Influence of water activity on Penicillium citrinum growth and kinetics of citrinin accumulation in wheat

The influence of water activity (a(w)) on both Penicillium citrinum growth and citrinin accumulation in wheat was studied. Wheat conditioned at different levels of a(w) and inoculated with a citrinin producer strain was incubated at 30°C for 2 months. Fungal growth was assessed by microscopic examin...
