Beschreibung

General description

Levan is a polysaccharide produced by some microorganisms and plants. It is a non-typical biopolymer composed of fructose units[1] linked by β-(2→6).[2] Levan is an exopolysaccharide (synthesized outside the cell).[1]

Application

Levan from Erwinia herbicola has been used as a:

• standard for the nuclear magnetic resonance (NMR) spectroscopy analysis of levan produced by Bacillus licheniformis NS032 in sugar beet molasses-based medium[2]
• polysaccharide substrate to test the ability of Prevotella copri isolates to grow when polysaccharides were provided as the sole carbon source in vitro[3]
• substrate in levanase activity assay[4]

Biochem/physiol Actions

Levan has various industrial applications like cosmetics, medicine, or nanotechnology.[1] It might exhibit anti-hyperglycemic effect and anti-tumor action, prevent diabetes-induced oxidative stress and increase catalase (CAT) and superoxide dismutase (SOD) in the heart. Levan is also recognized for its immunomodulating and prebiotic actions.[2]
