Evaluation of Saccharomyces cerevisiae strains as probiotic agent with aflatoxin B1 adsorption ability for use in poultry feedstuffs
(2012-08)In this study the aflatoxin B1 (AFB1) removal capacity, the tolerance to salivary and gastrointestinal conditions, autoaggregation and coaggregation with pathogenic bacteria of Saccharomyces cerevisiae strains isolated ... -
Evaluation of the effectiveness of potential biocontrol yeasts against black sur rot and ochratoxin A occurring under greenhouse and field grape production conditions
(2016)The efficacy of two strains of Lanchancea thermotolerans in preventing the growth and ochratoxin A (OTA) accumulation of ochratoxigenic fungi under greenhouse and field conditions were evaluated during three consecutive ... -
Exhausted grape marc and organic residues composting with polyethylene cover: process and quality evaluation as plant substrate
(Elsevier, 2019-09)In Argentina, wine production is one of the most important economic activities, producing a large quantities of organic wastes. Composting is a viable alternative to treat these residues, with the possibility to obtain ... -
Expression of grapevine AINTEGUMENTA-like genes is associated with variation in ovary and berry size
(2016-05)Fruit size is a highly important trait for most fruit and vegetable crops. This trait has been a main selection target and could be involved in divergent selection processes leading to the differentiation between modern ... -
Extraction, Evolution, and Sensory Impact of Phenolic Compounds During Red Wine Maceration
(2014)We review the extraction into wine and evolution of major phenolic classes of sensory relevance. We present a historical background to highlight that previously established aspects of phenolic extraction and retention into ... -
First american records of Aphis intybi (Hemiptera: Aphididae) with notes on two other related adventive species in Argentina
(Florida Entomological Society, 2012-12)Aphis intybi Koch is recorded for the first time in North and South America. Measurements for the identification of this species in comparison with Aphis craccivora Koch are given. Aphis cytisorum Hartig is recorded for ... -
First report of Dactylonectria alcacerensis, Dactylonectria macrodidyma and Ilyonectria liriodendri associated with black-foot disease of grapevine in Argentina
(American Phytopathological Society, 2022-03-07)Black-foot is a fungal disease that affects young vines and planting material in the countries where grapevines are cultivated. During the 2018 grape-growing season, symptoms of reduced vigor, short internodes, leaf ... -
First report of grapevine red blotch virus infecting grapevine in Argentina
(Springer, 2019-04)Argentina is the fifth wine producer worldwide and 10th global grapevine producer, with over 2,100,000 tons of grapes harvested in 2017. So far, 12 viruses have been identified in grapevine in Argentina (Debat et al. 2019). -
Free Volatile Compounds of cv. Pedro Giménez (Vitis vinifera L.) White Grape Must Grown in San Juan, Argentina
(2018)The free aromatic composition of must from Pedro Giménez grapes, grown in San Juan, Argentina, was characterised. Samples from the vintages of 2008 and 2009 were analysed by gas chromatography–mass spectrometry–solid phase ... -
Fruit-localized photoreceptors increase phenolic compounds in berry skins of field-grown Vitis vinifera L. cv. Malbec
(2015-02)Sunlight exposure has multiple effect on fruits, as it affects the light climate perceived by fruit photoreceptors and fruit tissue temperature. In grapes (Vitis vinifera L.), light exposure can have a strong effect on ... -
Generation of a non-transgenic genetically improved yeast strain for wine production from nitrogen-deficient musts
(MDPI, 2020)The yeast Saccharomyces cerevisiae is the main species responsible for the process that involves the transformation of grape must into wine, with the initial nitrogen in the grape must being vital for it. One of the main ... -
Generation of intra- and interspecific Saccharomyces hybrids with improved oenological and aromatic properties
(Wiley, 2022-04)Non-wine yeasts could enhance the aroma and organoleptic profile of wines. However, compared to wine strains, they have specific intolerances to winemaking conditions. To solve this problem, we generated intra- and ... -
Genetic and Transcription Profile Analysis of Tissue-Specific Anthocyanin Pigmentation in Carrot Root Phloem
(MDPI, 2021-09)In purple carrots, anthocyanin pigmentation can be expressed in the entire root, or it can display tissue specific-patterns. Within the phloem, purple pigmentation can be found in the outer phloem (OP) (also called the ... -
Genetic characterization of grapevine-infecting Botrytis cinerea isolates from Argentina = Caracterización genética de aislamientos de Botrytis cinerea obtenidos en vides de Argentina
(2010-06)Background: Botrytis cinerea is an ascomycete with a high genetic diversity and complex population structure, as reported from several hosts and sites. However, nothing is known about its genetic diversity in Argentina. Aims: ... -
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) ... -
Genomic and phenotypic comparison between similar wine yeast strains of Saccharomyces cerevisiae from different geographic origins
