Treatment of anaerobic granules with heat and two chemical treatments, contacting with 2-bromoethanesulfonate (BES) and with BES + Chloroform, were applied to suppress hydrogen-consuming microorganisms. Three mesophilic expanded granular sludge bed (EGSB) reactors-R(Heat), R(BES), and R(BES + Chlo)--were inoculated with

The effects of two typical methanogenic inhibitors [2-bromoethanesulfonate (BES) and chloroform (CHCl(3))] on the bacterial populations were investigated using molecular ecological techniques. Terminal restriction fragment length polymorphism analyses (T-RFLP) in combination with clone library showed that both the toxicants not
