说明

酵母提取物粉末由选定的酿酒酵母菌株制成。 推荐用于微生物培养基、发酵和其他生物学研究。 酵母提取物在受控条件下生产,以保留其维生素含量和其他营养价值,如肽、游离氨基酸、核酸、矿物质、微量元素和磷化合物。 它富含维生素,尤其是 B 复合物,通常用于在培养基中以 0.3 - 0.5% 的浓度提供这些因子。
酵母提取物特别用于培养基中用于培养牛奶或其他乳制品中遇到的微生物,以及用于检测和富集病原体和指示生物的培养基。

一般描述

Yeast Extract Powder is manufactured from selected strains of Saccharomyces cerevisiae. It is recommended for use in microbial culture media, fermentation and other biological studies. Yeast extract is manufactured under controlled conditions to retain its vitamin content and other nutritive values such as peptides, free amino acids, nucleic acids, minerals, trace elements, and phosphorous compounds. It is rich in vitamins, especially the B complex, and is often used to supply these factors in culture media at a concentration of 0.3 - 0.5%.
 

应用

Yeast extract is particularly used in media for the cultivation of microorganisms encountered in milk or other dairy products and in the media for the detection and enrichment of pathogens and indicator organisms.
