I just did a very brief research in my documentary on "halophiles"
and picked out entries dealing with methane formation and
anaerobes:

************************************************************
If anybody is interested, I know Mah, Zhilina, Stackebrandt and
Gunsalus personally and could ask what they think about biogas and
salinity.
P.S.: I am more often (or less seldom, to be more precise) in
BITNET than in COM. My network-address is "IBT006 at DJUKFA11"
