Activator including biosurfactant as active ingredient, mannosyl erythritol lipid, and production method thereof

Abstract

The present invention includes as an active ingredient at least one biosurfactant, in particular mannosyl alditol lipid (such as MEL and MML) or triacylated mannosyl alditol lipid. This allows providing an activator and anti-aging agent that is excellent in activating and anti-aging effects on cells and that is safe enough to be used for a long time, and also providing cosmetics, quasi-drugs, drugs, and drinks and foods including the activator and the anti-aging agent as active ingredients. Further, the present invention provides MEL whose mannosyl erythritol skeleton in a molecular structure is 1-O-β-D-mannopyranosyl-meso-erythritol and a method for producing the MEL with use of a microorganism.
