Opis ogólny

Lennox 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 in a low-salt formulation. The addition of agar provides a solid medium for microbial growth.

Zastosowanie

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, including those that require low-salt conditions, such as Zeocin®.

Cechy i korzyści

Lennox EZMix powder with agar provides:
  • A budget-friendly alternative to pre-poured plates
  • Granulated, dust-free format for safer handling and faster mixing
  • Convenient small package to eliminate weighing
  • Easy scale-up using larger package sizes
  • Standard formulation

Uwaga dotycząca przygotowania

1. Suspend 35.6 g in 1 L of distilled water.
2. Heat to boiling while stirring to dissolve all ingredients completely.
3. Autoclave for 15 minutes at 121°C.
To prepare Lennox L Agar: Add 1 g glucose and proceed with preparation instructions as above.
To prepare the medium of Enquist and Sternberg: Aseptically add 10 ml of sterile 1 M magnesium sulfate after autoclaving.

Rekonstytucja

Add 35.6g powder in 1L water. Heat to boiling while stirring to dissolve powder. Autoclave for 15 minutes at 121C to sterilize. Allow to cool slightly before making additions, such as antibiotics (if desired). Pour into petri dishes and allow to solidify.

Questions

1–5 of 5 Questions  
  1. Will adding magnesium to the culture medium increase cell density?

    1 answer
    1. 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.

  2. Which bacterial culture medium is the best choice for my application?

    1 answer
    1. 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.

  3. What are the differences among the Luria, Lennox and Miller LB formulations?

    1 answer
    1. 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).
