Isolamento e identificação de microrganismos produtores de hidrogênio a partir do glicerol residual
(2015-02-12)
One of the major challenges for the coming years is to develop alternative forms of production for sustainable energy. The biodiesel is positioning itself as an option for the replacement of fossil fuels. Its production ...
Produção e caracterização parcial de pectinases de Aspergillus niger LB-02-SF obtidas em processo submerso
(2016-05-12)
The production of pectinases by Aspergillus niger LB-02-SF was carried out in submerged process, aiming to evaluate process conditions and to characterize and utilize the produced enzymes. The process conditions evaluated ...
Atividade biológica de extratos de Piper aduncum e Piper hispidinervum sobre Anticarsia gemmatalis e Spodoptera frugiperda
(2016-05-24)
Piper aduncum found naturally in the Amazon and in southeastern Brazil and Piper hispidinervum Acre native are known for their secondary metabolites with biological activity on insects. Among the main insect pests associated ...
Produção de poligalacturonases por Aspergillus niger em processo em estado sólido em biorreator com dupla superfície
(2014-05-15)
In this work, the production of enzymes endo and exo-polygalacturonase (endo and exo-PG) by the strain Aspergillus niger t0005/007-2, in solid medium in a double-surface bioreactor, was studied. The following operational ...
Compostos de coordenação do ácido valproico e metais de transição como medicamentos
(2015-02-12)
Valproic acid (VPA) is a first-line drug in the treatment of seizures in general, but the side effects from high doses produce liver damage by metabolism. VPA has high affinity for transition metals and produces chemically ...
Emprego do glicerol como fonte de carbono na produção fermentativa de 2,3-Butanodiol por Enterobacter aerogenes ATCC 13048
(2015-02-24)
In this work, the use of glycerol as carbon source for cell growth and 2,3-butanediol/acetoin production in the in cultivation of Enterobacter aerogenes ATTT 13048 was studied. The influence of initial substrate concentration ...
Produção de 2,3-Butanodiol a partir de glicerol por klebsiella oxytoca ATCC 8724
(2015-02-24)
Glycerol is a by-product of biodiesel production, which accounts for approximately 10% of the biofuel. Since a large volume of it is formed in industry, glycerol could be used as a substrate to obtain other compounds, such ...
