A proteomic investigation of Aspergillus carbonarius exposed to yeast volatilome or to its major component 2-phenylethanol reveals major shifts in fungal metabolism
( Elsevier B.V. , 2019 , Article)The use of yeast-derived volatile organic compounds (VOCs) represents a promising strategy for the biological control of various plant pathogens, including mycotoxin-producing fungi. Previous studies demonstrated the ... -
Ameliorative role of dietary activated carbon against ochratoxin-A induced oxidative damage, suppressed performance and toxicological effects
( Taylor and Francis Ltd. , 2022 , Article)The present study reports that dietary addition of 2.5, 5.0, 10.0 g/kg activated charcoal (AC) in broiler feed contaminated with 0.15, 0.3 and 1.0 mg/kg ochratoxin A (OTA) showed a partial reduction in intensity of mycotoxins ... -
Detection of toxigenic mycobiota and mycotoxins in cereal feed market
( Elsevier Ltd , 2018 , Article)The present study was designed to investigate the occurrence of mycotoxins and toxigenic mycobiota in cereals used as animal feed in a Qatari market. Aflatoxins (AFs) and ochratoxin A (OTA) were detected in 94 and 44% of ... -
Dietary L-carnitine and vitamin-E; a strategy to combat ochratoxin-A induced immunosuppression
( Elsevier Ltd , 2018 , Article)This study aimed to evaluate the effect of dietary ochratoxin A (OA), in the presence and absence of L-carnitine (LC) and vitamin E (VE), on the humoral immune responses of White Leghorn cockerels (WLC). One-day old white ... -
Dietary Trichosporon mycotoxinivoron modulates ochratoxin-A induced altered performance, hepatic and renal antioxidant capacity and tissue injury in broiler chickens
( Elsevier Ireland Ltd , 2021 , Article)Ochratoxin A (OTA), an important fungal metabolite in foods and feeds has been shown to induce oxidative stress and cellular injuries to human and animal subjects. This study was designed to investigate the mode of action ... -
Impact of dietary Trichosporon mycotoxinivorans on ochratoxin A induced immunotoxicity; In vivo study
( Elsevier Ltd , 2019 , Article)Ochratoxin A (OA), the secondary metabolite of certain Aspergillus and Penicillium species, is one of the potent biological immune-suppressor. The present study was designed to explore the in-vivo efficacy of Trichosporon ... -
In-vitro application of a qatari burkholderia cepacia strain (QBC03) in the biocontrol of mycotoxigenic fungi and in the reduction of ochratoxin a biosynthesis by aspergillus carbonarius
( MDPI AG , 2019 , Article)Mycotoxins are secondary metabolites produced by certain filamentous fungi, causing human and animal health issues upon the ingestion of contaminated food and feed. Among the safest approaches to the control of mycotoxigenic ... -
Investigation and Application of Bacillus licheniformis Volatile Compounds for the Biological Control of Toxigenic Aspergillus and Penicillium spp
( American Chemical Society , 2019 , Article)The present study was designed to investigate the antagonistic activity of Bacillus licheniformis BL350-2 against mycotoxigenic strains of Aspergillus and Penicillium. In vitro coincubation for 5 days indicated Aspergillus ... -
Molecular identification and biocontrol of ochratoxigenic fungi and ochratoxin A in animal feed marketed in the state of Qatar
( Elsevier Ltd , 2023 , Article)Ochratoxin A (OTA) is a toxic fungal metabolite produced by some Aspergillus and Penicillium species. This work was designed to explore the presence of OTA and ochratoxigenic fungi in feed grains marketed in Qatar and their ...
