General description
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
- 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.
