Methods and compositions of reducing and preventing bacterial growth and the formation of biofilm on a surface utilizing chitosan-derivative compounds

摘要

A method of treating a surface, the method comprising contacting (e.g., spraying) an effective amount of a composition comprising a chitosan (e.g., soluble or derivatized chitosan) with the surface, thereby treating the surface. Non-pharmaceutical compositions (e.g., liquid or dry powder compositions) include chitosan (e.g., a soluble or derivatized chitosan). The compounds and compositions described herein are biocompatible (e.g., non-toxic) and/or biodegradable (e.g., eco-friendly). Methods using the compositions described herein include methods of treating a surface (e.g., an inert and/or non-animal surface, e.g., a synthetic or semi-synthetic surface (e.g., cellulose, ceramic, plastic, metal, glass, wood, or stone); or a food or food product surface, the method comprising contacting (e.g., spraying) an effective amount of a composition comprising a chitosan (e.g., a soluble or derivatized chitosan described herein) with the inert and/or non-animal surface, or the food or food product surface, thereby treating the surface.
