A new improved strategy for the selection of cold-adapted antagonist yeasts to control postharvest pear diseases
Postharvest diseases cause considerable losses of harvested fruits during transportation and storage. Many yeast species have been reported as good antagonists against postharvest pear pathogens. In this work, we used a ...
Antifungal activity and action mechanisms of yeasts isolates from citrus against Penicillium italicum
(2018-07-02)
Penicillium italicum (Blue mold) is a major postharvest disease of citrus. An alternative to controlling the disease is through the use of yeasts. The purpose of the present study was to screen effective yeast antagonists ...
Isolation, identification and selection of antagonistic yeast against Alternaria alternata infection and tenuazonic acid production in wine grapes from Argentina
(Elsevier Science, 2018-02)
Epiphytic isolates with yeast characteristics from grapes of the Malbec cultivar were obtained in order to find antagonists against Alternaria alternata. From a total of 111 isolates, 82% corresponded to the yeast-like ...
Enhancing the efficacy of yeast biocontrol agents against postharvest pathogens through nutrient profiling and the use of other additives
(Academic Press Inc Elsevier Science, 2018-06)
Vishniacozyma victoriae and Pichia membranifaciens were selected in a previous work for their biocontrol effectiveness against Penicillium expansum and Botrytis cinerea, the causal agents of blue and grey mold of pear ...
Antagonistic interactions between garden yeasts and microfungal garden pathogens of leaf-cutting ants
(Springer, 2009-10-01)
We investigate the diversity of yeasts isolated in gardens of the leafcutter ant Atta texana. Repeated sampling of gardens from four nests over a 1-year time period showed that gardens contain a diverse assemblage of yeasts. ...

Yeast biocontrol of fungal spoilage of pears stored at low temperature
To reduce the use of fungicides, biological control with yeasts has been proposed in postharvest pears. Most studies of antagonists selection have been carried out at room temperature. However, in regions like North
Patagonia ...
Efficacy and putative mode of action of native and commercial antagonistic yeasts against postharvest pear pathogens
(Elsevier Science, 2013-06)
The putative mechanisms of action involved in the biocontrol capacity of four yeast strains (Cryptoccocus albidus NPCC 1248, Pichia membranifaciens NPCC 1250, Cryptoccocus victoriae NPCC 1263 and NPCC 1259) against Penicillium ...
Impact of antagonistic yeasts from wine grapes on growth and mycotoxin production by Alternaria alternata
(Wiley Blackwell Publishing, Inc, 2021-03)
Aims: Alternaria alternata is a major contaminant of wine grapes, meaning a health risk for wine consumers due to the accumulation of toxic metabolites. To develop a successful biofungicide, the effectiveness of epiphytic ...
