Resumen
En este estudio se prepararon microcápsulas del conjugado lignina -proteína - quitosano. Con el objetivo de preparar
"monómeros bien defmidos (fenoles)", y utilizarlos en la síntesis de las microcápsulas, se realizó la fragmentación vía
enzimática de diferentes ligninas. La producción de los fenoles se realizó en un reactor con una suspensión de la lignina a
un pH 6.8, en buffer de citrato 1 M, durante 6 horas a 37ºC y utilizando enzimas de los cultivos de G. trabeum y P.
chrysosporiumin.
En la preparación de las microcápsulas se empleó una disolución de quitosano en ácido acético, el cual fue mezclado con
una disolución acuosa de lignina - proteína. El conjugado de lignina - proteína -quitosano se obtuvo mediante la
interacción por enlaces de hidrógeno, producto de la disponibilidad de grupos amino e hidroxilo de los constituyentes.
Esta interacción permitió el desarrollo de materiales estables tales como nanopartículas y biomembranas, las cuales
poseen un potencial novedoso en aplicaciones en la industria médica y de la agronomía.

With the aim of preparing "well-defined monomers (phenols)", and use them in the synthesis of the microcapsules, the fragmentation was carried out via enzymatic of different lignins. The production of phenols was carried out in a reactor with a lignin suspension at pH 6.8, in 1 M citrate buffer, for 6 hours at 37ºC and using enzymes from G. trabeum and P. cultures. chrysosporiumin. In the preparation of the microcapsules, a solution of chitosan in acetic acid was used, which was mixed with an aqueous solution of lignin - protein. The lignin-protein-chitosan conjugate was obtained by interaction by hydrogen bonds, product of the availability of amino and hydroxyl groups of the constituents. This interaction allowed the development of stable materials such as nanoparticles and biomembranes, which They have novel potential for applications in the medical and agronomy industries.
