Abstract
La invención comprende un proceso para producir un derivado de quitosano, y un producto preparado mediante el mismo, al activar quitosano o una quitina como precursor de quitosano en alcohol que contiene agua en una cantidad que abarca del 0% a un máximo de aproximadamente el 30% y preparar derivados mediante reacción con un reactivo para obtener derivados que tienen varios usos, con inclusión de uso como antimicrobicidas, microbiostáticos, antitranspirantes, antifúngicos, o conservantes de frutas, o como portadores de moléculas activas o grupos funcionales etc., o una combinación de los mismos. Los derivados ilustrados incluyen derivados de ácidos, succínicos, desacetilados a nivel enzimático, hidrolizados a nivel enzimático, azúcar, formaldehído, ácido fosfórico, ácido clorhídrico y sulfato de cobre que son obtenidos mediante reacción individual o en combinación con reacciones consecutivas. También se revela una clase novedosa de proteo-quitinasa termoestable preparada a partir de Aspergillus niger MTCC 5572 que tiene un peso molecular sobre SDS-PAGE de aproximadamente 50 kD y actividad hidrolítica óptima a pH 2 y 80 ºC. También se revelan composiciones para tratamientos de productos naturales y métodos para retardar el añejamiento, mejorar la vida útil y retardar la putrefacción microbiológica de plátanos y otras frutas.
