Brucella agar is an enriched non-selective medium that supports the growth of fastidious and slow growing, obligately anaerobic micro-organisms due to its content of peptones, dextrose and yeast extract. The medium is supplemented with sheep blood, haemin and vitamin K which provide essential nutrients for certain anaerobes. -
A very nutritious general-purpose medium based on Columbia Agar Base enriched with 7% Horse Blood, suitable for the cultivation and maintenance of most organisms including many fastidious anaerobes of clinical significance. -
This is a modification of the traditional liquid media used to differentiate and identify micro-organisms. It consists of a Buffered Tryptose base containing Lactose and solidified with Gelatin which permits detection of Gelatin Liquefaction where appropriate. Phenol Red Indicator is also included as an indicator of pH change. -
For the enumeration of Escherichia coli and coliform organisms in water using a Membrane Filtration Technique. Previously known as Membrane Enriched Teepol Broth, Lauryl Sulphate has replaced Teepol 610, which is no longer available. Phenol Red is included in the medium making it possible for coliforms to be more readily detected following incubation. -
This is a selective differential medium for the isolation of Listeria monocytogenes from food, clinical and environmental specimens. -
Traditionally, membrane Lauryl Suphate Broth (mLSB) was used as the standard media for isolating coliforms (including E. coli) from drinking water. Primary membrane Lactose Glucuronide Agar (mLGA) is a chromogenic modification of mLSB formulation aimed at reducing costs by reducing the number of filters used per test sample and aiding in the recovery and identification of coliforms and <em,>E. coli . The medium has been modified from the mLSB formulation by the incorporation of X-glucuronide, sodium pyruvate and agar. X-glucuronide is incorporated to allow for the presumptive isolation of E. coli, sodium pyruvate aids recovery of chlorine stressed organisms and agar is incorporated to remove the need for absorbent pads. This medium is recommended for the enumeration of coliform bacteria and E. coli by a single membrane filtration technique in The Environment Agency’s - The Microbiology of Drinking Water 2009 (Part 4).
