What am i doing wrong here?
    #4294667 - 06/14/05 12:20 PM (11 years, 5 months ago)

Alright, I steam sterilized a jar (1 pint) for 45 minutes. It was BRF/verm substrate. And about 3 days later, there was this nasty sour smell coming from it, so I identified it as contam, pitched it's contents. Is 45 mins for one jar not enough? Oh, and I don't have a PC, so I have to work with what I have atm, until I get one.

Steam is not enough to sterilize bacterial endospores. If I were you and I couldn't use a PC I'd steam the jars like you did every day for 3 days straight.

That should allow the bacterial spores to germinate and thus become possible to kill with 212 degrees.

My friend has been steaming jars and so far has 0 contams out of 11 jars. Four of those are in the pmp. 7 more are about 20% colonized. He boils them for 90 minutes, so I would say increase your steam time and you'll be ok. :cool:

45 minutes of steaming for a Pint jar of BRF/Verm isn't enough.

try 1 1/2 hours for a Pint jar.

Yea, when I did PFTek I steamed for 2 hrs, and lost 50% to bacteria anyway. There's no getting around how awesome it is to have a PC...


Edit: PS, I think my incubator being too warm had a lot to do with it too..
