Comments P.6663 left column 3rd paragraph: "In separate studies of E. coli grown in McIlvaine’s medium (primary source 33), glucose (primary source 34), or LB (primary source 35), for example, the concentrations of K+ were determined to be ∼250 (free), ∼180–200, and ∼100 mM, respectively." LB=Lysogeny broth (also known as Luria-Bertani broth)
