Four outta five ain't bad...
(lemmy.world)
Day 4 of growing Pleurotus ostreatus cultures from spore. Only one plate got contaminated, but it was bad. There are two contaminant fungi going to battle, and around three possible bacterial colonies. I must have been losing it at the end, haha! Can't wait to see how they progress!
Yeah! And when they do meet, they form a new anatomical structures called 'clamp connections', so if you have a microscope it is easy to check if the mycelium has already mated.
There is a nice series about breeding and how to isolate single-spore haploid mycelium here: https://www.youtube.com/watch?v=vsJpjQhsDIM
The idea is that if you manage to grow plates from single un-mated mycelium, you can then control their breeding, and this is how you can make new strains and have more control over their genetics. It is a more advanced topic in mycology, but a very interesting one to learn about!
Thanks, that is fascinating, I'm definitely gonna check that out. No microscope yet, but it is on my list of things to obtain, although a proper HEPA filter and fan/motor will come first though, haha! Kind-of wondering if I should switch majors, but I'm already in my 400 series engineering classes--oof.
