Análisis transcriptómico de la respuesta de S. cerevisiae durante fermentaciones enlentecidas causadas por shock térmico
(Asociación Argentina de Tecnólogos Alimentarios (AATA), 2023-10)Las fermentaciones detenidas o enlentecidas constituyen un problema frecuente que afecta la industria vitivinícola, siendo los incrementos bruscos de la temperatura una causa poco estudiada. En un estudio previo evaluamos ... -
Co-fermentation of Syrah with various additions of Viognier: Effect on colour and phenolics during winemaking and bottle ageing
(2013-10)The impetus for the study described in this article was to assess the effect of co-fermentation of Syrah and Viognier in the phenolic chemistry and colour stability of the resulting wines and to document potential benefits ... -
Combination of pre-fermentative and fermentative strategies to produce Malbec wines of lower alcohol and pH, with high chemical and sensory quality
(International Viticulture and Enology Society (IVES), 2020)The climatic conditions in some wine regions imply in many cases the important delay in the harvest date to achieve an appropriate phenolic maturity in red grape varieties, leading to wines with high pH and alcohol content. ... -

Efecto de la inoculación de levaduras seleccionadas y de la concentración de nitrógeno fácilmente asimilable sobre las características de hidromieles
(Asociación Argentina de Microbiología, 2021-10-21)Argentina es el quinto productor y el segundo exportador mundial de miel a granel. Un producto atractivo para el agregado de valor en miel es la elaboración de hidromiel. Esta bebida se obtiene mediante la fermentación ... -
Effect of low temperature fermentation on the yeast-derived volatile aroma composition and sensory profile in Merlot wines
(Elsevier, 2021-02)Different winemaking practices have been tried to improve wine quality and differentiate wine styles. Low temperature fermentation has been proposed to enhance the aroma profile in young red wines. The aim of this work was ... -
Effect of transient thermal shocks on alcoholic fermentation performance
(Elsevier, 2019-10)Stuck and sluggish fermentations are among the main problems in winemaking industry leading to important economic losses. Several factors have been described as causes of stuck and sluggish fermentations, being exposure ... -
Effects of maceration length after prefermentative cold soak: Detailed chromatic, phenolic and sensory composition of cabernet sauvignon, malbec and merlot wines
(Elsevier, 2021-09-21)Cabernet Sauvignon, Malbec and Merlot grapes were processed with prefermentative cold soak (CS) for 5 days followed by a short maceration time of 5 days (CS + 5d), or a long maceration time of 10 days (CS + 10d). CS did ... -
Evaluation of behaviour of Lachancea thermotolerans biocontrol agents on grape fermentations
(Society for Applied Microbiology, 2018-07)Previous researches have showed that Lachancea thermotolerans strains RCKT4 and RCKT5 inhibited the growth of Aspergillus. However, currently, there are no data on their nutritional preferences, as a possible substrate ... -
Genome-wide gene expression of a natural hybrid between Saccharomyces cerevisiae and S. kudriavzevii under enological conditions
(Elsevier, 2012-07-16)The species Saccharomyces cerevisiae plays a predominant role in the wine making process. However, other species have been associated with must fermentation, such as Saccharomyces uvarum (Saccharomyces bayanus var. uvarum) ... -
Influencia de diferentes fuentes de nitrógeno sobre el crecimiento y la fermentación de levaduras en mostos de uva
(Ministro de Ciencia y Tecnología, Gobierno de la Provincia de Córdoba, 2022-11-11)En Argentina, la vitivinicultura representa un importante componente en las economías productivas de las provincias de Mendoza y San Juan. La obtención de bioetanol 1G a partir de uvas de bajo valor enológico podría aportar ... -
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 ... -
Optimization of fermentation-relevant factors: A strategy to reduce ethanol in red wine by sequential culture of native yeasts
(2018-08-14)Current consumer preferences are determined by well-structured, full-bodied wines with a rich flavor and with reduced alcohol levels. One of the strategies for obtaining wines with reduced ethanol content is sequential ... -
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 ... -
Valorización de variedades criollas de uvas mediante un abordaje microbiológico
(Asociación Colombiana de Micología (ASCOLMIC), 2022-12-19)La denominación de uvas criollas se aplica a variedades de uva autóctonas de Sudamérica resultado del cruzamiento entre plantas de vid traídas por los españoles. La vinificación de estas variedades presenta alto interés ...
