Policatión, antifúngico, antibacteriano, mecanismos de acción.Resumen
En la actualidad, las restricciones en el uso de compuestos químicos sintéticos en la producción, procesamiento y conservación de los alimentos, así como en la salud humana y animal, han permitido una demanda importante de materiales versátiles para su uso en dichas áreas. El quitosano es un biopolímero catiónico que, además de ser un compuesto seguro, posee propiedades antifúngicas y antibacterianas, características que lo posicionan como un material importante. Los reportes de la actividad antimicrobiana del quitosano datan de los años 80´s; sin embargo, estudios in vitro e in vivo muestran la importancia de analizar las nuevas características de esta molécula. Asimismo, en la última década, diversos grupos de investigación se han dado a la tarea de estudiar sus mecanismos de acción, cuyos resultados han permitido el planteamiento de diversos modelos, los cuales se basan en la interacción del quitosano con diferentes blancos celulares.
