i still have some access to scientific studies.
And it seems that metabolism of the mushroom is somehow affected by aluminum.
The fruit apparently accumulates the aluminum.

The influence of Al3+ on the mineral content of mycorrhizal fungi was studied in vitro. Amanita muscaria (L. ex Fr.) Pers. ex Hooker whose growth is reduced and Lactarius piperatus (L. ex Fr.) S.F. Gray whose growth is stimulated by Al3+ where chosen for the experiments. 0, 0.1, 1, and 10mM A3+ were added as Al2(SO4)3 · 18H2O to modified M-40 medium. Al3+ drastically affected the mineral contents of the mycelia of both fungi:
the Al, Ca, and Na contents increased while P, Mg, and K decreased with the increasing Al3+ concentrations in the media.
On the other hand, some important differences between the two mycelia were detected. In the mycelia of Lacterius piperatus grown on the control media, there was about twice as much Ca content and a three times lower P content than in the Amanita muscaria mycelia. The Al3+ content in the mycelia of Lactarius piperatus grown on 10mM Al3+ was six times higher than in Amanita muscaria at the same concentration.

Notice the say the mycelia, and not the fruit bodies.  Anyways, my previous statement still stands.  Unless an accual person of science and health can chime in....verm oN!

there is another study on Springer where it states that the fruits grow bigger too.

Hi guys,
I stumbled across a post from RR  and it made my think if vermiculite might actually be harmful as a substrate. Since Mushroom prefer an acidic substrate according to RR and vermiculite contains aluminum could it be possible that the mycelium accumulates the aluminum? Aluminum leachings was found to be highest in acidic environments. Aluminum is a known neurotoxin that might cause alzheimers and other neurodegenerative diseases.
By eating the shrooms could we poison ourselves?

Quote:
Most mushrooms prefer an acidic substrate.  The problem is, so do molds.  We lime our casing layers(when used) to make them less hospitable to mold spore germination, while trying to find the upper limit of pH that mushroom mycelium will still thrive.

I wouldn't attempt to lower pH with sulfur or anything like that.  Simply use the manure, straw, coir, etc., as it is.
RR


vermiculite = Magnesium Aluminum Iron Silicate


How well can you digest a rock?

I think that the issue with plants and mushrooms storing heavy metals has more to do with them taking up organic compounds with some sort of a heavy metal in them or there being a lot of heavy metal ions dissolved the water that those organisms are taking up.  I honestly wouldn't worry too much.

How are you going to get dissolved aluminum out of a mineral that is insoluble in water?

Vermiculite dust is actually bad for the lungs, it behaves similarly to asbestos in the lungs. Lodges itself deep in lung dltissue, never goes away, causes irritation / inflammation, potentially mesothelioma.

Ugh. People get this all wrong. The aluminum connection to Alzheimer's has to do with a defect that allows aluminum to collect in the brain. Our bodies are bombarded with aluminum constantly. It is totally ubiquitous in our environment. Dirt, many types of rocks, and clay are all aluminum based materials. It is the third most prevalent element on earth. Our bodies normally have no problem processing and excreting aluminum. People consume up to a gram of aluminum everyday. It's not a heavy metal. It is one of the lightest elements.

A lot of water insoluble substances become soluble in acidic conditions.

Vermiculite is not going to dissolve because your growth medium is acidic...

It won't dissolve completely but aluminum ions will leech into water. Not much and it isn't going to be significant. People with healthy kidneys can consume upto 5g of aluminum a day without ill effects.

Apparently tea is one of the main sources of aluminum in a diet. Who knew?

Again, the fact that vermiculite is an aluminum compound shouldn't concern anyone. we grow all our food in soil, which is upto 10% aluminum by weight.

Don't go out to eat. lots of kitchens use aluminum stock pots and even frying pans. Most baking sheets are aluminum too.

Who cares? What are you going to eat and store you food in? Your plates and coffee mugs are also made of aluminum. Humans have been using clay pottery to store food since the beginning of time.

We evolved on a planet where aluminum is everywhere and unavoidable, and therefore we have evolved the ability to excrete aluminum from our bodies.

Aluminum doesn't cause Alzheimer's disease....

It also isn't a neuro-toxin...it only has effects at high doses and then it only affects the functioning of the blood-brain barrier.

Not in any way that you'd notice when testing the water chemistry.
