Description
Yeast extract is a powdered nutrient preparation for bacteriology, widely used as a rich source of peptides, amino acids, vitamins and growth factors in microbial culture media. It is identified by CAS number 8013-01-2 and EG number 232-387-9, with a density of 1,22 g/cm³ and a boiling point of 105 °C. This yeast extract from manufacturer Carl ROTH supports media formulation in research, quality-control and teaching laboratories, including genetic engineering and broader life-science applications where complex organic nitrogen sources are required. Consistent use of a defined bacteriological-grade extract helps standardise growth conditions across batches of media. size is practical for routine media preparation without excessive bulk storage. Specify this powdered yeast extract whenever bacteriological media recipes call for a reliable yeast-derived nutrient component.

Questions about Yeast extract, powdered, for bacteriology, 250 g, plastic
What is this article?
Yeast extract, powdered, for bacteriology, 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Essential oils & fragrances, inside Natural products & essential oils, in Lab chemicals.
An essential oil is the volatile fraction distilled or pressed from a named plant part. The species, the chemotype and a stated component, when the seller gives one, are the specification. A fragrance compound is a formulated mixture. The two should not be treated as the same bottle.
A natural product is a molecule extracted from a plant, an animal or a microorganism, or a mixture of those molecules. An essential oil is the volatile fraction. The useful specification is the source species, the plant part and, where it exists, the stated content of a marker compound. Two oils with the same common name are not the same article. Marker compounds are identified on PubChem and named by IUPAC.
