'Candida albicans' as an Alternative Sanitary-Indicator Organism for Waters Containing Acid Mine Drainage

摘要

Microbiological studies were conducted to assess the potential of using Candida albicans as a sanitary-indicator organism in streams impacted by acid mine drainage (AMD) and organic wastes. C. albicans was detected at low densities in AMD, particularly when compared to the occurrence of traditional indicator bacteria. The relatively lower density of C. albicans in AMD was a reflection of its likewise low incidence in raw sewage. Pure-culture survival studies indicated that C. albicans is extremely resistant to the adverse effects of AMD as demonstrated by prolonged persistence of at least three days. In addition to its extended survival, C. albicans incurred minimal sublethal injury from AMD stress.
