(Sociedad Entomológica Argentina, 2018)Se cita por primera vez en Mendoza, Argentina a Drosophila suzukii (Matsumura) asociada al cultivo de zarzamora variedad Prime-Ark (Rubus L. subgen. Rubus Watson) y se amplía el límite oeste de distribución de la misma en el país -
Probabilistic model for the spoilage wine yeast Dekkera bruxellensis as a function of pH, ethanol and free SO2 using time as a dummy variable
(Elsevier, 2014-01-17)The present study uses a probabilistic model to determine the growth/no growth interfaces of the spoilage wine yeast Dekkera bruxellensis CH29 as a function of ethanol (10–15%, v/v), pH (3.4–4.0) and free SO2 (0–50 mg/l) ... -
Producción orgánica de uva en Mendoza, Argentina: tipos de productores, caracterización técnica y económica = Organic grape production in Mendoza, Argentina: types of winegrowers, technical and economic characterization
(Facultad de Ciencias Económicas, Universidad Nacional de Cuyo, 2018-06-18)En este trabajo se analiza la producción de uva declarada orgánica o agroecológica en Mendoza, Argentina, con el objetivo de conocer la estructura y funcionamiento de estos sistemas de producción para evaluar y proponer ... -
Prospection and identification of traditional-heritage Peruvian grapevine cultivars (Vitis vinifera L.) from Ica and Cañete valleys
(Julius Kühn-Institut Institute for Grapevine Breeding Geilweilerhof, 2022-06-03)Interest in ancient and autochthonous cultivars has increased in recent years since they are directly related to the historical and cultural values of a region. Ica and Cañete valleys (Peru) have a long history of grapevine ... -
Pruning after budburst delays phenology and affects yield components, crop coefficient and total evapotranspiration in Vitis vinífera L. cv. ‘Malbec’ in Mendoza, Argentina
(Elsevier, 2022-02-23)Late pruning is a field technique that has recently been proposed to mitigate the advance in phenology produced by global warming. However, contrasting effects have been observed depending on the cultivar and the date of ... -
Reduction of Zygosaccharomyces rouxii Population in Concentrated Grape Juices by Thermal Pasteurization and Hydrostatic High Pressure Processing
(Springer, 2019-02)Zygosaccharomyces rouxii is the most frequent spoilage yeast species detected in concentrated grape juice. In order to reduce Z. rouxii populations and consequently extend the microbiological shelf life of this product, ... -
Regulated Deficit Irrigation Alters Anthocyanins, Tannins and Sensory Properties of Cabernet Sauvignon Grapes and Wines
(2015-04)Four regulated deficit irrigation (RDI) regimes were applied to Cabernet Sauvignon grapes, which were analyzed for phenolics and also made into wine over three consecutive growing seasons. Relative to an industry standard ... -
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 ... -
Relationships among Gene Expression and Anthocyanin Composition of Malbec Grapevine Clones
(2014-07)Anthocyanin profiles are commonly used for grapevine cultivar identification because it is currently accepted that this trait is closely related to their genetic characteristics. Nevertheless, the extent of the variation ... -
Review: critical appraisal of methods to investigate the effect of temperature on grapevine berry composition
(Wiley, 2015-02)The grapevine is an economically important crop and a model species of long‐lived perennials widely used in bioclimatic studies. Ambient temperature modulates berry composition, hence the significant research effort in ... -
Rootstocks increase grapevine tolerance to NaCl through ion compartmentalization and exclusion
(Springer, 2020-09)The productivity of Vitis vinifera L. is limited by salinity, especially under water and drainage deficits, and could aggravate with climate change. The use of tolerant rootstocks is a strategy against salinity that helps ... -
Screening of Saccharomyces strains for the capacity to produce desirable fermentative compounds under the influence of different nitrogen sources in synthetic wine fermentations
(Elsevier, 2021-02)A collection of 33 Saccharomyces yeasts were used for wine fermentation with a sole nitrogen source: ammonium and four individual aroma-inducing amino acids. The fermentation performance and chemical wine composition were ... -
Selection of indigenous Saccharomyces cerevisiae strains to ferment red musts at low temperature
(2012-03)The aim of this work was to select native Saccharomyces cerevisiae strains to conduct the alcoholic fermentation of red must at low temperature (15°C), thus producing volatile compounds that enhance the aromatic profile ... -
Selection of Native Non-Saccharomyces Yeasts with Biocontrol Activity against Spoilage Yeasts in Order to Produce Healthy Regional Wines
(MDPI, 2019-07)Two major spoilage yeasts in the wine industry, Brettanomyces bruxellensis and Zygosaccharomyces rouxii, produce off-flavors and gas, causing considerable economic losses. Traditionally, SO2 has been used in winemaking to ... -
Selection of non-Saccharomyces yeasts to be used in grape musts with high alcoholic potential: A strategy to obtain wine with reduced etanol content
(2017)Ethanol content of wine has increased over the last decades as consequence of searching phenolic maturity, requiring increased grape maturity. This may result in the production of wines with excessive alcohol levels ... -
