Contams?? To toss or not to toss? THAT IS THE QUESTION!
    #3468829 - 12/09/04 04:24 AM (12 years, 3 months ago)

I knocked up my 1st batch a couple weeks ago and some of the jars had a yellowish color and looked almost like the cake was deteriorating.  There was weell developed myc on about half the cake but the yellow and a couple with small green spots made me just toss it. 

When i threw it in a bag with gloves and plenty of lysol in the eviroment but as i carried the bag to the porch it smelled like fresh mushrooms.  Did i toss them prematurly?  What could have i done to fight the contams? 

I have looked thru all the contam pages and haven't seen anything like i've seen on some of my cakes.  It looks almost as if the cakes have been eaten away by this yellow dusty residue usually in between myc patches?? :tongue:

that doesnt sound good. If its yellow on the myc and myc alone then its possibly myc piss but if its (and it sounds like it is) on uncolonized substrate mainly, its bad. You could have smelled the myc and smelled mushrooms but its probably no good..

I only ask becuase i didn't intentionally smell anything it was an arms legth away but smelled very mushy. The spots where on teh uncolonized spots but during nocing it was totally sterile and i kept everything very controlled, so i dont' know how so many would have been contamed. The only thing i was thinking was i didn't realive that between each cakes nocing i used a candle and peroxide to clean the needle but later read that candles burn dirty, thats the only thing i can think of. Evertthing else ws so precautionary that i can't see where this came from or if it could really be so harmful.

Also peroxide wont kill molds or bacteria, you need to use alcohol. It sounds like needle sterilization is your problem...

If the mycelium consumes the areas your unsure of you can also bet that its not a mold..myc will never win (at least almost never..I've kept many dozen jars seeing and none ever have, guess you can never say never though) in the battle..

You know pics would help alot to determine whats going on here... Either way if it colonized with mycelium completly chances are very very good that its not harmful and not a mold. If it is a mold or bacterial thing though its quite possibly harmful and you shouldnt mess with it anymore if you determine thats what it is other then burying it outside somewhere in hopes for some outdoors next season.

Bah, I'd say a good rule of thumb is that if you've got 2 irregular colors, one of them being green, you just toss it :wink:

If its green definatly toss..I only saw that it was yellow, was there mention of green in it?

White is good (grey is not white..it must be white), blue is ok (it can look greenish but the blue will be ON the myc, if its not on the myc its bad), and a little yellow can be ok (yellowish watery discharge from the myc). Any other colors are definatly bad..

Actually it will, especially if using straight 3%. It just takes more TIME to eat it away. (throw a moldy piece of bread into 3%. let it soak untill it stops fizzing.)
3% peroxide will kill mycelium also, given enough time.

Alcohol is a faster more thorough method of sterilization.

No it wont..I've done it (not with bread but 2 casings)..it took 35% concentration of h202 to kill the mycelium and mold on the casings and it also takes a while soaking in it (when it stopped bubbling like you said). I've done it with entire contaminated casings. 3% is not enough..plus we arent talking about soaking, were talking about wiping a needle down.

Not to mention alcohol will evaporate almost immediatly. H202 could remain on the needle and get in the substrate and work to destroy your shroom spores. This is a bit of a stretch but could happen.

Edit:
Reason being by the way that mold and bacteria will produce enough peroxidase to break down the little h202 that is in a 3% mixture and turn it into just water. Now there may only be a bit on the needle so 3% MAY kill it but I guarentee alcohol will and 3% only MAY on a needle. you can soak a casing in 3% h202 though and it will survive (at least after a 12 hour soak, it did stop bubbing) The mold also survived..

Is alcohol a substitute for H2O2 in all instances?

No because alcohol will harm mycelium. H202 in small amounts wont. For sterilization alcohol should be used as it is far superior then 3% h202. That is for wiping down containers, spoons, needles, any tools er whatever. I put alcohol in a spray bottle and have a regular bottle of it..spray bottle of alcohol works great for casing containers.

Anything comming in contact with mycelium should have h202 added to it which wont kill much of anything but spores. Stuff like your water you spray, humidifiers, and dunking stuff.

Iodine can be used as a substitute (in much smaller amounts like a few drips per gallon, PM Hyphae or ask on the board for exact amounts, I havnt used it personally) for h202 in I believe all cases. I'd ask about that to be sure though..I think Hyphae uses h202 with something though iodine mostly.
