LB Agar and LB Broth

Lennox & Miller Bacterial Culture Media

LB Broth (Lysogeny broth, Luria broth, Lennox broth, LB Agar or Luria-Bertani medium) is the most widely used nutritionally rich medium, for the culture and growth of bacteria.

LB Medium Composition
There are several different formulations of Lb broth, but the composition is generally the same comprising of peptides and casein peptones, trace elements, mineral and vitamins. Agar is a complex gelatinous carbohydrate, and is added to the LB broth, in order to form gel for bacteria to grow on as a microbial culture.

Our LB broth powders and liquids should be added to a plate (not included).
