Abstract

"PROCESSO DE POLPAçãO BIOMECâNICA DE EUCALIPTO". Em um processo para a preparação de lascas de madeira polpadas para fazer papel, a lasca de uma madeira dura tal como eucalipto, são inoculadas com cultura viva de um ou mais fungos de putrefação branca. Os fungos propagados através do corpo da lasca de madeira, atacando seletivamente a lignina da madeira sem prejudicar as fibras celulósicas. A polpação mecânica subseq³ente resulta na utilização reduzida de energia, resistência melhorada, e tempo de cozimento reduzido.
