Thank you for this video! I am working on water agar to clean up from what i believe to be lepista nuda (purple mushroom, fragrant, collected in november-december (canada), pale pink spores - very thick layer). I find that the mycelium is aggressive on card board but may be co-existing/contaminated with something extremely fuzzy - possibly mold. Using malt extract + yeast agar, it is hard to see the mold vs mycelium. even on cardboard, i see aggressive mycelium that looks like oyster mycelium, and other parts of the cardboard+tissue is something more hairy. hope to get that cleared up with water agar soon! i've wondered about laying a thick chunk of water agar just to see is the mycelium would grow vertically, leaving behind mold. ahhh agar work is fascinating!

Great explanation!

If we see the mycelium colonize the plate despite the contamination-- can we make an argument that this happens in nature and it will work itself out in the end? Could we potentially see that this is causing the mushroom to produce higher concentrations of desirable antimicrobial compounds? The fungi that grows from eating radiation comes to mind. Perhaps the stress from competition, radiation, or extreme conditions is a good thing? The strong survive right? What if we grew out the contaminated culture-- will it ever fruit? What if we tested for the mushrooms concentration of antimicrobial compounds-- compare it to a clean culture of mushrooms and what will we see? What differences do we see when we compare mushrooms from the wild to mushrooms in vitro? Could a clean fruiting body be produced and isolated from a contaminated batch? Could that mushroom have high concentrations of desirable compounds ?

it happens - from my skin, talking while working through these dishes - about 1% of all my work is contaminated by ambient organisms in the air but Im working on getting that down - it’s hard to eliminate completely that’s why qc and testing is so important

Hey Gary, thanks for another educational video! On the plate that looked fully colonized on top, how do you know that the bacteria isn't growing underneath all that mycelium? From the first Oyster dish, it looks like bacteria grows much more quickly than the mycelium so I assume that in the time that it took for mycelium to grow over the whole plate, the bacteria surely should also have done the same? Incidentally, do you have any experience with "embedded" bacteria? I seem to have some mycelium that I just can't separate from bacteria. I'm several agar transfers away from the first plate and still getting unusually aerial looking growth on both agar and grain. Thanks!

Informative as always! I do have a question regarding mating isolates. How long do you typically give them before deciding they're compatible? I've got several 12 day old plates, and each isolate has filled their half of the plate. They have met, but I'm not seeing any obvious signs of connecting. Perhaps it's still a bit early to be seeing this? I'm definitely not seeing a gap in between them, and they don't seem to be trying to avoid each other. Maybe I'm being a bit impatient heh!

@FreshfromtheFarmFungi

they should pair relatively quickly- if you don’t see any zone of inhibition they probably mated 👍

So mycelium can overtake bacteria that’s cool to know, if you see a bit of discoloration it’s not all over and throw out your jar or whatever which I’ve done before.

Thanks for you educational videos ! Really appreciated resource 🎉 Quick question . Is it mandatory to own a microscope in order to run through mycelial breeding journey?

Hey Gary trailering onto the question about going from LC straight to substrate; your answer mentioned backlog of substrates etc. that would indicate it was considering the context of a non-home scale. I’d like to reask that question but within the context of a home grower, doing maybe one or two mono tubs as a hobby without a specific necessary timeline and not a commercial activity, would it make sense to skip the grain spawn and just flood a substrate with highly myceliated LC?

@FreshfromtheFarmFungi

@@FreshfromtheFarmFungi TOTALLY. in fact, I expect since we're going from an assumed aseptic environment to one that's decidedly not, we can probably "strain" the mycelium in some way, perhaps with some of the substrate over a sieve, to better accommodate the desired hydration.

yes this is why it’s important to observe early growth stages and transfer to clean plates before contams are covered - the mycelium once colonized is strong enough to fend off contams but they can persist if they get covered later on - hope that makes sense (there are exceptions and I have seen people get away with a lot and have success but these are my strategies and how I do things)

I always wondered what would happen if you went ahead and transferred contaminated plates anyways. Does the bacteria show up on the mushrooms after they have rooted or what? Or do they simply not grow or what? I always throw anything out if I see contamination

How much time contam takes to show on agar

Hey Gary, thanks a lot for the info. I have two questions: 1. I put mushroom in petri dish, i see some bacyrriabgrowing in random places, but I also see ehat i think is mycelium, growing from 3 spots from top of mushroom, but it had bluish center. Is it because they're cubensis or this sounds like contam cuz mycelium is always white? 2. Why go from grain spawn in a jar to bulk substrate? Can I just open lid of the jar for grain spawn and wait for mushrooms to grow from top? Is the only reason for bulk spawn to increase the yeld? Thanks!

@FreshfromtheFarmFungi

Жыл бұрын

1. It’s hard to say, if it was from fresh tissue it may be psilocybin oxidizing to psilocin but it could also be pennecillium - you can tell with a microscope or further growth. 2. grain spawn can be used to fruit but it tends to get mutations and not as good of a pinset because of the high nutrients. Genetics is a big factor but usually sparse nutrients in a fibrous matrix makes better flushes. Im not sure if there is science on this but just from experience.

What if early on you spot a colony of yeast contamination and then further on in incubation you see your mycelium eating that contamination..would you use the plate or discard?

@FreshfromtheFarmFungi

2 жыл бұрын

I would transfer the fresh mycelium to a clean dish first and then watch it after for fun, yeast can wreak havoc on LC’s so I prefer to not risk anything being underneath the mycelium 👍

A lot of times you see what looks to be bacteria in your plates but also see that the mycelium is going to win, it doesn’t look nasty contaminated and if you wait the plates becomes totally healthy by look and smell. In this case is it ok to use this plates to continue growing ?

@FreshfromtheFarmFungi

Жыл бұрын

it’s best to try to transfer the clean mycelium before it comes into contact with any contamination to keep it sterile. It might look healthy but the contaminant can come out later in the process and waste all that time and effort. I say make sure it’s clean off the bat 👍

Garry I had a thought, what if we sterilized (grains + substrate) mixed togather and later inncoulate it with large quantity of LC ? I was thinking it would reduce the time it takes for spawn run.

@FreshfromtheFarmFungi

I have tried it and it works but it doesn’t reduce the time as much as you think and causes a back log of incubating substrates - there might be a good ratio but for 5lb blocks it’s better to spawn grains first

I had to stop growing all together because of the trichoderma in my area was so pervasive that I couldn't grow anything no matter how clean no matter how airtight everything was I was getting massive trichoderma infections I would have a perfectly colonized substrate almost ready to put into fruiting in two days later it would be solid it had perfect primordial knots and then bam it would be covered with trichoderma I gave up growing for all summer because of this! So now I'm going and testing all my jars of liquid culture to make sure that it wasn't coming from them or they didn't get infected So basically I'm I had to suck up liquid culture from the jar and drip tiny drops on to Petri dishes. This is something I've never really done before only with suspected liquid culture it is growing weird though it's growing like little snowballs all over the top with no real spreading of tendrils of mycelium. It's only been 4 days and I got very pervasive white snowball or odd shaped spots I don't know if it's because it's liquid culture cuz like I said I've been doing this for a long timebut I've never really tested at this stage I usually test each jar when I first inoculated and there's more or less spores in it not fully grown liquid culture so maybe this is normal I have no idea. I know eventually time will tell but I want to get growing again and I don't know how long it should wait maybe a couple weeks 3 weeks. What do you think.

@FreshfromtheFarmFungi

yes you can also do this under the microscope but it requires more training since you already know what trichoderma looks like on substrates it’s easier to see it on plates. It sounds like it could be coming from the bulk substrate. I would purchase some different brands and see if it goes away then revisit your bulk technique. Just my hunch but yes we have all gone through bumps on the road just step back and think step by step how you can test using controls to figure out the issue 🙏🏻🍄❤️

No noise cancelling is going to make much of a useful difference. That particular noise is going to persist and what you’d have to do to defeat it will noticeably impact the way he sounds when he speaks to such a degree that it wouldn’t have been worth the effort in the first place. A real low volume hum, intermittent might be worth working on but in this case someone without some serious technical skill and a ton of time to spend in post on these videos is going to be wasting their time. My suggestion to the original commenter is to get over yourself and either look for what you’re getting out of this or become knowledgeable on noise cancelling before suggesting to a creator how to change their content to suit your personal needs.
