There are so many ways to skin this cat…
my biggest concern is what are we doing with all the skin and bones? (spent biomass & sticks.).
I’ve said it before, I’ll say it again. I want to make my extraction solvent with it. via cellulosic ethanol production. @Shadownaught has enzymes that might enable that (in case someone else wants to try).
Fungi are the correct answer, whether selected or engineered, or even just as a source of the enzymology. introducing a half dozen novel genes into a hi-test Belgian yeast to enable hemp cellulose as a carbon source and 17-20% starting wash would not be that difficult these days. we’ve had those strains tamed for awhile.
