Plastic-Eating Mycelium : Mycelium that eats plastic * 2
    #29667427 -

I have read old articles about plasic eating mycelium. My question is: Is anybody on this forum currently culting plastic eating mushrooms. I am interested in your experience

Example:

Here is the genesis of my Plastic-Eating Mycelium Project.

Goal: To successfully cult a cult of plastic-eating mycelium.

Success = A cult of myc eating 100% of an unmodified water bottle

I welcome people to share their experiences with these cults

Yesterday I was on an high walk and thought about people trying to do some sort of transgene expression of plastic eating enzymes or whatever does this in different types of fungi. Finding a way to turn it into a waste management technique would be awesome

Very cool and thanks for sharing, definitely will need to do some more reading on this

I was thinking of something similar today at the gym. I was thinking about possible transgene expression of these plastic eating mycelium to start producing active compounds like psilocybin and psilosin. I definitely need to brush up on my research as well.

Thank you for your comment :thumbup:

It is very cool that certain mycelium can eat plastic. But don't even think that plastic eating mycelium will make a dent in the pollution problem. The solution would be for companies to stop making plastic and start making biodegradable non plastic containers asap, which they can do.

But I am loving the idea of somehow getting various mycelium to produce psilocybin and psilosin, as well as other drugs.

I like this idea as well.

I just made a Thread about it.

I also think in its current form, plastic eating mycelium is too weak to make a dent in plastic pollution. However, my project is to beef up the capabilities over generations to make it an actually viable option in the toolbelt of waste management (since thats literally what mushrooms are on earth for)

First off, thanks for starting this thread langten69!

On the point of current species that have been documented breaking down plastics:
- very weak and limited to the genus Pestalotiopsis, with several individual species showing this trait
- the genus is a "lower fungi" so it does not have a fruiting body/structure like we observe from the fungi discussed on this forum
- this particular genus has primarily shown the trait of breaking down #5 PPU plastics(think single use water bottles, but not the caps), but ineffective against most other varieties of conventional plastics

Now into the more interesting area, which I have never considered until now; "Transgenetic Expression" with the goal of producing measurable ratios of psychoactive akaloids to fruited mass:
- The genus Pestalotiopsis(only one I can find online) is a lower fungi, as mentioned above this does not fruit, so to extract akaloids you would need to use methods similar to the "myceliated grain extraction" I have stumbled on here on the shroomery.
- plastic is a hydrocarbon, all fungi break down hydrocarbons. The distallation and synthesis of hydrocarbons to produce plastic strengthens their bonds and in turn making them harder to decompose by the fungi. Following that line of reasoning less processed forms of fossil fuels should be easier to break down, this theory is backed by a study that Paul Stamets publicized a few years ago. If I remember correctly the study used a blue or gray oyster species that had been refined for many generations in a laboratory before being used in a real world study to restore an ecosystem after a crud oil spill.
- Many other species of mushrooms(and plants) produce psyhoactive akaloids, so maybe looking into a balance of traits for akaloid production and hydrocarbon consumption. Combined with a sufficient sized harvest and high efficiency extraction methods could be a viable theory to test.

I am looking forward to keeping up with this thread!

Please take this with a grain of salt, I am not a professional mycologist, if anything I have posted is incorrect I would love to be pointed in the right direction for more accurate information, and I'm just a nerd who likes to grow stuff!

How about a choice edible mushroom that breaks down plastics?

'King tuber' oyster mushroom, grown by tree frog.

tree frog said:
This oyster mushroom eats plastic.  Pictured is a king tuber stone, approximately 9 months since inoculation.

The metabolites are eating through a unicorn bag. 






Full thread of tree frog's grow. Apparently the bags started to leak metabolites after 6 months so they were placed in a tote.

Good points shroom_fae

And thank you CreonAntigone for sharing this example

I suppose the first thing to do is to create an exhaustive list of all mushrooms/fungi that have been documented to eat plastic...

Also, in answer to veggie, I think this could make a difference if you organized it and had companies that composted plastic in this way specifically. Let's suppose companies got a rebate to take plastic to a dedicated plastic composter.

It's work that is being done: take a look at this article. Biohm is developing fungi to do this. There's another company called Carbios that is using an enzyme derived from compost.

A texas startup sells a packet of Pestalotiopsis to put into the waste bin with your dispoable diaper.

These are cool companies. But I cant find any company that's really doing something to break down plastic load in the soil or water. I think that would be where the big environmental impact is.

I like the idea of organizing wastes of various types to apply specific waste breakdown methods to each one.

Thank you for sharing these articles

I suppose the main target would be: Identify the leading shareholder of plastic waste in water and soil and formulate its own specific waste management process

Yes! This is exact what we would want to start from, a variety that has an instrinsic value(tasty food) and can help the environment!

I believe this would fall in the "carbon capture credits" realm, which while deeply flawed every where it has been implemented, has some good intentions behind it.


On the diaper starup you mentioned: I am not here to disparage any organization trying to slow humanity's damage to our planet, but if you do a little more digging on that organization:
- the reviews are clustered in patterns consistent with "click farms"
- the first hand reporting is largely from paid content sources


While both of those indicators are weak, it does lead me personally to believe that product is mostly marketing hype. That and the cheapest option to get one of their cultures is $109, which seems very steep for a hobby that my most expensive purchase was a $50 microscope.

can you cite some sources?
I'm specifically interested in reishi and oysters, can you point me to information that suggests they degrade plastics?

also, why not include the king tuber oyster?  that one seems the most compelling to me.

Pleurotus ostreatus and Pleurotus pulmonarius

Pleurotus ostreatus

Trametes versicolor and Pleurotus sajor caju

Pterocarya phalloides, Reishi mushroom, Inkcap mushroom, and Pleurotus ostreatus

P. sanguineus, FBL, FV12

I had not come across literature that states king tubers eat plastic before your comment, however, the more that I read, the more eerily apparent it is that I feel most fungi have the capabilities to consume plastic when given the right circumstances

This article validates the polyethylene degradation of P. Tuber-regum as being superior to P. Pulmonarius.

Seperately we might guess its sclerotia-producing capacity might allow for more enzyme production when other Pleurotus are finished growing.
