The spores of sulfite-reducing anaerobes (clostridia) are wide-spread in the environment. They are present in human and animal faecal matter, in waste water and in soil. Unlike Escherichia coli and other coliform organisms, the spores sur- vive in water for long periods as they are more resistant than vegetative forms to the action of chemical and physical factors. They may thus give an indication of remote or intermittent pollution. They may even be resistant to chlorination at levels which are normally used for the treatment of water, and they are thus useful for control purposes. ISO 6461 consists of the following parts:
Part 1: Method by enrichment in a liquid medium.
Part 2: Method by membrane filtration.
This part of ISO 6461 specifies a method for the detection and enumeration of the spores of sulfite-reducing anaerobes (clostridia) by membrane filtration.
