How rootstocks influence salt tolerance in grapevine?. The role of conferred vigor and ionic exclusion
(2016)The aim of this work was to evaluate whether selected grapevine rootstocks can confer greater salt tolerance than own-rooted Vitis vinifera L. A trial was carried out with potted own-rooted 'Malbec' vines and also grafted ... -
Drought will not leave your glass empty : low risk of hydraulic failure revealed by long-term drought observations in world’s top wine regions
(2018)Grapevines are crops of global economic importance that will face increasing drought stress because many varieties are described as highly sensitive to hydraulic failure as frequency and intensity of summer drought increase. ... -
Natural occurrence of Ochratoxin A in musts, wines and grape vine fruits from grapes harvested in Argentina
(2010-08)In this study, ochratoxin A (OTA) occurrence in Argentinean musts, wines and dried vine fruits was evaluated, alongside with the performance of OchraStarTM columns for OTA extraction. In all the three matrices analyzed, ... -
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 ... -
Isolation of a yeast strain able to produce a polygalacturonase with maceration activity of cassava roots
(2013-06)The objective of the present study was the isolation of a yeast strain, from citrus fruit peels, able to produce a polygalacturonase by submerged fermentation with maceration activity of raw cassava roots. Among 160 yeast ... -
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 ... -
Control of Ochratoxin A production in grapes
(2012-05)Ochratoxin A (OTA) is a mycotoxin commonly present in cereals, grapes, coffee, spices, and cocoa. Even though the main objective of the food and feed chain processors and distributors is to avoid the extended contamination ... -
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 ... -
In vitro cultures of Vitis vinifera L. cv. Chardonnay synthesize the phytoalexin nerolidol upon infection by Phaeoacremonium parasiticum
(2013)This study investigated terpene synthase (TPS) activity and terpene antifungal metabolites in calluses and cell suspension cultures of Vitis vinifera cv. Chardonnay infected with Phaecremonium parasiticum, one of the fungi ... -
Characterization of the phenolic fraction from Argentine wine and its effect on viability and polysaccharide production of Pediococcus pentosaceus
(2015-12)Objectives: To qualitatively and quantitatively characterize a low molecular weight phenolic fraction (LMF) of Malbec wine from Cafayate, Argentina, and evaluate its effect on viability and exopolysaccharide production of ... -
Biological control as a strategy to reduce the impact of mycotoxins in peanuts, grapes and cereals in Argentina
(2015)Mycotoxins including aflatoxins, deoxynivalenol, fumonisins and ochratoxin A are among the main fungal secondary metabolites detected as natural contaminants in South America in different commodities such as peanuts ... -
Incidence of Grapevine Leafroll Associated Viruses -1, -2, and -3 in Mendoza vineyards
(2010-12)Viticulture is important in Argentina's economy, especially in the province of Mendoza, which is responsible for more than 75% of the crop cultivated area. In this work, we evaluated the incidence of Grapevine leafroll-associated ... -
Partial molecular and biological characterization of grapevine leafroll-associated virus 2 isolates from Argentina
(2015-05)Grapevine leafroll is one of the most important viral disease affecting grapevines the world over. One of the viruses associated with this disease is Grapevine leafroll associated virus 2 (GLRaV-2), which has two remarkable ... -
Germplasm evaluation of the native cultivar “Torrontes Riojano” (Vitis vinífera L.) collected in the Northwest of Argentina
(2015)The cultivar ‘Torrontés Riojano’ (Vitis vinifera L.) was derived from a cross of ‘Muscat of Alexandria’ and ‘Criolla Chica’. Its origin was probably not a directed cross in Mendoza Argentina during the colonial period. ... -
Nucleotide sequence of key genes from the biosynthesis pathway of the major flavonoid in “Malbec” and “Cabernet Sauvignon”
(2015)In red wines, important sensory attributes such as color and astringency are the result of the accumulation of anthocyanins, which are located in the berry skin (and in the pulp of teinturier cultivars). Each cultivar has ... -
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 ... -
Antifungal activity of native yeasts from different microenvironments against Colletotrichum gloeosporioides on ripe olive fruits
(2017-03)Anthracnose is a fungal disease caused by Colletotrichum species, which mainly affects olive fruits during ripening. The use of yeasts from related and unrelated microenvironments in the control of plant pathogens has ... -
