Degradación microbiana de subproductos lignocelulósicos

Abstract

La lignina, junto a la celulosa, es el polímero más abundante en la naturaleza. Se ha estimado que la producción anual de biomasa terrestre es de 100 x 10(elevado a 9) toneladas, de las que 20 x 10 (elevado a 9) toneladas corresponden a lignina (Bassharn,1975). Normalmente, el concepto lignina se suele asociar al de madera, ya que es en el xilema de árboles y arbustos donde en encuentra más abundantemente, en proporción del 20 al 30%. En una fibra típica de madera, la lámina media posee la mayor concentración de lignina (60-90%), de entre todas las capas que forman la pared celular, lo que representa el 10-30% del total de lignina en la fibra. La concentración de lignina en las paredes celulares primaria y secundaria es relativamente baja, pero representa el 70-90% del total de lignina. Sin embargo, también existe lignina, en mayor o menor cantidad, en otras partes de la planta, como raices, frutos, semillas,etc. Los tallos de helechos, hierbas e incluso algunos musgos contienen elevados porcentajes de lignina, respecto a su biomasa total.
