What mould is this? Enmeshed?
#27702216 - 03/20/22 08:28 AM (1 year, 10 months ago) |

My plates started out fine from spores and with each transfer they got worse and worse with this mould. I've seen posts talk about "enmeshed" mould I'm assuming that means its always present within the mycelium so transferring away from it will be impossible.




I can't seem to get away from it. Sometimes its just a halo around the mycelium which then grows over it so you barely can see it. These transfers were the worst yet.
Any help?

I’m pretty new but I had plates like that, it wasn’t “mould” as far as I could tell.
It was an issue with my agar recipe.

This must be some sort of mould its not allowing the mycelium to grow in certain areas, and others its just completely taken over.

That first pic you might be able to get a transfer, the rest look bad.
Its probably best to start off again from spores on a print imho. You could be at that for months transferring.
Otherwise mybe use a brf verm cake and transfer to that, hoping the myc outruns the bacteria. or search josex poke.

The problem is its underneath the mycelium, so transferring just transfers the mould with it. These were fine from spores to start off no signs of mould them slowly got worse.

Yeah, spent way too much time trying to clean stuff like that up on agar and not knowing better.
Had to go back to a spore print and eventually after like half a dozen times of trying, eventually got some clean myc. Dirty spore prints can be like that.
Mybe someone else will chime in with better ideas.
There is anti bacterial agar and chemicals you can try if its important to keep.
I've tried doing a hot pour, adding another layer of agar on top in the hope that the myc will grow up to the top layer a few hours before the bacteria. Didn't work out for me though.
You could mess about with the agar recipe, low nute content to encourage vigourous myc growth and do a firm agar. Frustrating but you'll get some clean myc one way or another, mybe try a new print.
Edit: Not 100% sterile scalpel or inoculation loop can do this too

If it's just getting worse with every transfer, it's not likely to randomly start getting better. Start a new spore plate and make sure your initial transfers are from clean colonies. Streak your spores to the plate so you can easily distinguish the different colonies.

They started out looking very clean. Then some began to have the halo around them and growth would slow. So how do I know what's clean and what's not at the beginning? Very hard to see by eye until it gets to this stage

Is it just this culture??
I had a very similar issue that was caused by my plates. Something was off with a batch of agar and every culture grew slow and thin like that. As soon as I moved them to new plates with good agar they were fine.

I just hold them up to a strong light source and look at them from both sides. Look for fast growing mycelium that's along the streaks and take a transfer from the very leading edge of growth in a clean part of the plate. If you blast MS on a plate and let growth completely cover the surface, it makes reliably selecting a clean initial transfer more difficult.
Agar recipe *can* alter the growth of mycelium, but it's generally consistent to all growth on the plate from my experiences. What recipe and % was used?

No actually I'm running 4 at the moment and all have been this very weak whispy mycelium. Lots of slow growth they all seem to have the "halo" thing. All have been really thin mycelium up until T3 where I've seen rhizo growth towards the edge of the plate. Now on T4 and they look like this. A transfer from another culture on these new green plates however looked really strong and thick but got contaminated so did a quick transfer of that today so I'll see how they go.
I buy my plates premade as I don't really have the means to do it myself right now as I'm living with family. Would love to try and do it myself eventually because its getting expensive and before I know it I'm out of plates and have nowhere near the strong/clean growth I want so need to buy more

Here's how it started:
Swabs to plate looked strong to start and grew super quick and really thick.


Then after taking transfers and letting grow out they looked like this:



Then I started seeing some rhizo strands so i transfered those


then plates started looking like this:



now this new batch of plates I got I got the really weird looking mould slime stuff but one of my cultures was like this looked really thick and strong but got contaminated.
 I took some transfers from this one today

your last picture makes it pretty clear that the mold makes the big fat clear mycelium on your green agar mix first.

Both of those starter plates are full of mold IMO - not worth trying to use.
I speak a little jive, but I couldn't quite figure out what he meant either

Ye the one with the swab in looks like there might be some of that clear mould already but the top looked like spore germination to me. Hard to tell. I have a whole bunch of pre-sterilised tattoo needles that I use. I flame them before every transfer

Ye it’s a disposable lighter I wipe it down with iso before use and sometimes in between transfers. But if there’s mould on the first plate from swab I was obviously doomed to start. How do I know if all my swabs don’t have this? And I know swabs and spores are inherently dirty so “cleaning” them up through transfers is the idea but that’s what I’ve been doing and I’m struggling to shake this stuff.
It’s strange tho you see the last picture of the green plate, that’s the first time since working with these cultures that I’ve seen some solid thick growth like that. And I don’t see any of the clear stuff on that one

If you look at the mold satellite on your last pic you can see the large "clear" outer circle that is also present on your transfers.
