p.172 left column 2nd paragraph:"For heat output measurements E. coli was grown in nutrient broth on the surface of asbestos fiber in order to obtain good aeration conditions." p.172 right column 2nd paragraph:"The temperature differential was continuously
recorded on a 1 mv recorder and the outflowing air passed through a thermal conductivity type carbon dioxide analyzer, which recorded its concentration." p.172 right column 3rd paragraph:"Periodically, a small sample of asbestos was removed from the flask and the number of bacteria was estimated by vigorously shaking the sample with 100 ml of sterile Ringer's solution at 37°C for 2 min, and plating out at least three known dilutions on tryptone glucose extract agar medium (Difco)." p.173 left column top paragraph:"All heat output experiments were done in duplicate and never differed by more than 20 per cent." p.173 left column 2nd paragraph:"The water activity of broths was determined by a simple form of the isopiestic method of Robinson and Sinclair (1934)." |
| Comments |
"Table 1 [please see below table 2 in link] gives the composition, densities, and water activities of the broths used. Figure 1 shows typical curves for the heat output of broth A, B, E, and G, whereas figure 2 gives their carbon dioxide production. Table 2 shows the cell counts, total heat outputs, and heat output per cell in the same experiments early in the logarithmic phase and at the point of maximal heat output." |
