1. Enzyme Detection and Metabolic Process Tracking of Ethanol Fermentation by a Natural Alginate Fermentation Strain
ABSTRACT Alginate is a major component of brown algae, but it cannot be utilized for ethanol fermentation by industrial microorganisms. A natural alginate degrading and ethanol producing strain was obtained in our previous research. However, the research on the ethanol metabolism process of the natural alginate fermentation strain is lacked. In this research

2. The potential of the newly isolated thermotolerant yeast Pichia kudriavzevii RZ8-1 for high-temperature ethanol production
Abstract High potential, thermotolerant, ethanol-producing yeasts were successfully isolated in this study. Based on molecular identification and phylogenetic analysis, the isolated thermotolerant yeasts were clustered in the genera of Pichia kudriavzevii, Candida tropicalis, Candida orthopsilosis, Candida glabrata and Kodamea ohmeri. A comparative study of

3. Bioelectrooxidation of Ethanol Using NAD-Dependent Alcohol Dehydrogenase on Oxidized Flexible Carbon Fiber Arrays
Hierarchical 3-dimensional flexible carbon fiber (FCF) array is a candidate as flexible electrode for enzyme electrochemistry, with interesting properties for application in enzymatic biofuel cell and implantable biosensors. Here, we show the fabrication of oxidized FCF electrode (FCFO) based on chemical surface treatment, a wet oxidation method by using per

4. Waterlogging-induced changes in fermentative metabolism in roots and nodules of soybean genotypes
Waterlogging blocks the oxygen supply to the root system which inhibits respiration, and greatly reduces the energy status of cells that affect important metabolic processes. This study evaluated fermentative metabolism and carbohydrate contents in the root system of two soybean (Glycine max L. Merril) genotypes under hypoxic and post-hypoxic conditions. Nod

5. Avaliação de polimorfismos em genes de metabolismo do etanol e gene de reparo do DNA em pacientes portadores de câncer de boca / Evaluation of polymorphisms in genes of ethanol metabolism and DNA repair gene in patients with oral cancer
O carcinoma epidermóide é uma neoplasia que pode ter origem do revestimento mucoso de vários sítios das vias aerodigestivas superiores, sendo a língua o sítio primário com maior incidência. Entre os fatores de risco para a doença estão a idade, as mutações genômicas, o hábito tabagista e principalmente o consumo de etanol. O etanol é considera

6. Ação de absorvedores de etileno e de oxigênio na conservação pós-colheita de morango / Action of ethylene and oxygen absorbers on postharvest strawberry conservation
The present work aimed to study the influence of the PVC (polyvinyl chloride) film of different concentrations of KMnO4 (ethylene absorbent) and the oxygen absorber sachet (O-Buster) on the quality and postharvest conservation of Oso Grande strawberries. In order to achieve this physical-chemical, enzymatic and visual analyses were performed every 2 days on

7. Production of functional killer protein in batch cultures upon a shift from aerobic to anaerobic conditions
The aim of this work was to study the production of functional protein in yeast culture. The cells of Saccharomyces cerevisiae Embrapa 1B (K+R+) killed a strain of Saccharomyces cerevisiae Embrapa 26B (K-R-)in grape must and YEPD media. The lethal effect of toxin-containing supernatant and the effect of aeration upon functional killer production and the corr

8. Evaluation of activated vegetal charcoal and vegetal polymer on the detoxification of the sugarcane hemicellulosic hydrolysate for biotechnological production of xylitol / Avaliação do carvão vegetal ativado e polímero vegetal na destoxificação do hidrolisado hemicelulósico de bagaço de cana-de-açúcar para a produção biotecnológica de xilitol
The increasing search for ethanol fuel in order to reduce the dependence and to promote the substitution of fossil fuels will contribute to higher accumulation of sugarcane bagasse in the environment. This biomass that in Brazil is a by-product of the sugar-alcohol mills, although it has been used for the generation of energy in the sugar and alcohol product

9. Genetic polymorphism of alcohol-metabolizing enzyme and alcohol dependence in Polish men
Alcohol dependence poses a serious medical and sociological problem. It is influenced by multiple environmental and genetic factors, which may determine differences in alcohol metabolism. Genetic polymorphism of the enzymes involved in alcohol metabolism is highly ethnically and race dependent. The purpose of this study was to investigate the differences, if

10. Alcohol dehydrogenase activities and ethanol tolerance in Anastrepha (Diptera, Tephritidae) fruit-fly species and their hybrids
The ADH (alcohol dehydrogenase) system is one of the earliest known models of molecular evolution, and is still the most studied in Drosophila. Herein, we studied this model in the genus Anastrepha (Diptera, Tephritidae). Due to the remarkable advantages it presents, it is possible to cross species with different Adh genotypes and with different phenotype tr

11. Metabolismo de lactose em Kluyveromyces marxianus UFV-3 e Kluyveromyces lactis JA6 / Metabolism of lactose by Kluyveromyces marxianus UFV-3 and Kluyveromyces lactis JA6
The fermentative metabolism of lactose in Kluyveromyces marxianus UFV-3 was compared to the Kluyveromyces lactis JA6 under aerobic and hypoxia through the analysis of kinetics of growth, consumption of substrate, production of ethanol and formation of biomass, depending on the concentration of lactose. It was determinated the gene expression and activity of

12. The combination of atorvastatin and ethanol is not more hepatotoxic to rats than the administration of each drug alone
Animal studies and premarketing clinical trials have revealed hepatotoxicity of statins, primarily minor elevations in serum alanine aminotransferase levels. The combined chronic use of medicines and eventual ethanol abuse are common and may present a synergistic action regarding liver injury. Our objective was to study the effect of the chronic use of atorv
