First time everything. Spores to agar
    #26778405 - 06/24/20 04:46 AM (14 days, 4 hours ago)

Hello everyone! Thanks to MrBovineJoni user of this forum I get some spores.
I used light malt extract 10g, agar-agar 10g and nutritional yest flakes 1g to prepare ~400ml agar. I think using nutritional yest flakes was a  first mistake. They did not melted and after 20min of sterilization process there was sediment in a media bottle. The agar I poured was probably too hot (second mistake) which caused condensation on the petri dishes lids, so I tried to get rid of it by putting a dish with hot water on the top. It helped a bit. After that I transferred spores to agar. After 3 days I end up with this:







which looks like growing mold to me. Am I right? Is the temperature of agar and sediment in the media bottle the only reason of it? Can I 'save' this plates somehow or maybe that's better to throw them away without opening them at all?

That is mold yes. Toss em since your spores haven't germinated yet. Since you got it so quickly either something is wrong with your sterilization initially, or your technique during inoculation. Do you have other plates that you made that you haven't opened yet? Are they still mold free?

Don't get discouraged. My first plates grew nothing but mold too. Watch some SAB videos and practice your technique.

I've got plates with hawaiian and these ones with keepers creepers. Mold seems to be in most of kc plates, but it looks like spores have started germinated in these plates (looking from the bottom). Hawaiian have not started growing yet at all (there is few plates with mold, but not so manny as in kc plates). The agar I've used was same for both of them. I prepared 2 media bottles and split each of them for kc and haw.

Ok so if only those plates are contaminated and the rest from the same batch aren't it means that you messed up your sterile technique in the SAB. Probably let your hand cross over the open plate. It takes some getting used to for sure.

But definitely toss those plates you posted ASAP. The green you see are spores and you don't want those getting out in your grow area

Thank you for your help. I will get rid of these plates.

What about these ones?



I have got also a question about SAB. I've got a 60ltr box (I'm going to but something about 100ltr, because the one I've got is a bit too small) which I have used with 2 small rack in it. Should I use a towel too (below the racks)? Should I soak it in water mixed with soap? What about walls of SAB? I cleaned them with 70% ISO trying to move a paper towel in one direction. Is that enough?

Those plates look good. Take some transfers from the cleanest looking sections as soon as you can.

I personally do not use a towel but some people do. I don't think it matters too much.

Is this not a cobweb in these plates? How can I figured it out?

Once again thank you for your help!

Well not sure what your plates look like now. But cobweb isn't as white as cube myc, it grows much more wispy than cube myc, much less organized, and much, much faster. Along with some other tell tale signs.

Here is what I do:

Turn off house fan, AC, heat etc to reduce air currents
Wash the box inside and out.
Dry completely with paper towel.
Set box up with everything inside.
Cover tools with foil
Mist the inside of box with water
Wait 10 minutes
Success

IME it's more important what your hands do inside the box than how you clean it.

I will take some photos tomorrow morning. I'm a newbee, so I might be wrong. It looks like all of the Keepers Creepers plates are covered with coweb. They started growing really fast. It's been over a week now since I've transferred spores to agar. I have got plates with hawaiian and the ones with KC. And the difference between them is massive.

Looking good! In pretty much all of your plates I can see mycelium growing (others more rigorous than others).

That very fluffy Hawaiian looks a bit odd but that does not immediately mean it is bad. If you have some plates to spare for transfers, take a transfer from it and see how it looks like when it recovers.


If this the same KC I sent you (got it from Edmunter myself) - I would expect it to be growing quite  quickly (and also the weather has been very warm lately). But be careful as one of those richer KC plates has some mold on the side so try to transfer without dragging that along.

Thank you once again mate!

Everything on these plates is what I received from You (excluding mold on the one)

I noticed that darker area on one plate and I thought it does not look good. I have prepared lots of agar plates using the recipe you have sent me. I will do transfers tomorrow :smile:
