Yeast extract is obtained from selected autolyzed Saccharomyces cerevisiae cells. This product can be used in preparing microbiological culture media providing readily available soluble vitamins (notably B-complexes), amino acids, peptides, and other essential growth factors. Yeast extract is observed as an animal free source and is therefore used extensively in many non-animal cell culture formulations. -
Yeast extract agar is a nutrient rich medium for the cultivation of non-fastidious bacteria, yeasts and moulds. Recommended for the plate count of microorganisms in water and dairy products. The yeast extract and peptone acts as a source of nitrogen, amino acids, carbon and vitamins. Related Supplements : LS0019 Oxytetracycline Selective Supplement

Originally intended for use in surface counting and pour plating techniques in food and dairy products this medium can be used as a general-purpose medium for the cultivation of most non-fastidious organisms. -
This is a selective medium for the isolation and enumeration of yeasts and moulds in dairy products. It is in according to a typical formulation of The International Organisation for Standardisation (ISO). Yeast extract acts as a source of nitrogen, carbon and vitamins in this medium. Glucose is a fermentable carbohydrate. Although the medium has a low pH it is made more selective by the inclusion of chloramphenicol, an antibiotic selective agent.

This is a selective medium for the isolation and enumeration of Yersinia spp. in clinical and food samples. It is made selective by the inclusion of Sodium desoxycholate, Crystal violet and the antimicrobials Cefsulodin, Novobiocin and Irgasan. Mannitol is also included which Yersinia ferments giving a colony that produces a ‘Bull’s Eye’ appearance. The majority of other enteric organisms are inhibited but if they do grow they produce a large pinkish colony with an opaque halo. -
