Descripción general

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.

Aplicación

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.
Yeast extract is used as a bacteriological media component for a variety of microorganisms and molecular genetics applications.

Otras notas

Water soluble portion of autolyzed yeast with intact B-complex vitamins. Yeast extract is a mixture of amino acids, peptides, water soluble vitamins and carbohydrates and can be used as additive for culture media.

A Gram-negative, arsenate-respiring and arsenite-oxidizing marine bacterium, NKSG1(T), was isolated from hydrothermal sediment at Santorini, Greece. Strain NKSG1(T) was a facultatively anaerobic, motile, non-spore-forming, rod-shaped bacterium. Growth occurred optimally at 35-40 degrees C, between pH 5.5 and 9.0 and with
