Transcriptional profiles of steady-state chemostat cultures were measured at a range of oxygen levels using microarrays. Oxygen levels were defined by the aerobiosis scale of Alexeeva et al. (2002).

This .csv file contains the filtered datset of the aerobic to anaerobic transition. Values are shown if they show a statistically significant change relative to the 0 minute transcriptional profile (t-test p<0.05 and 2-fold cut-off).

This is a pdf showing a graph of the dissolved oxygen tension of the culture during an aerobic to anaerobic transition.

This is a pdf showing a graph of the dissolved oxygen tension of the culture during an anaerobic to aerobic transition.

This .csv file contains the entire transcriptional dataset of the aerobic to anaerobic transition. The values shown are the gene-expression ratio at 2, 5, 10, 15 and 20 minutes relative to the 0 minute timepoint.

This .pdf file shows a graphical representation of the physiological measurements from the Sheffield Infors chemostat which were made during acetate calibration and also when sampling for the steady-state transcriptional profiles.

This .csv file contains growth parameters measured from chemostat runs of the Sheffield Infors chemostats. The runs were carried out for acetate calibration purposes and for sampling for the steady-state transcriptional profiles.
