Table 1: Comparison of the proteome during chemostat growth of the initial cell clone and Population 1-3. The table illustrates the fraction of differentially expressed proteins for each comparison (log2 fold change > 0.5 or log2 fold change < -0.5, q-value < 0.05). Moreover, GO process terms, which based on a Fischer’s exact test, are enriched by proteins in a cluster of proteins with q-values <0.05 and log2 fold-change >0.5 are shown. In a comparison of two strains A vs. B, the protein levels of A is higher than the protein levels of B if log2 fold-change > 0. No differentially expressed GO-terms could be found for clusters of proteins with log2 fold-change <0.5 and q-values < 0.05 for any of the comparisons.
