stressface:

The human fungal pathogen Candida albicans alkalinizes the local extracellular environment.  Two colonies of C. albicans grown for 19 days on GM-bromocresol green agar, pH 4. The fungus actively raises the pH of its surrounding environment. This alkalinization converts the normally dull green medium to a strong teal blue, whilst the filamentous fringes of the colonies (white) extend away from each other.
