An approach to textile dye removal using sawdust from Aspidosperma polyneuron
(International Journal of Environmental Studies, 2017-01-02) [Artigo]
The textile industry is responsible for discarding wastewater contaminated with dyes. The timber industry generates waste in the form of sawdust. The aim of the present study was to evaluate the adsorptive potential of ...
Biochemical properties and evaluation of washing performance in commercial detergent compatibility of two collagenolytic serine peptidases secreted by Aspergillus fischeri and Penicillium citrinum
(Preparative Biochemistry and Biotechnology, 2017-03-16) [Artigo]
Filamentous fungi secrete diverse peptidases with different biochemical properties, which is of considerable importance for application in various commercial sectors. In this study, we describe the isolation of two fungal ...
Cellulase production by trichosporon laibachii
(Orbital, 2017-07-01) [Artigo]
The ability of twenty-three yeast strains isolated from decayed wood and the fungus garden of attine ants to produce hemi- and cellulolytic hydrolases in a chemically defined medium was acessed. Xylanase, β-glucosidase and ...
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) production from biodiesel by-product and propionic acid by mutant strains of Pandoraea sp.
(Biotechnology Progress, 2017-07-01) [Artigo]
Pandoraea sp. MA03 wild type strain was subjected to UV mutation to obtain mutants unable to grow on propionic acid (PA) but still able to produce poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] from glycerol ...
Targeted therapies for the treatment of non-small-cell lung cancer: Monoclonal antibodies and biological inhibitors
(Human Vaccines and Immunotherapeutics, 2017-04-03) [Resenha]
The usual treatments for patients with non-small-cell lung cancer (NSCLC), such as advanced lung adenocarcinoma, are unspecific and aggressive, and include lung resection, radiotherapy and chemotherapy. Recently, treatment ...
Critical role of different immobilized biocatalysts of a given lipase in the selective ethanolysis of sardine oil
(Journal of Agricultural and Food Chemistry, 2017-01-01) [Artigo]
Different immobilized derivatives of two lipases were tested as catalysts of the synthesis of ethyl esters of omega-3 fatty acids during the ethanolysis of sardine oil in solvent-free systems at 25 °C. Lipases from Thermomyces ...
Environmentally Friendly Production of D(-) Lactic Acid by Sporolactobacillus nakayamae: Investigation of Fermentation Parameters and Fed-Batch Strategies
(International Journal of Microbiology, 2017-01-01) [Artigo]
The interest in the production of lactic acid has increased due to its wide range of applications. In the present study, the variables that affect fermentative D(-) lactic acid production were investigated: neutralizing ...
Metabolical shifts towards alternative BTEX biodegradation intermediates induced by perfluorinated compounds in firefighting foams
(Chemosphere, 2017-01-01) [Artigo]
The type and concentration of perfluorinated compounds (PFCs) can induce different types of enzymes and promote alternate patterns of BTEX transformation. However, it is not known how the presence of active fluorocarbon-degrading ...
Immobilization and Stabilization of Beta-Xylosidases from Penicillium janczewskii
(Applied Biochemistry and Biotechnology, 2017-05-01) [Artigo]
β-Xylosidases are critical for complete degradation of xylan, the second main constituent of plant cell walls. A minor β-xylosidase (BXYL II) from Penicillium janczewskii was purified by ammonium sulfate precipitation (30% ...
