FIG. 6.

In vivo ¹³C NMR spectra of an M. phosphovorus cell suspension under aerobiosis. Following the experiment whose results are shown in Fig. 4, air was provided at time zero and spectra were acquired at regular time intervals. The upper spectrum was acquired in the beginning of this aerobic phase, and the lower spectrum was acquired towards the end of this phase. Tre, trehalose; Glu, glutamate; Ac, acetate; Gly-C₁, glycogen C-1.
