The strongest mushrooms I have ate came from bacterial substrates. :shrug:

then again strong is subjective and it depends on the genetics you fruit.




That makes me wonder if their are beneficial bacterias to mycelium and mushrooms. Just like we need certain bacterias in our digestive system. Maybe its wrong to say every bacteria is a contam.



There are beneficial bacteria. It's the reason we pasteurize most bulk subs instead of sterilizing them. The problem isn't so much the bacteria themselves as the waste products and toxins they produce in large amounts while growing on highly nutritious spawn. Those same bacteria are harmless in smaller amounts.

As the mycelium colonizes the substrate it also changes which bacteria species are growing on the substrate. Some mushroom species can't even produce fruits without those bacteria.

I think it would make a lot of sense for the mushrooms to be weaker once the mycelium is compromised by a contam like trich. If the mycelium is attacked by trich, it chooses to shoot up as many shrooms as possible right away in order to spread spores quickly and enable the species to survive. I believe that in this rush, the mycelium forms mushrooms that are not as healthy as the normal mushrooms, which results in a loss of potency. This is all conjecture for now, but I think it's plausible.



Doesn't make sense at all if you really think about it. However if mushroom health and potency are linked then I would have to assume aborts must be very weak :wink:




Well that's a good point. If aborts are fine, then contam shrooms should also be fine. The problem would have to be mostly genetic.

Isn't agaricus bisporus a prime example of this? It seems to only fruit with pasteurized compost.

So I guess the consensus is it doesn't matter if it's contamed, the genetics will determine potency anyway :shrug:





It depends on what, when, and where the contam is. It could be beneficial, could be horrible. Some bacteria do somehow help with the digestion of the substrate. Genetics effect everything but we can not ignore the significance contams carry in a symbiotic relationship with cubensis and other species.

Perhaps P. cubensis generates peroxides when threatened and the newer mycelial strands are slowly damaged by the free-radical ozone ions bouncing around. If mutations and cellular damage occur rapidly enough if could have a compounding effect on the ability to fruit and reproduce due to mitosis of the damaged DNA. This is simply conjecture and i am not nearly familiar enough with the anatomy and cancer of fungi, its anyone's guess as to why they are weakened by certain contams. It's probably a combination of waste/toxins, nutrient depletion, damage from "fights", or maybe simple overcrowding and spatial problems of the multiple colonies competing over an enclosed container and meshing together.
