Abstract

Abstract: Saccharomyces cerevisiae strains (KU200278 and KU200281) were isolated from cucumber jangajji and their probiotic properties and production of β-glucan, glutathione, and glutathione derivatives were investigated as compared with that of the commercial strain. S. cerevisiae strains were highly resistant to artificial gastric and bile juice and S. cerevisiae KU200281 showed higher adhesion ability. The assay of enzymatic activities revealed that all strains tested did not produce carcinogenic enzyme, β-glucuronidase. The antibiotic tolerance of the yeast strains was assessed against eight antibiotics (ampicillin, chloramphenicol, ciprofloxacin, doxycycline, gentamycin, kanamycin, streptomycin, and tetracycline), and all strains were resistant according to the CLSI performance standards. All strains showed DNA protection capacity against reactive oxygen species. β-Glucan, glutathione, and l -ornithine contents of S. cerevisiae KU200281 was higher in tested S. cerevisiae . In summary, our results reveled that S. cerevisiae KU200281 demonstrated probiotic potential and could be used as a probiotic substance for the production of functional products. Highlights: Saccharomyces cerevisiae (KU200278 & KU200281) was isolated from cucumber jangajji. Yeast strains showed high stability and adherence in gastric intestinal conditions. Yeast strains showed safety by antibiotics, hemolysis, and DNA breakage. S. cerevisiae KU200281 exhibited increased β-glucan and glutathione contents. S. cerevisiae KU200281 might be used as a probiotic strain for functional products.
