General Description

Peptone from meat is widely used in industrial microbiology as a nutrient source for the growth of microorganisms in large-scale fermentation processes. Peptone from meat, also known as peptic meat peptone, is a water-soluble protein hydrolysate obtained from the pancreatic digestion of meat 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 meat 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. The high sulphur content makes meat peptone suitable for the detection of bacteria producing hydrogen sulfide.

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.
