Increasing the pH of sewage also has an effect on the rate of sulfide generation in the slime layer by SRB. The optimum environmental pH for SRB is around pH 7.0 and the rate of sulfate reduction follows an inverted U-shaped curve with the maximum rate centered on pH 7.0 (Pomeroy and Bowlus, 1946). Raising the pH beyond 7.0 has the effect of significantly
