Pigmentation of Candida albicans by Molybdenum

Abstract
Saccharomyces cerevisiae. Candida albicans, and some other species of Candida became pigmented when cultured on a medium that contains an appropriate compound of molybdenum. C. albicans could be identified either in pure or in mixed cultures by the distinctive pigmentation which developed in 48 to 72 hr. of inoculation. The possible value of this medium for clinical use is emphasized. It is suggested that the pigmentation of the yeasts results from the presence within the cells of colored substances that develop from the reduction of accumulated molybdate.
