Description
Yeast extract, micro-granulated, for bacteriology is a classic nutrient component for microbiological culture media and related life-science applications. Identified under CAS number 8013-01-2 and EG nr. 232-387-9, it provides a rich source of vitamins, peptides and growth factors commonly used in media for bacteria and other microorganisms. The micro-granulated form aids handling and dissolution during media preparation. Physical data include a density of 1,22 g/cm³ and a boiling point of 105 °C. This yeast extract from manufacturer Carl ROTH is positioned among basic reagents for nutrient media and extracts. Laboratories use it in standard recipes for enrichment, selective and general-purpose media where a consistent yeast-extract base is required. Prepare and store according to established protocols and the accompanying documentation for reliable culture performance.
