Mushroom Skin Best combo


#1

Hi guys :slight_smile:

Your forum has been really valuable so far, thankyou for sharing :blush: . I hope I can contribute with a project I want to start soon.
I’m about to do a couple of mycelium material grows and wanted to run my plan by you for any expert tips!
I hope to make as best a “mushroom skin” as I can, using the little equipment/materials I have access to.

So here it goes:

  • Two species in mind: a pleurotus sp. and G.Lucidum (I have the option to also test trametes versicolour, but I have read that it is very hard and tough…) - preferably just 1 species, which would be reishi
  • Substrate: hardwood sawdust in bags
    -> Once bags are colonised, I crumble (or blend?? - maybe to risky?) the mycelium into thin trays and cover for recolonisation. I assume this is a crucial part to improve “skin-like” properties via additives. Preferably 5 trays (same species/substrate), one control, 4 different additives. Thickness of tray ~1cm (as I hope to heat press end results to ~1-2mm).
    ==> Additives to the tray (at what stage(s)?): PEG equivalent (eg natural emolients shea/cocoa butter) and/or glucose sprayed on with water mix (light spray every day for a thin layer of moisture??), boiled used latex gloves or plastic bags (chopping up etc…)
    ==> Any other ideas for accessible additives that I should try to increase elasticity? Waste cotton from local elastic textiles is also an option, such as used stockings or underwear lining.
  • Once the tray is colonised into a thin mycelium layer, I will try a a couple of post-treatments such as: 1) a 48hour soak in glycerin then a low temp bake 2) a heat press
  • If there are noticeable leather/skin-like properties at this stage I’d be happy :smiley: , and if so, I would like to try some further coatings, such as oils, and also flexural and tensile tests to get as thin and skin-like as possible and get results.

Anyways!
Any advice would be so helpful!

Peace out mushies,
Pete

Hi @MycoPete. Your protocol looks promising and I see a lot of knowledge I’ve read elsewhere on the forum come back. I’ve got to add that it goes beyond my own knowledge though. It seems right up the alley of @Gammarra and Simon, a colleague of @Elise

I also remember that Kristel Peeters did some experiments with a range of coatings at some point. She’s not on the forum (yet). I’ll refer this thread to her, let’s hope she wants to share some of her experiences :slight_smile:

well I do wonder if any source of gelatin in the substrate would improve the overall protein content, shrimp skins adn the like should increase your protein ration and elasticity


#4

Hmmm. Gelatin would be interesting - maybe some micro-additions/droplets during the tray recolonisation rather than before the initial bag colonisation?

I am very interested in the shrimp skin additions! @Gammarra, you mentioned they increase elasticity - is there research behind this or is it chemically true? If so, what about other waste meat skeletal products like chicken leg cartilage :smiley:

well the whole idea is that most of this mushrooms are also producen chitosan much like the shrimps so having it already available, might help.

I checked sci-hub and google scholar, and the research is undecided, seem slike chitosan solutions inhibit fungal growth in undesrided mushrooms so no idea, which way it will go
