Heinz Wilkes, a leading biogeochemist at GeoForschungsZentrum Potsdam (GFZ), points out: "The bacteria isolated here for the first time from marine sediments use sulphate instead of oxygen for respiration and utilize propane and butane as their sole source of carbon and energy. These organisms are tough specialists that have become adapted to strictly utilising only these and no other substrates." [Quote Ends] I'm told that when sulfate is 'breathed' instead of oxygen the output is not carbon dioxide but a mixture of sulfides, like the really smelly hydrogen sulfide. Maybe we're nearer to a 'rational' explanation for all those sulfurous smells associated with close encounters? Some work has been done already - see http://www.nidsci.org/pdf/rullan.pdf Odors from UFOs Deducing Odorant Chemistry and Causation from Available Data A.F. Rullan, July 2000.
