Separation and partitioning of Green Fluorescent Protein from Escherichia coli homogenate in poly(ethylene glycol)/sodium-poly(acrylate) aqueous two-phase systems
(ELSEVIER SCIENCE BV, 2008)
The partitioning of Green Fluorescent Protein (GFP) in poly(ethylene glycol)/Na-poly(acrylate) aqueous two-phase systems (PEG/NaPA-ATPS) has been investigated. The aqueous two-phase systems are formed by mixing the polymers ...
Acidity and Aluminum Speciation as Affected by Surface Liming in Tropical No-Till Soils
(SOIL SCI SOC AMER, 2010)
Aluminum toxicity is one of the major soil factors limiting root growth in acidic soils. Because of the increase in organic matter content in the upper few centimeters of soils under no-till systems (NTS), most Al in soil ...
Lignocellulosic polysaccharides and lignin degradation by wood decay fungi: the relevance of nonenzymatic Fenton-based reactions
(SPRINGER HEIDELBERG, 2011)
The brown rot fungus Wolfiporia cocos and the selective white rot fungus Perenniporia medulla-panis produce peptides and phenolate-derivative compounds as low molecular weight Fe(3+)-reductants. Phenolates were the major ...
Purification and Partial Characterization of an Exo-polygalacturonase from Paecilomyces variotii Liquid Cultures
(HUMANA PRESS INC, 2010)
An extracellular polygalacturonase (PG) produced from Paecilomyces variotii was purified to homogeneity through two chromatography steps using DEAE-Fractogel and Sephadex G-100. The molecular weight of P. variotii PG was ...
Transcript expression plasticity as a response to alternative larval host plants in the speciation process of corn and rice strains of Spodoptera frugiperda
(BioMed Central, 2017)
Abstract
Background
Our main purpose was to evaluate the expression of plastic and evolved genes involved in ecological speciation in the noctuid moth Spodoptera frugiperda, ...
Fructose ingestion impairs expression of genes involved in skeletal muscle’s adaptive response to aerobic exercise
(BioMed Central, 2017)
Abstract
Background
The inverse relationship between exercise capacity and its variation over time and both cardiovascular and all-cause mortality suggests the existence ...
Xylan extraction from pretreated sugarcane bagasse using alkaline and enzymatic approaches
(BioMed Central, 2017)
Abstract
Background
New biorefinery concepts are necessary to drive industrial use of lignocellulose biomass components. Xylan recovery before enzymatic hydrolysis of the ...
Chitosan-graft-poly(n-butyl acrylate) copolymer: Synthesis and characterization of a natural/synthetic hybrid material
(Elsevier, 2016-07)
Two chitosan polymers with different deacetylation degree and molecular weight were subjected to grafting reactions with the aim to enhance the properties of these bio-based materials. Specifically, n-butyl acrylate in ...
TdKT, a new killer toxin produced by Torulaspora delbrueckii effective against wine spoilage yeasts
(Elsevier Science, 2016-01)
Microbiological spoilage is a major concern throughout the wine industry, and control tools are limited. Thispaper addresses the identification and partial characterization of a new killer toxin from Torulaspora delbrueckiiwith ...
Lentiviral Gag assembly analyzed through the functional characterization of chimeric simian immunodeficiency viruses expressing different domains of the feline immunodeficiency virus capsid protein e114299
(Public Library of Science, 2014-12)
To gain insight into the functional relationship between the capsid (CA) domains of the Gag polyproteins of simian and feline immunodeficiency viruses (SIV and FIV, respectively), we constructed chimeric SIVs in which the ...
