Abstract To clarify the dynamic behavior of the anaerobic acid reactor in response to pH changes, a continuous cultivation was performed. By stepwise shifting the culture pH in the acid reactor from 6.0 to 8.0, the main products were changed from butyric acid to acetic and propionic acids. This phenomenon was reproducible, reversible and was not affected by the dilution rate. It was considered that the dominant microbial populations changed in the acid reactor due to the pH shift.
