General description

Lennox LB是一个被高度引用的用于 大肠杆菌培养的微生物生长培养基。这种富含营养的微生物肉汤含有肽、氨基酸和低盐配方的碳水化合物。

Application

Luria肉汤被用于大肠杆菌(Escherichia coli)的维持和繁殖。 大肠杆菌在Luria肉汤中生长得更快,因为胰蛋白胨和酵母为其提供了必需的生长因子,从而无需大肠杆菌自身合成。由于含有NaCl成分,Luria肉汤还含有转运和渗透平衡所必需的电解质。
在三鞭毛虫细胞提取物的分级研究中,它被用于梨形四膜虫胞级分的重悬。
适用于 大肠杆菌 菌株的非选择性培养,用于克隆、生产DNA质粒和生产重组蛋白。 也适用于添加适当抗生素时的选择性培养,包括需要低盐条件的抗生素,如吉欧霉素®

Features and Benefits

Lennox LB粉末可提供:
  • 便捷式小包装,无需称重步骤
  • 使用大包装可轻松放大规模
  • 一种预算较低的液体替代品
  • 标准配方

Preparation Note

1.将20 g悬浮于1L蒸馏水中。
2.121 °C下高压灭菌15分钟。
制备LB肉汤:添加1 g葡萄糖,然后按照上述说明操作。
制备Enquist &Sternberg培养基:高压蒸汽灭菌后,以无菌操作加入10 mL无菌1M硫酸镁。

Bacteria can damage sperm and thus reduce the reproductive success of both males and females; selection should therefore favour the evolution of antimicrobial protection. Eusocial hymenopterans might be particularly affected by such bacterial infections because of their mating ecology. In
