Thiocyanate and Organic Carbon Inputs Drive Convergent Selection for Specific Autotrophic Afipia and Thiobacillus Strains Within Complex Microbiomes.

ABSTRACT: Thiocyanate (SCN^-) contamination threatens aquatic ecosystems and pollutes vital freshwater supplies. SCN^--degrading microbial consortia are commercially adapted for remediation, but the impact of organic amendments on selection within SCN^--degrading microbial communities has not been investigated. Here, we tested whether specific strains capable of degrading SCN^- could be reproducibly selected for based on SCN^- loading and the presence or absence of added organic carbon. Complex microbial communities derived from those used to treat SCN^--contaminated water were exposed to systematically increased input SCN concentrations in molasses-amended and -unamended reactors and in reactors switched to unamended conditions after estab
