Grr.. what the hell is this?

So this is my second batch of inoc'd agar plates and they are about 7 days old so they were sizeable enough for a transfer so this pic I took inside the SAB during the transfer. I transferred it anyway since it was already open but this sure isn't myc, so what the hell? I've done everything right up to this point, all 8 plates basically have this on it, I transferred 3 wedges from 3 different plates to 3 new PC'd plates and then said wtf is the point and didn't bother with the other 5 since that isn't even myc but whatever.. (Forgot to mention, I used P. cube syringes to drop 2 drops in the center of each agar plate when they were inoc'd)
please help, losing faith.

Bacteria. Try antibiotic agar

But I don't understand.. There is no Myc anywhere on this plate, or any other plate.. just bacteria. How is that possible, have my syringes gone completely bad? Can I reuse the 16 wasted mini rounds?

Spores can take awhile to germinate, bacteria is pretty quick to grow.

and how come this is the first time I've heard of antibiotic agar? Am I that bad at this that I have to use a failsafe method? lol. I followed every instruction to a tee

If It's cool with you guys, I'm going to need some more information. I don't want to do the antibiotic agar. Should I let these other 5 plates continue to try and colonize or
a) they might as well all be garbage? b) My sterilization and inoculation is by the book, so that can't be the issue, I feel it's my storage. I'm storing them on a shelf with just the poretape and wad of papertowel on the lid, but it is NOT enclosed in a ziplock bag or covered in cling wrap, is that why this is happening?
I feel like doing another PF tek, that was more fun and successful, but used up way too much of my syringes... I really want to get this one done right so I can transfer to grain

I put mine in sandwich ziplocs.
I put spore solution in 10 different petris and only had one colonize in a timely manner.
They might not be garbage, just put them in ziplocs/plastic wrap.
Let us see some pics

Hey thanks for your reply Mycologist. The pic on the OP was basically what they all looked like. I have already wrapped them all in cling wrap and put them back onto the shelf. Did you want me to do anything further?

Well they all are bacterial it sounds like. Try one drop of solution next time. How long did you pressure cook these?

It's just bacteria. Excess water in the cup, contam inoculant, improper pc cycle or bad conditions are probably the vectors. Toss them, wash them, try again. Might be your stringe tbh

I try to use plates asap. If I do store its in the fridge.
You say your inoculation is on point. We hear that a lot.

I've heard this said a lot, and I can't help but disagree. Excess water doesn't cause bacteria. Bacterial CFUs cause bacteria, same with conditions. If there's no CFUs you can have a flooded plate in 50°C. Nothing will grow on it.
The vectors have to be bacteria got in somehow. That could be inoculant, Pc cycle, or techniques. I highly doubt it's the PC cycle, I pc for 15 minutes at 15 psi and have never had bacteria pop up in any cobtrol dishes.

Yeah I would agree about the bacterial cfu being the cause and having to exist some where to cause growth. I have had excess water appear to be the vector for contamination. Water drowning the myc out causing poor colonization and eventually will contam.
Just trying to give some possible pointers to reason for contam, sorry if I posted any misinformation.

Heh, no worries I get it.
I pc the mini rounds for about ~45 minutes.. The PC has no adjustments, I believe 15 psi is just the standard for it. I just gradually bring up the heat, until it starts hissing and releasing pressure, and I leave it at that state for like 40 minutes then turn the heat off, and let it cool overnight. I then use those mini rounds right away or store in the fridge with cling wrap around it. If I do use them right away, they go into my SAB (just a big tub with 2 arm holes.. I use a damp towel and wet the walls slightly with soapy water to attract any floating bacteria. (I let the box sit for 10 minutes before I work in there to let the air settle). I then inoc them one at a time. I flame sterilize, wipe around the container with alcohol before I open it. Then when I open it, I quickly do the inoc, and close it back up.
Anyways, maybe the bacteria has grown, but if I give it another while, perhaps the myc will start growing, and I can take a piece of out it.. here's to hoping

ah. good job on doing it the right way
it could just be the syringe. i recently got a syringe from a sponsored vendor that was horrifingly dirty. the first batch of plates looked like i nutted into it. took 6 transfers for clean. ill also point out in maybe 10ish lifetime orders from the vendor i never had anything like that one syringe. thank god i got into agar.
those spores into jars would of shattered my cult confidence.

I've had a bad syringe before. I made my agar a little dry and put a drop on the center of the plate, and over the next two days or so the excess water disappeared. It had about 30 cfu's or so but they didn't merge together like yours. I just transferred as soon as I saw myc.

Can it really be a syringe though? I got 4 from a vendor, and the first 2 I used on a bunch of cakes, now im using another syringe. But I'll let these sit for awhile,
Do you think Myc will appear? even a little eency weency bit, I will extract

My personals petri dishes observations showed me that the quicker you see the mycelium developping the more you can suspect a contamination : mycelium trying to compete with the quicker conta ! In you case you I think you should already would have seen it ! "Do you think Myc will appear ?" <== no :p sorry.
Now, about your pink bacteria : I remember getting that a lot few years ago when using homemade glovebox. Without knowing exactly each stage of you preparation and operation, it would be near impossible to determine/pinpoint the exact cause. I understand you want "just" suggestions of what could have gone wrong and I don't come with much for the moment. When I was operating inside my glovebox, I remember over-spraying products inside it : bleach...alcool.... So everything in there was so wet that I ususally sterilizate some pièces of cloth at same time than the jars.... so i can wipe a maximum! I repeat : This was in this period that I saw thoses pinks colors in agar-agar.
No more since I use a laminar flowhood.
Last advice : practice and practice and try to take a walk in a park and force you to think about it : then you should success !
Courage
