How long should I leave my cakes? & other contam questions
    #13018475 - 08/07/10 06:36 PM (14 years, 5 months ago)

I have spores on the way, and I'm about to start making my PF cakes, but I have a few questions about contamination:

1.) I read somewhere I should leave my jars alone for a while after sterilizing but before inoculating, to observe if any bacteria or whatever grow. I forgot how long it recommended, though - a few days?

2.) If any weird colors appear, or if growth of the mycelium stops, it is probably contaminated and should be thrown out. Right? Is there anything else I should watch for?

Thanks.

1) No need, but you can. Or leave one jar unshot as a control.
2) Be careful throwing out jars because 'growth stopped'.

Which version of the tek are you using? Remember to take the foil off the jars after you shoot.

You make it all possible. Doesn't it feel good?

Thanks, Dr. T!

This one, as well as RR's video series on the PF tek. Foil off after inoculation, right?

you take the foil off after the jars are cooled down BEFORE you inoculate them!

The vermiculite barrier will be enough to keep your contaminants at bay, make the 4 holes in the top no wider than the size of your syringe. You will be fine.

either way i think it doesn't really matter much, i take the foil off when the jars are still warm just so that the moisture on the lids can evaporate.

Gotcha, rave; thanks. :-) The only part I'm not sure about is avoiding contamination... or spotting it, rather. If the mycelium fully colonizes the cake and there are no weird colors, it's guaranteed safe?

you'll know a good cake when you see it. It's a nice sight, all white looking. There should be nothing else growing in there, it's pretty safe once full colonization is reached. i'd worry more about uncolonized spots on the cake.

Personally, i let the jars sit for at least 8 hours to cool down, and either use them as soon as i need them (usually right away) or cook up another batch so i can inoculate them all at once. Either way, i think you do not need to let them sit to watch contaminants grow on them. The fresher they come out the pressure cooker the less chance for contaminants to settle in there is.
