Abstract:

The influence of the inoculum size on growth of nine strains of fungi belonging to the genera Aspergillus, Penicillium and Fusarium was investigated. The lag phase and the growth rate were evaluated by using a synthetic medium. The growth rate was not significantly affected by the initial number of spores varying from 10 to 105. The lag phase increase with decreasing number of spores, and linear correlation between the log of the inoculum size and lag phase was observed for Aspergillus niger, A. flavus, A. wentii, A. parasiticus, Penicillium citrinum, Fusarium moniliforme and F. semitectum. A different behavior was found for A. repens and P. chrysogenum. © 1987.
