In vitro antioxidant activity of levan produced by Brachybacterium sp. CH-KOV3

Abstract

In this work levan isolated from microorganism Brachybacterium paraconglorneraium and fragments obtained by partial hydrolysis of purified polysacharide were evaluated by antioxidant activity. Levans (fructans) are generally linear polysaccharides containing fructose residues linked predominantly by beta-(2,6)-glyeosidic bonds and one alpha-glucose at the end of the chain. Vlith branching through the position of C1. The aim of the presented work was investigation and comparison of antioxidant potential of fructan synthesized by the non-pathogenic, rod shaped, Gram-positive Brachrhocierilem sp. CH -KOV3 and fragments obtained by its controlled acid hydrolysis.
