Abstract

Natural polysaccharides have received much attention due to the plethora of their applications. Acetobacter sp. MRL 5A (KX082688) produced an alkali soluble exopolysaccharide (20.39 g/L) on sucrose based media during the late log and early stationary phases. The exopolysaccharide was insoluble in water with high moisture-retention ability and produced viscous solutions and gels. The exopolysaccharide contained 40.3% glucose, 34.4% galactose, 22.2% mannose and 3.1% of arabinose monomers revealed by GC. The exopolysaccharide showed emulsifying, flocculating and in-vitro antioxidant activity similar to standard exopolysaccharides like dextran and xanthan. This EPS can be of potential use in food, cosmetic, pharmaceutical and biomedical fields.
