Journal ArticleDOI
Estimating the chemical composition of biodegraded pine and eucalyptus wood by DRIFT spectroscopy and multivariate analysis
TL;DR: In this paper, Fourier transformed infra-red (FTIR) was evaluated as an analytical tool for monitoring wood biodegradation, and multivariate analysis was applied to correlate chemical composition in wood samples with the FTIR spectral data.
Journal ArticleDOI
A study on the pretreatment of a sugarcane bagasse sample with dilute sulfuric acid
Larissa Canilha,Victor Tabosa de Oliveira Santos,George Jackson de Moraes Rocha,João B. Almeida e Silva,Marco Giulietti,Silvio Silvério da Silva,Maria das Graças de Almeida Felipe,André Ferraz,Adriane M. F. Milagres,Walter Carvalho +9 more
TL;DR: In this article, a 2(3) central composite full factorial design was used to study the pretreatment of a sugarcane bagasse sample obtained from a local sugar-alcohol mill.
Journal ArticleDOI
Chemical composition and enzymatic digestibility of sugarcane clones selected for varied lignin content
Fernando Masarin,Daniela de Borba Gurpilhares,David Cf Baffa,Márcio Hp Barbosa,Walter Carvalho,André Ferraz,A.M.F. Milagres +6 more
TL;DR: Some of the experimental sugarcane hybrids did have the combined characteristics of high biomass and high sucrose production with low lignin content, but required less delignification to reach higher efficiencies of cellulose conversion during the enzymatic treatment.
Journal ArticleDOI
Enhancement of cellulose hydrolysis in sugarcane bagasse by the selective removal of lignin with sodium chlorite
TL;DR: In this article, the objective was to selectively remove lignin from sugarcane bagasse with sodium chlorite/acetic acid to produce model substrates with lower levels of this component.
Journal ArticleDOI
Extraction and determination of enzymes produced by Ceriporiopsis subvermispora during biopulping of Pinus taeda wood chips
TL;DR: In this work, enzymes produced during biopulping were extracted and determined by using a series of substrates and Manganese-dependent peroxidases (MnP) predominated over laccases, which were of minor significance.
