Effects of potassium sorbate and environmental factors on growth of tobacco spoilage fungi
Mutasa-Gottgens, Euphemia; Magan, N.; Seal, K.J. (1990-10)Potassium sorbate was found to inhibit germination and growth of a range of spoilage fungi isolated from tobacco below pH 5. However, at and above pH 5 the efficacy of potassium sorbate was influenced by substrate composition ... -
Proof of concept: could snake venoms be a potential source of bioactive compounds for control of mould growth and mycotoxin production
Verheecke-Vaessen, C.; Monte, J.; Garcia-Cela, E.; Magan, N.; Medina, A. (2020-06-29)The objective was to screen 10 snake venoms for their efficacy to control growth and mycotoxin production by important mycotoxigenic fungi including Aspergillus flavus, Aspergillus westerdijkiae, Penicillium verrucosum, ... -
Utilization of potassium sorbate by tobacco spoilage fungi
Mutasa-Gottgens, Euphemia; Magan, N. (1990-10)Aspergillus, Eurotium and Penicillium species (total of 11 isolates) were examined for their ability to utilize potassium sorbate as a sole carbon source in liquid culture, under different pH and temperature conditions. ... -
The water-content water activity relationship of cured tobacco and water relations of associated spoilage fungi
Mutasa-Gottgens, Euphemia; Seal, K.J.; Magan, N. (1990)The relationship between moisture content and water activity (aw) in cured tobacco was significantly influenced by sugar content. Overall, high sugar tobaccos such as Oriental and Virginia had a higher moisture content at ...
