The invention is directed to a biocidal composition formed by a reaction or combination of electrolyzed water and an amine, and methods for using same to kill or control microorganisms, such as viruses, bacteria, fungi and algae.

The present invention relates generally to methods for forming peroxyformic acid, comprising contacting formic acid with hydrogen peroxide. The methods for forming peroxyformic acid can include adding formic acid with a relatively lower concentration of hydrogen peroxide, or adding formic acid to a peroxycarboxylic acid composition or forming composition to react with hydrogen peroxide in the compositions. The present invention also relates to peroxyformic acid formed by the above methods. The present invention further relates to the uses of peroxyformic acid for treating a variety of targets, e.g., target water, including target water used in connection with oil- and gas-field operations. The present invention further relates to methods for reducing or removing H.sub.2S or iron sulfide in the treated water source, improving clarity of the treated water source, or reducing the total dissolved oxygen or corrosion in the treated water source, using peroxyformic acid, including peroxyformic acid generated in situ.

The present invention relates to the field of antimicrobial agents. In particular, the present invention relates to polypeptides comprising the sequence of a peptidoglycan hydrolase and a peptide sequence heterologous to the peptidoglycan hydrolase wherein said heterologous peptide sequence comprises a specific sequence motif which is 16, 17, 18, 19 or 20 amino acids in length. The present invention relates also to corresponding nucleic acids, vectors, bacteriophages, host cells, compositions and kits. The present inventions also relates to the use of said polypeptides, nucleic acids, vectors, bacteriophages, host cells, compositions and kits in methods for treatment of the human or animal body by surgery or therapy or in diagnostic methods practiced on the human or animal body. The polypeptides, nucleic acids, vectors, bacteriophages, host cells, compositions and kits according to the invention may also be used as an antimicrobial in, e.g., food or feed, in cosmetics, or as disinfecting agent.

An antimicrobial peptide variant having an amino acid sequence selected from SEQ ID NOs: 2-30 is provided. The antimicrobial peptide variant can have antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, Staphylococcus aureus MRSA, Staphylococcus epidermidis, Cutibacterium acnes, or Clostridium perfringens. A composition, pharmaceutical composition, food additive, cosmetic composition, or hygiene product having an antimicrobial peptide variant including an amino acid sequence selected from SEQ ID NOs: 2-30 is also provided. The antimicrobial peptide can be an active ingredient in such compositions, additives, and products. A method of treating an infectious disease caused by bacteria is also provided. The method can include administering a pharmaceutical composition having the antimicrobial peptide as an active ingredient.

A process of forming a confectionery product includes heating a confectionery mixture comprising a sweetened milk product and fat while stirring until the confectionery mixture reaches a predetermined consistency. The process also includes forming the confectionery product upon cooling of the confectionery mixture. The confectionery product has a water activity of about 0.59 or greater, has a sugar content of about 87 degrees Brix or less, and has a shelf life of about three months or greater. A confectionery product includes a confectionery mixture. The confectionery product includes a sweetened milk product, butter, cocoa powder, a sweetener, and a preservative. The sweetener is corn syrup, inulin, tapioca syrup, maltodextrin, pear puree, and/or a combination thereof. The confectionery mixture has a water activity of about 0.59 or greater, has a sugar content of about 87 degrees Brix or less, and has a shelf life of about three months or greater.

This disclosure provides generally for antimicrobial compositions and methods of use comprising an anthocyanin, an anthocyanidin or metabolites thereof. Methods for promoting healing of a wound using these compositions are also disclosed. These compositions have broad spectrum antimicrobial activity and are safe for human and animal uses. Further, these compositions are safe for medical uses and industrial uses as antiseptic preparations to reduce or prevent microbial growth, including killing bacterial biofilms.

This invention relates to a process for improving the shelf life of a baked product by applying natamycin on the outer surface.

A method for treating a microorganism or inflammation caused by the microorganism includes administering or applying a composition comprising an antimicrobial peptide with the amino acid sequence of SEQ ID NO: 1 to a subject in need thereof. Because the antimicrobial peptide with the amino acid sequence of SEQ ID NO: 1 exhibits an excellent antimicrobial activity against Gram-negative bacteria and Gram-positive bacteria and also low cytotoxicity for human erythrocytes, it can be advantageously used for various applications.

The object of the present invention is a composition in powder form comprising the following polysaccharides alginic acid or sodium alginate,—pectin, chitosan, wherein the % by weight of the polysaccharides is at least 20% with respect to the total weight of the powder. The process for preparing said powder by an atomization process and its use in the treatment of cutaneous wounds and in the sector of food preservation are additional objects of the invention. Moreover, additional objects of the invention are the composition in the form of solution or liquid suspension that represents the starting material to obtain said powder and the process for preparing said liquid composition.

The present invention concerns the field of food preservation and more specifically compositions comprising xanthohumol for use as an anti-microbial agent in the preservation of food in combination with another antimicrobial agent. In particular, the present invention provides the use of compositions comprising xanthohumol and a further antimicrobial agent, as an anti-microbial composition against lactic acid bacteria. Such compositions and food products comprising such compositions are also encompassed by the invention.
