Increasing knowledge of the deleterious health and economic impacts of aflatoxin in crop commodities has stimulated global interest in aflatoxin mitigation. Current evidence of the incidence of Aspergillus flavus isolates belonging to vegetative compatibility groups (VCGs) lacking the ability to produce aflatoxins (i.e., atoxigenic) in Ghana may lead to develop an aflatoxin biocontrol strategy to...

Abstract This research was done on the assumption that the risk for hepatocellular carcinoma (HCC) development that attributed to the consumption of highly contaminated food (HCF) with aflatoxin, may have a major contribution to the total of expected risk. If this hypothesis is true, it is easy to apply an effective and low‐cost intervention approach by excluding HCF and then subjecting it to...

Contamination by fungi may pose a threat to the long-term operation of the International Space Station because fungi produce organic acids that corrode equipment and mycotoxins that harm human health. Microgravity is an unavoidable and special condition in the space station. However, the influence of microgravity on fungal metabolism has not been well studied. Clinostat rotation is widely used to...
