Abstract: | Anaerobic chemostat enrichments have been successfully employed to isolate acetate-utilizing, sulphate-reducing bacteria from sediments in the Tay estuary. Several different morphologically and nutritionally versatile types of sulphate-reducing bacteria have been isolated by this means which has proved especially useful when they are present in low numbers. The principal advantage of this method is that strict anaerobes such as sulphate-reducing bacteria can be isolated in a controlled and reproducible enrichment system at low growth rates. |
