Characterization of antioxidant activity of exopolysaccharides from endophytic Lysinibacillus sphaericus Ya6 under osmotic stress conditions

[Display omitted] •The exopolysaccharide (EPS) was homogenous with molecular weight of 89.62 kDa.•The EPS from L. sphaericus Ya6 was composed of mannose and a small amount of glucose.•Under osmotic stress, scavenging activity of EPS on DPPH radical was enhanced.•All EPS samples had scavenging activi...
