摘要:
The present invention relates to a cosmetic for skin roughness improvement/skin care containing a biosurfactant, particularly MEL-A, MEL-B or MEL-C.
摘要:
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.
摘要:
A microorganism of the present invention is Dirkmeia churashimaensis (NITE BP-03054), Papiliotrema flavescens (NITE BP-03051), Papiliotrema flavescens (NITE BP-03052), or Apiotrichum porosum (NITE BP-03053).
摘要:
There is provided a novel sophorolipid derivative having high water solubility and surface activity. A plurality of sophorolipid derivatives having a novel structure is isolated and purified from a cultured product of sophorolipid producing microorganism ( Starmerella bombicola, etc.)
(wherein, R 1 to R 3 are each independently hydrogen, a fatty acid ester having 2 to 22 carbon atoms, or the above SL group, provided that at least one of R 1 to R 3 is the SL group in which R are the same or different and each represent hydrogen or an acetyl group and R n is a linear or branched alkyl or alkenyl group having 13 to 21 carbon atoms).
摘要:
Provided is a means for increasing mannosylerythritol lipid (MEL) production efficiency. The present invention is a mannosylerythritol-lipid-producing microorganism transformed with an expression vector having a gene that encodes a lipase under the control of E5Pgap promoter or E5Ptef promoter.
摘要:
The present disclosure relates to a microorganism (NITE BP-03572) belonging to Rhodosporidiobolus azoricus or to a microorganism (NITE BP-03573) belonging to the genus Vanrija.
摘要:
Provided is a means for efficiently producing a monoacyl MEL. This means comprises culturing a monoacyl-MEL-producing microorganism in the presence of a surfactant.
