Universal peptone M 66 can be used as nutrient, for example as replacement of serum albumin in cell culture and fermentation. It is commonly used as an ingredient in many microbial culture media for the growth and identification of bacteria, yeasts, and molds from various pharmaceutical, environmental, and food and beverage samples.

Universal M 66 peptone is a poly peptone mixture of casein peptone, meat peptone and soy peptone, with well-balanced nutritional characteristics. Peptone M 66 is widely used in industrial microbiology as a nutrient source for the growth of microorganisms in large-scale fermentation processes. Peptone M 66 is a water-soluble protein hydrolysate obtained by the digestion of natural sources such as meat, casein, gelatin, or soy. It provides a variety of essential nutrients required for bacterial growth, including amino acids, vitamins, and minerals. It is useful for the growth of fastidious bacteria, yeasts, and molds.
