Abstract: An exopolysaccharide (EPS) in the amount of 250 mg/l was obtained from the culture supernatant of Lactobacillus plantarum EB-2 grown in MRS broth. In the IR spectrum of EPS, intense absorption bands were found, generally characteristic of a class of carbohydrates. The molecular weight of the EPS obtained from L.plantarum EB-2 was 3.16x104 Da, the polydispersity index was 1.9. The EPS from L.plantarum EB-2 consisted from a mannose, glucose, galactose and rhamnose in an molare ratio of 21.7:12.4:2:1, respectively. An in vitro study of the antioxidant activity of L.plantarum EB-2 EPS in the diphenylpicrylhydrazil (DPPH) system showed that radical scavenging activity (RSA) has being increased depending on the concentration of the investigated EPS. The maximum RSA was detected at 4 mg/ml being 42%, which is more than the activity of ascorbic acid.

Key words: lactobacilli, exopolysaccharide, monosaccharide composition, antioxidant.
