using electricity to kill trichoderma?
    #19364391 - 01/03/14 05:04 PM (10 years, 1 month ago)

I read that someone had contaminated mushroom mycelium, dunked it into water and applied 12 volts of electricity which killed the trichoderma, but the mycelium was fine? What does everyone think of this? I mean I'm a newb...but I already hate the green stuff, seriously.

I'm not sure if something like that would work. It seems that if the electricity can harm the trichoderma mycelium it would also harm the mushroom mycelium. Unless the trichoderma colony was small enough that it couldn't recover and the mushroom was big enough that it could. Its possible but unlikely. I have thought that it may be possible to kill bacteria with electricity without harming mushroom mycelium if carefully administered. But that would be difficult.

Current won't flow just by applying 12V to water. There needs to be an electrolyte in the water.

If using tap water there would be enough dissolved minerals in it to allow some current to flow.

True, but at only 12V the electrodes would probably have to be really close together. The amount of current the battery could supply is another factor.

Here's a funny video that's kind of related to the topic.

well I seen this on 'another' forum. I am not part of it, but it popped up in a search. is it ok if I send you the link RR, and you can tell us what you think? nm...the post was from 2010...and I guess if it actually worked, folks would of made it solid by now surely...just a waste of time I guess.

Yes link it here. The community as a whole can critique it. I mean it might work, but then again it might not. There's a number of variables. Honestly it seems like you may end up spreading spores by messing with a contaminated project. But lets see what the person did.

Makes me giggle when I hear stuff like this.

And why would everyone need to critique it? RR is an electrical engineer, doesn't his qualification speak for itself?

There are, for some reason, people who think that a little electricity will solve everything.  They're the same people who believe in adding hydrogen generators to their cars or adding acetone to their gasoline.  They have good intentions, but lack understanding.  They believe that faith is science.

My own father is one of those people, I love him to death, but he makes his own science.

That guy shows considerable disregard for sterile procedure from what I gather from the photos. Which is likely why he was suffering from contaminants in the first place. That being said he claims to have been successful and showed clean white mycelium after being treated by electrolysis. Although an interesting concept, I would say even if it does work its more prudent to throw something like that out. It is best to not risk opening a plate contaminated like that because you will be spreading spores everywhere and further propagating your contamination issue.

Also I find it odd that psilocybe mycelium is magically immune from the electrolysis while it killed trichoderma dead. There was no way to isolate the two, so they would both be getting shocked. Perhaps there could be some byproduct produced during electrolysis that is toxic to trich but not psilocybe.

Come to think of it, given fungi's tendency to pick up metals I wouldn't be doing electrolysis anywhere near mycelium. Electrolysis will slowly eat away at the electrodes and what ever metal is being used will end up being suspended in the water. I'm not sure if that would actually be an issue but it would be prudent to avoid doing this IMO.
