Im not sure what kind of contam it is but it seems nasty. What I would do is scratch the substrate into a plastic bag, seal it up and throw it in the city trash can. You can just soak the jars in bleach and re use them

aspergillus niger, its not as bad as another one but it still produces those anflatoxins or something like that highly carcinogenic

wear a mask, dispose of them that way. Or just throw the jars away.

The best thing is to simply throw the jars in the trash and buy new ones.

If you are determined to save a few bucks, the next best thing is to pressure cook them again for an hour at 15 psi. This will kill the majority of spores, endospores, bacteria, etc. Once they have cooled, don't wait around before emptying them.

Drop the jars, unopened, into a sink full of warm water and bleach solution. Give the water time to seep into the jars. Avoid any air bubbles coming out of the jars because they could carry spores. Once the jars have soaked for a while, open them underwater and empty them out. Wear rubber gloves while doing this. Don't flush the contents of the jars down your sink drain, or you will be calling a plumber to fix a stopped up drain.

91% iso is, I think, more antimicrobial than the 1:9 bleach:water... I'm not sure tho :smile: If you try it and your stuff is soaked in it, you've also got the "incinerate" option immediately available with the light of a match :smile:

I too live in a small apatment and I open mine inside a gallon ziplock, remove jar, lid, and ring and wash with antimicrobile soap, then immediately into a hotass bath of generous bleach AND antimicrobile soap to soak for and hour or so then immediately into the p.c. to cook for a hour and a half at 15-20 psi.It's worked with 100% sucsess so far. I cuurently have 5 quarts colonized @80% ...so far no contams! :grin:

Re: Proper disposal of contams - IPA vs. Bleach [Re: JohnnyRespect]
    #1508291 - 04/30/03 05:57 PM (13 years, 7 months ago)

Actually, while in *theory*, alcohols (IIRC, ethanol is better against a broader range of bacteria than isopropanol; I don't recall where methanol falls on the scale, but I think it's <= ethanol) are better at killing bacteria than dilute solutions of sodium hypochlorite (because of sodium hypochlorite's tendency to be 'deactivated' as an oxidizer by too much organic matter, and depending on the level of dilution), in practice, it is generally considered superior -- especially because, while IPA *will* kill bacteria, it isn't known as being terribly effective against fungal spores (at least not with a single contact).

Bleach, and Lysol (old/industrial grade: phenylphenol, new/commercial grade: ammonium chlorides, ethanol, etc.) are known for killing just about *everything*, with sufficient contact time. Time is dependent upon the concentration (both of the disinfectant solution and the thing you're trying to kill), the surface (porous/non-porous) and what it is one is trying to kill. Spores, on average, take longer to die than do bacteria...And both fit into the definition of the word 'microbe'.

Also note that, for particularly hardy microbes, prolonged contact time is usually necessary, no matter *what* the disinfectant; for non-viral nasties, 2-5 minutes with Lysol or bleach is usually adequate; for viruses (e.g., Hepatitis X) half an hour or more is recommended (not that Hepatitis is any sort of a common thing in this hobby - merely using that as an example of a particularly robust virii).

HTH,
