In the present study, a new candidate gene,bglH_3 , responsible for the β-glucosidase-positive phenotype inL. plantarum was detected, providing the basis for the future marker-assisted selection ofL. 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.
