[Gasification] Biogas from Pasture and second gen and GTL

[Mark Ludlow]

Maybe I'm confused also, but fermentation does not necessarily imply methane
production. It depends on the microbe. Methanogenic (familiar in ruminants)
bacteria produce CH4 and CO2; other fermentations (with Lactobacillus),
produce lactic acid; still other breakdowns produce ammonia if there are
amines such as proteins (i.e. chlorophylls) present.

There's no single cascade from living matter to simple molecules.

Now  I´m confused: 
What are we talking about, combustion (cigar, smoldering) or fermentation ( 
biogas) ?
