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% ...

(Revista de Ciencias Farmaceuticas Basica e Aplicada, 2017-01-01) [Nota]
Yeasts from macroalgae and lichens that inhabit the South Shetland Islands, Antarctica
(Environmental Microbiology Reports, 2016-10-01) [Artigo]
Antarctic terrestrial ecosystems are largely dominated by lichens, while shallow coastal environments are mainly covered by macroalgae. The aim of this study was to isolate and to evaluate the diversity of yeasts in different ...
Cold-adapted enzymes produced by fungi from terrestrial and marine Antarctic environments
(Critical Reviews in Biotechnology, 2018-05-19) [Resenha]
Antarctica is the coldest, windiest, and driest continent on Earth. In this sense, microorganisms that inhabit Antarctica environments have to be adapted to harsh conditions. Fungal strains affiliated with Ascomycota and ...
A protein expression system for tandem affinity purification in Xanthomonas citri subsp citri
(Brazilian Journal Of Microbiology, 2016-04-01) [Artigo]
Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp. citri (Xac), is one of the most devastating diseases to affect citrus crops. There is no treatment for citrus canker; effective control against ...
Biodegradation and toxicity of byproducts from the treatment of landfill leachate with hydrotalcite
(Desalination And Water Treatment, 2018-06-01) [Artigo]
Despite the toxic potential of landfill leachate, some researchers have suggested its use as fertilizer. However, high leachate concentrations can have negative impacts on the environment. Hydrotalcite has been used for ...
Comparison of the adsorptive action of hydrotalcite, Moringa oleifera and activated carbon in the treatment of landfill leachate
(Desalination and Water Treatment, 2017-09-01) [Artigo]
Landfill leachate is formed by organic and inorganic toxic compounds. It has high salt concentration and pathogenic organisms that can cause environmental harm. Hydrotalcite, activated carbon and Moringa oleifera seeds ...
Chemical input reduction in the arabinoxylan and lignocellulose alkaline extraction and xylooligosaccharides production
(Bioresource Technology, 2017-01-01) [Artigo]
Lignocellulosic material breakdown by hydrolysis is an important step to open new perspectives for bioenergy and special foods production like prebiotic xylooligosaccharides. Improvement of lignocellulose and arabinoxylan ...
Improvement of Protein Bioavailability by Solid-State Fermentation of Babassu Mesocarp Flour and Cassava Leaves
(Waste and Biomass Valorization, 2018-04-01) [Artigo]
Purpose: The worldwide demand of food is continuously increasing along with its selling price. Higher food costs affect the access of poor communities to nutritious food, so become a priority problem to be solved, according ...
Structure and Biogenesis of Roussoellatide, a Dichlorinated Polyketide from the Marine-Derived Fungus Roussoella sp DLM33
(Organic Letters, 2015-11-06) [Artigo]
The structure of the fungal metabolite roussoellatide (1) has been established by spectroscopic and X-ray diffraction analyses. Results from feeding experiments with [1-C-13]acetate, [2-C-13]acetate, and [1,2-C-13]acetate ...
