Parallel streaks of C. krusei 5 mm apart on Sabouraud’s dextrose agar incubated at 30 °C. a – after 2 days some early mycelia. b – after 3 days heavy inside mycelial rowth. c and d - outer sides of both streaks after 3 days show no outside mycelial growth. Inside and outside refer to setup shown on Fig. 1. e – Parallel streaks of C. krusei, viable (left side) vs. heat killed (right side) after 3 days, no mycelia are formed. SB = 100 μm
