Note-primary source is source of fig.1 (on p.3). Abstract of primary source: "The adaptation of Escherichia coli B/r to temperature was studied by measuring the levels of 133 proteins (comprising 70% of the cell's protein mass) during balanced growth in rich medium at seven temperatures from 13.5 to 46 degrees C. The growth rate of this strain in either rich or minimal medium varies as a simple function of temperature with an Arrhenius constant of approximately 13,500 cal (ca. 56,500 J) per mol from 23 to 37 degrees C, the so-called normal range above and below this range the growth rate decreases sharply." |

P.1 3rd paragraph: "Most bacteria, including E. coli and S. typhimurium, can grow over a range of approximately 40°C. The growth rates of most wild-type strains of E. coli and S. typhimurium respond similarly to changes in temperature the particular response of E. coli B/r is shown in Fig. 1. The normal temperature range extends from 21 to 37°C, over which range µ has a value of 13,000 to 14,000 cal/mol (ca. 54,000 to 59,000 J/mol BNID 105004). The maximum temperature at which balanced growth can be sustained by this strain is approximately 49°C. The minimum temperature for sustained growth of E. coli ML30, and presumably other strains as well, lies between 7.5 and 7.8°C (BNID 105003)." |
