Organic Tree Oyster Mushroom - P. ostreatus - Mushroom Patch

Organic Tree Oyster Mushroom - Pleurotus ostreatus - Mushroom patch 

Synonyms: Oyster Mushroom, Hiratake, Tamogitake, Píng Gu, Sadafi, Chippikkoon
 

The Tree Oyster Mushroom is a flavoursome edible mushroom that is very easy to grow. The mycelium of this mushroom is extremely robust, which is why it is one of the most popular cultivated mushrooms. The fruiting bodies reach a diameter of 5 - 15 cm. The cap is grey-brown to purple, the colour changes to whitish towards the lamellae and the stem.
Pleurotus is rich in B-complex vitamins such as B1 (thiamine), B2 (riboflavin), B5 (niacin), B6 and B7 (biotin). It also contains folic acid and vitamins C and D (calciferol). A quarter of the dry matter of this mushroom consists of proteins and contains all the essential amino acids. Other important ingredients of Pleurotus are beta-glucans (polysaccharides), pleuran and lovastatin.

This fresh product is prepared fresh for you to order. The production time is around 3 - 6 weeks.
The mushroom spawn should be processed immediately after delivery.
If the product cannot be processed immediately, it can be stored in the refrigerator at 4 °C for up to 2 weeks.
We recommend that you plan for this when ordering..

 Suitable cultivation methods: 
straw bales, wood logs, mushroom patch for mycorestauration, spawn bags for indoor greenhouse    

Suitable substrates: straw, paper, coffee grounds, pulp of coffee beans, hardwood
Suitable woods:  poplar, oak, alder, aspen, maple, birch, ash, beech, willow, elm
Outdoors: this strain produces fruiting bodies in late summer and early autumn

You receive mushroom spawn already colonized by mycelium, based on organic raw materials (wood, rye bran from organic cultivation) in bags specifically designed for sterilisation.
Depending on the mushroom species, they are available in the following sizes:
1 autoclave bag with approx. 1 litre (500 grams) is suitable for propagation over 4 - 8 weeks in sterilised wood substrate (see mushroom patch instructions).
1 autoclave bag with approx. 6 litres of spawn is suitable for inoculating a mushroom patch of 80 x 80 cm.

Mycological restoration using a mushroom bed:
Some types of fungi are suitable for breaking down these toxins and removing them from the environment.
To do this, fungal mycelium from the relevant types of fungi is distributed in the contaminated soil and mixed with a suitable culture medium in order to cover a large area of the pollutant source. The mycelium strands grow through the soil. They absorb individual toxins directly or break them down into their components, rendering them harmless.
The fungus absorbs the toxins into its fruiting bodies. These must be harvested at the end of their life cycle and disposed of properly.
The areas of application for this type of fungus are
- Heavy metals cadmium and mercury,
- various chemical toxins such as benzo(a)pyrene, i.e. polycyclic aromatic hydrocarbons (PAHs), as they are produced in combustion processes, but also
- Dimethylmethylphosphonates (DMMP), which are contained in the chemical warfare agents VX, Soman and Sarin,
- Dioxin, also known as Seveso poison, which was used extensively as a weedkiller for a long time,
- polychlorinated biphenyls (PCBs), which are found in plasticisers, insecticides and additives,
- Trinitrotoluene (TNT) from military munitions such as bombs, grenades and mines,
- Bacteria such as Escherichia coli and other strains,
- petroleum products such as diesel and heavy fuel oil.
