Influence of the cultivation medium and pH on the pigmentation of Trichophyton rubrum

Fig 3

Change of the pH induced by T. rubrum observed over an period of 4 weeks.

Before inoculation of the fungus, the pH was adjusted to 3.5, 6 or 8 and the pH was measured every second day. Each combination of fungal strain and pH has been performed in triplicate. A: T. rubrum strain STRB012 in Tr1 liquid medium. B: T. rubrum strain STRB008 in Tr1 liquid medium. C: T. rubrum strain STRB012 in SC medium.
