特點

Yeast extract | 酵母萃取物(yeast extract) |貨號MC001-A[1]

可以提高 E. Coli DH5α 密度(V.S. 傳統 LB broth )。Yeast extract 提供了豐富的營養成分，Saccharomyces酵母細胞經過自動分解(autolysate)後，除了富含各式微生物以及動物細胞生長所需的胺基酸氮源外，還有含量極高的可溶性維生素B群 (B vitamins)。包括 vitamins、amino acids、peptides 與 carbohydrates 等。其高營養價值也是胎牛血清 FBS 最佳替代物，是生物製程中極具重要性的非動物性蛋白之來源。因此培養基配方、微生物發酵原料、血清替代物、抗體生產與蛋白質藥物等都採用yeast extract作為營養來源。
