And the microbial energy was

MICROBIOLOGY ■
Electricity produced
by certain bacteria
could become
a new source
alternative energy.
Applications
are still limited,
but the results
are promising.

In the same style I had read an article on the quant'homme site and intersected the track on the science and life site.
An English botannist discovered bacteria which produce electricity by consuming sugar and the discovery dates back to 1902 I believe.
Yupi, another track : Shock:

Bonjour.

Too bad the source of info on this subject is so rare.

Given the recent epidemics, I think bacteria can be scary. Not to mention that to increase performance the temptation to resort to GMO bacteria can be strong, therefore possible slippages.

Recent epidemics are viral (chikungunya, avian flu) and not bacterial. As for bacteria, they have been manipulated for a while to produce particular molecules. It's biotechnology.

Currently researchers are working on viruses, and in particular bacteriophages which kill bacteria for therapeutic purposes ...

So using bacteria for energy production is not only conceivable but may be the future.

In sediments there are a lot of biocenoses composed of bacterial communities with cooperation where one of the strains degrades compounds to produce others which are used by another strain and so on.

It is not impossible in the future to have such communities made up of bacteria degrading waste and others adsorbed on supports in order to deliver electricity. Or communities made up of microalgae with electrobacteria instead of photovoltaic panels ...

Bonjour.

I agree with you, the recent epidemics are due to viruses and not bacteria. But the "general public" hardly distinguishes between bacteria and viruses.

Some specialists / doctors are also worried about the fact that we weaken our naurelle defense (and that of farm animals) by overuse of antibiotics and it seems (let us say) that microorganisms (viruses, or bacteria, this time I know more) become more and more resistant to what we use to fight them.

I am not a very advanced culture on the subject, but it seems that microorganisms have capacities of adaptation and genetic mutation far superior to ours. I wonder what means of "control" do we have.

It also seems to me that a lot of applications, including this one, (and some of soil remediation) are very interesting. But when microorganisms are released into the wild, there is no "emergency stop" on it.

If you know or find information on the subject, I am interested, thank you.

Hello,

To this question, I can answer, antibiotics are only effective against bacteria, no effect on viruses.

Somewhere, the fact that the adaptation of a species having a latency between generations of the order of a second (bacteria) is greater than that of a species needing twenty years to see arriving a new generation (the human) is relatively explainable.


If not, to return to the general subject of the post, our scientists will soon find the solution to our problems of waste and pollution due to incinerators: new factories or bacteria will eat our garbage cans to make electricity.

After "no arms, no chocolate", here comes the time for "no waste, no electricity" : Cheesy:
