phenol biodegradation in a bioelectrochemical system

In this study, a single chamber microbial electrolysis cell (mec) was designed and constructed to investigate the phenol (200mg/l) biodegradation as the sole substrate using ralstonia eutropha# in anaerobic condition of the system, the biodegradation rate of 2#6 g/l#h was obtained at an applied voltage (vapp) of 0#5 v# then, we also explored the effect of applied voltage (vapp) on phenol removal rate # in this regard, phenol (100 mg/l) removal at two differnet applied voltages of 0#5 and 0#8 v was investigated# the system had more efficient performance in term of phenol removal in vapp=0#8 v, and phenol degradation rate was calculated 3#9 and 5 mg/l#h, respectively#
