Temperature influence on Penicillium citrinum Thom growth and citrinin accumulation kinetics

To study the temperature influence on both Penicillium citrinum growth and citrinin accumulation, a strain isolated from corn was cultured on Czapek agar with maize extract at 15, 20, 25 and 30 °C. Radial growth rate and lag phase were determined from the increase in colony diameter with time. The o...
