TranscriptomicsDegeneration of penicillin production in ethanol-limited chemostat cultivation of Penicillium chrysogenum: A systems biology approach
In microbial production of non-catabolic products, a loss of production capacity upon long-term cultivation (for example, chemostat), a phenomenon called strain degeneration, is nearly always observed. In this study, a systems biology approach (monitoring changes from gene to produced flux) was used...

TranscriptomicsTranscription profiling of S. cerevisiae grown in acetate, ethanol and maltose limited conditions to investigate transcriptional regulation in controlling fluxes in central carbon metabolism
In contrast to batch cultivation, chemostat cultivation allows the identification of carbon source responses without interference by carbon-catabolite repression, accumulation of toxic products, and differences in specific growth rate. This study focuses on the yeast Saccharomyces cerevisiae, grown ...

TranscriptomicsTranscription profiling of S. cerevisiae treated with absence of oxygen or depletion of ATP to investigate control of glycolytic enzyme fluxes
Metabolic fluxes may be regulated "hierarchically," e.g., by changes of gene expression that adjust enzyme capacities (V(max)) and/or "metabolically" by interactions of enzymes with substrates, products, or allosteric effectors. In the present study, a method is developed to dissect the hierarchical...
