In addition, one of the most exciting scientific discoveries of the past decade has been the discovery that microbial life exists in the subsurface at depths hitherto unanticipated--the so-called 'deep biosphere.' To date, studies of potential subsurface substrates necessary to support such deep microbial communities have focused largely on [H.sub.2]-based chemolithotrophy (5, 6).
Mallory and other researchers in Lechuguilla have discovered bacteria that, amazingly, oxidize minerals in a process called chemolithotrophy (which translates to eating of rocks).
