnological methods and processes, as well as the industrial applications, of various microbial resources. Current use of these microbial resources in the medical (anti-cancer substances from bacteria), agricultural (i.e., mycorrhizal fungi, biofertilizers, insect pest control), food (i.e., probiotics, prebiotics), fee...

Exopolysaccharide (EPS)-producing bacteria: an ideal source of biopolymers.

Polysaccharides are the most abundant carbon sources in the biosphere, thus it is no surprise that their uses and applications are wide ranging. Extended use of polysaccharides has initiated a need to focus research on the isolation of polysaccharides from natural resources. Among the natural resources used for polysaccharide isolation interest has focused on bacterial extracellular polysaccharides as they are candidates for many commercial applications in different industrial sectors such as food, petroleum, cosmetics and pharmaceuticals. These polysaccharides have enabled the industry to replace the traditionally used gums from plants and algae due to the possibility of easy and quick mass production. Bacterial polysaccharides are eco-friendly in nature and are susceptible to natural biodegradation causing little damage to the environment and thus diminishing pollution. These polysaccharides are also not vulnerable to changes in climate and geographical barriers. Thus this chapter encompasses the various sources for isolating exopolysaccharides (EPS) producers, screening methods used for their isolation, polysaccharide recovery, quantification and purification methods.
