Sorry to sound like the famous Prof Joad (?) but what do you mean by a
large culture - and what is the purpose ? 10L of almost any medium you
care to name - if inoculated with only a few mg of soil will give you a
culture. After even a few hours, the culture content and balance will
be entirely dependent on the culture medium constituents plus a few
factors like temperature and aeration. In the early stages it will
probably be dominated by Pseudomonads, after a few days the Bacillus
species will loom large. Leave out any traces of organic matter, throw
in a little ammonium and some sulphur (sorry sulfur) and a little
ferrous iron and you can have a bevy of autotrophs. As it stands - your
question attracts the same answer as the question to the accountant "How
much profit did we make?" - answer "What would you like it to be ?"
So - "What would you like it to be ?"
Over and out.
