 Bare Necessitites for Oyster Mushroom Substrate

What are the absolute essentials for oyster mushroom substrate?
i am looking at starting an agriculture recycling project in which i will be using many different sources (plant) and trying to break them down as much as possible before turning them over to bacteria and insects.
my first experiments are with bamboo (as its weedy here and often a pain to dispose of).
am i right in assuming oysters can pretty much grow on any dead wood?
thanks for any input.

yes, oysters can grow on dead wood, paper products, leaves and twigs, even coffe grounds.

I have never heard of oysters growing on bamboo, on all sorts of other substrates. It would be very interesting to see if they will grow for you

i was thinking using those wood chopsticks, bamboo. they pack together fairly tight but have spaces (like super thick straw). any thoughts/suggestions for doing this? i hope to try many other substrates as well, in time.

You want materials that are high in cellulose and lignin, but low in nitrogen. Bamboo qualifies but it strikes me as being pretty dense! It should probably be chipped first, if you're using stalks.
As far as chopsticks go, are they used? If so they should probably be pasteurized at least! I'm really not sure. That could be begging for contamination.

Run your bamboo through a chipper/shredder or at the very least break/cut them into lengths ~1/2-1 inch in size. (same as dowels that are commonly used for log inoculations)

oh ok thanks! i will split them up  i dont have a chipper, and my wife will probably draw the line at grinding chopsticks in our blender.
are they used? my first experiments, no. if they are successful i plant on using this as a recycling method, which means i will be taking old (garbage) and trying to compost it (starting with fungus), so they will be used.
i plan on pasteurizing everything and using bags. fruit production isnt the main goal, breaking down the materials to eventual soil is the focus.
any thoughts on how something could be more effective in substrate break down rather than flush size....or are the 2 sort or related? ie more fungi fruits more substrate used (ie broken down).
other substrates, later one, will be left overs of: sugar cane, corn, rice and some kind of legume (Desmanthus?) used in crop rotation here.

Sugar cane bagasse is excellent from what I understand. Unprocessed canes are, naturally, high in sugar and are therefore unsuitable. Crushed corn cobs are good. Corn stalks are also a bit sugary and should be composted. Rice straw and rice hulls are good. I'm really unsure about legumes. If you're rotating crops you really should be tilling them into the soil.
The association between legumes and nitrogen-fixing bacteria is the only way (outside of lightning strikes) that atmospheric nitrogen can be made available to plants. I think companion planting with legumes would be a good idea! I may just try that.

thanks! i am taking excess waste from farmers, these products are not my own farm. i should say i plan to.
the sugar cane i use is already used and had the sugar extracted, so i think it is ok. i have seen a few sites talking about its use, especially in Asian countries. so i hope (actually a neighbour grows it on a smalls cale so i hoep to get some for trials.
right now i am soaking some bamboo (chopsticks) and will be sterilizing tomorrow in jars with a pc. this is just to check to see how things go, if it works i plan on using steam pasteurization and bags on a larger scale.
any tips on addition to the bamboo, or other wood, to make fruiting better? i see many farmers add various things to buffer ph, which i understand. but some others say they add corn to ADD nitrogen (to straw), where as it was posted above that low nitrogen is better....or is this just due to straw being too low?

The optimum ratio of carbon to nitrogen in a substrate for oysters should be ca. 40:1. Then, most of the substrate can be digested and transformed into mycelium and fruitbodies.
Some examples of C:N ratios:
alfalfa straw 15:1 - 25:1
coffee grounds 20:1
rice straw 50:1
corn straw 50:1 - 60:1
wheat straw 100:1
sawdust 500:1
paper 1000:1
Thats why people add bran to wood chips, apart from its carbohydrates.
But keep in mind that raising the nitrogen content raises the possibility of contams. To get started, I would recommend not to use additives, high on nitrogen.

One of the vendors at my local farmer's market sells yellow oysters on occasion, and he tells me they're grown on the same substrate used for Agaricus species--composted chicken manure. I'm currently testing out a mixture of wood chips and worm castings as an oyster substrate. I also just tossed a big sack of green chicken poop into the old compost tumbler along with a few shredded newspapers. It should be ready to use in a month or so.
