the process of respiration used by some anaerobic organisms, in which sulfate rather than molecular oxygen is used to oxidize organic molecules to obtain energy.
It indicated that the nitrate would be utilized preferentially by denitrification bacteria (DB) than sulfate utilized by SRB in completion with [H.sub.2] in MBfR, and nitrate respiration is energetically more favorable than sulfate respiration [31].
In addition, molybdate, a specific inhibitor of sulfate respiration (Oremland and Capone 1988), prevented the degradation of the hydrocarbon (Zhang and Young 1997).
