||P.667 right column 2nd paragraph: "Similarly, rapidly growing cells of E. coli B/r are wider than slowly growing cells, with cells having a generation time of 22 min being significantly wider (∼1 μm) than cells having a generation time of 72 min (∼0.5 μm) (primary source). However, not all strains respond the same way. For example, E. coli B/r becomes more elongated at higher growth rates, but E. coli B/r H266 becomes more rounded (primary source)."
