| Abstract Aspergillus westerdijkiae is one of the most important spoilage and toxigenic fungi contaminating coffee beans and may produce ochratoxin A (OTA), a mycotoxin that characterize a health risk to the coffee consumers. Biological control strategies can be used for prevention of fungal invasion and decrease mycotoxin exposure. The aims of this study were to evaluate the in vitro effect of three Bacillus sp. biocontrol candidates on A. westerdijkiae mycelial growth, spore counts and OTA production. A green-coffee based medium was inoculated with A. westerdijkiae and Bacillus spp. (B. safensis RF69, B. amyloliquefaciens RP103 and B. subtilis RP242) and after incubation, the fungal growth, sporulation and mycotoxin production was evaluated. Mycelial... |

| Abstract Fusarium head blight is an important disease occurring in wheat, caused mainly by the fungus Fusarium graminearum. In addition to direct damage to crops, reduced quality and yield losses, the infected grains can accumulate mycotoxins (toxic metabolites originating from prior fungal growth), especially deoxynivalenol (DON). Wheat crops harvested in 2014/2015 in southern Brazil were affected by high levels of Fusarium head blight. In this context, the aim of this study was evaluate the mycotoxicological quality of Brazilian wheat grains and wheat products (wheat flour and wheat bran for DON. DON contamination was evaluated in 1,504 wheat and wheat product samples produced in Brazil during 2014. It was determined by high performance liquid... |
