Spores were inoculated onto a poly-l-lysine-coated glass plate making up the base of a culture vessel. Potato dextrose broth (PDB) was added and the vessel incubated for 24 h at 28 °C. The growth rate of an arbitrarily selected test hypha was measured automatically. Exposure to AMPH (0.075 μg ml-1) stopped the growth of the hypha. After washing with PDB, the same concentration of AMPH was applied again. The growth of the test hypha was not inhibited. This phenomenon was defined as adaptation to the short-term stress of AMPH. Similarly, adaptation was observed with MCZ (0.01 μg ml-1) and KCZ (0.5 μg ml-1). The time required for the test hypha to restart growth after washing with PDB depended upon the concentration of MCZ or KCZ, but not upon the concentration of AMPH., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/13500872-140-9-2409
