It’s white if that’s what you mean.. but it’s not very uniform and doesn’t look to great to be honest.

Most people don’t let plates grow all the way to the edge because they usually get contaminated when they do.

Is this a spore plate? Did you take any transfers?

That's an interesting issue that you'll have to work around.

There seems to be some slight discoloration on the colony that's a 1 o'clock on the plate. I can't see enough detail to say if it's contam or not.

If you're going to take a section then perhaps take it from somewhere else on the plate.

Curious because I hear this advice often.  IME though it has never happened to me personally.  I have kept most plates just to watch, and based off this advice assumed they would show a contamination, but it has not occurred.  I have had germination plates literally go rhizo when they hit the edge and like ivy grow up the side and along the lid.

I’ve seen that as well on some of my neglected plates.
Personally I haven’t ever tried to spawn plates that touch the edge.
I’m just regurgitating what I’ve read. I have had pasty plates contam when it hits the edge tho.

Im not sure if you would ever see the contam?
... but that doesn’t mean it’s not there.

FWIW I have spawned multiple plates that touched the edge and 0 issue.  I've read exactly the same as you, but having not seen it play out in practice, I am questioning it. 

Should note I am talking strictly plastic petri dishes, not pastys or any other no pour. 

I agree that a contam does not need to be seen that could later cause issue.  But the unseen contam that never causes an issue is Schrödinger's contam.

I've even left plates unwrapped figuring they would have to go bad, and so far nothing.  Finally I took a test plate and mashed my finger into the agar just so I could see what would grow.  Whole lotta nothing fortunately or unfortunately.

That looks like tissue plates, the discoloration relating to the tissue itself perhaps.  It all looks good to me, i'd use any of that plate except for the swirly 12oclock, but thats just my personal OCD.

Hope all works out!

Now that I think about it condensation might have something todo with it?

Most of the no pour plates I’ve seen contam have lots of condensation.

I dont think it's a matter of the plate itself contaminating, I think its 2 things:

It's easier to see/transfer and distinguish myc types before they hit the edge, after they hit the edge they get intermingled

If contams were on the agar surface you'd be able to see it, but you cant see contams on the edge because there is no agar/food for them to grow on. These could be picked up by the myc and end up on your next plate/grain. even if the contams never germinate/bloom on the overgrown plate, they might once they hit food

It's more of a best practices for transfers/a2g/LC/LI thing than an "it will contam the plate if it hits the edge" thing. It's not that there are contams on the edge, it's that there could be and you wouldnt know until you put it to grain/transfer/etc

There is an app I saw someone use on Reddit where they changed the color somehow so they could see contams. I think it ended up having the sub look black, and contams looked some kind of blue. I may be wrong about the colors but check it out. Idk much about that stuff bud sorry

Side note and just an idea: have you considered adding food coloring to your agar?

Many do it and might be helpful to see contrast and growth of mycelium or mold.
And maybe over time be able distinguish by shapes and shades?

Looks okay.. definitely do more transfers before grain tho..

Contams only happen if contams are present.. I believe the main point of not letting myc hitting the edges is the culture loses vigor (definitely correct me if I'm wrong).. I've put many cultures to grain that hit the side without problems as well.. only a problem if you're trying to keep very vigorous growth in cultures in general

Awesome point, C10. I never thought about it this way, and this explanation requires no speculation. We can speculate on whether the edge is more likely to have a contam then the rest of the plate or whether the myc growth loses vigor, but in the end agar is used to KNOW if there is a contam or not, and you don't know if the edge has one. You could still pull the contam from the edge during agar removal to inoculate grain, but that seems less likely than having myc engulfing the edge of the dish pulling potential contams.

:awesketch:




No that's not it. It's the reasons I explained above. The idea of cultures "losing vigor" with too many transfers is greatly exaggerated , and the idea of losing vigor in the same plate is absurd

Think about it: myc expands probably 1000 times more in a grain jar than it does on an agar plate, and probably another 10 times more on a bulk sub. Does myc "lose vigor" when it hits grain? Ofc not.. the exact opposite usually. Is a clone culture less vigorous than it was on the agar its grain spawn came from? Ofc not. Maybe after 100 grows, but not in these short time frames for sure

A plate hitting the edge does not mean it WILL contam, only that there is a possibilty of picking up unseen contams (which you'd see if they were on the agar itself, kinda defeating one of the main advantages to using agar)

And you lose the visibility advantage for spotting different strain groupings and different types of myc once they intermingle at the edge.

For example:


Look closely at the red lines I drew. These separate 2 different types of myc growing on top of each other. If I transfer now, I can get the better looking one on it's own on the next plate, but if I let it grow to the edge that would be impossible since there would be no part of the plate where they had not mingled.

I know it's hard to see, but does that make sense?

That makes sense
I always thought about the slants and how little surface area there is and how it most likely be touching the sides after some time..
Definitely puts my mind at ease

Right, but you wouldnt be going from slant straight to grain, typically you'd grow it out on another plate first. Also, based on the way you use slants, you wouldn't need visibility to be looking for multiple types of myc growing over each other and trying to transfer one or the other (like you would on a plate)

So both of the reasons to transfer before it hits the edge dont really apply with slants
