Biodegradation of Phenol and Sodium Salicylate by Pseudomonas putida BCRC 14365 in Batch and Packed-Bed Bioreactors: Model Development and Verification
AbstractKinetic biodegradation of single phenol and sodium salicylate (SA) by Pseudomonas putida Bioresource Collection and Research Center (BCRC) 14365 was studied at 30°C and pH 7.0. Experiments were conducted at different initial concentrations of phenol (0.33–3.86 mM) and SA (0.12–1.89 mM) in ba...

Based on the specific growth rate of cells versus initial concentration of single phenol and SA, phenol had a higher biodegradation rate than SA at a lower initial concentration (<0.7 mM) in the single-substrate batch tests. The magnitude of the Ks value indicates that the P. putida has a slightly stronger affinity to phenol in comparison with SA although the cell was induced with SA. The Ki value revealed that P. putida cells are less sensitive to SA inhibition (Ki=4.98 mM) than phenol (1.211 mM) at a higher substrate level. Experimental results for binary substrates in batch tests show that the addition of SA to phenol did not significantly affect the time required for complete biodegradation of phenol. However, the presence of a small amount of phenol could accelerate the complete biodegradation of SA.
