Performance of evolved and ancestral clones to utilize alternative carbon substrates. Carbon utilization was measured for 95 different carbon substrates. Performance was quantified as the area under the growth curve for each individual carbon substrate (OD₆₀₀ vs. time), which takes into account both growth rate and yield. Data are presented as histograms. (a) Comparison of clones evolved at pH 7.5 with ancestral populations at pH 7.5; (b) comparison of clones evolved at pH 6.5 with ancestral clones at pH 6.5; (c) comparison of ancestral clones at pH 6.5 with ancestral clones at pH 7.5; (d) comparison of clones evolved at pH 6.5 with clones evolved at pH 7.5
