Pleurotus Ostreatus on animal litter spawn

Preparing the substrate for spawn

  • 150g of animal litter (natural, organic, compressed wood)
  • 300g of water
  • One spoon of starch (potato or manioca)
  • 4% of ecologic honey (cane sugar or molasses is also fine)

Dilute the honey and starch into the water, then add it to the wooden bits. Soak the wood litter in water for a while. When the wood is fully absorbed, it doesn’t have to show extra water on the ground, nor dried parts either. Leave it rest for sometime.

Steam sterilize the jar

Put the wooden bits with all the ingredients in a jar (the lid of the jar must have an air filter, see previous articles on how to do it).

In a pot, put some water on the ground, then keep the jar lifted up with some metal structure. turn on the fire and when the water boils, keep the jar to steam-sterilize for about one hour.

Inoculation

The procedure is the same as explained in previous articles: with all the environment clean and the tools sterilized, cut open a piece of Pleurotus Ostreatus mushroom and put some pieces of the internal side of it in to the jar.

Close the lid and keep the jars at about 23 degrees Celsius for a bunch of weeks.

Your jar will be fully colonized when you see the white mycelium running all over it.

Now you have a full jar of spawn ready for the inoculation of your final chosen substrate to grow the mushrooms on.

Enjoy!

Homemade bread in electrical oven

This recipe is for about 1Kg of white bread. Once you have some experience with the procedure, you can experiment with other flours and procedures as well. The important thing in my experience is to know about your oven, in order to use it properly for an amazing home-made bread experience 🙂

Activate the yeast

  • 600ml of water at 25 Celsius degrees
  • 12.5g fresh yeast (break it in small pieces)
  • one teaspoon of white sugar
  • one teaspoon of white wheat flour

Stir well and let the mixture rest for about 20 minutes: when you see a thin layer of foam on top of the water the yeast is activated. If the foam doesn’t form, don’t worry: your yeast will be kicking out inside the flour on the next phase anyway.

Knead the dough

  • 1Kg of white flour
  • one teaspoon of salt
  • one tablespoon of extra virgin olive oil
  • spices: a bit of rosemary or oregano and some sesame seeds (here you can experiment with lot of different combination of spices and seeds!). You can mix spices and seeds if you want: this will give more flavor to your bread.

Two Medicinal Mushrooms: Fomitopsis Betulina and Fomitopsis Pinicola

Fomitopsis Betulina (Birch Polypore)

An amazing medicinal mushrooms that likes to grow on birch trees. This plant has been used for thousands of years (a lump was found in a medicine pouch when they discovered the almost 6000 year old body Ötzi the Ice Man some years ago!).

It act as an immune tonic, anti-inflammatory, anti-tumor, anti-parasitic, laxative, anti-septic, anti-viral and anti-bacterial. Studies have indicated that the Birch Polypore acts as an aromatase inhibitor, meaning it helps to prevent the conversion of androgen hormones into estrogen. This is important in both men and women as high estrogen levels are linked to many hormonal imbalances and cancers.

Fomitopsis Pinicola (Red Belted Conk)

Fomitopsis Pinicola is a widespread wood-eating medicinal mushroom who goes by the common names Red-belted Conk and Red-banded Polypore. This species often grows on dead or dying conifers, but can also consume various hardwoods. Red-banded Polypore has a cream-colored pore surface, from which reproductive spores are released. This tough polypore is perennial, often persisting for years. Though not well known as a medicinal, Greg Marley writes that decoctions and tinctures made from this tree mushroom are anti-inflammatory and immune system supporting.

From a research dated 31st January 2020: “The compounds that are present in the fruiting bodies of F.pinicola included many useful enzymes, steroids, triterpenes and triterpenes derivatives, anti-tumor active constituents, and health beneficial nutritious compounds. These principal compounds showed important medicinal effects on the human body by providing a shield effect to the internal organs against diseases and also heal the damaged tissues and organs. The pharmacological effects of F.pinicola active constituents include anti-tumor, anti-diabetic, anti-hyperlipidemic by controlling obesity, anti-oxidant effect, anti-microbial and anti-inflammatory properties”.

Substrates for Pleurotus Ostreatus

Pleurotus Ostreatus (but other types of Pleurotus family as well) will grow on almost any ligno-cellulosic material.

A short list of products could be: straw, corn cobs, sawdust, cork, banana leaves, cotton seed hulls, newspaper, cardboard, toilet paper rolls, coffee pulp, sawdust, cocoa, peanut and coconut shells, cotton seed hulls, Jamaica, cassava peels, cotton, sorghum, corn stalks, grass, clover, wood, wastes of rice, wheat, cotton from textile industry, corncobs, crushed bagasse and molasses from sugar industry, water hyacinth, water lily, bean, wheat straw, leaves, oil-palm fiber, paper and paddy.
