I have some oysters I put to grain today. My question is on masters mix. Do I pasteurize it, or just run the bags through to PC and sterilize?

Agar contam troubleshooting

What info do I need to give you to get input on what's causing the yellow color and lack of mycelium growth?

That looks like a culture of nothing but slime mold to me.

It depends on the supplements really. I’ve used alfalfa pellets in my “masters mix” instead of soy hulls, and they come heat treated. Anything that isn’t pelletized gets sterilized

Never heard of it.  What's BTI?
I wish I had though cuz those damn yellow sticky strips get on my nerves.

I've got the stupid little flies in the drains of bathroom sink so I definitely want to take some preventative measures just in case they decide to migrate on over into the grow space.  which is in the same bathroom.


I just got my grow room all filled up with projects so this is like a five-star Resort for those little buggers if they notice their neighbors with it.



I work in the pool service industry rn. I've got a bunch of DE (diatomaceous earth) 

Just curious is that stuff good for anything In this hobby? I know it is used in gardening but don't know what for.

BTI is BACILLUS THURINGIENSIS ISRAELENSIS, you get various Bacillus bacteria that are used to combat certain insects.

LOL OK!

Agar: oatmeal soak water, a bit of corn syrup, stick agar (I've gotten malt extract since then and will change the recipe going forward)

PC'd agar in InstantPot 45 minutes, poured into condiment cups in SAB. (will use glass going forward)
Let sit for a few days
Heated homemade steel wire spore spreader in alcohol lamp til red hot, cooled in separate agar pot inside SAB
Swabbed homemade spore print, made first spread in container
Re-heated spreader, cooled, made 2nd pattern in container

For the container pictured I think I only did 1 pattern.

I will make changes to my agar recipe and containers (plastic -> glass) but the data point I'm thinking about now is that the agar pot that I used for cooling the spreader has no contam, whereas ALL of the inoculated containers do. I guess that points to the spore print?? Or the water I used to spread. Is this reasoning correct?

That's bacterial so either you aren't sterilizing your loop fully or your water is not sterile.

Those are some options, generally speaking satellite molds are more attributed to our own technique issues.

You mention water used to spread...but nothing about preparing it. Did it go in the IP along with the agar media?

In any case, you can skip the water and remove a possible contamination vector. Just cool the loop in the receiving plate (no need for a separate cooling dish either), pick up some spores with the  agar-wet loop, and streak on the plate. A sterile swab works well for this too - it's more wasteful but also a little less fussy.

Even if the print is dirty, avoiding adding water may give any mycelium that germinates a better chance of outrunning present bacteria long enough for you to take a clean transfer.

Thanks so much, this makes a lot of sense. I boiled the syringe in water and sucked up some of the boil water, as I saw in a video. However, I also stored it in a ziplock in the fridge, so even though I heated the needle to glowing, there's enough doubt in the rest of the process to point the finger.

I'll look for sterile swabs. I want to avoid ordering things like lab equipment but that should be safe.

You can sterilize cotton swabs by wrapping normal ear buds in tin foil and pcing them in a sealed jar.
