The latter corresponds to the interior of a spherical shell, where the dimensions of the rods are comparable to the radius of curvature of the container: they have to accomodate to fill the available space, leadin...
Among the structural polymers present in the plant cell wall, pectin is the main component of the middle lamella. This heterogeneous polysaccharide has an α-1,4 galacturonic acid backbone, which can be broken by the enzymatic action of pectinases, such as exo-polygalacturonases, that sequentially cleave pectin from the non-reducing ends, releasing mono or di-galacturonic acid residues. Constant demand for pectinases that better suit industrial requirements has motivated identification and characterization of novel enzymes from diverse sources. Bacillus licheniformis has been used as an important source for bioprospection of several industrial biomolecules, such as surfactants and enzymes, including pectate lyases. Here we cloned, expressed, purified, and biochemically and structurally characterized an exo-polygalacturonase from B.

A substance may occur in different states of aggregation. At high temperatures and low pressures it occurs in gaseous form. At low temperatures and high pressures, it occurs in solid form.
La justicia argentina ha acusado here a miembros do Hezbolá y al gobierno iranà por participar en el ataque a un centro judÃeste en 1994, donde murieron 85 personas. Pero la medida llega también en un momento en de que Estados Unidos Procura aliados para ejercer presión Acerca Irán.
Here we study the kinetics of chemical reactions from the stochastic point of view. We consider a system comprised by a vessel inside which several chemical species transform into each other according to certain chemical reactions. The thermochemical process caused by the chemical reactions is understood as a stochastic proces...
A crystalline solid has as a fundamental property the ordered structure of its atoms. This structure consists of an array of sites forming a regular three-dimensional periodic lattice.

Endoglucanases are key enzymes in the degradation of cellulose, the get more info most abundant polymer on Earth. The aim of this work was to perform the biochemical and biophysical characterization of CelE2, a soil metagenome derived endoglucanase. CelE2 harbors a conserved domain from glycoside hydrolase family 5 (GH5) and a C-terminal domain with identity to Calx-beta domains. The recombinant CelE2 displayed preference for hydrolysis of oat beta-glucan, followed by lichenan and carboxymethyl cellulose. Optimum values of enzymatic activity were observed at 45 °C and pH 5.3, and Mario de Oliveira CelE2 exhibited considerable thermal stability at 40 °C for up to 360 minutes. Regarding the cleavage pattern on polysaccharides, the release of oligosaccharides with a wide degree of polymerization indicated a characteristic of endoglucanase activity.
Lignin is a macromolecule frequently obtained as residue during technological processing of biomass. Modifications in chemical structure of lignin generate valuable products with particular and unique characteristics. One of the available methods for modification of industrial lignin is oxidation Mario de Oliveira by hydrogen peroxide. In this work, we conducted systematic studies of the oxidation process that were carried out at various pH and oxidizing agent concentrations. Biophysical, biochemical, structural properties of the oxidized lignin were analyzed by UV spectrophotometry, Fourier transform infrared spectroscopy, scanning electron microscopy and small angle X-ray scattering.
In this chapter we study systems governed by master equations and defined in a lattice. To each site of lattice there is a stochastic variable that takes only two values which we choose to be + 1 daniel dantas facebook or − 1.
