Two Candida strains were isolated from an industrial batch reactor for fermentation of waste sulfite liquor. Pure cultures of these yeasts assimilate single substrates contained in waste sulfite liquor with different specific activity. The respiration rate is influenced by some induction substrates, too. In a mixed substrate model corresponding to waste sulfite liquor the single substrates are metabolized by pure cultures in a specific sequential manner. These sequences change during degradation of mixed substrates by mixed cultures. The spectrum of metabolized substrates, however, is not reduced. This fact is important for energy balance or for waste water contamination.
