Lab M's new DRCM (ISO) is unique in being the only complete
and ISO formulated Differential Reinforced Clostridial Medium on the market.
DRCM (ISO) is used for the detection of clostridia spores - used as an
indicator of faecal contamination - from water and environmental samples using
the Most Probable Number (MPN) technique. It rapidly provides a visual
indication of the presence or absence of the target organism.
Part of the company's highly regarded anaerobe range, this
standardised medium is formulated to ISO 26461-1 for the detection and
enumeration of the spores of sulphite-reducing anaerobes (Clostridia) in water.
Simple to prepare, DRCM (ISO) enables the confident detection and enumeration
of the spores of sulphite-reducing anaerobes (clostridia) in just 46 hours.
Widespread in the environment, the spores of
sulphite-reducing anaerobes are more resistant than vegetative cells to
physical and chemical change, and to chlorination, often surviving in water for
long periods. Clostridia spores in particular can be useful indicators of
intermittent and remote faecal contamination.
After first heat treating samples to remove vegetative
cells, DRCM is used with the Most Probable Number (MPN) method to determine
clostridia content per volume of sample. Thanks to the inclusion of iron (III)
citrate in the DRCM formulation, blackening of the medium indicates sulphite
reduction, highlighting the presence of sulphite-reducing bacteria.
