Decoding the Capability of Lactobacillus plantarum W1 Isolated from Soybean Whey in Producing an Exopolysaccharide.

ABSTRACT: This study aims at producing exopolysaccharides (EPS) from a lactic acid bacterial strain. The soybean whey-isolated Lactobacillus plantarum W1 (EPS-W1), which belongs to genus Lactobacillus, is identified using the phenylalanyl-tRNA sequencing method. Of all the examined strains, R-49778 (as numbered by BCCM/LMG Bacteria Collection, Ghent University, Belgium) showed the highest capability of producing exopolysaccharides. Structural characterization revealed a novel exopolysaccharide consisting of repeating units of ?6)-d-Glcp-(1?; ?3)-d-Manp-(1?; ?3)-d-Glcp-(1? and a branch of ?6)-d-Manp-(1?; ?2)-d-Glcp-(1?. This discovery opens up avenues for the production of EPS for food industries, functional foods, and biomedical applications.
