Flax!

Read a research article titled: Conjugated linoleic acid inhibits hyphae formation in candida albicans.
They used conjugated LA from ground beef. Flax seed contains Alpha LA. They are different, but isomers, and have similar functional groups... i think.
Flax is getting popular as a substrate additive, but the word seems to be "best in small doses or else: stall"
I know that a polymorphic fungus like candida is way different from a basidiocarp, and Alpha linoleic acid is not exactly conjugated linoleic acid.... but I wonder.
How does flax perform as straight spawn? Flax is loaded with antifungal fatty acids. Why use it at all?
If the inhibitory effect has an affinity for competitor species and a minimal effect of the basidiocarps, then I would willing to give it a try.
Questions? Comments? Insults?... Gifts?

a while ago i could only find flax-straw (in small pieces), and if i remember correct the ostreatus didn't like it but the kings did. next time i'm planning to make a mix of straw, flax and beech sawdust & chips, reading that a diversity of substrates would be beneficial.
at the time i couldn't really find data on how it performed as a substrate, interesting to learn that it has natural fungicides.

In a "sort of" related topic, I remember inquiring about Spawnmate a while back and agar posted the patent information here:
http://www.shroomery.org/forums/showflat.php/Number/4102503#4102503
In the patent info whole flax seed was used as a supplement at casing or spawning and not as grain spawn, but it seemed to produce the best results of the seeds tested. I played with it a few times and seemed to notice slight increases in yields, but I didn't do any real scientific experimenting on it. I don't think it would do well as grain spawn due to the high oil content. Hydrating and sterilizing flax would likely be a messy ordeal IMO.

Foo, spawnmate patent is a loooong read. I eventually skimmed for a detailed description of the nutrient additives, then gave up. sorry and thanks.

Sorry about that! Skip over the rest of the jargon and scroll down to the bottom of that post to where it says "Table X". In that table it shows the yields in lbs/ft of grains, beans and seeds used in the tests.
Basically they would take flax seed, rape seed, etc and sterilize it in whole, dry form so that the seed would stay intact, but would kill the sprout inside. The seed would then be used as a supplement in a small amount at the time of spawning or casing. The idea is that these sterile oilseeds provide a delayed release of nutrients because the outer seeds would take a while for the mycelium to penetrate so that these nutrients are being fed to the mycelium while it is fruiting.
Of all the oil seeds used in the experiments, flax seed had the highest yields at 3.81lb/ft
