This study was to investigate whether the bioactivity of L. plantarum L67 can be enhanced by treatment with Zanthoxylum piperitum DC (ZPDC) glycoprotein or compounds of similar molecular weights (24 kDa). When L. plantarum L67 was treated with ZPDC glycoprotein of various concentrations, the intensities of a few SDS-PAGE bands were slightly changed. The amount of a 23-kDa protein was increased upon treatment with increasing concentrations of ZPDC glycoprotein. The activities of antioxidant enzymes (SOD, GPx, and CAT), growth rate, and β-galactosidase activity were more increased at treatment with ZPDC glycoprotein than at treatment of L. plantarum L67 only, whereas the ATPase activity was decreased. Interestingly, it did not affect scavenging activity for the DPPH. The founding result suggest that, one of beneficial strategies for increase the bioactivity of L. plantarum L67 might be to take ZPDC.
