A composition containing 3-hydroxyanthanilic acid (3HAA) and a compound that alters iron homeostasis (an iron chelator or an iron supplement). The combination may be used as a new antibiotic drug. Combining 3HAA with iron chelation may have the dual benefit of inhibiting pathogen growth while repressing the pathological hyperinflammatory response in septic individuals. The combination may be effective at preserving food by preventing bacterial growth.

The present invention relates to the use of polyaminoisoprenyl derivatives in antibiotic or antiseptic treatment of bacteria including those presenting multiple drug resistance (MDR), in particular as efflux pump inhibitors. It also relates to novel polyaminoisoprenyl derivatives, compositions comprising the same, process for preparing the same, and use thereof in antibiotic or antiseptic treatment.

The combination of EGCG and a derivative of a basic amino acid has been found to be an effective anti-yeast agent in acidic food. The present invention relates to a method for controlling or preventing the growth of yeast in acidic food (i.e. with a pH between 2 and 6) comprising adding to said food a) epigallocatechin gallate (EGCG) and b) a derivative of a basic amino acid, and/or a salt thereof, as an anti-yeast agent. The present invention further relates to a composition for addition to food and to an acidic food comprising said composition.

Mixture for the antifungal, antibacterial and antiviral treatment of plants and of ingredients or foods intended for human and/or zootechnical consumption includes: at least one chitosan or at least on salified chitosan from 35% to 85 % by weight, at least one cationic surfactant from 0.05% to 40% by weight, at least one compound containing copper from 0.1% to 10% in the case of mixtures intended for treatment for human or animal nutrition and from 10% to 40% in the case of mixtures intended for the control of fungal diseases in plants at least one inorganic acid from 2% to 20% by weight, and/or at least one organic acid from 10% to 20%, with an overall pH between 2.0 and 8.4.

A functional water containing a polyfunctional amine and/or a salt thereof as a functional component, wherein the total content of water, the polyfunctional amine, and the salt of the polyfunctional amine is 95% by weight or more. The polyfunctional amine is at least a specific polyamine, a polymer having a structural unit derived from a specific cyclic amine, or a polymer having a structural unit derived from a specific unsaturated amine. The total content of the polyfunctional amine and/or salt thereof is preferably 0.0001 to 10000 ppm by weight. The functional water has functions including freshness-keeping for foods, aging of foods, antisepsis, deodorization, adjustment of plant growth, life extension for cut flowers, flowering control for cut flowers, pest control, pest repellence, improvement of bowel movement, reduction of fecal odor, reduction of blood pressure, increase of body temperature, improvement of the intraoral environment, prevention of halitosis, and prevention of body odor.

What is disclosed is a method of reducing undesirable concentrations of microorganisms without the use of man-made antibiotics, comprising the steps of: introducing a quantity of fermentable carbohydrate; sugar or cellulose to an aqueous system; introducing a quantity of desirable microorganism to the aqueous system; introducing at least one acid into the aqueous system, wherein the at least one acid is selected from the group consisting of hops acid, organic acid, or a combination of hops acid and organic acid; and introducing a compound comprised of Lauryl-L-arginine ethyl ester monohydrochloride (LAE) into the aqueous system. The use of LAE as a preservative of distiller's grains and solubles is also disclosed.
