Fig. 22. — Growth rate of B. ramosus at different temperatures. 



The data of Ward are computed in Table 56, as 

 growth rate constants (see p. 190). These constants are 

 plotted in Fig. 22. It shows the asymptotical approach 

 to zero of the rate of growth at low temperatures, and the 

 abrupt approach to zero at high temperatures.
