Biocontrol of Alternaria alternata in cold-stored table grapes using psychrotrophic yeasts and bioactive compounds of natural sources
Torres Palazzolo, Carolina Andrea; Ferreyra, Susana Gisela; Iribas, Francisco Javier; Chimeno, Selva Valeria; Rojo, Cecilia; Casalongue, Claudia; Fontana, Ariel Ramón; Combina, Mariana; Ponsone, María Lorena (Elsevier, 2024-04)Alternaria alternata is a common fungal pathogen causing postharvest decay in table grapes. This study addressed the potential of autochthonous yeasts and bioactive compounds of natural sources to act as biocontrol agents ... -
Biocontrol of postharvest Alternaria decay in table grapes from Argentina
Stocco, Antonella Fabia; Diaz, Mariano Emanuel; Rodriguez Romera, Mariela Carmen; Mercado, Laura Analia; Rivero, Maria Laura; Ponsone, María Lorena (Elsevier, 2019-03-29)Postharvest diseases cause considerable losses of fruit during transportation and storage. Synthetic fungicides are primarily used to control them; however, the recent trend is to shif toward safer and more eco-friendly ... -
Biodiversity of Aspergillus section Nigri populations in Argentinian vineyards and ochratoxin A contamination
Chiotta, María Laura; Ponsone, María Lorena; Sosa, Débora María; Combina, Mariana; Chulze, Sofia Noemí (2013-12)Aspergillus section Nigri are described as the main source of ochratoxin A (OTA) contamination in grapes and wine worldwide. The knowledge of the factors affecting grape contamination by species included in this section ... -
Biological control as a strategy to reduce the impact of mycotoxins in peanuts, grapes and cereals in Argentina
Chulze, Sofia Noemí; Palazzini, Juan Manuel; Torres, Adriana; Barros, G.; Ponsone, María Lorena; Geisen, R.; Schmidt-Heydr, M.; Kohl, Jürgen (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 ... -
Control of Ochratoxin A production in grapes
Ponsone, María Lorena; Chiotta, María Laura; Palazzini, Juan Manuel; Combina, Mariana; Chulze, Sofia Noemí (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 ... -
Etiología, manejo y monitoreo de Alternaria spp. en uva de mesa
Stocco, Antonella Fabia (Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2016)En estudios previos realizados en la Estación Experimental INTA Mendoza durante la postcosecha en uvas de mesa cv. Red Globe se observó un tipo de podredumbre negra que no había sido previamente citada para la Argentina; ... -
Evaluation of behaviour of Lachancea thermotolerans biocontrol agents on grape fermentations
Nally, Maria Cristina; Ponsone, María Lorena; Pesce, Virginia Mercedes; Toro, Maria Eugenia; Chulze, Sofia Noemí (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 ... -
Evaluation of the effectiveness of potential biocontrol yeasts against black sur rot and ochratoxin A occurring under greenhouse and field grape production conditions
Ponsone, María Lorena; Nally, Maria Cristina; Chiotta, María Laura; Combina, Mariana; Kohl, Jürgen; Chulze, Sofia Noemí (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 ... -
Incidence of osmophilic yeasts and Zygosaccharomyces rouxii during the production of concentrate grape juices
