W.L. Nutrient Agar 1086 Condalab

WL Nutrient Agar, based on the Green and Grey formulation, is used for the control of industrial fermentations, particularly the manufacturing of beer. With a pH of 5.5, true counts of beer yeasts can be made and with a pH of 6.5, the medium is ideal for bakery and distilled spirit yeasts. Tryptone provides nitrogen, vitamins, minerals, and amino acids essential for growth. Dextrose is the fermentable carbohydrate providing carbon and energy. Yeast extract is a source of vitamins, particularly of the B-group and monopotassium phosphate is the buffer. Potassium, Calcium and Ferric chlorides all provide essential ions for the osmotic balance. Magnesium and Manganese sulphates are sources of divalent cations. Bromocresol green is the pH indicator and bacteriological agar is the solidifying agent.
