Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A simple definition of the energetic growth efficiency both in terms of enthalpy and free energy is given and discussed. In cultures growing by respiratory catabolism, these efficiencies may conveniently be obsd. online by isothermal reaction calorimetry. ...
Synchronized oscillating cultures of Saccharomyces cerevisiae CBS 426 exhibit periodic oxidoreductive metab. The changing metab. is detectable by in situ heat-flux calorimetry in the BSC 81, which was operated as a chemostat in these expts. The measured me ...
In addn. to online detection of events in biotechnol., calorimetry could be used to control processes. In the latter case, a correct and instantaneous heat signal must be available. This would be possible only if a correct evaluation of baseline evolution ...
Chemostat cultures of an aerobic fermenting yeast (Saccharomyces cerevisiae) and an aerobic respiring yeast (Kluyveromyces fragilis) were grown under dual C + N limitation in an isothermal reaction calorimeter. The dual limitations resulted in uncoupled ox ...
A review with 75 refs. of calorimetric techniques used and results obtained in calorimetric expts. aimed at developing quant. relation between heat release and other important process parameters for potential use in monitoring and controlling tech. bioproc ...
Measurements of the heat produced by Saccharomyces cerevisiae CBS 426 were used in conjunction with elemental and enthalpic balances to control fed-batch fermns. A proportional control using the ratio of carbon dioxide evolution rate to heat prodn. resulte ...
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 ...

Heat produced by hybridoma suspension cultures was continuously monitored in a 2-L heat-flux calorimeter. Heat measurements reflected changes in the metabolic state of the culture under different aeration conditions. A highly anaerobic metab. was indicated ...
