The means of inoculating shiitake mushrooms on logs is comparatively easy. The key to success is to make it possible for the logs are heat and moist.
Logs may be soaked in liquid spawn or sawdust. The alternative of the kind of medium is determined by the tree species and climate situations. Generally, the commonest methodology is utilizing sawdust.
Liquid spawn inoculation will increase elevation by as a lot as 13 %. However, it takes longer to colonize.
During inoculation, the mycelium will launch carbon dioxide. This encourages stronger progress. As a outcome, the yield will enhance.
The progress of the mycelium is determined by the quantity of moisture within the log. When the mycelium is colonized, it is going to start to develop white at both finish.
Shiitake mushrooms may be harvested for as much as three years. They are thought-about to be a gourmet mushroom due to their dense meaty style. There are a lot of strains out there, so experiment with totally different varieties.
Depending on the kind of pressure, the inoculation procedure will take about four months to produce mushrooms. A grower might wish to experiment with totally different strains to find out which is finest for his or her farm.
Before inoculating a log, the bark have to be clean. Cracks within the bark enable moisture to flee, and reduce the speed of profitable inoculation.
Usually, the very best time to reap is within the early spring. Trees ought to be felled earlier than the bud swells. If the timber are felled in the course of the summer season, they need to be stored cool.
Transferring to agar
Liquid culture of shiitake was examined utilizing varied mediums. One of the mediums is a liquid spawn inoculated on sawdust media. This methodology was discovered to extend the elevation of shiitake in comparison with typical tradition. It additionally confirmed a rise in yield.
The finest medium to make use of is a medium that has a pH worth of a minimum of 5.3. Mohamed liquid medium has a pH of 5.3 and incorporates 2.5g of yeast extract, 0.5g of CaCl2 2 * 2H 2 O, and 1.0g of FeSO 4 * 6H 2 O.
The medium to make use of for liquid culture is chosen in accordance with the expansion price and section of the pressure. Agar is a standard alternative, nevertheless it ought to be sealed and sterile.
The agar ought to be capable to stand up to strain cooker temperatures. Also, agar may be purchased with antibiotics added. Using agar from mushroom supplies is prone to be pre-mixed with vitamins.
Yeasts may be preserved by lyophilization. They will also be preserved by freeze-drying. When rehydrated, they are often transferred to 5-6 mL of broth medium.
For a extra economical means, you should purchase premixed agar with antibiotics from Fungi Perfecti. Premixed agar is costlier than selfmade agar, however it’s straightforward to make use of.
If you wish to grow a culture of mushrooms, the simplest methodology is to switch it to agar. You can do that with a syringe or through the use of an inoculation loop. However, there’s a danger of contamination. There are some indicators of contamination, comparable to a inexperienced color scum on the highest of the tradition.
After a interval of progress, you need to depend the variety of colonies. Best outcomes are obtained with a colony depend of 25-250.
Sterilization of a syringe needle

Some industrial growers will use spore syringes. These are used when working with giant volumes of mycelium. They may cause a danger of contamination, particularly with smaller volumes. For a extra sanitary methodology, you’ll be able to insert the needle right into a jar of liquid tradition.
Liquid tradition may be saved within the fridge. After injecting mycelium, the needle ought to be pulled again and the mycelium ought to be pushed out of the needle. If the mycelium is caught collectively, you’ll have a tougher time pushing it out.
Inoculations utilizing lids with injection ports are normally achieved with a sterile approach. This may be achieved in a laminar stream hood, or a nonetheless air field.
Liquid tradition may be transferred to agar plates or grain jars. Alternatively, it may be used to inoculate a sterilised grain. Typically, the tradition will colonize the substrate quicker than spores.
If you’re a novice grower, it’s possible you’ll wish to put money into a sterile syringe. It is usually a stepping stone in your mushroom cultivation, and you’ll study new expertise alongside the best way.
Besides utilizing a sterile syringe, additionally, you will want a sterile atmosphere for the liquid tradition. To scale back the chance of contamination, it is very important disinfect the jar and the lid.
