Abstract

Se refiere a un proceso para producir un derivado de quitosano mediante reaccion con un reactivo capaz de formar complejos mediante fuerzas fisicas que incluyen adsorcion, o mediante fuerzas quimicas que incluyen enlace covalente, para preparar un derivado, caracterizado porque en el proceso al activar quitosano o una quitina como precursor de quitosano en alcohol que contiene agua en una cantidad que abarca del 0% a un maximo de aproximadamente el 30% y preparar derivados mediante reaccion con un reactivo para obtener derivados que tienen varios usos. Tambien 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 hidrolitica optima a pH 2 y 80 °c. Tambien se revelan composiciones para tratamientos de productos naturales y metodos para retardar el anejamiento, mejorar la vida util y retardar la putrefaccion microbiologica de platanos y otras frutas como conservante. Tambien pueden ser utiles como microbicidas, microbiostaticos, antitranspirantes y antifungicos.
