摘要

We have sought to enrich for acidophiles with the capability to grow with aromatic compounds as sole carbon and energy compounds. Enrichment of aerobic acidophiles was successful with the model aromatic compounds benzoic acid, benzyl alcohol and phenol. As would be expected, at high concentrations of benzoic acid the growth of most acidophiles was inhibited. Olne group of acidophiles, however, exhibited an ability to grow with high concentrations of various aromatic acids. This success with aerobic acidophiles led us to seek anaerobic acidophiles with the capacity to degrade aromatic compounds. The enrichment of acidophiles that were able to couple aromatic degradation to sulfate reduction was also successful. With the discovery of these acidophiles, it is now possible to develop a biological treatment system for acidic waste waters containing both organic and inorganic pollutants.
