Mecanismos envolvidos na biodegradação de materiais lignocelulósicos e aplicações tecnológicas correlatas

Abstract: Recebido em 9/11/10; aceito em 21/6/11; publicado na web em 8/8/11MECHANISMS INVOLVED IN THE BIODEGRADATION OF LIGNOCELLULOSIC MATERIALS AND RELATED TECHNOLOGICAL APPLICATIONS. The biodegradation of lignocellulosic materials is an important natural process because it is responsible for the carbon recycling. When induced under controlled conditions, this process can be used for technological applications such as biopulping, biobleaching of cellulosic pulps, pre-treatment for subsequent saccharification and cell… Show more

“…Many low molecular weight compounds have been identified in the cultivation of wood decomposing fungi. The mode of action of these compounds is to act directly on the plant cell wall or act as mediators of oxidative enzymes (Aguiar and Ferraz, 2011).…”

“…6 Lignin provides rigidity for stems to growth on land, and waterproofing vascular tissues for From the literature on fungal bioremediation, c.a. 30% focus on white-rot basidiomycetes -the main organisms able to extensively mineralize lignin, 5,13,14 and the ideal model for this is the white-rot fungus Phanerochaete chrysosporium. 13,15 It is more efficient than other fungi in degrading toxic or insoluble materials, because of its simultaneous oxidative and reductive mechanisms used in many different situations, according to the type and degree of contamination and area or effluent.…”
