PC Contamination

I inoculated more jars of rice with a previously fully colonized jar. Some of the colonized rice turned dark blue/black. Is this bruising or contamination? I am thinking bruising because the grains were totally colonized but I am not very experienced. Unfortunately, I do not have pictures at the moment.

I have a photo available now. The top portion of the jar is the colonized rice that was added to inoculate this jar. The colonized rice was pure white and uncontaminated before it was cut out to inoculate this jar. Very shortly after it was added, the white mycellium turned dark blue/black. Is this bruising? The dark part is not spreading and the rest of the jar is colonizing well.bruiseorcontamination.jpg

Just keep growing it. I've seen mycelium kick the fuck out of trich given time.

Sometimes you get the mould and sometimes the mould gets you.

Thanks for the advice! I suppose it can't hurt to let it go. I'll find out if there are any problems when it is time to open it up.

i think its deffenately mold. iv been growing for a few years and frow what experience iv had is its mold. this can occur from needle inocculation or un sterile jars in your case its probobly from having unsterile tools while seperating the origional brf cake for curther colonization. keeping them on the other hand is possible when the new cakes are fully collonized u can cut out black sections and break the cake up with steralized gloves into a small mixture of coir verm, and pearlite this will increase your yeild and protect your mycelium from further airborn containants. tho any mushrooms which grow from the black will be more slimy, dark, and fragile. this fruit might make u sick so i would toss any that occur. if your jar feels wet and mushy or the black covers the cake i would advise u toss this. this may damage any other cakes your fruiting with. i hope it helps feel free to ask any questions.

Looks like mold too me as well.

I would just toss it if I were you..


Tip:
If you want to keep your jars just PC/steam sterilize for 45-60 minutes then empty out the contents.

That is unfortunate. I think I'll let it continue on for now just so that I can gain experience with what contamination looks like.
