Abstract
In the present study, a new candidate gene, bglH_3 , responsible for the β-glucosidase-positive phenotype in L. plantarum was detected, providing the basis for the future marker-assisted selection of L. plantarum starter strains with a β-glucosidase-positive phenotype. Furthermore, the ability of selected strains to hydrolyze oleuropein at low temperatures is important for application as starter cultures on an industrial scale.
