Uma visão sobre a estrutura, composição e biodegradação da madeira

Abstract: Recebido em 29/11/08; aceito em 8/4/09; publicado na web em 22/9/09 A VISION OF WOOD STRUCTURE, COMPOSITION AND BIODEGRADATION. Wood is the main raw material used in the pulp and paper industry. It is a material that presents heterogeneous structure and complex composition, which results in a relatively resistant material to the biodegradation process. In the present review, we attempted to summarize the structural characteristics of wood and describe the chemical nature of its major components to, afterwards,… Show more

“…The cell wall of each fiber is composed by several layers as followed: middle lamella, the thin primary wall, and the secondary wall, which is subdivided into external secondary wall (S1), middle secondary wall (S2) and internal secondary wall (S3). These layers are composed of microfibrils oriented into space in defined (angles) form, according to the each layer [9][10][11][12] .…”

“…According to Carvalho, Canilha, Ferraz and Milagres (2009), the white rot fungi are considered more efficient at wood biodegradation, since they are able to break down the three components of the plant cell wall (cellulose, hemicellulose, and lignin), whereas the brown rot fungi mainly degrade the polysaccharide fractions (cellulose and hemicellulose). Eaton and Hale (1993) argued that the natural resistance of wood is dependent on the access routes available to fungi and the chemical composition of the wood, with the latter being a characteristic that varies substantially among species and within the same tree.…”

“…O tema em questão tem sido abordado em várias revisões. [12][13][14][15] Por isso, alguns dos tópicos aqui apresentados serão referenciados para maior detalhamento em outros textos específicos já disponíveis na literatura. A abordagem fundamental da presente revisão mostra e discute como o entendimento dos mecanismos biodegradativos tem permitido desenvolver tecnologias inspiradas na ação dos fungos, mas muitas vezes simplificadas por meio de processos biomiméticos ou da ação isolada de enzimas sobre os materiais lignificados.…”
