    Abstract

    Lactobacillus gasseri ATCC33323T has seven putative phospho-β-glycosidase genes. Using column chromatography, we found that this strain cultured in lactose medium expresses five phospho-β- glycosidases (LacG1, LacG2, Pbg1, Pbg2, and Pbg3), where these gene expressions can be suppressed by glucose. To our knowledge, this is the first report indicating that five glycosidases are induced from a single bacterial strain using a single carbon source, lactose.
