Abstract: A polypropylene (PP) hollow fiber membrane contactor was used as a reactor to enhance the biodegradation of equimolar phenol and sodium salicylate (SA) by Pseudomonas putida CCRC 14365 at 30 degrees C and pH 7. Experiments were performed at a fixed initial cell density of 0.025 g/L and in the total substrate level range 5.32-63.8 mM. The degradation experiments by free cells were also studied for comparison. With pristine hydrophobic fibers, the degradation of SA was started only after phenol was completely co…
