Produção de celulases e xilanases por Penicillium echinulatum em biorreator com agitação mecânica
(2014-06-11)
Cellulases and xylanases are enzymes that hydrolyze cellulose and xylan respectively, which are
found in lignocellulosic residues. Although the applicability of these enzymes in the ethanol
production has been the subject ...
Uso do sistema enzimático de Zymomonas mobilis para a produção de ácidos maltobiônico e lactobiônico
(2017-09-18)
Maltobionic and lactobionic acid are formed through the oxidation of maltose and lactose, whereas sorbitol is formed in equimolar amount through the reduction of fructose, by means of the catalytic action of the glucose-fructose ...
Avaliação da produção de pectinases por Aspergillus oryzae IPT-301 em processo submerso
(2014-06-16)
The cultivation of Aspergillus oryzae IPT-301 in liquid medium was studied to assess the
influence of pH and oxygen supply on the fungal growth and the formation of pectinases. A growthlimiting
medium was defined with ...
Produção de celulases e xilanases por Penicillium echinulatum em processo submerso utilizando biorreatores com agitação mecânica e airlift de circulação interna
(2014-05-29)
Cellulolytic enzymes have many uses, particularly in the food, textile, and paper industries. However, their major potential use is in the hydrolysis of cellulose a component of lignocellulosic residues for ethanol ...
Enzimas pectinolíticas : seleção de linhagens fúngicas produtoras, caracterização e aplicação em processos da indústria de alimentos
(2014-06-02)
In this work, fungus samples isolated from decomposing vegetables were tested with respect to their capacity of producing pectinases to be applied to the enzymatic treatment of apple and bilberry juices. Taking in account ...
Avaliação da técnica de eletrodiálise para a separação de ácido lactobiônico produzido por via biotecnológica
(2014-05-14)
Glicose-fructose oxidoreductase (GFOR) and glicono-d-lactonase (GL) enzymes are present in Zymomonas mobilis bacteria cells. These enzymes are capable to catalyze lactobionic acid (AL) formation (or formation of its ...
Estratégias para incremento das atividades de celulases e xilanases por penicillium echinulatum SIM29 em cultivo submerso
(2017-07-14)
Cellulases and xylanases are enzymes with ability to hydrolyze cellulose and hemicellulose, respectively, from plant biomass, releasing fermentable sugars that can be converted into various biotechnological products. Among ...
Promoter sequences classification through the analysis of enthalpy, entropy, stability abd base-pair stacking values
(2019-04-18)
Promoter sequence recognition by RNAp enzyme is a key step in gene transcription. Its location is found in a few base pairs before the coding region. An in-depth study of promoters sequences role might provide an enhanced ...
Estratégias de reuso de micélio de Penicillium echinulatum e de Trichoderma reesei em cultivo sólido para a produção de celulases e xilanases
(2021-12-02)
The usage of lignocellulosic biomass for second-generation ethanol production is the target of many studies in Biotechnology. One of the bottlenecks to the wide application of this technology lays on the difficulty of ...
