Help me ID this possible contam
    #14332339 - 04/22/11 11:04 AM (10 years, 22 days ago)

So a few days ago, we might have 2 kinds of contam. please help ID. Using PF Tek, TCs and Cambos.

First one could just be blue bruising on cake. There is some mush growing, should I chuck it and not take the risk? Cake was immediately removed.





Second type is like lime green thin layer and is on the perlite. Tough to see in pic. Scooped out offending perlite and hope it doesnt come back.





Any advice?

Mushrooms are ok.
You can get better pics- with any camera- by using sunlight.
The blue cake, I'd recommend dunking.
Green on your perlite might just possibly maybe be algae, which is harmless.
More likely, it's nothing at all, which is even more harmless.

Either way, wash your perlite. Maybe boil it if you're in a mood to.

I'm working with what I've got, but the first one pic appears unhealthy. Are those pins sprouting from the bottom of the cake? The way they are broken indicates contamination & bad humidity...but of course a better picture would rule out any uncertainties.

The second pic definitely has some green mold in the center of it, chuck it before it gets worse.

In the third pic--is that grey color in the perlite just wet/damp perlite? If not it looks like cobweb mold.

As for the fourth picture and your comments, if there is a thin green layer of slime on your perlite, I would completely abandon your terrarium.
How are you regulating humidity, just with wet perlite?
In my experience, shotgun terrariums w/perlite acted as harbingers for molds. I had mold in my perlite within the first week of putting my cakes in.
Though I used sterile technique, there are just too many dust particles and mold spores flying around my central air system. I usually put my half-pint cakes in quart sized jars, individually; they regulate humidity independently in the small space. I also put them in an enclosed area, far from any exhausts of my AC.

Good luck.

(Harbinger isn't the word you want there, though it's a great word.)

I completely disagree with everything you're saying about shotguns, perlite and mold.
And that's what makes the internet great!

Thanks all

More info - dark spots on perlite is just vermiculite that came off some of the cakes.

Humidity is not regulated. Terrarium is big tupperware with 2.5 inches of perlite on the bottom, damp. There are 2 large holes in terrarium for new air.

Green perlite - this is like a tiny thin layer of really LIME green in a few spots. I picked it off, and hasnt been back for 36 hours.

Maybe I will wash the perlite, good idea.

Tiny mushrooms on cake with blue spot - I guess Ill chuck em, they dont look healthy anyways - is it TOO humid? is that why they look wierd?

And I always get pins outta the bottom of the cake. Stupid Shrooms...

Thanks all
