Madras Institute of Magnetobiology says electromagnetic field can boost algae growth

Various methods are being pursued to boost the growth of algae. One such specific and highly safe, natural approach uses extremely low frequency electro-magnetic fields.
This specific approach uses extremely low frequency magnetic fields on biological systems, resulting in these systems getting exposed to pulsed magnetic field (PMF). An alternating current surging forward and backward in a coil winding generates a magnetic field surging back and forth in the coil along its axis. Such a magnetic field is referred to as the PMF.
Biological systems interact with PMF, and these interactions can be largely grouped under:• Cellular and Tissue Interactions• Membrane properties and ELF signal transduction• Molecular Transport• Stress and survival• Repair and Regeneration
The use of PMF is common in agrobiology where dry seeds of crops, silkworm eggs, , various types of tubers and horticulture plant seeds are exposed to different parametric combinations of pulsed magnetic field for various responses such as enhancing germination, morphological, biochemical and yield aspects.
It has been suggested that microalgae can also be made to interact with a PMF for positive results.
Some of the research efforts made to analyze the effect of electromagnetic field on microalgae suggest that it is possible to enhance the nutrient assimilation of microalgae, thereby increasing the growth rate when placed under electromagnetic field.
Some related references for the positive effect of pulsed magnetic field on algae are given below1.

Pulsed Electromagnetic Field Therapy

Pulsed Electromagnetic Field Therapy is non-static, unlike therapy with magnets, which is static.Pulsed Electromagnetic Field Therapy is used in two main ways: Pulsed Electromagnetic Field Therapy (PEMF) or a special version of PEMF called repetitive transcranial magnetic stimulation(rTMS). PEMF therapy has been used to stimulate bone repair in non union and other fractures since the 1970s. This is an accepteduse, which has been approved bythe FDA. Although bone has a remarkable capacity to heal from injury, in some cases the brokenends do not join: these are called non-union fractures. PEMF has shown promise for other conditions as well. Now, many studies are showing its benefits in healing soft-tissue wounds; suppressing inflammatory responses at the cell membranelevel to alleviate pain, and increase range of motion. PEMF is now being investigated experimentally for osteoarthritis,stress incontinence, migraines,and many other conditions.
