how long do unninoculated sterilized jars take to contam in your experience?

I had like 20 sterilized jars that I couldnt get around to inoculate for just shy of 2 weeks. When I was ready I noticed they all took on what seemed to be cobweb mold and had to toss them. I thought ive heard they last longer however ive.never waited this long before myself.

It should be very few that contaminate and if they do with bacteria if they contaminate with mold you didn't sterilize them.

Hmm brf? I would kind of think they would just dry out before contaminating... unless they were moved? I'm pretty sure I had a wbs jar that I didn't use for two weeks... no noticeable contamination

I typically leave one uninoculated as a control. If it gets contaminated then I know I fucked up sterilization. If other jars get contams but my control does not then I know I screwed up during inoculation. Science!

You can cover the filters, I used to use jars with no filters. I have jars with no contams and I have no idea how old many are, some could be 10 years old, definitely lots 5+ years old. I found another few just the other day. I used to keep them to test out if my more unusual sterilization attempts would work. I stupidly did not date most of them, or keep notes.

I suppose if you cover the filter they would stay longer but I noticed slower colonization time from letting jars sit sterilized for 10 days before g2ging.
5-10 years, damn. You don't plan on using them do you lol?

Our grain sterilization is based on a SAL(sterility assurance level) of 6 log reduction 10E-6 but we also have th assumption that there's 10E6 CFU before sterilization so it takes 6 logs of kill to get to theoretical 0. Sanitation is 3-4 logs 99.9 99.99 kill but not good enough. After 6 logs to theoretical zero the industry considers sterilization another 6 logs after the CFUs are killed to get a 10E-6 jar that means there's a 1:1000000 chance of one CFU per jar. If sterilization is adequate. If you sterilize say to 10E-2 there exist a possibility that 1:100 jars may have 1CFU. If you sterilize a jar theoretically it shouldn't contam. But grains are tough to sterile since there not liquid media.

Hey, I need a job. I'm a pretty smart feller'!
OP, It sounds like it was a good thing that you didn't inoculate. Now you know to re examine your sterilization techniques. There's always a silver lining.

I have 1 year old WBS and 2 year old PF Tek jars that I never inoculated without any 'visible' signs of contamination.
Bacteria doesn't always 'show' though.

Oh and my above comment is not an endorsement for prepping a butt load of jars of head of time.
I have inoculated jars over a month after they were PC'd with decent results. I can't say I noticed a difference from the ones I inoculated the day after sterilization but the results weren't any better either.

Idk why we're always seeing this question. Is it not obvious that the best time to a jar is as soon as it cools from the pc cycle?

I think some people sterilize 12 then find it difficult to stretch their syringe to more than 10. I use three holes instead of four, works fine

Well you can plan to shoot up 12, but it takes a steady touch to only give 1/4cc per port.
10cc / .25cc = 40 shots 40 / 4 holes = 10 jars 40 / 3 holes = 13 jars
Gives you a little wiggle room

Yea. How about chevy's suck. That's a poor man's car. You can build a 350 way cheaper than you can build a 302. And i won't even to start talking about a porsche engine.
The point was if you have jars leftover, figure out a way to use them. And if you can't, then FOTTSE

Found On Road Dead. Ford is a one trick pony, if you'll pardon the pun =D
I'm pretty convinced Ford's engineers design their car's to fall right apart after 100k. But nah, I never really rebuilt one, I just wanted to say something technical after bodhie's jargon. I'd LOVE to restore a 69 Impala though...
But! Back on topic, I agree, have a little foresight before you set to work... But in my current state thats the pot calling the kettle a whore.

I think we all missed a possibly important question here... What kind of filter do you have on your jar lids?
