General description
Yeast extract granulated is manufactured from selected strains of Saccharomyces cerevisiae. It is manufactured under controlled conditions to retain its vitamin content and other nutritive values, such as peptides, free amino acids, nucleic acids, minerals, trace elements, and phosphorous compounds. It is rich in vitamins and is often used to supply these factors in culture media at a concentration of 0.3 - 0.5%. Yeast extract provides a complete source of nutrients for microorganisms and is particularly useful for the cultivation of fastidious bacteria that require specific nutrients or additional growth factors. It can be used alone or in combination with other sources of nutrients, such as peptones or salts.
Application
Yeast extract 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.
