Researchers Show 17% Boost in Ethanol Production with ELF Magnetic Fields

Researchers in Brazil have successfully used extremely low frequency (ELF) magnetic fields to significantly boost the amount of ethanol produced through the fermentation of sugar. Their study is scheduled for the 5 October issue of Biotechnology Progress, a bi-monthly journal published by the American Chemical Society.

Victor Perez of the State University of Campinas, Brazil, and his colleagues showed that yeast-based fermentation of sugar cane in the presence of ELF magnetic fields boosted ethanol production by 17%. The scientists also showed that ethanol production was faster, taking two hours less than standard fermentation methods.

The results presented in this report suggest that an extremely low frequency magnetic field induces alterations in ethanol production by S. cervisiae and that the magnetic field treatment can be easily implemented at an industrial scale.

The cellular suspension from the fermentor was externally recycled through a stainless steel tube inserted in two magnetic field generators which were operated conveniently in simple or combined ways. The recycle velocity and intensity of the magnetic field varied in a range of 0.6-1.4 m s-1 and 5-20 mT, respectively.

The best results of a 17% boosts in production were achieved under the conditions of 0.9-1.2 m s-1 and 20 mT plus solenoid.

In discussing the results, the researchers concluded that:

...we postulated that the positive effect on the ethanol production under magnetic field is due to both membrane permeability and a redox system that are affected by the electromagnetic field, resulting in alterations of ion transport (substrates) and consequently resulting in stimulatory effects on cell metabolism.

I am extremely skeptical of this.

What would be the total potential production gain if all recent improved methods were combined into the same plant?

tripp

Well, it shouldn't be too hard to confirm or deny it.

More like explanation is that the Researchers were drinking the Ethanol.

Ben

Aha, if this really works I would like to see a better theory on is mechanism of action. Yes 3rd party testing on this is very necessary, its claims are high and its explanation is very vague, common signs of a scam. Also how much energy is wasted by the ELF device?

Exposing cells to electrical and magnetic fields is a well established technique to increase cell membrane permeability. See http://en.wikipedia.org/wiki/Electroporation

People think tomatoes grow better to music when in reality they are optimising other conditions. Same here maybe.

Ben

Electroporation uses electric fields not magnetic.

Electric fields cause magnetic fields. That's why if you send a current through a wire wound around a nail, the nail becomes a magnet. This is extremely possible and I am fascinated by this discovery. I imagine that this technology would have even been impressed Nikola Tesla.

How much extra energy does this process use? If it's equal to or more than what it produces then it's pretty much useless I'd think.

Ben

A electomagnet is not a magnet. Direct electric fields are able to move charged ions through cell membranes, you might get away with the same trick by moving an ionic solution of cells though a magnet (electromagnetic induction), but it would be easier just to run a current through them. In any case the how and why such a thing works (if it works at all) needs to be studied before practical uses can made controllable and predictable (and thus practical).

Frankly, why should we even care how efficient an ethanol process is. Since the raw efficiency of photosynthesis is so crappy to begin with.

The real bottleneck is that they are using plants to capture energy, and they do a really bad job at it.

Wups.

Aside for the dreams (or nightmares) of synthetic biology you can't make PV power into plastics and industrial solvent can you? So there is a use for biomass if not for fuel then for replacing industrial oil.

Aaron

GreyFlcn, photosynthesis itself is nearly 100% efficient. It's one of the most efficient energy conversion systems in existence.

Now, the ethanol made from plants...that's a whole other issue.
