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.

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).

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.
