Milk in substrate

Has anyone tried milk in their jars? I've heard of milk agar. I imagine if this did encourage bacteria it would be beneficial bacteria. Ones which produce H2O2, ethanol. It could simulate cowdung. As many bacterial species found in their milk can also be found in their dung. The addition of citric acid would help to stabilize the casein in the milk. Citric acid would also drop the pH down to 2-3.2. Well below the pH in which most undesirable bacteria thrive. It would promote Malolactic fermentation like with wine. The milk wouldn't produce a strong sour smell because the lactic acid is being used for the organism's energy cycles. Most bacteria in milk are obligate anaerobes anyway. The milk would add enzymes, nutrients, fats, and different proteins. So what do you all think?

Isn't milk also slightly acidic?

Also consider unpasteurized milk--for the real batch of bacteria!

From using milk agar in microbiology I think that i remember that it was just for certain strains of bacteria. I don't think that it would be beneficial for mushroom production. It would probably just help different types of contaminants that you don't want set up shop.

I asked the same question some time back and they answered that it will be sure to contaminate. I haven't tried it, though. The safe bet would be to soak in milk before pc-ing, like in coffee. But what will happen to the milk in the grains during the PC process I don't know.

UPDATE!
The jar contamed but I tranfered it to a casing and put it outdoors. I planted some rice on top of it. Strangely enough the half colonized jar didn't smell, at least it doesn't smell like sour milk. Bacillus & Lactobacillus compete. Lactobacillus produces bacteriocin which kills other microbes.

I think this idea deserves further study. I know people who harvest wild sheeps head (maitake) mushrooms, and they swear by dumping milk on the mushroom. Supposedly, it makes the mushroom grow a lot within twenty four hours. I did some searching on the subject, and all I could find were references to milk dunking. I didn't find info (outside of your one test referenced in this thread) regarding milk as a substrate material.
It would also be interesting to know the effect of other sources of substrate moisture. What about blending a few ounces of cow manure in a quart of water to use in BRF cakes?
