Biotechnology Letters Aims and scope Submit manuscript

Summary

Phenol degradation by free and immobilized cells ofFusarium flocciferum was studied in a chemostat at steady-state conditions. For the free cell system the dilution rates varied from 0.02 to 0.13h−1, with a total phenol removal up to 0.08h−1. Wash-out seemed to set in at 0.11h−1. The immobilized cells showed virtually complete phenol utilization at 1g/l, over a period of four months. At D=0.2h−1 and above 1g/l phenol, the complete phenol removal is not achieved: a progressive increase in the outlet concentration was observed attaining a value of 284mg/l at 1.5g/l.
