Abstract: | A numerical analysis of experimental growth curves obtained for Nitrobacter by observing changes in cell numbers, substrate concentration and rate of heat evolution has allowed the calculation of the growth rate constants during the phase of balanced growth. The molar growth yield was smaller during that phase than during the phase preceding it. On the other hand, the rate of heat evolution was larger during exponential growth by a factor of about 1.5 than during the stages up to and including this phase. The two observations being in agreement since, if less efficient synthesis occurs during exponential growth, more free energy must be dissipated as heat. |
