Figure 2:(a) Growth profile of P. putida CSV86 on PA (○) and 4-HPA (●); (b) Time-dependent spectral changes during the enzyme reactions performed with 3,4-DHPA for the cell-free extract prepared from P. putida CSV86 grown on 4-HPA. Spectral scans were recorded every 45 sec; (c) Growth (●) vs specific activities of 4-HPAH (gray bars) and 3,4-DHPADO (white bars) from P. putida CSV86 grown on 4-HPA. Note the scales on the X and Y-axes.
