| Comments |
P.1580 left column 4th paragraph: "Direct measurements by electron microscopy (primary source) give a ratio of average length to average width of 4.4±0.6 for E. coli B/r H growing at rates of between 0.4 and 2.9 doublings per hour. There is some evidence (primary source) that the cell shape of this strain changes systematically with growth rate (the ratio of length to width changes from around 5 for the slowest growing cultures to about 3.5 for the fastest)." |
