In most sub-Saharan African countries, staple cereal grains harbor many fungi and some produce mycotoxins that negatively impact health trade. Maize three small grain cereals (sorghum, pearl millet, finger millet) produced by smallholder farmers in Zimbabwe during 2016 2017 were examined for fungal community structure, total aflatoxin (AF) fumonisin (FM) content. A of 800 maize 180 samples collected at harvest storage from four agroecological zones. Fusarium spp. dominated the associated...
Fungi contaminate various crops worldwide. Maize, an important human staple and livestock cereal, is susceptible to contamination with fungi in the field.
Aspergillus section Flavi (Flavi) is a diverse group of fungal species whose common members include A. flavus and parasiticus. These are well-known for the production aflatoxin (AF) B G other toxic metabolites, like cyclopiazonic acid (CPA). They saprophytic soil dwellers also become crop opportunistic epiphytes. The consequence contamination with mycotoxins, such as carcinogenic AF. We investigated community structure maize that their surrounding soil, including mycotoxigenicity....
Abstract Through partitioning of ecological niches, several fungi are able to coexist on the same host crop. In (partial) absence niche partitioning, competitive exclusion among can occur. Competitive is one bases for biocontrol. We investigated fungal correlations, in terms relative abundance fungi, pre-harvest maize, as a natural ecosystem model. Internal mycobiome maize was used establish correlations. The had been harvested from dry and wet agro-ecological zones Zambia. abundances genera...
Aflatoxins (AFs) are considered to play important functions in species of Aspergillus section Flavi including an antioxidative role, as a deterrent against fungivorous insects, and antibiosis. Atoxigenic known degrade AF-B1 (B1). To better understand the purpose AF degradation, we investigated degradation B1 AF-G1 (G1) role Flavi. toxigenic were treated with artificial G1 or without antioxidant selenium (Se), which is expected affect levels AF. After incubations, measured by HPLC. estimate...
