The objective of this study was to characterize the dynamic adaptation of the oxidative capacity of Saccharomyces cerevisiae to an increase in the glucose supply rate and its implications for the control of a continuous culture designed to produce biomass ...
Continuous cultures of a hybridoma cell line (Zac3) were performed with 2 14C-labeled substrates: glucose and glutamine. A simplified network was used to describe cell metab. This simple network gave a good idea of the main fluxes into the cell, esp. for c ...
The pentose phosphate pathway and the pyruvate shunt were identified as major pathways of glucose catabolism in a recombinant, riboflavin-producing Bacillus subtilis strain. Reactions connecting the tricarboxylic acid cycle and glycolysis, catalyzed by the ...
Continuous cultivation in a glucose-limited chemostat was used to det. the growth parameters of wild-type Bacillus subtilis and of a recombinant, riboflavin-producing strain. Maintenance coeffs. of 0.45 and 0.66 mmol of glucose g-1 h-1 were detd. for the w ...
The difference between 1H nuclear magnetic resonance (NMR) spectra obtained from the human brain during euglycemia and during hyperglycemia is depicted as well-resolved glucose peaks. The time course of these brain glucose changes during a rapid increase i ...
A novel approach for indirect biomass detn. in case of non-const. specific metabolic rates is reported. Specific glucose consumption rate was detd. during a first calibration culture for both free suspended and immobilized cells. It was expressed as a line ...
The amt. of Vitreoscilla Hb (VHb) expression was modulated over a broad range with an isopropyl-beta-D-thiogalactopyranoside- (IPTG)- inducible plasmid, and the consequences on microaerobic Escherichia coli physiol. were examd. in glucose fed-batch cultiva ...
The estn. of the intracellular fluxes of mammalian cells using only the mass balances of the relevant metabolites is not possible because the set of linear equations defined by these mass balances is undetd. Either addnl. exptl. flux data or addnl. theor. ...
The aim of the present work was to investigate whether uncoupling of catabolism from anabolism, which was often obsd. in heterotrophic microorganisms under energy-sufficient growth conditions, also occurs in the autotrophic bacterium M. thermoautotrophicum ...
A tight coupling exists between neuronal activity and energy metabolism. Over a century ago Roy and Sherrington postulated that “the brain possesses intrinsic mechanisms by which its vascular supply can be varied locally in correspondence with local variat ...
