Rice wash and mammal
milk are used to select for lactobacillus from the airborne microbiome in a given location.
Molasses and sugar are used to keep it viable, long term.
But neither rice or milk are universally available.
We know we can select for lactobacillus by adding salt and excluding air when we are pickling, and we know lactobacillus is endemic to some plants.
Cabbage in particular seems to be loaded with these beasties.
I made some cabbage based lactobacillus serum a while back, using coconut oil as the way to exclude air.
It seemed to work rather well, but I have difficulty growing cabbage.
Jerusalem Artichokes are easy to grow and they have that sweet inulin that lactobacillus seems to favor.
They also store in the ground, so they are available year round.
In the places they cannot grow, there are usually other high inulin
roots that grow even more easily.
I plan to cultivate lactobacillus in a barrel and
feed it a little of everything, with Jerusalem Artichokes as the
staple food.
Occasional additions of
dairy especially yogurts, with their own strains
should help keep the culture from losing dietary flexibility.
This will join my other mad ideas , like the
bucket of rotting citrus, and live in the
greenhouse over winter.
My only concern is the possibility of botulism in the submerged solids.
I lost one
chicken to what might have been botulism, and I'm not keen to have repeat.
The chooks get most of my compostables, but maybe I'll skip this.
Since the whole thing is similar to making silage, or traditional pickling ,I'll look into those practices to see if botulism is an issue.
