[Digestion] Calculating methane production

[Duncan Martin]

Come on lads!!

I might speak only for myself but I think it's an abuse of a forum like this 
for folk to use it as a replacement for ten minutes work in a half-decent 
public library or on the internet. I'm more tolerant when the enquiry comes 
from somewhere remote. But I don't think the USA qualifies!

For info, Steve, yes there is a mass of research and "a particularly good 
methanogenic microbial community" is characterized by a great diversity of 
species, very many of which are not methanogens. Now, go read!

Fraternally yours
