FIG. 4.
UV spectra resulting from the conversion of 0.6 mM p-coumaric acid by induced whole cells of LPNC8 (0.2 g/liter) or LPD1 (5 g/liter) incubated 1 h without glucose in 25 mM phosphate buffer. t0, UV spectra corresponding to the sample taken at the start of kinetic reaction. t1, UV spectra corresponding to the sample taken after 1 h of kinetic reaction. (a) LPNC8 induced with p-coumaric or ferulic acid (1.2 or 3 mM); (b) LPD1 induced with 1.2 mM p-coumaric acid; (c) LPD1 induced with 3 mM p-coumaric acid.
