3-3 Experimental Observations

Cooney and co-workers collected heat release experimental data for a number of different organisms by making careful heat balance measurements over a fermentor. The data show a linear relationship between heat released and oxygen consumption rate (Fig 2-1).

Figure 3-1 Experimental Heat Release Data (after Cooney et al )

The slope of the line above is equal to the amount of heat released per mol of oxygen consumed. That is:

This result enables one to calculate heat generation rate from oxygen uptake rate information. We will examine oxygen uptake rate data in Chapter 5.
