Journal ArticleDOI
Production and characteristics comparison of crude β-glucosidases produced by microorganisms Thermoascus aurantiacus e Aureobasidium pullulans in agricultural wastes
Rodrigo Simões Ribeiro Leite,Heloiza Ferreira Alves-Prado,Hamilton Cabral,Fernando Carlos Pagnocca,Eleni Gomes,Roberto Da-Silva +5 more
TL;DR: Data confirm the high thermostability of crude β-glucosidase from A. pullulans ER-16, which was strongly inhibited by glucose, but ethanol significantly increased the activity of the enzyme from T. aurantiascus.
Journal ArticleDOI
Optimization of xylanase production by Bacillus circulans D1 in submerged fermentation using response surface methodology
Daniela Alonso Bocchini,Heloiza Ferreira Alves-Prado,L.C Baida,Inês Conceição Roberto,Eleni Gomes,R. J. da Silva +5 more
TL;DR: A second-order model was proposed to represent the enzymic activity as a function of xylan concentration and cultivation time, which predicted a xylanase activity of 19.1 U/ml.
Journal ArticleDOI
Screening and production study of microbial xylanase producers from Brazilian Cerrado.
Heloiza Ferreira Alves-Prado,Fabiana Carina Pavezzi,Rodrigo Simões Ribeiro Leite,Valéria Maia de Oliveira,Lara Durães Sette,Roberto Da-Silva +5 more
TL;DR: A microbial screening of xylanase producer was carried out in Brazilian Cerrado area in Selviria city, Mato Grosso do Sul State, Brazil and a bacterium Lysinibacillus sp.
Journal ArticleDOI
Production of Cyclodextrins by CGTase from Bacillus clausii Using Different Starches as Substrates
Heloiza Ferreira Alves-Prado,Andreia A.J. Carneiro,Fabiana Carina Pavezzi,Eleni Gomes,Maurício Boscolo,Célia Maria Landi Franco,R. J. da Silva +6 more
TL;DR: It was observed that the substrate sources influence the kind of CD obtained and that this CGTase displays a β-CGTase action, presenting a better conversion of soluble starch at 1.0%, of which 80% was converted in CDs.
Journal ArticleDOI
Purification and Characterization of Two Xylanases From Alkalophilic and Thermophilic Bacillus licheniformis 77-2
Valquiria B. Damiano,Richard J. Ward,Eleni Gomes,Heloiza Ferreira Alves-Prado,Roberto Santana da Silva +4 more
TL;DR: The alkalophilic bacteria Bacillus licheniformis 77-2 produces significant quantities of thermostable cellulase-free xylanases, and the predominant products of xylan hydrolysates indicated that these enzymes were endoxylanases.
