Full recovery of stalled oyster mycelium!
    #19103954 - 11/08/13 03:39 AM (10 years, 2 months ago)

I did a little experiment in taking some Oyster plugs that got dried out for a few months and tried to colonize a few quart jars of supplemented sawdust with them. The mycelium was real lightly fuzzy and kinda stalled out after colonizing the entire substrate... It was not thickening at all even after sitting a week and a half fully colonized.

So... I had the fine idea of taking a couple pieces of wood extracted out of a wild log with a wild strain in them and tossing them in the jars on top of the stalled mycelium.

After only a few days there has been a stunning change in the jars with the colonized wild strain placed in them. The mycelium across the tops of both of the jars changed from fluffy and weak to strong thick looking stuff that looks more like the pure wild strain mycelium.

It kinda appears like the commercial strain is getting infused with the genetics of the wild strain or something. Pretty crazy! The one jar that wasn't modified is still sitting there stalled. About to put a sample of the wild strain in there to recover the jar.

I wonder what I will end up with... This is very interesting! I figured the strains would be compatible as the commercial one was originally collected in Washington.

Interesting. I'd be curious to see updates on this experiment. perhaps the wild strain is outcompeting/overtaking the commercial? Or maybe they are sharing genetics as you said. Seeing as blue oysters are the same species (but a different var.) of p. ostreatus, perhaps blue oysters and pearls could share genes ans show a similar increase in vigor? sounds like its worth an experiment. Anyone ever done this sort of thing?

I don't think they are competing. Both are pearl strains. One from here, one from Washington one state north. The mycelium seamlessly connected. Also, the recovery/behavior change of the mycelium across the entire jar occurred across the entire area.

I am going to place another sample in the last stalled jar and see if it recovers the same too.

Oyster mycelium is amazingly resistant. Ive seen a clone get totally contaminated with cobweb and then watched for entertainment purposes the mycelium recover and grow over the cobweb. Few mushroom species can do that!
