Question About Coir

I'm just wondering does coir have any of the good bacteria or enzymes like poo does, because i know with a lot of bulk grows ppl use coir and most times they are to big to mix up in a glove box. So im just wondering why coir doesn't contaminate when working open air but if you tried the same thing with brown rice flower your shit would end up looking like a lucky charms commercial.

because we use our coir as a bulk substrate which is then pasteurized... this knocks out most other fungal contaminates and significantly reduces the numbers (and types) of bacterial contaminates that survive.

Yes i understand that we pasteurize it, but im saying if you did the same thing with brown rice it would contaminate. Each time ive used brown rice ive pressure cooked it first. Or maybe im wrong and ive just had bad luck with brown rice and there is no real difference.

are you sure you understand the difference between sterilize and pasteurize? cuz there is a big difference my friend. and poo doesn't have "good bacteria or enzymes" as far as i know. pasteurizing kills the bad germs and leaves the good, sterilizing wipes out everything.

Ultimately, I think he's asking if the actinomycetes (firefang) / "beneficial bacteria" would be present in coir...but the question get's trickier after that because he then mentions brown rice in conjunction.
Actinomycetes - by the way - are the thermophillic bacteria that do a great deal of the work of breaking down material in hot/"active" composting. The center of compost piles routinely heat up to about 140-160(F) and it's these guys who do it.
The answer is that neither coir or brown rice will contain very many of those microbes, if any at all. You'll find them in poo and compost because they live in the soil and have the opportunity to colonize "outdoor" substrates in the wild so to speak.
--- I think the bottom line answer to the question of why coco-coir doesn't contaminate like brown rice flour does is...
brown rice flour is a bountiful food-source for thousands of various microbes where as coco-coir is a little harder to digest. I'm seriously watering that down but fundamentally it boils down to that. Less potential consumers, less contaminations.
However, I think the real answer lies in the over all differences in the practices and procedures in which they're used. Brown rice flour is almost always used "uncased" which is more contaminate prone in general. Coir is generally cased with something else - peat/verm mix, frx. - that probably had some lime added to make the pH of the peat/verm mix even less hospitable for tender new colonies of contaminates to form. Uncased coir can contaminate pretty damn fast...
Hope that helps...

After I post this I'm going to go look it up, but if I remember correctly, coir has lignin (sp?) in it, which strengthens certain cell walls and makes it more difficult for microbes to pass through or contaminate the coir fibers. More difficult, but not impossible.
Ok, I looked it up, and I think that's correct. There's also something in here about ion exchanges, but that only means coir is protected against a marked change in acidity (coir's a very weak acid, pretty close to neutral), so I don't think that has anything to do with it.
Anyone wanna jump in here?

He's confusing grain spawn with bulk substrates. Brown rice, rye, wbs, etc., are grain spawns and must be sterilized. Manure, coir, straw, compost, etc., are bulk substrates that need to be pasteurized, then spawned with colonized grains. RR
