4 results about "M-anisic acid" patented technology

The present invention generally relates to a formulation comprising at least two of compounds A, B and C, (A) maltol, (B) anisic acid, (C) an alkanediol, as well as at least one of, components D, E, and F, (D) an emulsifier, (E) an oil component, and (F) a water component.

The invention relates to cosmetic and dermatological preparations comprising a combination of levulinic acid and anisic acid. The preparations according to the invention are particularly suitable for application to the skin. These preparations exhibit selective antibacterial action on the skin, specifically targeting anaerobic bacteria of the skin flora, while having little or no bactericidal action against aerobic bacteria. The compositions according to the invention are therefore suitable for cosmetic skin care as well as for the dermatological treatment of certain skin conditions, such as acne.

The present invention provides a recombinant Escherichia coli for synthesizing anisic acid from scratch, wherein at least one of the following improvements is made to the starting strain of Escherichia coli: (1) overexpressing O-methyltransferase PSA-OMT1 from Pleurotus sapidus; overexpressing chorismate lyase UbiC from E. coli MG1655 or Providencia rustigianii; (2) overexpressing a feedback inhibition mutant AroG of 3-deoxy-D-arabino-heptanoic acid 7-phosphate (DAHP) synthase from E. coli MG1655 on the basis of (1); D146N (3) Based on (2), the enzyme PpsA derived from phosphoenolpyruvate (PEP) synthase was overexpressed, and the pykF gene encoding pyruvate kinase I was knocked out. Thus, the recombinant E. coli of the present invention can achieve accumulation of anisic acid in the fermentation broth during the fermentation process, and the maximum anisic acid yield of the recombinant E. coli in a shake flask can reach 284.9 mg / L, laying the foundation for the subsequent construction of high-yield anisic acid engineered bacteria.
