General description
Hefeextrakt wird von verschiedenen Hefearten produziert, hauptsächlich von Saccharomyces cerevisiae oder Bäckerhefe. [1] Neben seiner Anwendung als Supplement für Kulturmedien in der mikrobiellen Forschung und Biotechnologie wird Hefeextrakt [1] auch als Bestandteil komplexer Medien für industrielle Fermentationen sowie[2]als Nährstoffquelle für verschiedene mikrobielle Medien eingesetzt.
Application
Für bakteriologische Anwendungen mit verschiedenen Mikroorganismen
Hefeextrakt wird bei einer Vielzahl von Mikroorganismen und molekulargenetischen Anwendungen als bakteriologische Medienkomponente eingesetzt.
Hefeextrakt wird eingesetzt als Bestandteil von:
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.
