詳細

詳細

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

アプリケーション

Yeast extract is recommended for use in culture media and for the mass cultivation of various microorganisms. It provides multi-functional nutrient supplements that can also be used in microbial fermentation.
