Summary
Rotating magnetic fields (RMF) can enhance fungal laccase activity and alter its properties. This study shows RMF offers a novel method for controlling enzyme-based bioprocessing.
Area of Science:
- Biochemistry
- Enzymology
- Biophysics
Background:
- Fungal laccase is a crucial enzyme in various industrial applications.
- Controlling enzyme activity and stability is vital for efficient bioprocessing.
Purpose of the Study:
- To investigate the impact of rotating magnetic field (RMF) exposure on fungal laccase catalytic properties.
- To determine if RMF can be utilized to modulate enzyme performance.
Main Methods:
- Fungal laccase samples were exposed to rotating magnetic fields at varying frequencies.
- Enzyme activity, optimal pH, and stability were measured post-exposure.
Main Results:
- RMF exposure led to significant increases in laccase activity (up to 11%) at specific frequencies (10 Hz, 40 Hz, 50 Hz).
- Broader pH range for activity and a shift in optimum pH from 4.0 to 4.5 were observed.
- Enzyme activity, stability, and optimum pH were demonstrably altered by RMF characteristics.
Conclusions:

A moving charge or a current creates a magnetic field in the surrounding space, in addition to its electric field. The magnetic field exerts a force on any other moving charge or current that is present in the field. Like an electric field, the magnetic field is also a vector field. At any position, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle points.

5.8K
A solenoid is a conducting wire coated with an insulating material, wound tightly in the form of a helical coil. The magnetic field due to a solenoid is the vector sum of the magnetic fields due to its individual turns. Therefore, for an ideal solenoid, the magnetic field within the solenoid is directly proportional to the number of turns per unit length and the current. Conversely, the magnetic field outside the solenoid is zero.

The representation of magnetic fields by magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. Each of the magnetic field lines forms a closed loop. The field lines emerge from the north pole (N), loop around to the south pole (S), and continue through the bar magnet back to the north pole.
Magnetic field lines follow several hard-and-fast rules:

01:24Energy In A Magnetic Field
2.7K
If a magnetic field is sustained, there must be a current in a closed circuit or loop, implying some energy has been spent in creating the field. If this energy is not dissipated via the circuit's resistance, it is stored in the field.
Take an ideal inductor with zero resistance. Although it's practically impossible, assume that the coil's resistance is so small that it is practically negligible. The loss of the field's energy to dissipate thermal energy (or heat) is thus...

The definition of electric field lines greatly eases the visualization of electric fields, a vector field, especially in the presence of many charges. The one-to-one correspondence between the electric field and the electric field lines necessitates that the field lines follow some rules.
For one, the electric field of a positive charge must originate from it. That is because its electric field points away from it. Moreover, since the magnitude of the field asymptotes to zero at infinity, the...
