Influence of temperature on growth rate and lag phase of fungi isolated from Argentine corn

The influence of temperature on the growth of nine strains of fungi belonging to the genera Eurotium, Aspergillus, Penicillium and Fusarium has been investigated for the temperature range 15-35° C. The lag phase and the growth rate were evaluated by using a laboratory medium. The maximum growth rate...

Sumario:The influence of temperature on the growth of nine strains of fungi belonging to the genera Eurotium, Aspergillus, Penicillium and Fusarium has been investigated for the temperature range 15-35° C. The lag phase and the growth rate were evaluated by using a laboratory medium. The maximum growth rate for E. repens, A. wentii and P. chrysogenum was observed at about 25° C, for P. citrinum near 30° C and for F. semitectum and F. moniliforme between 20 and 25° C. The growth rate of A. niger, A flavus and A. parasiticus increased with increasing temperatures in the range studied. For all strains studied it appeared that the higher the growth rate the lower the lag phase was. © 1988.
