A Saccharomyces cerevisiae Wine Strain Inhibits Growth and Decreases Ochratoxin A Biosynthesis by Aspergillus carbonarius and Aspergillus ochraceus
The aim of this study was to select wine yeast strains as biocontrol agents against fungal contaminants responsible for the accumulation of ochratoxin A (OTA) in grape and wine and to dissect the mechanism of OTA detoxification by a Saccharomyces cerevisiae strain (DISAABA1182), which had previously been reported to reduce OTA in a synthetic must. All of the yeast strains tested displayed an a...
متن کاملEfficacy of different caffeine concentrations on growth and ochratoxin A production by Aspergillus species.
UNLABELLED The objective of this study was to evaluate the effect of different caffeine concentrations (0-4%) on (i) lag phase prior to growth, (ii) growth rates and (iii) ochratoxin A (OTA) production by strains from the Aspergillus section Circumdati and Aspergillus section Nigri groups, isolated from coffee, when grown on a conducive medium at 0·98 water activity and 30°C. The lag phases pri...
متن کاملEssential Oils Modulate Gene Expression and Ochratoxin A Production in Aspergillus carbonarius
Ochratoxin A (OTA) is a mycotoxin, mainly produced on grapes by Aspergillus carbonarius, that causes massive health problems for humans. This study aims to reduce the occurrence of OTA by using the ten following essential oils (E.Os): fennel, cardamom, anise, chamomile, celery, cinnamon, thyme, taramira, oregano and rosemary at 1 µL/mL and 5 µL/mL for each E.O.As a matter of fact, their effects...
متن کاملeffect of carbon, nitrogen sources and water activity on growth and ochratoxin production of aspergillus carbonarius (bainier) thom
background ochratoxin a (ota) is a toxic secondary metabolite produced by fungi belonging to aspergillus and penicillium genera. the production of ota is influenced by environmental conditions and nutritional requirements. the postharvest application of bunches of table grape fruit (tgf), with water activity of 0.8 aw, was highly effective for controlling ota contamination in vitro and in vivo ...
