Postec, Anne / Le Breton, Claire / Fardeau, Marie-laure / Lesongeur, Francoise / Pignet, Patricia / Querellou, Joel / Ollivier, Bernard / Godfroy, Anne - 2005A novel, thermophilic, anaerobic bacterium that is able to tolerate hydrogen was isolated from a deep-sea hydrothermal chimney collected at the Rainbow field on the Mid-Atlantic Ridge. Cells were rod-shaped and surrounded by a sheath-like outer structure (toga); they were weakly motile by means of...Contributeur (s):

Urios, Laurent / Cueff-gauchard, Valerie / Pignet, Patricia / Postec, Anne / Fardeau, Marie-laure / Ollivier, Bernard / Barbier, Georges - 2004A novel anaerobic, thermophilic and heterotrophic bacterium, designated strain DV114O(T), was isolated from a deep-sea hydrothermal vent sample from the Mid-Atlantic Ridge. The cells were non-motile straight rods, 1-8 mum long and 0-4 mum wide, surrounded by an outer sheath-like structure (toga)....Contributeur (s):

Postec, Anne / Pignet, Patricia / Cueff-gauchard, Valerie / Schmitt, Anne / Querellou, Joel / Godfroy, Anne - 2005The hyperthermophilic archaeon Thermococcus hydrothermalis was cultivated in continuous culture in a gas-lift bioreactor in the absence of elemental sulphur on both proteinaceous and maltose-containing media. Optimal conditions (pH, temperature and gas flow rate), determined on complex media that...Contributeur (s):

Toffin, Laurent / Zink, Klaus / Kato, Chiaki / Pignet, Patricia / Bidault, Adeline / Bienvenu, Nadège / Birrien, Jean-louis / Prieur, Daniel - 2005A piezotolerant, mesophilic, marine lactic acid bacterium (strain LT20(T)) was isolated from a deep sub-seafloor sediment core collected at Nankai Trough, off the coast of Japan. Cells were Gram-positive, rod-shaped, non-sporulating and non-motile. The NaGl concentration range for growth was 0-120...Contributeur (s):

Toffin, Laurent / Bidault, Adeline / Pignet, Patricia / Tindall, Brian / Slobodkin, Alexander / Kato, Chiaki / Prieur, Daniel - 2004A novel piezotolerant, mesophilic, facultatively anaerobic, organotrophic, polarly flagellated bacterium (strain LT13a(T)) was isolated from a deep sediment layer in the Nankai Trough (Leg 190, Ocean Drilling Program) off the coast of Japan. This organism used a wide range of organic substrates as...Contributeur (s):

Urios, Laurent / Cueff, Valerie / Pignet, Patricia / Barbier, Georges - 2004A novel anaerobic, Gram-positive, sporulating and strictly chemoorganoheterotrophic bacterium, designated strain DV1 184 T, was isolated from a deep-sea hydrothermal vent sample from the Mid-Atlantic Ridge. The cells were short, straight rods (4 mum long and 0.8 mum wide) and were motile with...Contributeur (s):

Wery, Nathalie / Lesongeur, Francoise / Pignet, Patricia / Derennes, Veronique / Cambon-bonavita, Marie-anne / Godfroy, Anne / Barbier, Georges - 2001A thermophilic, anaerobic, chemo-organotrophic sulfur-reducing bacterium, designated MV1075(T), was isolated from a deep-sea hydrothermal chimney sample collected on the Mid-Atlantic Ridge. Cells were rod-shaped with a sheath-like outer structure, motile with polar flagella and stained Gramnegative...Contributeur (s):

Alain, Karine / Pignet, Patricia / Zbinden, M / Quillevere, M / Duchiron, F / Donval, Jean-pierre / Lesongeur, Francoise / Raguenes, Gerard / Crassous, Philippe / Querellou, Joel / Cambon-bonavita, Marie-anne - 2002A novel thermophilic, anaerobic, strictly chemoorganoheterotrophic bacterium, designated as AM1114(T), was isolated from a deep-sea hydrothermal vent sample from the East-Pacific Rise (EPR 13degrees N). The cells were long (3-10 mum) rods, motile with peritrichous flagella, and exhibited a Gram-...Contributeur (s):

Wery, Nathalie / Moricet, Jean-marc / Cueff, Valerie / Jean, Joelle / Pignet, Patricia / Lesongeur, Francoise / Cambon-bonavita, Marie-anne / Barbier, Georges - 2001A thermophilic, anaerobic, chemo-organotrophic bacterium, designated MV1087(T), was isolated from a deep-sea hydrothermal chimney sample collected from the Mid-Atlantic Ridge. The cells were straight, motile and stained Gram-negative. Growth was observed from 45 to 65 degreesC, with an optimum...Contributeur (s):

Cruaud, Perrine / Vigneron, Adrien / Pignet, Patricia / Caprais, Jean-claude / Lesongeur, Francoise / Toffin, Laurent / Godfroy, Anne / Cambon-bonavita, Marie-anne - 2015The Sonora Margin cold seeps present a seafloor mosaic pattern consisting of different faunal assemblages and microbial mats. To better understand if sedimentary microbial communities reflect this patchy distribution, all major habitats were investigated using four complementary approaches: 16S...Contributeur (s):

Postec, Anne / Lesongeur, Francoise / Pignet, Patricia / Ollivier, B / Querellou, Joel / Godfroy, Anne - 2007The prokaryotic diversity of culturable thermophilic communities of deep-sea hydrothermal chimneys was analysed using a continuous enrichment culture performed in a gas-lift bioreactor, and compared to classical batch enrichment cultures in vials. Cultures were conducted at 60 degrees C and pH 6.5...Contributeur (s):

Bodennec, Guy / Pignet, Patricia / Caprais, Jean-claude - 1983About 200 km of the Breton coastline was polluted as a consequence of the sinking of the tanker Tanio, on March 7th, 1980. A chemical monitoring was carried out to study the pollution of water (three months) and intertidal sediments (sixteen months). In comparison with the Amoco Cadiz, the...Contributeur (s):

Microbial mats in marine cold seeps are known to be associated with ascending sulfide- and methane-rich fluids. Hence, they could be visible indicators of anaerobic oxidation of methane (AOM) and methane cycling processes in underlying sediments. The Napoli mud volcano is situated in the Olimpi...Contributeur (s):
