Produção de celulases e xilanases por fermentação em estado sólido usando palha de carnaúba pré-tratada e avaliação da reutilização do resíduo
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Química, 2017-11-06)
Native to Brazil, the Carnaúba palm (Copernicia prunifera) has been used in the production of wax from its leaf. After extraction of the wax, a considerable amount cellulose-rich fibers is generated which can be used as a ...
Simultaneous saccharification and fermentation process of different cellulosic substrates using a recombinant Saccharomyces cerevisiae harbouring the β-glucosidase gene
(Pontificia Universidad Católica de Valparaíso, 2010)
Utilização de resíduo lignocelulósico na obtenção de chapa de madeira aglomerada homogênea e compósito reforçado com fibra de vidro-E
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2008-07-10)
This research is about the use of the coconut´s endocarp (nucifera linn) and the waste of derivatives of wood and furniture as raw material to technological use. In that sense, the lignocellulosic ...
Produção de bioetanol utilizando cascas de banana, maracujá e coco verde por co-fermentação de Zymomonas mobilis e Pachysolen tannophilus
(Universidade Estadual Paulista (Unesp), 2017-03-24)
As crises no fornecimento de petróleo, a possibilidade de sua escassez, instabilidade dos preços e, principalmente, os efeitos negativos ao meio ambiente, aumentaram, nos últimos anos, o interesse pela procura de fontes ...
Optimization of the hydrolysis of lignocellulosic residues by using radial basis functions modeling and particle swarm optimization
(Elsevier Science Sa, 2013-10)
The concentrations of glucose and total reducing sugars obtained by chemical hydrolysis of three different lignocellulosic feedstocks were maximized. Two response surface methodologies were applied to model the amount of ...
Significant factors selection in the chemical and enzymatic hydrolysis of lignocellulosic residues by a genetic algorithm analysis and comparison with the standard Plackett-Burman methodology
(Elsevier, 2011-11)
A comparison between the classic Plackett-Burman design (PB) ANOVA analysis and a genetic algorithm (GA) approach to identify significant factors have been carried out. This comparison was made by applying both analyses ...

Challenges in the production of second-generation organic acids (potential monomers for application in biopolymers)
(2021-06-01)
Bio-based plastics represent only 1% of world production, while 98% are plastics of fossil origin. This shows how far we are from an ecologically correct scenario we are, and how much more needs to be done to develop ...
A new heteroscedastic regression to analyze mass loss of wood in civil construction in Brazil
(2021-01-01)
A heteroscedastic regression based on the odd log-logistic Marshall–Olkin normal (OLLMON) distribution is defined by extending previous models. Some structural properties of this distribution are presented. The estimation ...
