This paper attempts to review in how far thermodn. anal. can be used to understand and predict the performance of microorganisms with respect to growth and bioproduct synthesis. In the first part, a simple thermodn. model of microbial growth is developed w ...
A novel reactive perstraction system has been developed based on liq.-core capsules, involving an enzyme-catalyzed reaction coupled with simultaneous in situ product recovery. Lipase-catalyzed reactions, hydrolysis of triprionin and nitrophenyl laurate, we ...
The activity of penicillin acylase has been studied in aq. and org. solvents, as free enzyme as well as immobilized within the membrane of liq.-core capsules. The activity of the enzyme is inhibited by the accumulation of the products of the hydrolysis rea ...
A new approach combining electrostatic and covalent bonds was established for the formation of resistant capsules with long-term stability under physiol. conditions. Three kinds of interactions were generated in the same membrane: (1) electrostatic bonds b ...
The driving force for organo- or lithotrophic growth as well as for each step in the metabolic network is the Gibbs reaction energy. For each enzymic step it must be neg. Thermodn. contributes therefore to the in-silico description of living systems. It ma ...
Bench-scale biocalorimetry (>=1 L) allows for the detn. of the metabolic heat flow during bioprocesses under complete control of all process conditions for extended periods of time. It can be combined with a no. of online and off-line measurement technique ...
