Abstract

Isothermal reaction calorimetry was employed on the bench scale to measure the enthalpy efficiency and O2 efficiency of growth of several microbial strains cultured on a range of substrates with varying degrees of redn. The obsd. values of these energetic efficiency factors agreed well with simple theor. predictions based solely on the degree of redn. of the substrates as independent variable. Calorimetry is thus shown to be a useful tool for investigations of microbial growth energetics. Measuring heat dissipation in large scale bioreactors provides online information on the energetics of growth and should therefore be useful for process control purposes. [on SciFinder (R)]

Calorimetry

In chemistry and thermodynamics, calorimetry () is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, or phase transitions under specified constraints. Calorimetry is performed with a calorimeter. Scottish physician and scientist Joseph Black, who was the first to recognize the distinction between heat and temperature, is said to be the founder of the science of calorimetry.

Calorimeter

A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber. It is one of the measurement devices used in the study of thermodynamics, chemistry, and biochemistry.

Differential scanning calorimetry

Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Generally, the temperature program for a DSC analysis is designed such that the sample holder temperature increases linearly as a function of time.
