The HaPoGé survey was planned due to a scientific opportunity tender for the HROV Ariane, it follows the test AtlantHrov campaign technique, which took place from May 26 to June 9, 2017. HaPoGé is the first scientific cruise of the HROV Ariane in Atlantic ocean, aboard a coastal vessel the “Côtes de la Manche”. It took place from July 12 to July 19, 2017. The HROV dives were located in the Capbreton canyon. This survey involved scientist from Ifremer, Bordeaux and Pau universities. It had several objectives: i) to know the morphology of rockfall and sediment areas, ii) to sample in situ the rocky outcrops and characterize the benthic communities and iii) to determine the nature, levels of concentrations and distribution of contaminants in sediments and the...

A novel Gram-negative, non-spore-forming, vibrio-shaped, anaerobic, alkaliphilic, sulfate-reducing bacterium, designated strain PAR22NT, was isolated from sediment samples collected at an alkaline crater lake in Guanajuato (Mexico). Strain PAR22NT grew at temperatures between 15 and 37 °C (optimum, 32 °C), at pH between pH 8.3 and 10.1 (optimum, pH 9.0–9.6), and in the presence of NaCl up to 10 %. Pyruvate, 2-methylbutyrate and fatty acids (4–18 carbon atoms) were used as electron donors in the presence of sulfate as a terminal electron acceptor and were incompletely oxidized to acetate and CO2. Besides sulfate, both sulfite and elemental sulfur were also used as terminal electron acceptors and were reduced to sulfide. The predominant fatty acids were...
