چکیده

The polysaccharide levan was synthesized in a solidified agar medium containing sucrose as a source of fructose. The biosynthesis was achieved by the enzyme levansucrase (2,6-fructan-d-glucose 6-fructosyltransferase, EC 2.4.1.10), a small quantity of which was placed in circular wells cut in the agar gel. The enzyme slowly diffused through the agar-sucrose medium and the synthesis of levan was observed as circular white areas, the size of which was dependent on the time of incubation and the concentration of enzyme used.

Box-Wilson Design for Optimization of in vitro Levan Production and Levan Application as Antioxidant and Antibacterial Agents

Background: Levan or fructan, a polysaccharide of fructose, is widely used in various commercial industries. Levan could be produced by many organisms, including plants and bacteria. The cloning of the gene from Bacillus licheniformis, which expressed levansucrase in E. coli host, was carried out successfully.  In the present study, we performed the in vitro production of levan and analyzed its...

High-throughput assay of levansucrase variants in search of feasible catalysts for the synthesis of fructooligosaccharides and levan.

Bacterial levansucrases polymerize fructose residues of sucrose to β-2,6 linked fructans-fructooligosaccharides (FOS) and levan. While β-2,1-linked FOS are widely recognized as prebiotics, the health-related effects of β-2,6 linked FOS are scarcely studied as they are not commercially available. Levansucrase Lsc3 (Lsc-3) of Pseudomonas syringae pv. tomato has very high catalytic activity and st...

Influence of fermentation conditions on levan production by Zymomonas mobilis CT2

Zymomonas mobilis produces two extracellular sucrases namely levansucrase (sac B) and sucrase (sac C). A mutant strain of Z. mobilis CT2 defective in sucrase sac C, constructed earlier by gene disruption, produced higher levels of levan (27.2 g L) than the parent strain B14023 (15.4 g L) from 200 g L of sucrose at 25°C and pH 5.0. Increasing fermentation temperature from 25 to 35°C enhanced eth...

Characterization and mutational analysis of three allelic lsc genes encoding levansucrase in Pseudomonas syringae.

In the plant pathogen Pseudomonas syringae pv. glycinea PG4180 and other bacterial species, synthesis of the exopolysaccharide levan is catalyzed by the extracellular enzyme levansucrase. The results of Southern blotting and PCR analysis indicated the presence of three levansucrase-encoding genes in strain PG4180: lscA, lscB, and lscC. In this study, lscB and lscC were cloned from a genomic lib...

Biochemical and molecular characterization of a levansucrase from Lactobacillus reuteri.

Lactobacillus reuteri strain 121 employs a fructosyltransferase (FTF) to synthesize a fructose polymer [a fructan of the levan type, with beta(2-->6) linkages] from sucrose or raffinose. Purification of this FTF (a levansucrase), and identification of peptide amino acid sequences, allowed isolation of the first Lactobacillus levansucrase gene (lev), encoding a protein (Lev) consisting of 804 am...
