NOVEL WEISSELLA CIBARIA STRAIN AND FOOD COMPOSITION FOR PREVENTING OR AMELIORATING OBESITY OR FATTY LIVER DISEASE, COMPRISING WHEY FERMENTATION PRODUCT THEREOF

摘要

The present invention relates to a Weissella cibaria KI35 strain with accession number KACC 81117BP exhibiting anti-obesity activity during whey fermentation; a food composition, a food additive composition, a pharmaceutical composition, and a feed composition for preventing or ameliorating obesity or fatty liver disease, comprising a whey fermentation product bioconverted with the strain; a method for preventing or treating obesity or fatty liver disease, comprising the step of administering the pharmaceutical composition to an individual; and a use of a composition comprising a whey fermentation product bioconverted with a Weissella cibaria strain. The whey fermentation product bioconverted with the Weissella cibaria KI35 strain in the present invention reduces a weight gain rate through inhibition of pancreatic lipase activity, inhibition of α-amylase and α-glucosidase activity, and inhibition of obesity cell differentiation, and reduces the expression of proteins and genes related to obesity and inflammation in organs such as the liver and adipose tissue, thereby exhibiting the effects of preventing, ameliorating, or treating obesity and fatty liver disease.
