1. Carbon dioxide/methanol conversion cycle based on cascade enzymatic reactions supported on superparamagnetic nanoparticles
ABSTRACT The conversion of carbon dioxide into important industrial feedstock is a subject of growing interest in modern society. A possible way to achieve this goal is by carrying out the CO2/methanol cascade reaction, allowing the recycle of CO2 using either chemical catalysts or enzymes. Efficient and selective reactions can be performed by enzymes; howev

2. Aminotransferase and glutamate dehydrogenase activities in lactobacilli and streptococci
ABSTRACT Aminotransferases and glutamate dehydrogenase are two main types of enzymes involved in the initial steps of amino acid catabolism, which plays a key role in the cheese flavor development. In the present work, glutamate dehydrogenase and aminotransferase activities were screened in twenty one strains of lactic acid bacteria of dairy interest, either

3. Reducing lactate secretion by ldhA Deletion in L-glutamate- producing strain Corynebacterium glutamicum GDK-9
L-lactate is one of main byproducts excreted in to the fermentation medium. To improve L-glutamate production and reduce L-lactate accumulation, L-lactate dehydrogenase-encoding gene ldhA was knocked out from L-glutamate producing strain Corynebacterium glutamicum GDK-9, designated GDK-9ΔldhA. GDK-9ΔldhA produced approximately 10.1% more L-glutamate than t

4. Intestinal parasites and genotyping of Giardia duodenalis in children: first report of genotype B in isolates from human clinical samples in Mexico
Giardia duodenalis is one of the most prevalent enteroparasites in children. This parasite produces several clinical manifestations. The aim of this study was to determine the prevalence of genotypes of G. duodenalis causing infection in a region of southeastern Mexico. G. duodenalis cysts were isolated (33/429) from stool samples of children and molecular

5. Molecular identification of Giardia duodenalis in Ecuador by polymerase chain reaction-restriction fragment length polymorphism
The aim of this study was to determine the genetic diversity of Giardia duodenalis present in a human population living in a northern Ecuadorian rain forest. All Giardia positive samples (based on an ELISA assay) were analysed using a semi-nested polymerase chain reaction-restriction fragment length polymorphism assay that targets the glutamate dehydrogenase

6. Identificação molecular dos isolados de Giardia duodenalis em crianças procedentes dos municípios de Araguari e Uberlândia
Giardia duodenalis is a parasite of several mammalian species, including humans, with a worldwide distribution. It is associated with diarrhea and nutritional disorders, especially in children. Molecular characterization of the parasite is crucial to identify assemblages/sub-assemblages related to infection, and its association with clinical manifestations.

7. Hepatoprotective efficacy of Hypnea muciformis ethanolic extract on CCl4 induced toxicity in rats
The ethanolic extract of Hypnea muciformis (red algae) was tested for hepatoprotective activity against experimentally induced liver damage by Carbon tetrachloride (CCl4) in male albino rats. The levels of serum enzymatic and biochemical parameters such as serum glutamate oxaloacetate transaminase (SGOT), Serum glutamate pyruvate transaminase (SGPT), alkalin

8. Antidiabetic activity of Pseudarthria viscida aqueous root extract in neonatal streptozotocin-induced NIDDM rats
The antidiabetic activity of the aqueous root extract of Pseudarthria viscida (L.) Wight & Arn., Fabaceae, was investigated in normal and neonatal streptozotocin (n2-STZ)-induced non insulin-dependent diabetes mellitus (NIDDM) rats and compared with glibenclamide as a reference standard. Two different doses (250 and 500 mg/kg) of the extract were administere

9. Metabolic networks and bioenergetics of Aurantiochytrium sp. B-072 during storage lipid formation
Baffled shake flask cultivation of Aurantiochytrium sp. B-072 was carried out at in a glucose-monosodium glutamate mineral medium at different C/N-ratios (30-165) with glucose fixed at 90 g/L. With increasing C/N-ratio, a modest increase in lipid content (60 to 73 % w/w) was observed whereas fat-free biomass decreased but overall biomass showed little variat

10. In vitro and in situ activity of carboxymethyl cellulase and glutamate dehydrogenase according to supplementation with different nitrogenous compounds
Two experiments were carried out to evaluate the effect of supplementation with different nitrogenous compounds on the activities of carboxymethil cellulase (CMCase) and glutamate dehydrogenase (GDH). In the first experiment, four treatments were evaluated in vitro: cellulose, cellulose with casein, cellulose with urea, and cellulose with casamino acids. Aft

11. Foliar nitrogen and changes in free amino acid composition of Solanum lycopersicum under cadmium toxicity: kinetics of 15NH4+
Glutamate metabolism and amino acid translocation were investigated in the control and cadmium stressed shoots of tomato (Solanum lycopersicum - 63/5 F1), using (15N) ammonium and (15N) glutamate tracers. Regardless of organ type, [15N] ammonium assimilation occurred via glutamine synthetase (EC 6.3.1.2), in the control and stressed plants, and it did not de

12. Caracterização molecular e funcional da enzina glutamato desidrogenase (GDH) em Ilhotas de ratos submetidos à restrição protéica e suplementados com leucina / Molecular and functional characterization of glutamate dehydrogenase (GDH) enzyme in irats islets submitted to protein restriction and supplemented with leucine
A glutamato desidrogenase (GDH) é uma enzima mitochondrial que cataliza a reação reversível de glutamato a ?-cetoglutarato. Nas ilhotas pancreáticas, está associada com a secreção de insulina por aumentar a concentração de ATP. Ratos alimentados com dieta hipoprotéica apresentam secreção de insulina diminuída. A suplementação com leucina (LEU
