The first one an easy one for me :-)
Gorny, N., G. Wahl, A. Brune, and B. Schink. 1992. A strictly anaerobic nitrate-reducing 
bacterium growing with resorcinol and other aromatic compounds. Arch. Microbiol. 158: 
48-53.

Look in 'The Prokaryotes' 2nd edn. (Balows A et al., Ed.), Springer Verlag, 
New York, Heidelberg in the chapters on sulfate-reducing and methanogenic bacteria.
Most of them grow on H2/SO4-- or H2/CO2, respectively, in mineral media, so you only 
have to find species which do not need addition of acetate for their anabolisms (e.g., 
Methanobacterium thermoautotrophicum).

Aeckersberg F, Bak F, and Widdel F 1991. Anaerobic oxidation of saturated hydrocarbons 
to CO2 by a new type of sulfate-reducing bacterium. Arch. Microbiol. 156, 5--14

(oxidizes e.g. hexadecane!)

I hope this helped...
