Description

General description

Yeast peptones serve as a complex nitrogen source and contain growth factors such as active peptides, amino acids, vitamins, sulfur compounds, and nucleotides. They are a source of phosphorus, which is essential for energy storage and distribution within the cell. They also contain minerals and trace elements, for example, zinc, iron, potassium, sodium, calcium, and magnesium, that activate metabolic reactions. As yeast-based nutrients (YBN), yeast peptones do not contain animal-derived material and are thus free of human and animal pathogens. They are also free from GMO material and allergens and have a lower CO₂ footprint than peptones of animal origin.

Application

Yeast Peptone 4 (powder) is suitable for making complex culture media for industrial fermentations (e.g., probiotics production), microbiology applications, and cell cultures. It is used during microbiological QC, especially for environmental monitoring and aseptic process simulations (media fill trials).

Features and Benefits

Advantages of yeast peptones over animal and plant-derived peptones:

• No animal-derived material
• Free of animal and human pathogens
• Free of allergens, pesticides, and GMO material
• No ethical or HALAL issues
• Greater batch consistency
• Greater flexibility thanks to modifiable specifications
• Lower CO₂ footprint
• No need for import and export permits

Other Notes

The pH range, total and amino nitrogen content, distribution of peptide sizes, and growth promotion abilities depend on the yeast peptone product selected. The choice of product makes it possible to influence parameters such as microbial growth, biomass, metabolite production, acidity, cell viability, or cell resistance in the downstream process.
