In my understanding bacteria is a simple thing to grow as it requires: a Nutrition concentration at the right Temperature with the right Gaseous concentration at the right pH with additional Ions and salt suspended in water.
So one can have a vat with some disturbing/mixing mechanism and just have your bacteria grow in a specially formulated growth medium. This is simpler than managing something like algae that requires sunlight to photosynthesize.
Bacteria can duplicate at a rate as fast as every 10 minutes at a exponential rate this can generate a lot of biomass.
Bacteria has a cell wall consisting of a sugar protein called Peptidoglycan and coupled with the small volumes of bio-materials and gas volumes that bacteriums develop could potentially be sufficient to sustain a human as far as I understand it.
Now my question is: Is it possible to sustain a human as they exist today by growing bacteria in a vat, draining the growth medium, "sterilizing" the bacteria by sonic pressure or something like microwaving the contents of the vat, then eating/drinking the goop/sludge that is left which should exist of biomass that is human digestible.
I know that there are algae "pills" made from compressed algae that allows a human to generate ATP without the consumption of carbohydrates, so I'm trying to figure out if the same is possible with bacteria biomass.
Apologies if there are any problems with my post, first post. Didn't have enough rep to post in the meta sandbox.
