This lactose containing selective medium has been used for the determination of the coli-aerogenes content of water, milk and other dairy products, dairy equipment, and food products 1,2. Due to the addition of selective inhibitory components, neutral red, crystal violet, and bile salts, the medium provides selectivity against non-target Gram-positive bacteria.
Use Violet Red Bile Agar for examination of food, animal feed, and environmental samples for the presence of indicator groups such as coliforms. Besides safety, indicator groups provide a measure of food quality and spoilage potential. One of the most common groups of bacteria employed as indicator organisms by the food industry are the coliforms, which can be regarded as a subgroup within the Enterobacteriaceae.

Easy-to-read: organisms rapidly fermenting the lactose coliforms form red-purple colonies with red-purple halos; while late lactose fermenters form pale colonies with greenish halos. Selective: crystal violet and bile salts suppress the growth of non-target Gram-positive bacteria. Not all products are available for sale in all territories.

Thermo Fisher Scientific Inc.Directions Suspend Description Dichloran-Glycerol DG18 Agar Base is based on the formulation described by Hocking and Pitt 1 and is recommended for the enumeration and isolation of xerophilic moulds from dried and semi-dried foods. Examples of these are dried fruits, spices, confectionery, cereals, nuts and dried meat and fish products.
Glycerol was chosen because of advantages it showed over sodium chloride and sugars which have traditionally been used to formulate media of reduced a W 1.
The medium also contains dichloran which inhibits spreading of mucoraceous fungi and restricts the colony size of other genera. This restrictive characteristic makes the medium especially suitable for enumeration because it allows unobscured growth of organisms that ordinarily form small colonies.
A modification to the formula has been described in which the addition of Triton-X to DG18 agar increases the inhibition of vigorously-spreading fungi 2.
Listeria Selective Oxford Agar Base (Dehydrated)
In this study it was found that two of the fungi commonly isolated from dried foods in high numbers, Aspergillus penicilloides and Wallemia sebigrow very poorly or not at all on DRBC.

Directions Suspend 40g in 1 litre of distilled water and bring to the boil to dissolve completely. Description Sheep Blood Agar Base was developed to meet the demand for an especially nutritious blood agar base which would permit the maximum recovery of organisms without interfering with their haemolytic reactions when used with sheep blood.
Nutrient Agar (Dehydrated)
Blood Agar Base No. These mixed haemolytic reactions were due to trace amounts of fermentable carbohydrates in yeast extract and the physiological differences of sheep blood when compared to horse blood 1.
Having identified the causes of the mixed haemolytic reactions, the Sheep Blood Agar Base was formulated to be compatible with sheep blood. Comparisons with other blood agar bases supplemented with sheep blood have shown that with Sheep Blood Agar Base the growth of many bacteria - especially the fastidious streptococci - is considerably improved, and the expected beta haemolytic reaction is achieved with Streptococcus pyogenes. Appearance Dehydrated medium: Straw-coloured, free-flowing powder Prepared medium: Straw-coloured gel.

This non-selective medium contains beef extracts combined with peptone, yeast extracts and sodium chloride to provide the nitrogen compounds, carbon, vitamins and some trace ingredients necessary for the growth of bacteria. Nutrient Agar is a basic culture medium used to subculture organisms for maintenance purposes or to check the purity of subcultures from isolation plates prior to biochemical or serological tests.
In semi-solid form, as agar slopes or agar butts, the medium is used to maintain control organisms 1. Nutrient Agar is suitable for teaching and demonstration purposes. It contains a concentration of 1. The medium, without additions, may be used for the cultivation of organisms which are not exacting in their nutritional requirements.
