General description

Liquid media is also termed as broth. It has nutrients dissolved in water. Luria-Bertani broth (LB broth) is used in naphthalene degradation experiments.

Application

LB Broth has been used to culture P. aeruginosa.
Suitable for non-selective cultivation of E. coli strains for cloning, DNA plasmid production and production of recombinant proteins. Also suitable for selective cultivation when appropriate antibiotics are added.

Biochem/physiol Actions

LB Lennox media is a highly-referenced microbial growth medium used for the cultivation of E. coli. This nutrient-rich microbial broth contains peptides, amino acids, water-soluble vitamins, and carbohydrates.
