“…Members of the molds, as majority of microscopic forms, inhabit lignin-rich environments, and their relative lignin-degrading potential is worth of being studied. It was shown that some of them, such as Aspergillus fumigatus, A. japonicus, A. niger, and A. terreus, Penicillium simplicissimum, were capable of degrading both aromatic and carbohydrate components of water-soluble lignocarbohydrate complexes (LCC) or Kraft lignin (Milstein et al 1984;Zeng et al 2006). Although the function of mold species was noticed, few studies have so far described mold species occurring biodegradation of alkali lignin.…”

A fungus strain F-3 was selected from fungal strains isolated from forest soil in Dalian of China. It was identified as one Aspergillus sp. stain F-3 with its morphologic, cultural characteristics and high homology to the genus of rDNA sequence. The budges or thickened node-like structures are peculiar structures of hyphae of the strain. The fungus degraded 65% of alkali lignin (2,000 mg l(-1)) after day 8 of incubation at 30°C at pH 7. The removal of colority was up to 100% at 8 days. The biodegradation of lignin by Aspergillus sp. F-3 favored initial pH 7.0. Excess acid or alkali conditions were not propitious to lignin decomposing. Addition of ammonium L: -tartrate or glucose delayed or repressed biodegradation activities. During lignin degradation, manganese peroxidase (28.2 U l(-1)) and laccase (3.5 U l(-1))activities were detected after day 7 of incubation. GC-MS analysis of biodegraded products showed strain F-3 could convert alkali lignin into small molecules or other utilizable products. Strain F-3 may co-culture with white rot fungus and decompose alkali lignin effectively.

“…Research has shown that lignin is oxidised and degraded by a ligninase system (Lechner and Papinuti, 2006;Zeng et al, 2006;Elisashvili et al, 2008;Rodrigues et al, 2008) composed by lignin Modification of wheat straw lignin by solid state fermentation with white-rot fungi 24 peroxidase (LiP), manganese peroxidase (MnP) and laccase. In addition, cellulases, hemicellulases and esterases are also considered to be extremely important in the degradation process of lignocellulosic biomass (Ghatora et al, 2006;Tabka et al, 2006;Panagiotou et al, 2007).…”

“…Aunque está reportado que Aspergillus y Penicilllium spp son eficaces en la degradación de la lignina (13,22), no se ha descrito su capacidad en la producción de aromáticos a partir de pajas agrícolas ya que los estudios se han enfocado principalmente en basidiomicetos y en la transformación de aromáticos intermediarios. Por ejemplo con Trametes versicolor a partir de ácido ferúlico se generó alcohol veratrílico y veratrilaldehido (23), mientras que con Pycnoporus cinnabarinus se liberó vainillina con un rendimiento de 0,064 mg mL -1 en 7 días (9).…”

RESUMENAntecedentes: La paja de trigo es un residuo agrícola con un 17% de lignina, un polímero recalcitrante con potencial biotecnológico si se despolimeriza en aromáticos de interés para la industria; lo que es posible por métodos químicos, pero que son costosos y contaminantes. Una alternativa es su despolimerización biológica por hongos mitospóricos ligninolíticos como Aspergillus y Penicillium spp. Sin embargo existen pocos reportes del uso de hongos en la generación de aromáticos por despolimerización de la lignina de residuos agrícolas. Objetivo: Determinar la generación de aromáticos utilizando los hongos Aspergillus y Penicillium por despolimerización de la lignina residual de paja de trigo semipurificada. Métodos: Para ello los hongos se cultivaron en lignina residual de paja de trigo por 28 días, que por despolimerización generaron aromáticos que se identificaron en cromatografía de gases. Resultados: Los resultados mostraron que ambos hongos generan aromáticos como: guayacol 3,5, vainillina 3,3, ácidos hidroxibenzoico 3,2, vainillinico 3,3, siringico 10,1 y ferúlico 21,9 mg mL -1. Conclusiones: Aspergillus y Penicillium son una opción ecológica en el aprovechamiento de la lignina residual de paja de trigo semipurificada para la generación de aromáticos de interés industrial, en un tiempo relativamente corto a partir de un residuo abundante y barato.Palabras clave: ascomiceto, despolimerización, hongo, mitospórico, ligninolítico. ABSTRACT Background:Wheat straw is an agricultural waste, which contains 17% of lignin, a recalcitrant polymer with biotechnological potential provided it is depolymerized. Lignin depolymerization has attracted interest because it yields aromatics of industrial interest; chemical and physical methods are available but entail economic and environmental constraints. An alternative is to exploit the ligninolytic capacity of mitosporic fungi, such as Aspergillus and Penicillium spp. There are few reports on the use of these funguses in the generation of aromatics by lignin depolymerization. Objetives: To use Aspergillus and Penicillium spp in the biological generation of aromatics from semipurified residual wheat straw lignin. Methods: Funguses were grown in semipurified residual wheat straw lignin for 28 days; produced aromatics were followed using gas chromatography. Results: Obtained results indicate a range of aromatics produced, i.e. 3,5 mg mL -1 guaiacol, 3,3 vanillin, 3,2 hydroxybenzoic acid, 3,3 vanillinic, 10,1 syringic and 21,9 ferulic. Conclusions: Aspergillus and Penicillium represent an ecological option in the exploit of semi-purified residual lignin from wheat straw to generate aromatics in a shorter period from an abundant and cheap residue.
