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

Popis výsledku v původním jazyce

The aim of this study was to evaluate the impact of short-term repeated exposure to a static magnetic field (induction 370. mT) on the Rhodococcus erythropolis cells. Specifically, it was ascertained the magnetic field's potential to influence degradation of a phenol substrate, cell growth and respiration activity (oxygen consumption) during substrate biodegradation. The experiment took place over 3. days, with R. erythropolis exposed to the magnetic field for the first day. During the experiment, different recirculation rates between the reactor and the magnetic contactor has been tested. Use of the magnetic field at higher recirculation rates (residence time in contactor was less than 7. min) stimulated substrate (phenol) oxidation by around 34%; which, in turn, promoted R. erythropolis growth by around 28% by shortening the lag- and exponential-phases and increasing bacterial respiration activity by around 10%.
