The effect of antifungal substances may depend on the number of conidia. During germination, some active molecules can be adsorbed at the surface of the cell wall of fast germinating spores, thus reducing their concentration, thereby allowing the slow germinating conidia to produce mycelium. The choice of the organisms was sometimes questionable, for example when the effects of active substances were evaluated on fungal contaminants, but also on fungal starters. Similarly, many yeasts responsible for food spoilage were studied, along with the human pathogen C. albicans
