Knots in my L.c.

I'm getting what looks like knots and little pinheads in a liquid culture that's a week old clone off a plate on witch little pins were growing off a tissue sample.This plate has been sitting around since 2014.I decided to give myco engineering another go.So these knots are they aggressive mycelium or bacteria ? I have knocked a few jars @ Day three with nada growth.The first pic is the myc. at rest on the bottom.The second pic is spinning in the jar.

Bin it unless you started with clean agar.

Then by all means I better trash it, although I explained in the post that it is cloned tissue. Your advise would be a bit more valuable if you read the post first.

If you can work with agar you should just put a drop on another plate. If it's bacterial it will be pretty obvious.
I've had bacteria show noticeable growth after 18 hours on agar.

I'm just wondering if any one else has seen this phenomenon (knots and pins ) in a L.c..I'll know if it's contaminated soon enuough.

I've had similar stuff before. Usually from myc forming around small bits of sediment.
Hard to say if that's what's going on though.

I must've misread, because I could have sworn it just said your pins were growing off the tissue sample grown in the LC. Don't think that's happening, but I digress.
Perhaps add a little more detail in there because from what I read, I got that you didn't use agar at all.
AT ANY RATE, all this is really pointless, because at the end of the post, I did say bin it unless you started off with clean agar. If you did, that's great. Grow away. If it wasn't clean, again, your LC is trash.

It started on a 2 plus year old plate!I removed a couple pins that grew on the plate and tossed them in L.c.

I understand now bub. I did misread, apologies. Small phones suck. I've never encounter pins in an LC ever however. If you're confident it's clean, knock a jar with it and see what it does. That's the thing about LCs. You never really can tell until you test it.

I will say this though. If you had this on a plate for two years, and not a slant, even refrigerated, bacteria can proliferate. This is why people store their cultures in slants for years, and not plates.

Why does a plate contaminate but not a slant? I thought the only reason for slants was they take much longer to dry out.

Because plates usually already have bacteria on them to some degree or another. When slants are started, you generally do them with super clean cultures and the surface area is so small, the culture doesn't give bacteria a chance to get on the agar.
And yes, they do take much longer to dry out.

Recently mushrooms have lured me back. I live on a 100 acres and I want to learn how to remediate contaminated soils as a business.So while I am waiting for my cubes to arrive for honing my skills I found this old plate that still looked OK for it's age, and I thought why not try to revive it.

I won't use a plate for anything if its been colonized for more than a week or two....
I doubt a plate from 2014 would be viable....I suspect all you are seeing in that jar is bacteria. If anything you should drop a piece of the old agar on fresh plate and use new growth as soon as you see enough to transfer to the LC
Can i ask how the plate was stored? Do you have a pic?

Yeah I hear ya. I just say make up a test jar a knock it up. See what it does. If it goes bacterial, it goes bacterial.

Yeah or make an agar plate if you have the means (and everyone has the means)....better IMO to waste agar than grains.

Plate was stored on a shelf , sealed with tape . At the center of the plate there was a blob of pins witch I removed, dropped in L.c.and then hit with the blender.No pics taken.
