This medium is recommended by BSI and ISO for the enumeration of viable organisms in milk and other dairy products. It can also be used as a general-purpose medium for the cultivation of most organisms, particularly those that are less fastidious in their nutritional requirements. -
Modified Semi Solid Rappaport Vassiliadis Medium (MSRV) is a modification of Rappaport-Vassiliadis enrichment broth for detecting motile Salmonella spp. in faeces and food products. The original research on MSRV Medium revealed a semi-solid could be used as a rapid and sensitive test for isolating motile Salmonella spp. from food products following pre-enrichment or selective enrichment. The semi-solid medium allows motility to be detected as halos of growth around the original point of inoculation.
-
This is a solution of novobiocin used as the selective agent in Modified Semi Solid Rappaport Vassiliadis Medium (BM4031) for the detection of motile Salmonella spp.
-
This is a non-nutrient medium based on Page’s Amoeba Saline, a buffered salt solution, solidified with 1.5% Agar.
-
This is a selective enrichment broth for the isolation of Salmonella spp. from pharmaceutical, food, dairy and environmental samples. Malachite Green and Magnesium Chloride are included in the formulation as selective agents due to their ability to inhibit most enteric organisms whilst allowing Salmonella spp. to multiply freely. Gram +ve bacteria and most other enteric bacteria, are typically susceptible to or inhibited by Malachite Green, the high osmotic pressure and/or the low pH of the medium. It should be noted that S.typhi and S.choleraesuis are sensitive to Malachite Green and may therefore be inhibited. This medium conforms to the requirements of the Harmonised USP/EP/JP. -
An osmotically controlled solution for the preparation of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The solution may also be used in the sampling of food production apparatus by the rinse and swab method. -
This is a selective medium for the isolation of yeasts and fungi and is particularly suitable for use in sterility testing. The low pH (5.6) of the medium is inhibitory to most bacteria and many diagnostic features such as spores and pigmentation are well developed on this medium. The formulation of this medium conforms to the requirements of the Harmonized USP/EP/JP. -
Sterile Isotonic Saline suitable for use in preparation of food samples and/or as a rinse during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory. -
This medium is utilised for the transportation and cryopreservation of Streptococcus pneumoniae & Neisseria meningitidis isolates.
-
This is a medium that can be used to differentiate between some of the Enterobacteriacae on the basis of four reactions, fermentation of Lactose, Glucose and Sucrose and the production of H2S. For use the medium is inoculated using a pure culture of the test organism which should be smeared onto the surface of the slope and stabbed into the butt of the medium. For details of the many reactions that may arise during the use of this medium reference should be made to one of the many standard textbooks.
-
This is a plate count agar originally suggested by the American Public Health Association for the estimation of total viable counts in food and dairy products.
-
This is a general-purpose complex medium for the cultivation and isolation of aerobic and anaerobic microorganisms. The base medium, Tryptone Soya Agar (Soybean-Casein Digest agar), conforms to the Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EP), and Japanese Pharmacopoeia (JP). The medium can be incubated under aerobic or anaerobic conditions after use for sterility testing, air sampling and other areas of bacteriological investigation. -
This is a general-purpose complex medium for cultivation and isolation of fastidious bacteria, yeasts and moulds. The formulation is based on the United States Pharmacopoeia (USP Medium II) and European Pharmacopoeia (EP Medium B). Lecithin and Polysorbate 80 (Tween 80) are added to inactivate surface disinfectants. The medium can be incubated under aerobic or anaerobic conditions for sterility testing, air sampling and other areas of bacteriological investigation. -
Tryptone Soya Broth is also commonly referred to as Soybean-Casein Digest Medium or Tryptic Soya Broth and is abbreviated as TSB. This is a general purpose and nutritious medium for the non-selective enrichment of non-fastidious and some fastidious organisms. Tryptone and Soy peptone are the nitrogen sources in the medium. Glucose is the carbon energy source that facilitates organism growth. Sodium chloride maintains osmotic balance; Di-potassium phosphate is a buffering agent to prevent auto-sterilisation due to acid production during the growth of some organisms. Tryptone Soya Broth formulation conforms to the Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EU), and Japanese Pharmacopoeia (JP). -
This is a general-purpose broth for cultivation of fastidious bacteria, yeasts and moulds. The medium incorporates Polysorbate 80 to act as an emulsifying agent and inactivate phenols. Lecithin is also incorporated to inactivate quaternary ammonium compounds. The medium can be incubated under aerobic or anaerobic conditions for sterility testing, and other areas of bacteriological investigation. -
Tryptone Water is an alternative medium to Peptone Water and more reliable for the testing of Indole production. The medium has a high content of Tryptophan that many organisms, particularly coliforms, break down to form Indole. After incubation add a few drops of Indole reagent to determine the Indole reaction (Red colour is Positive).
