Evaluation of improved biological properties of chemically modified exopolysaccharides from Lactobacillus plantarum BR2.

ABSTRACT: This work engrosses the production and further chemical modifications of EPS produced by Lactobacillus plantarum BR2 and subsequent evaluation of their biological properties showed greater antioxidant properties for the derivatives compared to its native unmodified form. Of the three derivatives, acetylated EPS (a-EPS), carboxymethylated EPS (Cm-EPS), and sulphated EPS (s-EPS), a-EPS exhibited the highest DPPH radical scavenging and total antioxidant activity in a dose-dependent manner. At all tested concentrations, a-EPS showed higher scavenging activity, and a maximum activity of 73.81% at 2 mg/mL. Meanwhile, s-EPS showed the highest reducing power potential and hydroxyl radical scavenging activities. At 2 mg/mL concentration, the order of reducing power was observed to be s-EPS (
