The Role of Methanogenic and Sulphate Reducing Bacteria in the Degradation of Tetrachloromethane

In an upflow packed-bed reactor (0.66 1; 40 cm3/cm2.d-1) filled with polyurethane foam particles (5×5×6 mm) and inoculated with digested sludge, acetate (1 mM) was completely utilized under anaerobic conditions. Acetate was used both by sulphate reducing bacteria and methanogens.
