Nα-long chain alkanoyl di basic amino acid alkyl ester salts and glycerol monofatty acid ester antimicrobial combo
US Patent 8193244
Publication date: June 5, 2012
Assignee: Nevada Naturals, Inc.

Disclosed in this patent is the combination of Nα-long chain alkanoyl di basic amino acid alkyl ester salts with glycerol monofatty acid esters, which according to the inventors, results in biocidal synergy and the extension of cidal activity of the di basic amino acid derivative. This technology can be applied in a variety of antimicrobial applications such as oral care, wound care, dermatological care, animal care, and cosmetic applications. The invention provides several advantages not observed by using Nα-long chain alkanoyl di basic amino acid alkyl ester salts alone.

Polypeptides having antimicrobial activity and polynucleotides encoding same
US Patent 8192925
Publication date: June 5, 2012
Assignee: Novozymes Adenium Biotech A/S

This patent describes isolated polypeptides having antimicrobial activity and isolated polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors and host cells comprising the polynucleotides as well as methods for producing and using the polypeptides. Thus, the antimicrobial polypeptides of the invention may by useful as disinfectants, e.g., in the treatment of infections in the eye, mouth or skin; in antiperspirants or deodorants; or for cleaning and disinfecting contact lenses and teeth.
