Figure 4:Whole-cell oxygen uptake studies with P. putida CSV86. Cells were grown on: (a) PA, 0.1 % + glucose, 2 %; (b) 4-HPA, 0.1 % + glucose, 2 %. Pre-inoculum was prepared on PA (a) or 4-HPA (b). Growth profile on double carbon source is indicated by (●). Bar represents the rate of oxygen uptake on specific substrate, as indicated, in nmol per mg cells (wet wt.). Values are corrected for endogenous oxygen uptake. Reducing sugar concentration in the spent medium is represented by (▼).
