W2002 is used for the cultivation of yeasts, molds, and bacteria encountered in brewing and industrial fermentations. W-L Nutrient Agar is not intended for use in the diagnosis of disease or other conditions in humans

W-L Nutrient Medium was developed by Green and Gray while studying various fermentation processes. An exhaustive study examining methods of fermentation control procedures in worts, beers, liquid yeasts and similar fermentation products led to the development of W-L Nutrient Medium. At a pH of 5.5, counts of viable baker?s yeast will grow on W-L Nutrient Medium. W-L Nutrient Medium is also referred to as ?Wallerstein Laboratory Medium?.
