Fig. 4
A comparison of steady-state production level of ethanol vs. acetate (a), pyruvate (b), hydrogen (c), total amino acids (d) and cell nitrogen (e, a proxy for cell biomass) for strain lineages 1 and 2. f Shows data for cell carbon to cell nitrogen for the same data set for every strain. Strains with wild-type pta are represented by round shaped dark blue data points, strains with pta deleted (unmarked deletion or merodiploid) are square shaped light blue data points and strains with pta deleted but evolved for improved growth are diamond shaped blue data points. The evolved strains with pta deleted (LL374, LL375, LL1011 and LL1043) are indicated with their strain name as is wild-type (LL1004). Error bars represent one standard deviation, n ≥ 4. This figure does not include data for strains LL1111, LL1160 and LL1161, and the data used here is not normalized for differences in cellobiose feed concentration or for measured dilution rate
