FIG. 4.

Time courses for the concentrations of morpholine (×), glycolate (▵), and 2-(2-aminoethoxy)acetate (□) during the degradation of morpholine (10 mM) by M. aurum MO1 cells at 100 g · liter⁻¹. The quantification was made by integrating the signals in ¹H-NMR spectra relative to the area for the reference TSPd₄ (see Fig. 2). (Inset) Data from five independant experiments concerning the degradation of morpholine; a polynomial calculation was used to plot the final curve.
