Six chemostats containing mixed anaerobic cultures were used to investigate interactions between sulfate reduction and methanogenesis for three substrates: acetic acid, methanol, and formic acid. Sulfate reducers outcompeted methanogens for acetic acid while methanol was not utilized by sulfate reducers. For the chemostat with formic acid feed, competition was observed between methanogens and sulfate reducers with 62% and 24% of the substrate utilized by sulfate reduction and methanogenesis, respectively. A comprehensive dynamic model was developed that simulates methanogenesis and sulfate reduction in a chemostat. The model incorporates the complex chemistry of anaerobic systems and was able to predict both the steady state and the batch tests reasonably well. (Copyright (c) 1993 Water Environment Federation.)
