O-Proteobacterial diversity from a deep-sea hydrothermal vent on the Mid-Atlantic Ridge
The prokaryotic phylogenetic diversity was determined for a sample associated with an in situ growth chamber deployed for 5 days on a Mid-Atlantic Ridge hydrothermal vent (23322PN, 44357PW). The DNA was extracted from the sample and the 16S rDNA amplified by PCR. No Archaea were detected in the sample. Eighty-seven clones containing bacterial 16S rDNA inserts were selected. Based on restriction...
متن کامل(210)Po and (210)Pb in the tissues of the deep-sea hydrothermal vent mussel Bathymodiolus azoricus from the Menez Gwen field (Mid-Atlantic Ridge).
The hydrothermal deep-sea vent fauna is naturally exposed to a highly specific environment enriched in potentially toxic species such as sulfides, metals and natural radionuclides due to the convective seawater circulation inside the oceanic crust and its interaction with basaltic or ultramafic host rocks. However, data on radionuclides in biota from such environment are very limited. An invest...
متن کاملMicrobial diversity of a sulphide spire located in the Edmond deep-sea hydrothermal vent field on the Central Indian Ridge
A culture-independent molecular phylogenetic survey was carried out for a bacterial and archaeal community of a mineralized crust coating a sulphide spire, which was collected from the Edmond vent field (23 ° S, 69 ° E, 3300 m depth) on the Central Indian Ridge. Small-subunit rRNA genes (16S rDNA) were amplified from environmental DNA by PCR utilizing Bacteria-specific, and Archaea-specific 16S...
متن کاملEvidence for methylotrophic symbionts in a hydrothermal vent mussel (bivalvia: mytilidae) from the mid-atlantic ridge.
Symbioses between chemolithoautotrophic bacteria and the major macrofaunal species found at hydrothermal vents have been reported for numerous sites in the Pacific Ocean. We present microscopical and enzymatic evidence that methylotrophic bacteria occur as intracellular symbionts in a new species of mytilid mussel discovered at the Mid-Atlantic Ridge hydrothermal vents. Two distinct ultrastruct...
متن کاملA deep-sea hydrothermal vent community dominated by Stauromedusae
A dense population of stauromedusan scyphozoans (morphologically similar to previously described species within the genus Lucernaria) was encountered in a previously undocumented area of hydrothermal activity along the crest of the East Pacific Rise (Lat. 20 50.304'N; Long. 109 05.422'W; depth of 2605 m). A few galatheid {Munidopsis subsquamosa) and bythograeid {Bythograea thermydron) crabs and...
