Zearalenone production and growth in drinking water inoculated with Fusarium graminearum

Abstract

Production of the mycotoxin zearalenone (ZEN) was examined in drinking water inoculated with Fusarium graminearum. The strain employed was isolated from a US water distribution system. ZEN was purified with an immunoaffinity column and quantified by high-performance liquid chromatography (HPLC) with fluorescence detection. The extracellular yield of ZEN was 15.0 ng l −1 . Visual growth was observed. Ergosterol was also indicative of growth and an average of 6.2 μg l −1 was obtained. Other compounds were also detected although remain unidentified. There is no equivalent information available. More work is required on metabolite expression in water as mycotoxins have consequences for human and animal health. The levels detected in this study were low. Water needs to be accepted as a potential source as it attracts high quality demands in terms of purity.

“…Criado et al (32) reported that fungi from the genera Alternaria, Penicillium and Cladosporium may grow in bottled mineral water, which constitutes a serious health hazard for consumers. In another study Russell and Paterson (33) confi rmed the potential of Although the results of this preliminary study show that the level of ZEA in water was not high, such an exposure might be hazardous due to potential accumulation of mycotoxins, especially if the contaminated water is used in food production for humans and animals (14,33).…”

“…According to Hartmann et al (27), the occurrence of mycotoxins in the aquatic environment is a consequence of surface run-off from cropped fi elds. Furthermore, mycotoxin producers may also develop in water (32)(33)(34). Criado et al (32) reported that fungi from the genera Alternaria, Penicillium and Cladosporium may grow in bottled mineral water, which constitutes a serious health hazard for consumers.…”

The role of wastewater treatment in reducing pollution of surface waters with zearalenone / Uloga pročišćavanja otpadnih voda u smanjenju onečišćenja površinskih voda zearalenonom

“…Information about mycotoxins in wastewater and their removal efficiency is still scarce. Lagana et al (9,10) reported that ZEA concentrations in untreated and treated wastewater reached 18.0 and 10.0 ng L Even though the reported ZEA concentrations in water are not high, their accumulation in water used for food production may present a health risk for humans and animals (5,7,8). This risk increases with the presence of other endocrine disruptors such as natural oestrogenic steroids in water (6).…”
