Influence of propionic acid on growth and aflatoxin production by Aspergillus flavus in liquid submerged and solid
1Department of Bioscience & Biotechnology, Strathclyde University, Glasgow, Scotland.
Abstract:
The present experiments demonstrate that sublethal concentrations of propionic acid stimulated aflatoxin production considerably in submerged shaken culture and solid substrate culture of Aspergillus flavus. In liquid conditions aflatoxin formation was significantly influenced by the time of addition of propionic acid. The spores initially swelled into large spherical cells, and the resultant hyphae developed into a swollen, stunted, and excessively branched mycelium.
