Oxoid provides a complete range of culture media for the microbiological examination of brewery water supplies as recommended in Public Health and Safety Matters Report 71
In addition to testing the water used in the manufacture of beers and lagers, it is important to test the water used in cleaning processes also, in order to minimise potential routes for contamination.
Such contamination could lead to the presence of pathogenic or spoilage micro-organisms in the final product.
The Oxoid range includes media for total microbial counts and coliform counts, in addition to media for the growth and detection of thermotolerant coliform bacteria, E coli, faecal Streptococci, sulphite-reducing bacteria and Clostridium perfringens.
These products include standard, recommended media, such as minerals modified glutamate medium (CM607), membrane lauryl sulphate broth (MM615), lauryl tryptose broth (CM451), bile aesculin agar (CM888) and Clostridium perfringens selective media (CM543, SR76, SR77; CM587, SR93, SR88).
In addition, two new media have recently been added to the water testing range: water plate count agar (ISO) (CM 1012) is a new medium for the enumeration of culturable micro-organisms in water using a colony count technique, conforming to ISO 6222:1999 (E) Water Quality; and m-CP chromogenic agar (CM 992 and SR188) permits easy identification of Clostridium perfringens colonies on the culture plate by means of a simple colour reaction.
