Lion’s mane: Blue mycelium on agar
#26861285 - 08/03/20 05:33 PM (3 years, 6 months ago) |

Hello, I am new to posting as well as cultivating; so I apologize in advance if the images were uploaded incorrectly. Shown here are 3 agar dishes that are being colonized by Lion’s Mane (and possibly an unwelcome mold?).
The first one is the parent dish that I inoculated with a liquid culture. I have cut a good deal of contaminants out, as well as cut some out for transfer to the other two dishes. The other two dishes are a result of the transfers. The agar was made with barley malt extract and nutritional yeast.
Question 1: Why does the mycelium on the two transfer dishes have a blue tint?
Question 2: If this is contamination, how do I salvage the growth? It doesn’t look very localized.
Question 3: Why is the mycelium growing so irregularly on the transfer dishes? Is it due to an uneven dispersion of nutrients? How can I prevent this?
Question 4:Why is the thick, blue, uneven growth lacking on the parent dish? It looks evenly dispersed and white.
Question 5: Does the parent dish look dry?
Thanks in advance for any help provided. Please ask questions if additional information is needed to properly advise me.

Unless every one of those spots is a place where you transferred agar, I’d say you 100% have bacterial contamination.

Start over all of those spots are mold.

Thank you for the timely reply, one less thing to learn for me! Thanks a lot.

You have a wonderful collection of mold mold and more mold! Beginner tip, every mycelium is pure white. Makes it easy to spot any kind of contamination. My advice? (And this should answer all your questions).. start completely over. Maybe you can somehow pull off the impossible and get a pure dish after a dozen transfers but youre going to waste time, agar, dishes and money. Just get a LM liquid culture syringe, inoculate a ton of grain jars and use the last few drops on a dish or two. Thats how I start my dishes. Usually pure mycelium from the get go, if not Ive had to transfer like twice at the most. Youve just gotta scrap that contamination nation and start over brotha! Good luck! 😊✌️

This is fair advice I appreciate it. But why ditch the parent dish? Is it also contaminated?

Don't ditch the parent dish. I would assume it is ok. Sorry I should have been more clear.

Are you sure there is LM mycelium on that parent dish? I don't see anything on it. The dish should be white.

I have all white petri dish... but I just cannot transfer it - it doesn't want to grow. Any tips?

OP, are you using a SAB or flow hood?
That's a LOT of mold spores that got in there

Typical LM, pins generally form (right of center) before full colonization of the plate.

I use a SAB and I thought my sterile technique was sufficient enough to prevent severe contamination; though this is obviously not true.
I always wash my SAB with soap and water, always closing it asap, and keeping closed as much as possible. I wipe everything with isopropyl alcohol before putting it in the SAB, and also give the SAB some sprays of isopropanol. I always heat my syringe red hot. I attempt to keep the dishes closed as much as possible. I always wrap cleanly with parafilm and I store the inoculated dishes on a very high shelf under a small lean-to to prevent excessive airflow. All my poured but “uninoculated”(?) dishes are stored in my refrigerator dedicated to mycology and other sensitive practices (so no food).
Any additional tips or is there anything I’m missing?

Conservation of motion is key within a still air environment. Try to move less with greater efficiency, you may be stirring up turbulence with your arm/hand movements.

Do you wear gloves? Might make a difference. Other than that you may want to try using your SAB in a diff room. If youre still having problems you can clean and place everything youll be working with in the SAB, then seal your arm holes temporarily and let the air settle over a few hours while keeping it in a room with the lowest airflow possible. Cleaning the room that you use your SAB in is as important as cleaning the SAB! Good luck my friend.

I pretty much guarantee that you're going to need to slow down, be more aware of your movements. Try to be aware that every movement will disrupt the stillness of your box, picture it being filled with smoke and how that smoke would swirl and create eddies with each motion, the key is to keep those eddies to an absolute minimum because they're going to carry airborne contaminants. Spray soapy water to trap spores to surfaces, use a dish drying rack to keep your work surface above the contamination on the floor of the box.

I always wear nitrile gloves in addition to the heavier duty gloves I have secured to the inside of the armholes of my SAB. I always clean the SAB gloves thoroughly. My SAB is completely sealed from its external environment when closed. I also always close the supply air vents in the room. I may move rooms though, I typically do it in my kitchen (most space and best source of water for cleaning).

Boom, that right there is your issue, get rid of those gloves attached to the arm holes.

Agreed.
I never did like that perma-gloves inside the box idea...
