From what I've read you should be pasteurizing, not sterilizing.

I'm curious how you'd go about sterilizing a freshly dunked casing layer without killing the whole enchilada. RR

Depends how you stored it. If you sterilized it in a sealed or ported oven/myco bag then it should be fine. There's no reason to resterilize. If you sterilized it right the first time and it's stored properly then it would be pointless to resterilize it.

To be honest i've never pasteurized, i sterilize everything, and from what i understand the only things i'm losing are nutrients and i have never had a problem or anyone else for that matter noticing a potency loss

If you sterilize a bulk substrate like poo you get a higher rate of contaminations (unless the poo is being colonized in a jar or bag)
Sterilizing is for spawn, cakes and casing material. Pasteurization is better for bulk subs.

So Nibin,
Adding poo to perhaps a large brf jar and sterilizing it would yield better results than straight brf pf tek style? Thanks.

No. Gram per gram BRF is more nutritive than Hpoo.
We use Hpoo not because of it's especially high nutritional content (all grains are more nutritive) but because of other properties, such as great water retention, good balance of nutrients, facility of preparing big amounts of it, texture, etc.
Think about it this way. Look at the yields that come from a tub and compare it to cakes.
Say you get 2000gr wet out of 2 gallons of substrate in a monotub. 2 gallons is 32 half pints and out of 32 half pints, at 100gr wet per cake you would be getting 3200gr.
But then againn, 32 cakes will take up more space than a 2 gallon monotub.

As far as sterilizing and contam how do you figure that sterilizing would be more chance of contam, i contam very very rarely, and the only benefit i could see is if there were some kind of bacteria still alive that mushies thrive on and the bad bacteria contam gets beat by. I would love to hear a reply to this.

I've been pasteurizing my 50/50 casing mix as per RR's instructions. Should I be sterilizing this instead? or is 50/50 a casing material you pasteurize?

There are microorganisims that help ward off contaminants in the casing layer. That's why its a good idea to pasturize, not serilize your casing.

I always followed the instructions on the 50/50 manual and that recommends sterilization.
But RR has been recommending pasteurization also for casing layers lately so now I'm confused... 
Anyway, the tek is old and RR is up to date so I'd go with RR.

Sterilization always worked well for me.
I don't doubt that benefits can be obtained from proper pasteurization, but adding a new technique that you may or may not get right might not be in your best interest.
There's no point in resterilizing something if you did it properly in the first place. It also makes no sense to sterilize something and then pasturize it.

Same here. Sterilization always worked for me. I'll have to give pasteurization a go sometime.

I use pasteurization for verm and coir because it seems clean to me and I'm lazy. But Thats all I use for sub and caseing.
