 Contamination Survival

i got some BRF/VERM jars going and i noticed today(day 7 since injection of spores) that i have some yellowish mold growing. up close, it almost looks powdery. this growth is in areas where the jars were not injected. i didn't use a pressure cooker to sterilize these, i used a large pot with water and cooked for an hour and a half.
could this be a contaminant that survive my cooking? could i have not cooked at a high enough temp? when i cooked, i just let the water stem, it only had a few bubbles coming up here and there.
next time i cook some up, should i cook at a temp where bubbles are coming up and for 2 hours? could i have avoided this?
thanks.

I boil my jars all the time. Put a washcloth on the bottom, bring water to a boil, then reduce to a simmer. I always have a second pot of boiling water ready at about 45-60 minutes and then add a few cups of boiling water to replace what was lost to steam. Keep it covered until it's cool to preserve the sterile environment in the pot. So far, I've done dozens with this method and no problems (knocks on wood)
It looks like that mold started at the top though. If you are using a glass, it's possible you made some mistakes (wet verm layer, bad seal, etc) What altitude do you live at? Water boils at lower temps in higher altitudes (Boyle's Law) That said, I've seen people do it with water glasses it's possible but more susceptible to contams.

i just noticed that the 4 contaminated jars(out of 6 total) i have, where all boil in the same pot. the other 2 that show no signs of contaminants, were boil in a different pot. im guessing i didn't boil them at a high enough temp. i threw them out and will redo tomorrow.

the mold is actually all over, but mainly in spots where i didn't inject. there is mycelium growth where i did inject though. i live in oregon, so, a high altitude...never did think about that. wont the substrate inside of my jars boil if the water is boiling. everytime i try to boil with a normal boil, i end up with a thick mush filling the bottom half of my jars.

If you are using glasses that could be the problem you don't want mush in the jars. Sounds like your 'glasses' aren't sealed well enough. Before and after cooking my jars are somehwat like damp beach sand, not soggy though. Like I said, it can be done with a water glass--but I would follow the PF Tek to the letter, and that includes jars for us noobs. You really can't go wrong with that tried and true method.

You'll have a much better success rate if you get yourself a pressure cooker.
