Microcalorimetry studies of energy changes during the growth of Klebsiella aerogenes in simple salt/glucose media. 2. Enthalpy of aerobic growth.
Power-time traces for cells of K. aerogenes growing aerobically in batch culture with glucose limitation are reported and the results discussed with the corresponding mass balance data. Enthalpy values during the consumption of glucose and production of cellular material are calculated during growth in glucose (concentration range 0.56-5.4 mmol dm-3). The efficiency of caloric conversion and energy requirements during growth are considered by two methods. The measured enthalpy (delta hgluc) is significantly lower than the theoretical value, (delta Hox). The difference in the values is considered o be a measure of the enthalpy of growth (delta HB) and accounts for 5-15% of the initial substrate energy present.
