Default run variant

The default run variant, if you don't pass any options, just has the minimal growth conditions set. What this means can be seen at condition.

Notably, this implies a growth medium that includes glucose and salt. It also includes oxygen, which is not strictly required, but greatly benefits cell growth, and is of course easier to have than not have as it is part of the atmosphere!

But the medium does not include amino acids, which the bacteria will have to produce by itself.
