lol yea, i hear that man.  truth be told, even g2g can fail us like that.
agar plates are key.  assuming technique is on point, the OG plate will always tell the whole story in those cases.

Man I went for like a year and a half not able to grow a fucking thing past first flush, and only 50% of what I tried even made it that far.


But I'll be goddamned if I'm not an expert on contamination now though. Keep at it and learn as you go.

:bump: and a quick update. This contam.. I've been keeping it around out of laziness really. Too lazy to throw it out :lol:

Quote:

This is a random white contamination I got I wanted to share, showing how similar some white molds can be. This right here is why you NEED to be thorough. The contamination is circled.



This is another one, except the circled in part is healthy mycelium:



Since these were transfers that went wrong, I know for a fact everything outside of the spots I transfered to are contaminations (also I've been keeping a close eye on them since I noticed the white growths).




Well here they are now! Exactly 3 weeks later!

First one:

Notice how much the growth has grown out.. :thumbdown:

Second one:

The clean growth is black, but what's interesting is the mycelium colonized through the stuff highlighted in red. HOWEVER. The white growths and shit in the red shows how unorganized it is. This is something you SHOULD NEVER trust. Mycelium colonizing contams doesn't mean it vanquished it. The contamination is still there, and it's still dormant.

It's also interesting to note.. they both smelled extremely mushroomy.. If I was to use my nose, I'd think they were clean. Even though I know they're not. This is why I really don't like advising people to sniff shit (unless your spawning or birthing, then sniffing every jar is recommended :thumbup:). Your eyes are 10x better at spotting crap during colonization though.

If you get sleeves of petris, they're pre-sterilized.






I know this is a somewhat old thread but i was wondering if its okay to only use half of the petris in the sleeve. I know they come with some type of gas in it that keeps it sterile but once i open the sleeve is it okay to use half and then reuse them later?

There's no sterilizing gas. They're sterilized with radiation. You just have to keep them sterile by closing off the sleeve they're before you take them out of the SAB/FH.

Anyone got more pics of hidden/meshed molds?

Ever since I suspected a few plates of having them every piece of mycelium seems suspect now.

This thread is a goldmine by the way, shame it is not full of pics. Hopefully I won't have resurrected an old thread for nothing :P.

I wish. I haven't seen many with infused molds. Really just the one from madd is about all I've seen.

Too bad. Been noticing some suspect mycelium in some of my cultures. Not knowing for sure is a nuisance, guess I will have to test them out by fruiting one by one.

Make sure they're uniform and organized. It can take many, many transfers sometimes. If they're not organized and uniform, they're not clean in my books. I've never had a culture I couldn't clean up. Even plates covered in bacteria before any cube germination I've saved with just transfers (no antibacterial agents used). I've seen lots tell others it is garbage when it's pure bacteria, but it isn't the case if you enjoy cleaning cultures lol. You get a huge sense of fulfillment when it works :smile:

That's the problem though, they look organised but strange, like having trouble growing over the agar surface or going from rhizo to wispy after a xfer when the recipe is the same.

I'm stuck changing my decision every 15 mins I spend staring down at them. :rofl:

Like the one below. Some parts it's organised and beautiful yet all around it is all this strange growth. Strange thing is, the sector I took that transfer from was totally rhizo with no cottony growth at all.



There are others which I took transfers from nice rhizomorphic growth but they have a hard time staying above the surface and growth is all strange.



I tried to take clear pics of the growth under the surface the other day, this is the best I could come up with.

Would you say this culture has a slight hidden bacterial issue, Mad? It was grown out with slow pin formation, and results weren't anything to write home about.

Looks off. Theres a lot of "aerial" growths. I would try to transfer until it is smooth.

So you're concerned because it grows under the surface? Like to the bottom of the dish under the agar? If you use food colouring, you'll see the myc break it down.


The first has many sectors because it still has lots of genetics in it. Keep transferring from the leading edge until you get to it looking like this:



If you're talking about the thin film around it, that is just mycelium.

The last 3 pics, the first 2 need to grow out more before making much of a call on it, but so far they look alright to me, the last one has leading edges perfect for transfers. It can take lots of transfers before they look uniform and organized.

Yeah, the stuff under the surface is what I meant.

I have never really looked at them with this much detail before so that's why I'm not entirely sure about it but it does seem awfully suspicious to me. I have never seen mycelium do this before. I know mycelium does colonize agar completely but never really done so like this before.

Guess I will know for sure once I try and fruit some of these.

Sometimes that just happens, especially when transferring to a different agar mix. Keep transferring until you get a monoculture though. It's the best way to help ensure it's pure.

Does mycelium climbing the walls of a colonized plate definitely mean it's bacterial, or could it be because some of the agar liquid is actually on the sides of the plate (or in my case glad mini rounds)?
