General description
Yeast Nitrogen Base is a highly-referenced growth medium used for the cultivation of yeast. This nutrient-rich microbial broth contains amino acids, nitrogen, vitamins, trace elements and salts.
Application
Yeast Nitrogen Base With Amino Acids has been used:
Suitable for use in classifying yeasts based on carbon requirements. Also suitable for general growth of yeasts with the addition of a carbon source (usually glucose).Yeast nitrogen base with amino acids is a satisfactory nitrogen source for general growth media. Contains all essential nutrients required for the growth of yeasts except carbohydrate.
- in the ZYP-31 media preparation for E.coli
- in synthetic dextrose (SD) medium to evaluate the influence of nitrogen source
- to culture Candida utilis for the production of 13C-labeled yeast extract as internal standard
- in the preparation of imaging medium

Reconstitution
Make a 10x concentrated stock solution by stirring to suspend 6.7g yeast nitrogen base powder and 5 g glucose in 100 mL water. Warm if necessary to aid solubilization. Filter sterilize and store at 2-8°C.
Dilute the 10x concentrated stock to a 1x working solution by adding 100mL concentrated stock to 900mL sterile water.
