Figure 4.

Comparison of signal intensities relative to noise in 1D-HNCO slices. The importance of adding the fractional quantity of u-¹³C-glucose during log phase growth is supported by two independent trials in which the cultures were each induced at a stage that exhibited the onset of rollover (trials 7 (512 transients) and 8 (384 transients), Table 1). These trials yielded just 12–13% incorporation using 10%^w/w enriched glucose. Open symbols indicate the time of induction.
