ABSTRACT
Exopolysaccharides (EPS) are excreted by a variety of microorganisms as carbohydrate macromolecules helpful in establishing interaction between host and environment, subsequently impactful in the host to thrive in harsh conditions. Furthermore, EPS, such as dextran, levan, pullulan, curdlan, alternan, etc., exert several beneficial impacts on human health and therefore have great significance in the food and pharmaceutical industries. The in-depth understanding of molecular aspects opens novel avenues to design strategies for metabolic engineering of microbial hosts and biocatalyst engineering, subsequently achieving a higher EPS yield and reduction in production cost.
