Metabolic regulation in glucose-limited chemostat cultures of Escherichia coli.
Glucose-limited chemostat cultures of Escherichia coli, growing at dilution rates above 0.3/hr, continue to grow at the restricted rate after removal of glucose restriction. In a glycogenless strain, the specific rates of increase of mass, protein, and ribonucleic acid (RNA) were equal before and after supplementation with 0.05% glucose and did not increase detectably until after 30 to 60 min. ...
متن کاملStarvation response of Saccharomyces cerevisiae grown in anaerobic nitrogen- or carbon-limited chemostat cultures.
Anaerobic starvation conditions are frequent in industrial fermentation and can affect the performance of the cells. In this study, the anaerobic carbon or nitrogen starvation response of Saccharomyces cerevisiae was investigated for cells grown in anaerobic carbon or nitrogen-limited chemostat cultures at a dilution rate of 0.1 h(-1) at pH 3.25 or 5. Lactic or benzoic acid was present in the g...
متن کاملComparative proteome analysis of Saccharomyces cerevisiae grown in chemostat cultures limited for glucose or ethanol.
The use of chemostat culturing enables investigation of steady-state physiological characteristics and adaptations to nutrient-limited growth, while all other relevant growth conditions are kept constant. We examined and compared the proteomic response of wild-type Saccharomyces cerevisiae CEN.PK113-7D to growth in aerobic chemostat cultures limited for carbon sources being either glucose or et...
متن کاملInfluence of the RelA Activity on E. coli Metabolism by Metabolite Profiling of Glucose-Limited Chemostat Cultures
Metabolite profiling of E. coli W3110 and the isogenic DrelA mutant cells was used to characterize the RelA-dependent stringent control of metabolism under different growth conditions. Metabolic profiles were obtained by gas chromatography-mass spectrometry (GC-MS) analysis and revealed significant differences between E. coli strains grown at different conditions. Major differences between the ...
متن کاملOverproduction of threonine aldolase circumvents the biosynthetic role of pyruvate decarboxylase in glucose-limited chemostat cultures of Saccharomyces cerevisiae.
Pyruvate decarboxylase-negative (Pdc(-)) mutants of Saccharomyces cerevisiae require small amounts of ethanol or acetate to sustain aerobic, glucose-limited growth. This nutritional requirement has been proposed to originate from (i) a need for cytosolic acetyl coenzyme A (acetyl-CoA) for lipid and lysine biosynthesis and (ii) an inability to export mitochondrial acetyl-CoA to the cytosol. To t...
