Descrição geral
Miller′s LB 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.
Aplicação
LB Broth (Miller) has been used as a culture medium for E coli,[1] Pseudomonas putida KT2440,[2] Vibrio parahaemolyticus,[3] and soil samples for the isolation of Bacillus spp.[4]
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.

Ações bioquímicas/fisiológicas
Luria Broth is used for maintenance and propagation of Escherichia coli. The E. coli grow faster in Luria Broth because the tryptone and yeast supply essential growth factors that the E. coli would otherwise have to synthesize. Luria Broth also contains essential electrolytes for transport and osmotic balance, due to the NaCl component[5].
Características e benefícios
Miller′s LB powder provides:
- Easy scale-up using larger package sizes
- A budget-friendly alternative to liquid
- Standard formulation
Nota de preparo
1. Suspend 25 g in 1 L of distilled water.
2. Autoclave for 15 minutes at 121 °C.

What are the differences among the Luria, Lennox and Miller LB formulations?
1 answer-
LB, (originally termed lysogeny broth) was initially composed of tryptone, yeast extract, NaCl and glucose. Soon after, the glucose was omitted (Miller's version), and later the NaCl content lowered by half (Lennox's version). For some applications, even lower salt is required (Luria's low salt version).

Which bacterial culture medium is the best choice for my application?
1 answer-
Each of the broths will likely grow E. coli very well, but there are still general guidelines for choosing a broth when you are working without a protocol. Generally:LB - Miller and LB - Lennox are used for E. coli growth and maintanence, DNA plasmid production and protein production. The Lennox formulation has a lower salt content required for some salt-sensitive selection antibiotics.LB - Luria low salt is used for special applications where the E. coli growth or other constraints require the lowest possible salt content.Terrific Broth is used for higher yield protein production and high yield DNA plasmid production, because of the faster growth of the E. coli in this medium.SOB is used for protein production, DNA plasmid production and the generation of high-efficiency competent cells.SOC is used for initial growth of competent cells and the transformation procedure.

Will adding magnesium to the culture medium increase cell density?
1 answer-
In microbial broth formulations that do not already contain magnesium, the addition of 10-20 mM MgCl2 or MgSO4 may increase cell densities. You may need to also increase the shaking speed of the incubator.
