Cambodian Contamination Problem =(
    #4097348 - 04/25/05 11:42 PM (11 years, 7 months ago)

I'm on my 3rd batch of cambodians. I made this batch with some Creeper (Same substrate, same Pressure Cooker, etc.) and out of 3 batches of cambodians, this time I have a single surviving jar. The rest have fallen victim to the blue-green mold (The creeper are doing completely fine). I'd give pics, but everyone who could probably help me on this probably knows what blue green mold looks like (Or at least I'm assuming they do).

I PC for 45 mintues to 60 minutes at 15 PSI, I use ~ 1/4 BRF to Verm combo, and the rest is history. Can anyone think of anything?

hmm... try several of these ideas that i have been thinking about....

**use lysol to steralize the air, specially before fanning or anything during hte casing...

**use the myco enviro bag for the inocculation. almost 100% contamination free... then you can transfer to a casing

** be anally sterile while making your casing. microwave the hell out of it, lysol the air, soap your hands ect....

other ideas?
make the condition bad for anything outside the jar, casing box , chamber ect. what i mean is... keep the rest of the room at a low humidity level to stop external bacteria growth. this is if your casing/jars can have proper humidity inside their area though

I'm not anal enough about contams to use a glovebox yet, although I would like to have one, I thought about it already, would probably solve my problem though.

This is a *really* good idea, but won't I be looking at some possible mutants? (I have nothing against handicapped mushrooms, but let's face it, they are ugly!)

maybe you can better identify your contaminant  here
if it's penicillium, i can assure you that you don't want that laying around!:dead:
when you get a chance, look at some of the symptoms of the mycotoxins in some common contaminants  here
"I PC for 45 mintues to 60 minutes at 15 PSI,"
it could not hurt to try 90 minutes.
are they spores from a previous grow?
if so, ever had any problem with contamination?

theirs alot of variables involved that you didnt mention.

First thing i can tell you is that your PC'ing too long. Biologists are taught to only PC something 15psi for 15 minutes to sterilize, although most shroomers are taught for 45 which is excessive, 30 mins is good. you could be drying out your cakes which hinders mycellium growth, im not sure what effect that has on contam growth.

either way, make sure that any holes in your lids arent exposed, do this by putting a layer of tinfoil over the lid and tape/polyfill over the holes. make sure the seal on your lid is good if your using jar lids.

as long as your following the innoc PF procedure, i dont see why you should be having any problems. you are flaming the needle after every insertion into the jar right?

if your doing everything right, i recommend getting a hepa filter. also, throw some desiccant in a container in your innoc room a few days before hand, it helps lower mold concentration in the air.

more likely than not, your innoc conditions are bad. you are one big contam.

could you show me info supporting this abermelin?
reason i ask is that i have heard otherwise for some time and i'm curious what you're source is.

Actually this does look a *lot* like penicillium... especially in this pic they presented in an example. It completely fits the description, too. http://www.shroomery.org/images/23418/green2.jpg

Give me a little bit and I will post a picture.

Let me answer the details that Abermellin posed, first, though.

I can say for 1, that the jars are definitely not dehydrated. Not to sound too blunt about that, but they are not getting dehydrated.

Quote:

I follow the PF tek almost by the book. I inoculate through a double layer of tin foil, and then place a layer of sterile foil over the top of that (All pressure cooked with the jars)

Quote:

you are flaming the needle after every insertion into the jar right?




No, but I do flame it till red after every other insertion to a different jar. The PF tek calls for it every 3 jars, so I feel I'm being fairly good about it.

do you wipe it down with alcohol between each inoculation?
if not, this is most likely your problem.
did that myself one time.

i'm serious about that penicillium, though.
GET IT OUT!
it's sporulation is airborne and ubiquitious(fucking everywhere)
you could risk permanent healt risks including
respiratory and neurological damage.
NASTY STUFF! (no more smeling)

Here's a pic of my problem. It's not but in the early stages of development, but it looks a lot texture and color wise to the picture that I presented from the examples. It also has an ammonia/vinnegar type smell to it.



Enjoy!

Wipe what down, the needle? Nope. I use fire to sterilize the tip.

get a clean alcohol soaked paper towel to wipe the entire needle down.
use flame when you begin to kill anything inside the needle, then cool it with the towel.
this almost surely your problem, i'm afraid.

with those jars-
fill the sink up with 50/50 bleach and water.
submerge jar
open, and let it sit under water for the better part of an hour to kill your contaminants.
dispose and then soak your jars in a 10% bleach water sol. for 12 hours
dishwash
start over and remember your experience.

that's not the one good jar is it?

no, that's not the good jar. The jars that are surviving are thriving, rhizomorphic mycelium. I can't wait till they are all grown up *tear*. Too bad only one camb jar made it though. I'm excited for the creeper, however.

Will Peroxide work as opposed to bleach or alcohol, you think? I'm going to get some lysol next chance I get as well.

no dice on the peroxide.
i'm sure you could use alcohol, too, but i stopped using that for the disenfection of equipment some time ago as it is not practical.

great as a surface cleaner in a spray bottle though.

agar reccomends the use of white vinegar and hydrogen peroxide, separately.
spray one, wait a moment, then spray with the other.
he said it will kill ANYTHING.

Did you make up your own syringes? If you did and you didn't use a glove box I would say that's where your problem lies.

i have not used lysol once. no pressure cooker, no H2O2, and no glovebox.

but if you do, just wash your hands, pay close attention to everything you touch, and whether or not any sterile surfaces touch any non-sterile surfaces.

0% contamination i promise.

Under his instruction, I taped drumsticks to his head and turned him into a sort of mummy, or perhaps a caterpiller in a cocoon. He remains this way for about three hours, making bizarre noises, pretending to be a new species that must learn to walk and talk and eat, etc. And he communicates with other life forms by way of the antennae on his head. Eventually we jam a tube from a waterbong into it's mouth and figure he's learned all he needs to know.
