Escherichia coli Physiology in Luria-Bertani Broth

Institut Jacques Monod, CNRS, Université Paris 6, Université Paris 7, F-75251 Paris Cedex 05, France

Received 22 August 2007/ Accepted 14 September 2007

Luria-Bertani broth supports Escherichia coli growth to an optical density at 600 nm (OD₆₀₀) of 7. Surprisingly, however, steady-state growth ceases at an OD₆₀₀ of 0.3, when the growth rate slows down and cell mass decreases. Growth stops for lack of a utilizable carbon source. The carbon sources for E. coli in Luria-Bertani broth are catabolizable amino acids, not sugars.
