Assessment of soil properties, plant yield andcomposition, after different type and applicationsmode of organic amendment in a vineyard of Mendoza, Argentina = Evaluación de propiedades edáficas químicas, biológicas, rendimiento y composición vegetal en un viñedo de Mendoza (Argentina) con diferentes tipos y modos de aplicación de abono orgánico
(2018)Research on grapevines has indicated that organic amendment application (OAA) increasesthe nutrient content of soil and plant tissue. Microbial functional groups are extensively used assoil fertility indicators because ... -
Germination of six native perennial grasses that can be used as potential soil cover crops in drip-irrigated vineyards in semiarid environs of Argentina
(2015-02)Native desert plants have structural adaptations that maximize photosynthesis rates and minimize water loss. They can be successfully utilized as soil cover crops in drip-irrigated vineyards where water availability is ... -
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 ... -
Carotenoid profile produced by Bacillus licheniformis Rt4M10 isolated from grapevines grown in high altitude and their antioxidant activity
(2018-07)Bacillus licheniformis (BL) strains are used for industrial production of exoenzymes, antibiotics and secondary metabolites, and also serve as probiotics. Some strains sequester heavy metals, promoting plant growth or ... -
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) ... -
Effects of pH and sugar concentration in Zygosaccharomyces rouxii growth and time for spoilage in concentrated grape juice at isothermal and non-isothermal conditions
(2014-04)The effect of pH (1.7–3.2) and sugar concentration (64–68 °Brix) on the growth of Zygosaccharomyces rouxii MC9 using response surface methodology was studied. Experiments were carried out in concentrated grape juice ... -
Fruit-localized photoreceptors increase phenolic compounds in berry skins of field-grown Vitis vinifera L. cv. Malbec
