Abstract: Novel lactic acid bacterium L8 strain and a composition including the same L8 strain, the composition having blood glucose level reducing action, a lipid metabolism improving action, an antioxidant action, an antiobesity action, a fatty liver suppressing action, a hepatitis preventing action, a liver function improving action, and an intestinal environment improving action. A Lactococcus lactis subsp. lactis L8 strain derived from Amur cork living in the Shirakami Mountains, a composition containing the strain, and a medium and a method for efficiently culturing the strain.

Abstract: [Problem] To provide a phospholipid ?-linolenic acid composition of consistent quality and having a stable supply of source material, with focus on Torula yeast, which is edible and recognized as safe, in order to resolve issues with omega 3 sources. [Means for Solving the Problem] As a result of intensive study to resolve the above-noted issues, the inventors of the present invention have discovered that a phospholipid ?-linolenic acid composition can be obtained using residue of yeast extract extracted from Torula yeast (Candida utilis), for example, which is currently produced in large quantities for application in foods, and so arrived at the present invention.
