The purpose is achieved by a composition for activating hair follicle stem cells, which comprises: at least one first active ingredient selected from the group consisting of 10-hydroxy-2-decenoic acid, derivatives thereof, and salts thereof; and at least one second active ingredient selected from the group consisting of 2-decenoic acid, derivatives thereof, and salts thereof.

The present application relates to a kind of containing fatty acyl-coa dehydrogenase engineering bacteria and its application method, belong to microbial fermentation technical field.The engineering bacteria containing fatty acyl-coa dehydrogenase gene in the present application include fatty acyl-coa dehydrogenase gene and fatty acyl-coa thioesterase gene, the fatty acyl-coa dehydrogenase gene is derived from Candida tropicalis or Yarrowia lipolytica, its nucleotide sequence is SEQ ID NO.1 or SEQ ID NO.2;The nucleotide sequence of the fatty acyl-coa thioesterase gene is SEQ ID NO.3.Fatty acyl-coa dehydrogenase from Candida tropicalis and Yarrowia lipolytica, combined with existing fatty acyl-coa thioesterase, jointly convert 10-hydroxy decanoic acid, significantly improve the conversion rate of 10-hydroxy-2-decenoic acid, so that the industrialization production of 10-hydroxy-2-decenoic acid becomes possible.

This invention belongs to the field of cosmetic technology, specifically relating to a composition containing 10-hydroxy-2-decenoic acid and its application. The composition is obtained by compounding probiotic-fermented brown algae, pterostilbene, and 10-hydroxy-2-decenoic acid in a certain proportion. Experiments have shown that the components of the above composition can produce a synergistic effect, significantly inhibiting the production of inflammatory factors, resisting inflammatory aging, and inhibiting lipid peroxidation. Furthermore, this invention unexpectedly discovered that compounding probiotic-fermented brown algae, 10-hydroxy-2-decenoic acid, and pterostilbene can significantly improve the light and heat stability of pterostilbene, thus possessing good practical application value.

The invention provides a method of microbial control in water comprising adding to the water one or more bromine-based biocide(s) and cis-2-decenoic acid or a salt thereof. Compositions in the form of liquid concentrates comprising bromine-based biocides and cis-2-decenoic acid or a salt thereof are also described.

The invention discloses an application of 10-hydroxy-2-decenoic acid (10-HDA) or a salt thereof in medicine preparation, and an application of the compound in treatment or prevention of cardiovascular diseases, especially acute myocardial infarction. According to the application, generation of inflammatory factors and active oxygen is inhibited by regulating and controlling a TLR4 / MyD88 / NF-kappa B signal channel, the anti-inflammatory and anti-oxidative stress effects are achieved, and therefore cardiac dysfunction and heart diseases caused by myocardial infarction are relieved.
