Within the last 10 years, deep-sea hydrothermal vents of                   the Galapagos Rift, Guaymas Basin and other sites have been                     discovered to contain densely populated, metabolically active                   animal communities.  These communities, living in permanent                     darkness and having a high degree of spatial isolation from                     similar communities, base their food chains largely on                          lithoautotrophic bacteria rather than on products transported                   from the photic zone.  Lithoautotrophic bacteria are those                      which oxidize reduced inorganic compounds (e.g. hydrogen                        sulfide) to generate useful energy.  They produce organic                       compounds from the precursor carbon dioxide and occur at the                    vents principally as symbionts within tissues of worms, clams                   and mussels.  To date none of these symbionts has been                          cultured apart from the host organism.  These investigations                    will (1) test numerous approaches for cultivation of the                        symbiont of the Galapagos vent mussel, (2) clam species, (3)                    complete purification of the bacterial DNA from numerous                        individual tube worms (Riftia pachyptila) from widely                           seperated vent sites.  By using the method of DNA:DNA                           hybridization the fine-scale evolutionary relationships                         between these currently very disjunct populations will be                       defined.
