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 ...
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% ...
