Impact on Sensory and Aromatic Profile of Low Ethanol Malbec Wines Fermented by Sequential Culture of Hanseniaspora uvarum and Saccharomyces cerevisiae Native Yeasts
(MDPI, 2019-07)It is well known that high ethanol levels in wines adversely affect the perception of new wine consumers. Moreover, numerous issues, such as civil restrictions, health risk and trade barriers, are associated with high ... -
Incidence of osmophilic yeasts and Zygosaccharomyces rouxii during the production of concentrate grape juices
(2017)Zygosaccharomyces rouxii is the main spoilage yeast of grape juice concentrates. Detection and identification of Z. rouxii during the production of grape juice concentrate is critical to prevent spoilage in the final ... -
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 ... -
Inoculation strategies to improve persistence and implantation of commercial S. cerevisiae strains in red wines produced with prefermentative cold soak
(Elsevier, 2018)Prefermentative cold soak is a winemaking technique aimed at enhancing aroma and colour extraction in red wines. This study aimed at evaluating implantation and persistence rates of commercial active dry yeast strains (ADY) ... -
Insights into the lemon (Citrus limon) epiphytic microbiome: impact of the biocontrol yeast Clavispora lusitaniae 146
(BMC, 2025-01)Background: Postharvest lemons are affected by several fungal infections, and as alternatives to chemical fungicides for combating these infections, different microbial biocontrol agents have been studied, with the Clavispora ... -
Levaduras aisladas de mieles como antagonistas de mohos patógenos de cultivos
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2020-12)Se buscó el aislamiento de levaduras de muestras de miel de la Provincia de Jujuy, Argentina, con el objetivo de utilizarlas in vitro como antagonistas de mohos patógenos pre- y poscosecha, de diferentes cultivos de interés, ... -
Levaduras autóctonas con potencial biotecnológico para la valorización del orujo de uva en procesos sostenibles de producción de bioetanol
(Asociación Argentina de Microbiología (AAM), 2025-09) -
Levaduras autóctonas y su potencial biotecnológico
(EEA Alto Valle, INTA, 2020)La fermentación se usa para conservar y mejorar las características organolépticas de los alimentos por más de 6.000 años, siendo uno de los procesos con mayor impacto en los hábitos nutricionales y la cultura alimentaria ... -
Más allá del pan y la cerveza, el papel de las levaduras en la agricultura y la silvicultura
(Estación Experimental Agropecuaria Bariloche, INTA, 2024-12)Las levaduras han sido utilizadas durante siglos en la producción de alimentos y bebidas fermentadas. En las últimas décadas, se ha descubierto que también tienen la capacidad de promover el crecimiento vegetal y proteger ... -
Molecular and enological characterization of a natural Saccharomyces uvarum and Saccharomyces cerevisiae hybrid
(2015-07)Saccharomyces cerevisiae plays a main role in the winemaking process, although other species, like Saccharomyces uvarum or Saccharomyces paradoxus, have been associated with must fermentations. It has been reported in ... -
Monitoring of killer yeast populations in mixed cultures: influence of incubation temperature of microvinifications samples
(2012-11)Killer yeasts are frequently used to combat and prevent contamination by wild-type yeasts during wine production and they can even dominate the wine fermentation. Stuck and sluggish fermentations can be caused by an ... -
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 ... -
Mutagenesis, screening and isolation of Brettanomyces bruxellensis mutants with reduced 4-ethylphenol production
