Main outcome of study (acc. to author)

The maximum and minimum enzyme activities of cellulase occurred at magnetic fields of 2.2 mT and 4.2 mT respectively after 20 minutes.
The authors conclude that treating the enzyme/substrate solutions with different magnetic fields could inhibit or facilitate the enzyme activity.
