1. 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

2. Molecular evolution and functional divergence of alcohol dehydrogenases in animals, fungi and plants
Abstract Alcohol dehydrogenases belong to the large superfamily of medium-chain dehydrogenases/reductases, which occur throughout the biological world and are involved with many important metabolic routes. We considered the phylogeny of 190 ADH sequences of animals, fungi, and plants. Non-class III Caenorhabditis elegans ADHs were seen closely related to tet

3. Potencial biotecnológico de fungos isolados do molusco Pugilina morio / Biotechnological potential of fungi isolated from shellfish Pugilina morio
This study aimed to investigate the biotechnological potential of fungi isolated from mollusk Pugilina morio. The development work began with the collection of mollusk P. morio in Barra do Ceará, a beach situated in Fortaleza-CE. Of the specimens collected were isolated three filamentous fungi, known as PM3, PM6 and PM9. The isolates were identified by mole

4. Cloning, expression and characterization of alcohol dehydrogenases in the silkworm Bombyx mori
Alcohol dehydrogenases (ADH) are a class of enzymes that catalyze the reversible oxidation of alcohols to corresponding aldehydes or ketones, by using either nicotinamide adenine dinucleotide (NAD) or nicotinamide adenine dinucleotide phosphate (NADP), as coenzymes. In this study, a short-chain ADH gene was identified in Bombyx mori by 5'-RACE PCR. This is t

5. Busca de álcool desidrogenases para aplicação em oxidação enantiosseletiva de álcoois / Searching for alcohol dehydrogenases for application in enantioselective oxidation of alcohols
Diante da biodiversidade de micro-organismos existentes na natureza e da necessidade de descobrir novos biocatalisadores para a síntese de bloco de construções quirais e de produtos químicos de alto valor agregado, o presente trabalho teve como objetivo realizar a bioprospeção de micro-organismos para aplicação em reações de oxidação enantiossele

6. Chemical Study of the antagonistic fungus Trichoderma harzianum / Estudo Químico do Fungo Antagonista Trichoderma harzianum
The chemical potential of Trichoderma harzianum, an antagonist fungus, was investigated. The fatty acid composition of this fungus grown in Czapeck, peptone and potato, with different carbon source (glycose and manitol) in the later medium, was determined after GC/MS analysis. The following fatty acids, as their methyl esters, were identified: hexadecanoic (

7. Conservação de sementes de mamão em função da presença da sarcotesta, teor de água das sementes e tipo de embalagem / Papaya (Carica papaya L.) seeds conservation in relation to sarcotesta presence, seed moisture content and kind of package
This work was carried out in the Laboratory of Seeds Analysis in the Department of Fitotecnia at Federal University of Viçosa from March 2004 to November 2005, in order to evaluate the effect of sarcotesta presence, seed moisture content and kind of packaging on papaya seed conservation during storage. Papaya seeds from Formosa group, hybrid Tainung 01, dri

8. Substrate specificity and stereospecificity of nicotinamide adenine dinucleotide-linked alcohol dehydrogenases from methanol-grown yeasts.
Nicotine adenine dinucleotide-linked primary alcohol dehydrogenase and a newly discovered secondary alcohol dehydrogenase coexist in most strains of methanol-grown yeasts. Alcohol dehydrogenases from methanol-grown yeasts oxidize (--)-2-butanol preferentially over its (+) enantiomorph. This is substantially different from alcohol dehydrogenases from bakers'

9. Geometric specificity of alcohol dehydrogenases and its potential for separation of trans and cis isomers of unsaturated aldehydes.
The geometric specificity of three different alcohol dehydrogenases (alcohol:NAD+ oxidoreductase, EC 1.1.1.1) (from yeast, from horse liver, and from Leuconostoc mesenteroides) in the reduction of trans- and cis-cinnamaldehydes has been investigated. All three enzymes display a remarkable trans specificity: they react with the trans isomer 7 to 647 times fas

10. Mammalian alcohol dehydrogenases of separate classes: intermediates between different enzymes and intraclass isozymes.
A comparison of the structure of class II human liver alcohol dehydrogenase (alcohol:NAD+ oxidoreductase, EC 1.1.1.1) (containing pi subunits) with those of the human class I isozymes (containing alpha, beta, and gamma subunits) reveals differences at about 40% of all positions. Variations are large for active-site regions, the segment around the second zinc

11. Alcohol and polyol dehydrogenases are both divided into two protein types, and structural properties cross-relate the different enzyme activities within each type.
Sorbitol dehydrogenase from sheep liver shows similarities to mammalian and yeast alcohol dehydrogenases. Comparisons based on peptides from segments of sorbitol dehydrogenase reveal that homologous regions with 38% identity include two ligands to the active site zinc atom in liver alcohol dehydrogenase, as well as further important residues. Similarities in

12. Comparison of Two Alcohol Dehydrogenases in the Fungus Rhizopus javanicus
Two alcohol dehydrogenases with different catalytic properties were separated from Rhizopus javanicus, and some of their immunological and molecular properties were compared.
