Figure 3. The reduction intensities of F. velutipes supplied with 0–5 mM selenite (indicated by the red colorations of the colonies).

The isolates from the stock colonies were inoculated into the media containing 0–5 mM selenite and were subjected to solid cultivation (A) static cultivation (B) and shaking cultivation (C). In another experiment (D) after shaking cultivation in selenite-free media for 14 days, the resulting mycelial pellets were treated with 0–3 mM selenite. The first pink circle indicates the beginning of the red coloration. The small circle inside represents the central part of the colony (A and B) or the large mycelial pellet (C and D) and the ring outside represents the margin of the colony (A and B) or the small mycelial pellet (C and D). The plus/minus signs on the right side of circles in (C) and (D) represent the intensities of garlic smell after selenite treatment (−: none; +: low; ++: moderate; +++: strong).
