A proteomic investigation of Aspergillus carbonarius exposed to yeast volatilome or to its major component 2-phenylethanol reveals major shifts in fungal metabolism
Tilocca B.; Balmas V.; Hassan Z.U.; Jaoua S.; Migheli Q. ( 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 ... -

Ul Hassan, Zahoor; Al Thani, Roda; A. Atia, Fathy; Al Meer, Saeed; Migheli, Quirico; Jaoua, Samir... more authors ... less authors ( Taylor and Francis Ltd. , 2018 , Article)The present study was conducted to explore the occurrence of mycotoxins in commercial baby foods in Doha-Qatar. LCMS/MS- and HPLC-based analysis of baby food (n?=?67) for 12 mycotoxins confirmed the presence of aflatoxin ... -
Detection of toxigenic mycobiota and mycotoxins in cereal feed market
Hassan Z.U.; Al-Thani R.F.; Migheli Q.; Jaoua S. ( 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.
