Beschreibung

General description

Yeast extract is the water-soluble portion of autolyzed yeast, often used in culture media. Yeast extract contains a mixture of amino acids, peptides, water soluble vitamins and carbohydrates.
Yeast extract is used in all solid media, on which stock cultures are maintained, due to its ability in promoting growth of most bacterial contaminants, thereby making them visible to identify. Yeast extract does not enhance the growth of wild-type cells but essential for auxotrophic mutants.

Application

Für bakteriologische Anwendungen mit verschiedenen Mikroorganismen

Hefeextrakt wird bei einer Vielzahl von Mikroorganismen und molekulargenetischen Anwendungen als bakteriologische Medienkomponente eingesetzt.

Select Yeast Extract has been used:

• as a supplement in the minimal sporulating medium (MSL) for the secretory production of human tumor necrosis factor-α (TNFα) using the carboxypeptidase Y (Cpy) signal peptide.
• in the isolation of halophilic archaea.
• as a component of microbial growth medium for cultivation of marine bacterial strain Zobellia uliginosa.
  
  Suitable for use as nutritional source in microbial media.

Other Notes

Wasserlöslicher Teil von autolysierter Hefe mit intakten B-Vitaminen. Hefeextrakt ist eine Mischung aus Aminosäuren, Peptiden, wasserlöslichen Vitaminen und Kohlenhydraten und kann als Additiv für Nährmedien verwendet werden.
