Biological pretreatment of rice husks with the white-rot fungus pleurotus ostreatus: the role of laccase activity
El objetivo principal de la investigación fue determinar la influencia de la composición del medio de cultivo y los compuestos lignocelulósicos en la secreción de enzimas lacasas por P. ostreatus en cultivos sumergidos. ... -
Catalytic hydroprocessing of lignin β-O-4 ether bond model compound phenethyl phenyl ether over ruthenium catalysts
The catalytic hydroprocessing of phenethyl phenyl ether (PPE), a model compound of one of the most significant ether linkages within lignin structure, β-O-4, has been studied. Reactions were carried out using two ruthenium-based ... -
Diseño y fabricación 3D de componentes para reactores de despolimerización de lignina: Batch y continuo
La lignina es uno de los tres componentes poliméricos principales de la biomasa junto a la celulosa y hemicelulosa. Está presente en materias de origen vegetal como la madera, por lo que altas cantidades de lignina se ... -
Expresión génica de peroxidasas ligninolíticas en Pleurotus ostreatus: regulación por temperatura y pH
Pleurotus ostreatus es un hongo comestible de gran importancia biotecnológica por ser un organismo modelo degradador de lignina. Su genoma contiene nueve genes codificantes de peroxidasas ligninolíticas, características ... -
Genome, transcriptome, and secretome analysis of wood decay fungus Postia placenta supports unique mechanisms of lignocellulose conversion
Brown-rot fungi such as Postia placenta are common inhabitants of forest ecosystems and are also largely responsible for the destructive decay of wooden structures. Rapid depolymerization of cellulose is a distinguishing ... -
Olive industry liquid waste from trash to metal adsorbent for wastewater purifcation
The development of biobased polymeric materials for wastewater purification has become a demand due to the growing need for water free of hazardous metal ions for safe purposes. The organic components of the OLLW including ... -
Production of aromatic compounds by catalytic depolymerization of technical and downstream biorefinery lignins
Lignocellulosic materials are promising alternatives to non-renewable fossil sources when producing aromatic compounds. Lignins from Populus salicaceae., Pinus radiata and Pinus pinaster from industrial wastes and biorefinery ... -
The proteome of Medicago truncatula in response to ammonium and urea nutrition reveals the role of membrane proteins and enzymes of root lignification
Plants differ widely in their growth and tolerance responses to ammonium and urea nutrition, while derived phenotypes seem markedly different from plants grown under nitrate supply. Plant responses to N sources are complex, ...
