[Digestion] Calculating methane production

[finstein at envsci.rutgers.edu]

Duncan -

As you say (in effect): one man's junk (one microbe's metabolic waste) is
another man's treasure (another microbe's substrate). But questioning the
complexity of the metabolic web terminating in methane was not what
started the thread. Rather, the question asked was - how to estimate
methane production.
