Opis

General description

Yeast extract is an extract of autolyzed yeast cells. Yeast extract is a mixture of amino acids, peptides, water soluble vitamins and carbohydrates and can be used as additive for culture media. It is a non-animal and low endotoxin peptone suitable for use in fermentations media for cultivation and resuscitation of a large variety of fastidious microorganisms. It is rich in vitamins and other nutritive substances and so, recommended for general laboratory media

Application
