Bacteriological peptone is an economical source of nutrients provided by a balanced mixture of meat peptones and tryptone.The growth requirements of most non fastidious organisms will be fulfilled by the range of amino acids, peptides and proteoses in this mixture.

Glucose agar allows the demonstration of glucose fermentation (with or without gas production) as an identification test for Enterobacteriaceae or Pseudomonas spp..

Drigalski Lactose agar is used for the selective isolation of Enterobacteriaceae. It allows the differentiation of bacteria according to their ability to ferment lactose in food, pharmaceutical, cosmetic and veterinary samples.

Modified Laurylsulfate-Tryptose Vancomycin broth (mLST/V) is a selective enrichment medium used for the detection of Cronobacter sakazakii in milk and milk products.

Cronobacter Screening broth is a selective enrichment media used for the detection of Cronobacter spp. in food products and ingredients intended for human consumption and the feeding of animals. It is also used for the control of production environmental samples.
The typical composition responds to that defined in the standard ISO 22964.

CCI Agar is used for the detection of microorganisms in food products and ingredients intended for human consumption and the feeding of animals.

Violet Red Bile Agar (VRBL) is a selective medium used for the detection and enumeration of coliform and thermotolerant coliforms food products.

Thioglycolate Medium with Resazurin is used for sterility tests of biological products

Preparation

# Suspend 30.0 g of the powder in 1 liter of distilled or deionized water.

# Mix well. Heat to boil and shake until completely dissolved. Dispense into tubes.

# Sterilize in autoclave at 121°C for 15 minutes.

Quality control (35 ± 2°C / 18-24 h)

Storage

Store product in the original container with the lid tightly closed at between 10 and 30°C in low humidity conditions away from direct sunlight. Kept under these conditions, the product may be used up to the date of expiry shown on the product label.

Ordering information

The Iron Sulfite Agar (ISA) (ISO 15213-1) is recommended for the enumeration of sulfite-reducing Clostridium spp.

Meat-Liver Glucose 0.6% Agar is suitable for sterility tests of pharmaceutical products and canned foods

E.E. Broth is recommended as an enrichment medium when examining food and feedstuffs for Enterobacteriaceae.
It is a modification of Brilliant Green Bile Broth, with an improved buffering capacity to encourage early growth and prevent autosterilization.

E.E. Broth uses glucose instead of lactose to make the medium a test for all enterobacteria including non-lactose fermenting organisms.
This formulation complies with the Harmonized USP/EP/JP.

Nitrogen is supplied by the gelatin peptone whilst glucose serves as the fermentable carbohydrate source.
Oxbile and brilliant green are the selective agents helping to suppress Gram-positive non- target organisms.
Auto sterilisation is prevented through the buffer system composed of potassium dihydrogen phosphate and disodium hydrogen phosphate.

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 and vitamin source in the medium. Glucose is the carbon energy source that facilitates organism growth and sodium chloride maintains osmotic balance. Di-potassium hydrogen phosphate is a buffering agent to prevent auto-sterilisation due to acid production during the growth of some organisms.
Tryptone Soya Broth is also commonly referred to as Soybean-Casein Digest Medium or Tryptic Soya Broth and is abbreviated as TSB. TSB conforms to the Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EU), and Japanese Pharmacopoeia (JP).

Kligler iron agar is used to differentiate between some of the enterobacteriacae on the basis of three reactions: fermentation of lactose and glucose and the production of hydrogen sulphide.
Kligler iron agar is a modification of the original formulation developed by Kligler.
It incorporates the principles of Russell’s double sugar agar with Kligler ‘s lead acetate agar.
The peptone provides the required nitrogen, carbon and vitamins. Lactose and glucose are carbohydrates.
Acid production from their fermentation is detected by the phenol red pH indictor. Sodium thiosulphate is reduced to hydrogen sulphide which is detected by the ferric citrate indicator.
Sodium chloride maintains the osmotic balance.

Slanetz and Bartley Agar is a selective medium used for the enumeration of intestinal enterococci in drinking water, beverages, waste water, swimming pool water and various biological products of animal origin, by the membrane filtration method. 

Ethyl Violet Azide Broth (also known as Litsky broth) is used to carry out the confirmation test of the detection and enumeration of fecal streptococci (enterococci) in drinking water and waste water, in frozen foods and other food products by the most probable number method. The procedure involves two stages : 
      – presumptive test in Azide Dextrose Broth (Rothe)
      – confirmation in Ethyl Violet Azide Broth (Litsky)

Bile Esculin Azide Agar (BEA agar) is a selective medium used to isolate and enumerate enterococci in food and pharmaceutical products. It is also used for the enumeration of enterococci animal feed.

Azide Dextrose Broth (Rothe) is used for the enumeration of enterococci in drinking water, frozen foods and other food products by the most probable number method

Tryptone-Soy Agar, used as a base to be supplemented with blood, is prepared with selected starting materials which do not turn brown. It was specially designed to detect beta-hemolytic reactions and to favor the growth of particularly fastidious aerobic and anaerobic bacteria. 
The media can be used for the hemolysis test on presumed colonies of Bacillus cereus, according to the standard ISO 21871.

BCP Dextrose Tryptone Agar (also known as BCP Glucose agar) is used to enumerate mesophilic and thermophilic aerobic bacterial spores (especially Bacillus stearothermophilus, responsible for flat sour) in raw materials and in ingredients used in canning non-acid products (pH > 4,5). It is also used in surface samples and canning process water.
