When lactate was able to reduce both ,nitrate and sulfate, completely (Fig. 4B and E), ,sulfate removal, was slower than ,nitrate removal,. These results prove neither mechanism A or B (Fig. 1 ). Both result in the net oxidation of lactate with ,nitrate,, and it is difficult to determine from the steady-state profiles whether this is occurring through intermediate sulfur cycling.
