Good news!? Temp & bacteria...
    #595696 - 04/01/02 06:14 PM (14 years, 8 months ago)

I had a plastic ziplock bag of one pint of crumbled birdseed that had that nauseating sour apple bacteria smell. Figuring it was hopeless, I was going to just toss it. But as an experiment, I left it in a box on the patio. I live in California, where the nighttime temps get down to about 50-60 degrees F and about 65-75 during the day.

I checked the baggie about a week later and lo and behold: it was full of white, fluffy mycelium, instead of the stunted mycelium previously noted. More importantly, there was no telltale bacterial odor.

I am wondering if drastically lowering the temperature for an extended period of time on bacteria-infested substrate gives the mycelium an advantage and allows it to grow faster than the bacteria. (I would think the refrigerator would be too cold and would slow growth too much.)

If this is true, it could help save a lot of failed jars.

It sounds like something worth trying.. here in Montana we have strange weather, it was 70 to days ago and it snowed 6 inches yesterday.. I'm going to stick my infected jars near my window where its cool and see what happens. Thanx for the info, it will be interesting to see if this works and it sounds like something we need to experiment with because many of us newbies have contam problems and this would be a great way to save contaminated jars. I'll be sure and post the results.

Was there any change in air exchange potential when you placed the bag outside?

Both inside and outside the substrate (compost + bird seed) was sealed in a large (1 gallon), non-breathable ziplock bag.

When inside, I may have opened the bag on occasion to check / smell. While outside, it was left undisturbed for at least a week.

Looks like it may start pinning soon. It's a miracle!

Just replying again now that I have some results.. I had some cobweb bacteria on my incubating cakes awhile ago, I turned off the heat in the incubator and let them sit on the cold floor near my window.. the mycelia has slowly overtaken the cobweb and now the cakes appear to be bright white and nearly fully colonized. It seems that these mushies are a strong bunch and if you give them the advantage they can beat out almost any contam.... cold doesn't hurt the mushies but the contams can only live peacefully on the beach drinking Mai Tais. Thanx for this post, I think it saved my cakes that appeared contaminated and I wouldn't have thought to chill them a bit if I hadn't read this. I'll try and post more info after the cakes are birthed.
(note, when I say "I" I really mean "my neighbors dog Sam")

cut em open. A lot of the time it seems the mycelium has won but the inside is completely fucked.

I think, if the bacteria some how hybridized with the mycelium and it continued to grow, you be pretty fucked if you ate the shrooms off of it.. but then of course it might end up being a super strain or something... who knows.  I wouldn't suggest eating the fruits off of that mycelium, or even growing them for that matter... but do as you will.

To bad we don't have a resident chemist we could send this shit to for analysis! :smile:

Any volunteers??? :smile:
