Effects of a static magnetic field on phenol degradation effectiveness and Rhodococcus erythropolis growth and respiration in a fed-batch reactor

The aim of this study was to investigate a repeated short-term effect of static magnetic field (SMF) on the Rhodococcus erythropolis cells. The used SMF was shown to modulate the growth utilization of phenol and this modulation was found to be a function of both the exposure time to SMF and the flow rate of the exposed cell suspension. The maximum phenol oxidation achieved is around 34%, promoting an increase in R. erythropolis growth (28%) and respiration (10%) activity, what is accompanied with a shortening of lag- and exponential-phase interval.
