Produção, propriedades e aplicação de celulases na hidrólise de resíduos agroindustriais Production, properties and application of cellulases in the hydrolysis of agroindustrial residues

Autor: Aline Machado de Castro, Nei Pereira Jr

Publikováno v: Química Nova, Vol 33, Iss 1, Pp 181-188 (2010)

Cellulases have been intensively studied in the past few years, due to the interests in biofuels production from lignocellulosic materials, since they permit maintaining mild conditions during the conversion process. These enzymes can be produced by
