 Detergent bath method of pasturization

Coming up soon I will be innoculating some starw logs with oyster spawn. I read of the detergent bath method outlined in GGMM and I'm gonna give it a shot. Was just interested to hear others opinions on this method- have you tried it? Does it work for you? I will be growing pink and yellow's outdoors. Stamets also says that in southeast asia quite often cultivators of pink oysters dont pasturize at all! So I think with the detergent bath method the spawn should do just fine and have a big enough window of opportunity to get a good stonghold on the substrate. Thoughts or ideas?
Thanks

I've been trialling "Aware" clothes washing powder, and it works a treat. It contains plant based surfactants, zeolite, citrate salt, cellulose colloids and washing soda from salt and limestone.
So far I've used it on Pleurotus eryngii and pulmonarius. I soak my woodchips in it, and have also soaked wheat grain in it (prior to heating). The mycelium seem to appreciate the extra food content.
My clothes washer can wash at at temps up to 95 degrees Celsius (or is it Centigrade?), at any rate-close to boiling. So I've been using the grey water from my washing to 'treat/condition' a BIG pile of woodchips.

I am just about to try a straw log with only the soap soak as well. I have a couple normal heat pasteurized things on the go and have some extra jars so thought I would try a straw log with only the soap soak and see how it goes because my wife hates when I pasteurize straw in the kitchen  I remember reading a post here months ago where thats all someone did and it was successful.

cool, very interesting! i'm going to try it using one of the 'dr. bronners' soaps. they are all bio-degradable and earth friendly. i'll let you guys know how it go's!
do you think the water should be hot to begin with? or just a cold water soapy soak?
i think this method has a lot of potential, if it works out it'll be my method choice
worowa- thats cool you utilize your grey water! we do too- we dont have a washing machine though. but all our sink water goes out to some fruit trees
thanks guys!

I'd like to be able to use my grey water, but I have a creek running through my property that feeds into a salmon and steelhead stream. Thus, it all goes into the septic system. I could probably intercept it for use and then dump down the toilet after pasteurization, but. . .

PS. That reminds me. Somebody should do a dirty laundry grow. It would be a hoot to see oysters fruiting from old underwear, t-shirts and torn bluejeans. Cotton actually makes a pretty good substrate.

yeah a dirty laundry grow would be pretty cool!
well maybe one day if you get a chance you can utilize some grey water, cuts down on water usage a lot thats for sure! we dont even have septic. composting and grey water.

Hey, paddy straw mushrooms grown on cotton waste are much more productive than those grown on straw. I would imagine shredded cotton clothing would be good for that as well.
Check this out -- http://fungus.org.uk/nwfg/volv.htm
I would imagine charities like Goodwill take in a lot of old cotton clothing that isn't in good shape to sell. Maybe they'd let you dumpster dive.

I grow oysters on shredded washed wheat straw. The soap I use is Seventh Generation hand dish washing soap.

I used the Down East dish washing soap. Environmentally friendly, contains sodium carbonate and synthetic surfactants (whatever those are), but no phosphates, petroleum, dyes, scents, acids, caustics, etc.
We shall see how it goes.
My kid is always outgrowing clothes with large stains/holes that prevent us from passing on to other kids, so maybe I will start hording anything cotton for a future grow.

Don't wash the clothes! All of those baby formula and ketchup stains are a potential source of nutrition for growing mycelium! Sweat stains provide valuable micronutrients!
Okay, maybe not.
The illustrations of cotton waste from that site look like unspun cotton fluff. I wonder if there's an easy way to reduce a pair of blue jeans to something similar without trying to shred it with kitchen shears. More surface area for mycelium to cling to=faster colonization, right? A wood chipper might work, but think threads could get tangled around the chewing gear things, like the beater brush on an upright vacuum cleaner.
The article mentions that cotton waste is partially composted. Maybe composting shredded cloth with used tea leaves? Coffee grounds? Do they do similar things in bulk substrates?
I'm only just getting started with this as a hobby, and I already have a half dozen projects going!
Still. Paddy straw mushrooms are quite tasty. I've never had them fresh, but my mother got ahold of some fresh ones a few years back and went on and on about how great they were...
I'm going to check some of the bigger, fancier asian grocery stores after work. If the cultures themselves can't survive refridgeration, can tissue from a chilled mushroom be cloned? I don't have a laminar flow hood, so I will probably have to go the peroxide route. I will report the findings of my expedition later...

Just thought I would update. My oyster straw log is looking good after just a straight detergent bath.
No sign of contams at 12 days from creation of the straw log.
I did use hot water from the tap when I did this, plus I think a plastic bag is a pretty clean growing environment. I am tempting fate with a second batch now. Only cold water out of the garden house, made in the yard, using mesh bags of various types.
Might as well push the limit.

thanks for updating, looks good! push the limit
let us know how it go's and I'll do the same! come this Monday I'll be innoculating several straw logs (logs made with chicken wire, will be incubating indoors and fruiting outdoors). some will be derergent method and some lime bath
aaaaaaalmost done on my outdoor grow hut and im real happy with it! i'll post some pics in a new thread later on.

That looks fantastic culland. Nice work!! I think we should all do a dirty laudry grow and compare the results. I think that is a good idea. Anyone up for it?

Really you could just throw the dirty laundry in let it cycle on wash cycle then remove, inoculate. Right? Thats what I was thinking.

Yea I suppose if you are inoculating the clothes, I was thinking more on the lines of worowa's post above about using his hot grey water to treat piles of woodchips.

Well lesson learned in my cold water detergent bath attempt. Hot water helps your straw dry immensely and if you are going to use cold water, you gotta drain/dry a lot longer.
I had a better drying setup then normal and I let it dry the same amount, it even felt about the same putting it in the bag, but I could tell within a day that they were to wet. The sweat smell of wet straw is pretty strong when I look at them, even after almost 10 days.
Neither bag has visibly contaminated nor is there a musty smell and the mycellium is showing in various parts, but you can tell its struggling. After 11 days it should be a lot further along then it is.
Think I will abort the attempts and try again my next batch of grain spawn, this time with more care in the drying department.
