       | Barely discussed in the paper: bubbles.

       | Many fermentation processes produce gas, and some aerobic
       | fermentation processes happen while fully exposed to the air.
       | Gravity provides quite a bit of assistance separating gas bubbles
       | from solids and liquids.
       | 
       | In space, how do you build a fermentation airlock? With a
       | centrifuge? Can you safely punch down dough? How do you open a
       | sealed, pressurized container of anything carbonated? Can you
       | easily remove enough dissolved CO2 from your kimchi so that
       | eating it won't make you burp?

         | 
         | why you need a airlock? just burb regularly by opening the can.
         | you can also press the miso towards the bottom with some spring
         | mechanism attached to the lid

         | Yes, and for lots of anaerobic processes like lactofermenting
         | veggies, you would need some way to keep the pickles in the
         | brine (without just being able to put a weight on them), maybe
         | a sort of inner lid with some holes.
