LB培养基
名稱
儘管該培養基的名稱被廣泛解釋爲Luria-Bertani 培養基,然而根據其發明人貝爾塔尼(Giuseppe Bertani)的說法,這個名字來源於英語的 lysogeny broth,即溶菌肉湯[1]。
配方
LB 培養基的配方發表於1951年有關溶源性的論文中。用於使志賀氏菌屬的細菌增長[1][2]。
LB培養基在1950年代曾被用作培養大腸桿菌的業界標準配方[3][4][5][6][7]。它還被廣泛應用於分子微生物學以及質體DNA的製備上,是重組大腸桿菌DNA時最常用的培養基[8]。但LB培養基不鼓勵應用於生理學研究上[9]。
每個LB培養基的配方不盡相同,但大概都會包含下列幾項:
一升水中加入:
1951年的原始論文中,貝爾塔尼在1公升的水中加入了10克的氯化鈉、1克的葡萄糖[6],但之後便剔除掉了葡萄糖。
氯化鈉的量經常隨細菌的生長需求不同而有所改變,像鹽分較低的Lennox和Luria培養基就適用於對於鹽分較敏感的抗生素實驗上[10]。
- LB-Miller (10 g/L NaCl)
- LB-Lennox (5 g/L NaCl)
- LB-Luria (0.5 g/L NaCl)
