Electron donor‐limited chemostat enrichments were used to isolate sulphate‐reducing bacteria (SRB) from human faeces. When acetate, lactate, propionate, butyrate or amino acids were used as electron donors, SRB identical to those found using traditional isolational methods (agar shake dilution series) were obtained. However, chemostat enrichments facilitated the isolation of SRB able to metabolize mixtures of alcohols (C 1 ‐C 5 ) and mixtures of fatty acids (C 2 ‐C 6 ) which had not been detected by the direct isolation techniques.
