Abstract: The present invention relates to a strain selected from the group consisting of Saccharomyces cerevisiae KCTC14779BP, Saccharomyces cerevisiae KCTC14780BP, Lactobacillus fructivorans KCTC14776BP, Bacillus paramycoides KCTC14777BP, and Bacillus megaterium KCTC14778BP; and a cosmetic composition, a quasi-drug composition, or a food composition comprising any one or more selected from the group consisting of the strain, a culture of the strain, a fermented product of the strain, and a fraction of the culture or fermented product. Since the Saccharomyces cerevisiae, Lactobacillus fructivorans, Bacillus paramycoides or Bacillus megaterium strain, a culture of the strain, a fermented product of the strain, or a fraction of the culture or fermented product has excellent effects of improving skin and soothing sensitive skin, it can be widely used as cosmetic compositions, quasi-drug compositions, and food compositions for skin improvement.

Abstract: The present invention relates to a Gluconobacter thailandicus strain deposited under Accession No.
