Short summary
We studied filamentous macroscopic algae growing in metal-rich stream water that leaked from a former uranium-mining district. These algae were encrusted with Fe-deposits that were associated with microbes, mainly Gallionella-related Fe-oxidizing bacteria, and extracellular polymeric substances. Algae with a lower number of chloroplasts often exhibited discontinuous series of precipitates, likely due to the intercalary growth of algae which allowed them to avoid detrimental encrustation.
