General description
Peptone from casein is widely used in industrial microbiology as a nutrient source for the growth of microorganisms in large-scale fermentation processes. Peptone from casein, also known as tryptone or peptic casein peptone, is a water-soluble protein hydrolysate obtained from the pancreatic digestion of casein and used as a nutrient source in microbial culture media. It provides a wide range of nutrients, including amino acids, vitamins, minerals, and peptides, which support the growth of diverse microorganisms. It is particularly useful for the cultivation of fastidious and heterotrophic microbes that require complex nutrient sources.
Application
Peptone from casein 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, food and beverage samples.
Features and Benefits
Our Granulated media are:
- Safer - Significant reduction of inhalation of toxic and allergenic substances resulting in fewer allergic responses. Less contamination of working tools and environment
- Accurate - No separation of components and no clumping, even under humid or warm conditions, ensure a uniform product with higher performance accuracy
- Fast - Rapid and uniform dissolution in water
- Easier - Easier handling and weighing due to the better flow properties. Media do not stick to the flask or container
- Reliable - Homogenous distribution of ingredients guarantees high reproducibility even if only small amounts of media are used.
