Utilización del sistema enzima-mediador para la eliminación de los compuestos extraíbles y la lignina en la industria de pasta y papel

Abstract

La madera y otros materiales lignocelulósicos representan la mayor fuente de energía y materia orgánica renovables de la biosfera. La mayor parte de la biomasa del planeta está constituida por materiales lignocelulósicos, por lo que la degradación de estos compuestos representa el proceso biodegradativo más importante en el ciclo del carbono. Los materiales lignocelulósicos incluyendo los productos de origen agrícola y forestal, están constituidos por tres polímeros estructurales- celulosa, hemicelulosa y lignina- y una serie de compuestos de bajo peso molecular solubles en agua o en solventes orgánicos, los denominados extraíbles. La celulosa es el componente mayoritario (alrededor de un 50%), seguida de la lignina (alrededor de un 20%) y de la hemicelulosa (15%) (Fengel y Wegener, 1984). También presentan pequeños contenidos de proteínas y sales minerales (estimadas como ceniza tras la combustión). La madera es el más abundante de los materiales lignocelulósicos y su estructura y composición condiciona su utilización industrial y la posible aplicación de métodos biotecnológicos

Financiado por el proyecto europeo: “White biotechnology for added value products from renewable plant polymers: Design of Taylor-made biocatalysts and new industrial bioprocesses (BIORENEW)” NMP2-CT- 2006-026456 y un contrato I3P de postgrado.
