* Cells grown on various carbon source (PA, 4-HPA or Glucose) are monitored for
their O2 uptake rates on these substrates (see Materials and Methods for detail).
Abbreviations: PA, Phenylacetic acid; 4-HPA, 4-hydroxyphenylacetic acid; 3,4-
DHPA, 3,4-dihydroxyphenylacetic acid; 2,5-DHPA, 2,5-dihydroxyphenylacetic acid;
3,4-DHBA, 3,4-dihydroxybenzoic acid. Rates are corrected for endogenous oxygen
uptake. Cells were grown until the late log-phase. tr, O2 uptake less than 0.5 nmol
min-1 mg-1 cells. Values after ± indicate SD observed.
