Anaerobic life has proven ubiquitous, indeed, so wherever conditions
are right-- a biogas digester, a stagnant pond, one's own gut--
anaerobes indeed "show up". One may want to gather inoculates from
various sources-- cow manure, ground up termites-- and put those
things in the digester, but it is not certain that will assist in
producing more biogas. Regardless, given that the digester will be a
very complex ecosystem exposed to repeated inoculations with
incoming material, there is little point in trying to arrange things
so that the "livestock" are restricted to a particular set of chosen
species. It might be done, but it would require sterilizing incoming
material, etc., and it's not clear all that can take place and still
have the system be net positive for energy, or indeed anything like
as net positive as a "fill and forget" system.<br>
