Sulfate-reducing bioreactors subjected to high sulfate loading rate or acidity: variations in microbial consortia

Abstract

Key points Influents with high sulfate loading rate or low pH were successfully treated. Microbial consortia showed versatility and adaption to changing operation. Unknown interactions among microbial groups makes interpretation challenging.
