contamination question
    #22462301 - 11/01/15 01:16 PM (8 years, 2 months ago)

Hello...

I am struggling with a contamination problem.

Cubensis in franks monotubs... been doing it for a few years.. somewhat low yields... only getting 1-2 flushes before mold.

So I attempted to learn agar... and wasn't careful enough looking for contamination on the petri dishes. Turns out, I have a fluffy white contamination that now has become dominant in everything I do. It seems to grow faster than the mycelia. I even made spore prints and I grew them out on agar and it looks like the fluff is there as well. I have old LC, tissue samples, old spore syringes... more than 10 agar dishes going, dreaming of something growing without the mold... its not looking good.

Has anyone else run into a contamination that was difficult to separate from the mycelia because on its speed and aggression?

Might need to start all over...

Did you smell the spawn before adding too bulk? should smell like fresh mushies, silly question but since you went from spores are you sure it isnt mycelium? if its a persistent contam you could clean the room you do agar work in, repaint the walls, clean carpet (or bleach floor), start from fresh spores and try again, the same thing happened to me with black mold.

Post pics. The answer to your question is yes, everyone runs into contam issues from time to time. The key is to eliminate the vector and we can't help you do that without actually being able to see what you have going on.

My apologies for the poor language skills. On the agar, people often take a sample from the leading edge of growth in an attempt get a clean sample, away from the nasties. I'm finding a cobwebby growth that overtakes the mycelia. Making it impossible for me to get a clean sample.

Here are two pictures of my petri dishes, and one tissue sample grown out in a ziplock bag (the large, long tissue). I have had success with agar before, with beautiful stringy circular growths, but these petris are all fuzzy. They originate from a tissue sample, then one transfer. I've made more petris from the ziplock sample, as you can see where I grabbed some mycelia.

That is all weak. Clones that look like that are either full of mold or have no vigor (those transwers look like they are all mold). Either way the end result is trich.

Clone younger more vigorous pins and the culture  will be easier to clean up.

Oh wait, those two petris were from direct tissue samples, I can see the chuck in the center.

Dang.... this is all I got now. I got nothing clean anymore. I guess I'm back to ordering a spore syringe online. Has there been a supplier that has been shipping vigorous spores? I was having some bad luck two years ago with dead syringes.

Bummer!!

Take prints next time and do more research into proper cloning. Vigor is gained and preserved via good techniques, not from the spores themselves. I bet you cloned an old fruit, clone young fruits instead.

Just curious, do you feel that young clones end up producing more vigorous, healthier strains, or simply that they are easier to clone since they switch back into normal mycellial growth more easily?


--------------------


I spawned some popcorn casings and had double-overlay cause I didn't put enough hydrogen peroxide in my automated aquarium mister.  I only got one mushroom so I cut off the head part where the seeds fall from and put it in a jar of LC and sprayed it all over a tin of PF cakes I made with gravel, cardboard, and bisquick in my microwave.  I think it will be good cause B+ is so potent.
Triggered yet?

Only a square would say "a cube is a cube."


No, this does not look right...

Easier for the most part but even the best genetics won't do well if they get old.

I have spore prints growing out, but they look contaminated as well~ My last grow was completely overrun with this white fuzz. I took prints, but I wasn't feeling like I could get clean spores. This is the reason for my post... It seems that this fuzz has closed my chances of getting it clean.

The tissue samples were from young mushrooms, but they were visibly inundated with fuzz.

I need help!! I've had no good clean agar growth for months... I broke down and bought spores online, cleaned everything, and made four agar dishes with the syringe, and it looks the same as my other cobwebby agar dishes! Fuzzy, slow growing and nothing like the ropey fast growing mycelia I've grown on agar in the past.

I guess my sterilization is not up to par.

Here is a photo of one of my newest petri dishes.

Help!!!

Its not the sterilization. Anyway that last plate doesn't look to bad. Make a transfer and see how it recovers.

Where is the best place for me to read about what I should be looking for. Its my understanding that there are two types of mycelia, ropey and softer looking stuff. I had ropey looking mycelia in the past.

And this is growing so slow. Thats two weeks from when I saw it begin to grow. 70 degrees.

Thanks Pasty for all the help on this. Its grinding my ego to a new low. Maybe I'll get to a better place after this ~
