...P. R. Girguis; J. J. Childress; J. K. Freytag; K. Klose; R. Stuber SUMMARY Intracellular symbiosis requires that the host satisfy the symbiont's metabolic requirements, including the elimination of waste products. The hydrothermal vent tubeworm Riftia pachyptila and the hydrocarbon seep worm...

... for this process appears to be the absence of oxygen. Anaerobic sulfide production is widespread among different thiotrophic symbioses from vent and non-vent sites ( Riftia pachyptila, Calyptogena magnifica, Bathymodiolus thermophilus, Lucinoma aequizonata and Calyptogena elongata ). The extent of H 2 S generation...

...) of the hydrothermal vent tubeworm Riftia pachyptila to acquire a general overview of nitrogen metabolism in this symbiotic organism. There were striking differences between the symbiont-containing trophosome tissue and other host tissues. High concentrations of ammonia, creatinine and, in particular, urate were found...

...Shana K. Goffredi; James J. Childress; Nicole T. Desaulniers; Francois H. Lallier ABSTRACT Deep-sea hydrothermal vents are home to a variety of invertebrate species, many of which host chemosynthetic bacteria in unusual symbiotic arrangements. The vent tubeworm Riftia pachyptila (Vestimentifera...

...Shana K. Goffredi; James J. Childress; Nicole T. Desaulniers; Raymond W. Lee; Francois H. Lallier; Doug Hammond ABSTRACT Riftia pachyptila is the most conspicuous organism living at deep sea hydrothermal vents along the East Pacific Rise. To support its large size and high growth rates...

...Alissa J. Arp; James J. Childress; Russell D. Vetter ABSTRACT The sulphide-binding protein that occurs in high concentrations in the vascular blood and coelomic fluid of the hydrothermal vent tube-worm Riftia pachyptila Jones is the haemoglobin. Sulphide binding does not occur at the oxygen-binding...
