AHAS Trp574Leu substitution in Raphanus sativus L.: screening, enzyme activity and fitness cost
(2018-07)BACKGROUND: Feral radish (Raphanus sativus L.) is a problematic weed that has become resistant to acetohydroxyacid synthase (AHAS) inhibitor herbicides due to the Trp574Leu mutation. An AHAS gene mutation that causes ... -
Characterization of Cellulolytic Activities of Environmental Bacterial Consortia from an Argentinian Native Forest
(Springer, 2013-08)Cellulolytic activities of three bacterial consortia derived from a forest soil sample from Chaco region, Argentina, were characterized. The phylogenetic analysis of consortia revealed two main highly supported groups ... -
Effect of cover crops on microbial community structure and related enzyme activities and macronutrient availability
(2016)Continuous monoculture in major agricultural regions has been characterized by the loss of fertility, increased soil erosion and surface runoff. Thus, the inclusion of cover crops (CC) is a promising option aimed at better ... -
Enzymatic activities produced by mixed Saccharomyces and non-Saccharomyces cultures : relationship with wine volatile composition
(2015-11)During certain wine fermentation processes, yeasts, and mainly non-Saccharomyces strains, produce and secrete enzymes such as b-glucosidases, proteases, pectinases, xylanases and amylases. The effects of enzyme activity ... -
Microbiological Diversity and Associated Enzymatic Activities in Honey and Pollen from Stingless Bees from Northern Argentina
(MDPI, 2024-03)Honey and pollen from Tetragonisca fiebrigi and Scaptotrigona jujuyensis, stingless bees from northern Argentina, presented a particular microbiological profile and associated enzymatic activities. The cultured bacteria ... -
Molecular identification of a cyclodextrin glycosyltransferase-producing microorganism and phylogenetic assessment of enzymatic activities
(Academia Brasileira de Ciências, 2019-10)Cyclodextrin glycosyltransferases (CGTases) are important enzymes in the biotechnology field because they catalyze starch conversion into cyclodextrins and linear oligosaccharides, which are used in food, pharmaceutical ... -
Mollisol : biological characterization under Zero Tillage with different crops sequences
(2017-01)Zero tillage practices have a direct effect on soil microbial communities modifying soil productivity and sustainability. The crop sequences used can change the aforementioned properties, too. In this study, we evaluated ... -
Multi-enzyme production by pure and mixed cultures of Saccharomyces and non-Saccharomyces yeasts during wine fermentation
(Elsevier, 2012-04-02)Saccharomyces and non-Saccharomyces yeasts release enzymes that are able to transform neutral compounds of grape berries into active aromatic compounds, a process that enhances the sensory attributes of wines. So far, there ... -
Relation between coumarate decarboxylase and vinylphenol reductase activity with regard to the production of volatile phenols by native Dekkera bruxellensis strains under ‘wine-like’ conditions
(2015-08)Dekkera/Brettanomyces bruxellensis is considered a major cause of wine spoilage, and 4-ethylphenol and 4-ethylguaiacol are the most abundant off-aromas produced by this species. They are produced by decarboxylation of the ... -
Sensibilidad de indicadores biológicos edáficos en un Argiudol de la Región Pampeana Argentina
(Sociedad Española de la Ciencia del Suelo, 2015)Mantener la calidad de los suelos y la productividad de los cultivos es un desafío importante para la agricultura moderna. Prácticas de manejo que tiendan a incrementar el contenido de carbono del suelo y a la vez favorecer ...
