University of Western researchers quadruple algae growth using low-level magnetic fields. A solution for biofuels?

My Clean Break column today revisits the importance of producing biofuels from algae, especially in the case of producing renewable fuels for the airline industry, which can’t electrify its fleet like we can with cars and trucks. But I also zoom in on some research conducted at the University of Western Ontario, led by biochemistry professor Wankei Wan.

Wan and his team created a tabletop algae pond in their lab — in this case, a raceway pond design — and monitored the growth of a type of algae called Chlorella kessleri under certain light and temperature conditions. They then replicated the setup, only this time they circulated the algae in the pond through an area that was exposed to low-level static magnetic fields. An electromagnet was used in this experiment, though Wan says they could have also used a permanent magnet no stronger than a typical fridge magnet.

So what did they observe? Seems algae thrive under a certain level and length of exposure to magnetic fields. Wan’s team, in fact, found a level of optimum exposure that led to a quadrupling of growth of the biomass, the oil inside the algae and in-cell antioxidants, such as Astaxanthin. Wan believes the approach could be used to help boost algae production for both biofuel production and the production of food supplements based on the antioxidant nutrients found in algae.

Actually, while this is a potential benefit for biofuels, Wan sees a much larger opportunity to use magnetism to boost growth for the production of high-value products — i.e. chemicals and nutrients (such as Astaxanthin) that can fetch much more in the market than biofuels. His research is expected to appear later this year in the peer-reviewed journal Bioelectromagnetics.

Wan isn’t the first to observe this phenomenon. Researchers have been exploring the effects of both magnetism and low-level frequencies on simple-cell organisms such as algae and bacteria for a few years now, and in most cases they have observed growth stimulation. This study provides a good overview of that earlier research.

  1. Nice pick up! It would be great to connect these people with Dan Winter of http://www.FractalField.com who manufactures the Imploder http://www.theImploder.com which can boost agricultural production and life force in all life – the chi key! Dan’s main site is http://www.GoldenMean.info and if future science interests readers go to http://www.RedIceCreations.com to listen to yesterday’s interview with Maurice Cotterell about magnetism, electricity and gravity.

  2. The magnetic connection to algae production: Could it be used to separate one type of algae from another? Could it be used to concentrate the algae during the harvesting phase? If they have found the “sweet spot” field strength, there are all sorts of directions their research can follow.
