Levan and inulin are two types of fructan. Levan is composed of β-(2, 6) fructosyl linkage
and inulin is composed of β-(2, 1) linkage. Both levan and inulin have been accepted and …

Highlights•Inulin and inulin-type fructooligosaccharides from plants are prebiotic.•Fructans
with β-2, 6 linkage have a potential as novel and effective prebiotics.•Levansucrases from …

Levan, a unique homopolysaccharide consisting of fructose residues linked by β-(2, 6)
bonds, possess promising physiochemical and physiological properties with numerous …

Nowadays, levan synthesis and its biocatalysis is a step claiming attention due to its
promising uses in biomedical field. Levansucrase, as the enzyme responsible of levan …

A high molecular weight levan was produced by a novel levansucrase and some properties
of this polymer were investigated. The levan exhibited a poroid microstructure as well as …

Levansucrases of Pseudomonas syringae pv. tomato DC3000 (Lsc3) and Pseudomonas
chlororaphis subsp. aurantiaca (also Pseudomonas aurantiaca)(LscA) have 73% identity of …

Levansucrases (EC 2.4. 1.10, LS) are of high interest for the synthesis of novel prebiotic
fructooligosaccharides. Hindered by the limited availability of LS enzymes and a propensity …

This review provides an overview of the current status of the chemistry and biology of di-d-
fructose dianhydrides (DFAs) with a focus on their potential as functional foods. The history …

Di-d-fructose dianhydrides (DFAs) comprise a unique family of stereoisomeric spiro-tricyclic
disaccharides formed upon thermal and/or acidic activation of sucrose-and/or d-fructose-rich …

Levan or high molecular β-2, 6-linked fructose polymer is produced extracellularly from
sucrose-based substrates by bacterial levansucrase. In the present study, to investigate the …
