Pastuerized Poo/straw life

I pastuerized some poo 2 days ago, left it covered in my shower to strain. Forgot to use it last night, was wondering if it would still be useable tonight or if i`d have to pastuerize it again?

Once it's properly pasturized and at the correct moisture content, you could put it into a large zip-lock bag and store it for months in ready-to-use condition. *EDIT* ?You haven't showered for over 2 days? PHEW! And I thought horse poo smelled!!

Hmmm, don?t think so. What you forget is that by pasteurizing alone many bacteria and some molds still survive. If you leave the pasteurized substrate uninoculated, it will "spoil" eventually.
But not after 2 days.

In reply to:

I think you mean not BEFORE 2 days. Probably not before 10 days at least.

Thanks gents. What I needed to know. More poo-straw to spawn puts a smile on my face. Hope the PUerto Ricans do better this time.

Probably much sooner. Read TMC, page 124 towards the bottom. Big letters.

I'll take your word for it. I always spawn it the day after pasturization anyway.

Here you have it:
Paul Stamets and J.S Chilton: The Mushroom Cultivator , page 124
Spawning Methods
Spawning methods, like spawn itself, have evolved over the years. As late as 1950 Agaricus brunnescens growers customarily planted walnut sized pieces of manure spawn or kernels of grain spawn in holes poked into the compost at regular intervals. Using this method spawn running was slow, and areas far from the inoculum were more susceptible to invasion by competitors. The full potential of grain spawn was not realized until the development of "mixed spawning". The principle of mixed spawning is the complete and thorough mixing of the grain kernels throughout the substrate. In this manner all parts of the substrate are equally inoculated, resulting in the most rapid and complete colonization possible.
The standard spawning rate used by Agaricus growers is seven liters/ton of compost or one quart/8 sq. ft. If spawn is readily available and cheap, it is advantageous to use high spawning rates which lead to more rapid colonization. It is also advantageous to break up the grain spawn into individual kernels the day before spawning. If the spawn is fresh, the grain should break apart easily. If the spawn can not be used when fresh, it should be refrigerated at 38?F.
The basic principle of spawn running is the same regardless of the type of mushroom or substrate. COLONIZATION MUST PROCEED AS RAPIDLY AS POSSIBLE TO PREVENT OTHER ORGANISMS FROM BECOMING ESTABLISHED. Once the mushroom mycelium becomes dominant, natural antibiotics secreted into the substrate inhibit competitors. To prevent invasion by competitors it is important that spawning take place under carefully controlled hygienic conditions. Fungus gnats in particular must be excluded, and for this purpose a tight, well sealed working area is best. This area and all tools should be disinfected one day prior to spawning with a 10% bleach solution. When using disinfectants be sure your skin is protected and avoid breathing any fumes.

Thanks Anno, but you know I've got the book. You didn't have to go through the trouble of scan/ocr, but I suppose it's a good post for those who don't have it.

Pasteurizing allows for the proliferation of beneficial bacteria which compete with unwanted contaminants.

Unfortunately, I'm not a microbiologist, so I will have to provide somewhat of a rudimentary answer. When material is pasteurized, the heat generated kills off bacteria that could compete with the mushrooms for food and even harm the mycellium. The remaining bacteria does not compete with the mycellium for food (or harm it for that matter) and can even make additional nutrients available.
Hope that clarifies things somewhat...

I heard from Road that if you re-pasteurize something, you are killing off that beneficial bacteria. Is there any truth to that? Not that I would ever doubt road, but I see ppl posting "Yea, I pasteurize'd it 3 times, let it sit for a week, and am going to pasteurize it again" (I am streching it a bit, but just to provide a example)

Sterilizing will certainly kill all the bacteria, but I wasn't aware that multiple pasteurizations would kill the organisms that were resistant to the temperatures pasteurization maintains. Maybe Roadkill will chime in and clarify this for us.

It`s not necessary to get Roadkill's advice. Come on. He knows what he`s talking about, YEs. But so do alot of us here as well. I`ve grown out enough bulk tubs to be able to give my 5c worth. I have re-pasteurised poo 3 times and the spawned it and it worked perfectly for me.

I am a studying microbiologist/chemist. I have not come into contact with detailed info reguarding the practice of pasteurisation. As I understand it, the more aggressive organisms tolerate natural conditions (normal temp ranges), while the organisms that tolerate higher temp conditions are not as aggressive...therefore pose a lesser threat to the mycelium of a standard species (P. cube).
I have personally found that p[asteurisation does not work for the micro-organisms in my area. I have had several consecutive pasteurisations go bad. When I sterilised my dung in a PC I found colonisation speed to increase and contamination to cease.
I have not examined this phenomenone in detail, but will continue to PC my dung.
I believe the idea behind pasteurisation is that beneficial organisms will remain that will either help to fight foreign contams or to induce fruiting in certain species. According to Stamets however, P. cubes do not require any bacteria or other organisms to induce healthy fruiting. I don't think that sterilising dung will decrease the successfull spawn run of P. cubes, but actually help in certain environments.
I am drunk and reached real far up my shizznit hole to provide the previous info. I am sure Anno will come along to correct me shortly (the dude is crazy smart).

I never said that! What I said was >> I would never sterilize horse poo! The reason I wouldn't sterilize it is this... you would lose some beneficial bacteria.
The purpose of pasteurization is to kill or neutralize all harmful organisms.
I have never had to re-pasteurize any poo... so I really don't know if it can be done. I always spawn my poo the day after pasteurizing it.

Very true Derrayld...and I don't have the answers to everything...I'm not an Expert!
In fact my motherboard went out on my computer....that is why I haven't posted in over 12 hours. Thank God a friend brought over his spare computer for me to borrow.
What would you do if I dissapeared for a week or longer? Answer : Ask others that know what they are talking about. There are lots....I repeat lots of people that know what they are talking about on this site.
I don't have the answers for everything! Hell...I don't think I'll ever have the answers to everything!! I read alot...and try to learn all that I can about mycology. Life is a learning experience.....learn all that you can! I still ask a few questions myself... and who do I ask...people like Anno, Joshua, Mushroom John...etc.
Joshua had a problem with pasturized poo and has been sterilizing his poo and hasn't had any problems. I'm sure he will go far in life....He has the ambition and drive!
So who truely knows what works best?
Do what works best for you!!!
