FIG. 2.

(A) Growth of 10403S and NCTC 7973 in LB medium supplemented with various sugars. Overnight cultures were grown in LB medium buffered with 100 mM MOPS (pH 7.0) and were diluted 1:25 into fresh medium with or without either glucose or cellobiose at 25 mM. The results of one representative experiment are shown. Similar results were obtained in three independent experiments. OD₆₀₀, optical density at 600 nm. (B) Doubling times of 10403S and NCTC 7973 in buffered LB medium with different carbon sources. Data represent means ± standard errors of the means for three independent experiments.
