Title
(EN) WEISSELLA VIRIDESCENS STRAIN AND USES THEREOF FOR THE SYNTHESIS OF EXOPOLYSACCHARIDES
(FR) SOUCHE DE WEISSELLA VIRIDESCENS ET SES UTILISATIONS POUR LA SYNTHÈSE D'EXOPOLYSACCHARIDES
Abstract
(EN)
The present invention relates to a strain of the species Weissella viridescens with accession number CECT 9735 that displays a significantly increased ability to synthesize exopolysaccharides (EPS) compared to other strains of the same genus in the prior art. Specifically, the strain of the invention described herein comprises a polynucleotide sequence encoding an enzyme responsible for the synthesis of said EPS, wherein said sequence is comprised in a mobile element and not in the cell genome. Furthermore, this invention relates to the EPS, per se, secreted by said cell, as well as the said EPS production method.
(FR)
La présente invention concerne une souche de l'espèce Weissella viridescens ayant pour numéro d'enregistrement CECT 9735 qui présente une capacité significativement accrue à synthétiser des exopolysaccharides (EPS) par comparaison avec d'autres souches du même genre selon l'état de la technique. Plus particulièrement, la souche selon l'invention décrite dans la description comprend une séquence polynucléotidique codant pour une enzyme responsable de la synthèse desdits EPS, ladite séquence étant comprise dans un élément mobile et non dans le génome de la cellule. En outre, la présente invention concerne les EPS, en eux-mêmes, sécrétés par ladite cellule, ainsi que ledit procédé de production d'EPS.
