An electrolytic bioreactor, assembly and method for growing organisms capable of oxidizing metal sulfides. The reactor comprises a vessel defining an anode chamber for housing an anode, and a cultivation chamber, for housing a cathode and a culture solution, a selective barrier between such chambers, which is impermeable to the organisms and to cations, and a receptacle defining a pH control chamber for receiving samples of culture solution from the cultivation chamber so that such samples are insulated from electric current within the cultivation chamber. Preferably, the capacity of the anode chamber is about 1% to about 3% of the cultivation chamber. In accordance with the method of the present invention during operation of the reactor assembly, the pH of the culture solution is controlled by circulating samples through the pH control chamber.
