From what I've read, when you grow oyster mushrooms you can either sterilize or pasteurize the substrate, and pasteurization is supposed to be better because it preserves micro organisms that help reduce contaminants. Recommendations for pasteurization seem to require heating for a long time, why is this - don't things die quickly in heat ?
Heat Treatment Equipment Autoclaves. Grain substrates that are used in the production of spawn typically require sterilization. Some mushrooms, like shiitake, are often not aggressive enough to compete with other fungi.
About Autoclaves. Autoclaves are simply chambers that can contain pressurized steam in a controlled manner. Large ones, like those we offer, are used by mushroom growers to sterilize substrate for those species, like shiitake, that require it.

So what kind of substrates are pasteurized? One perfect examples is non-supplemented straw, a mushroom substrate which is nutritious enough for the mushrooms to grow, but not so rich in nutrients that it needs to be fully sterilized.
Jan 23, 2018 · For those that use wheat straw as the main substrate, the pasteurization process can be used to prepare the substrate for the mushroom. Pasteurization does not sterilize the substrate but will remove the unwanted contaminants and retain the beneficial bacteria. This process is the easier and faster of the two but will consume more water.

easy it is to properly pasteurize a substrate. This is the method that I use to prepare pasteurized coir/coffee substrates for my edible and medicinal experiments, but it can easily be adapted to just coir/verm, horse/cow manure, or whatever your substrate mix of choice is. I got my methods from watching how a few other members go about preparing
Seal things up so that nothing else can get in there, and put your future mushrooms in a warm dark place – a stable temperature of about 24ºC (75ºF) is best for most species. After a few weeks (or months, depending on your spawn-to-substrate ratio and mushroom variety) – your creations should be ready to fruit!
Jun 17, 2013 · in the mono tub bulk substrate post it says to pressure cook your verm, coir, horse poo substrate, is there a reason that its not being pasteurized?
Sterilization kills everything. Pasteurizing leaves some beneficial things behind that somehow protect the substrate from contamination. Sterilized substrates must be kept sterile, ie filtered jars or spawn bags Pasteurized substrates can be placed in less than ideal open air conditions without contaminating while the substrate is eaten up by the spawn.

The problem with a double boiler is that the steam is going to heat your substrate up too fast. I've tried similar methods with similar results- it always goes over temp for me and I end up with partially sterilized subs which contam quickly. The glass on the jars acts as an insulator for the heat, spreading it evenly through your substrate.

In this method pre-wetted straw is packed in wooden trays or boxes and then kept in a pasteurization room at 60-80C for few hours. Temperature of the pasteurization room is manipulated with the help of steam through a boiler. Substrate after cooling at room temperature is seeded with spawn.
Why pasteurize mushroom substrate? Why should you pasteurize bulk substrate for mushroom cultivation? Pasteurization is a process that has been used for hundreds of years to destroy harmful germs in food. It is commonly known for its role in milk and juice production and was invented by the French chemist and microbiologist Louis Pasteur in 1864.
"Isn’t there another way to pasteurize large amounts of straw?" Yes! It’s called Cold Water Lime Pasteurization, and it’s a cheap and effective low-tech way to prepare substrates for growing mushrooms. The process is simple.
