a Numbers in the brackets indicate pR' activity ranking with 1 being the highest and 5 being the lowest [50]; IN56 data is from Table 2.

b 100%LB data is from Table 2, strain IN56; DM, Davis minimal salts medium; Glc, glucose; Gly, glycerol.

C In some cases, the sample size n is the pooled number of cells observed across several days. Detailed information can be found in Table S2 of the addition file 1.
