| As critical primary producers and recyclers of organic matter, the diversity of marine protists has been extensively explored by high-throughput barcode sequencing. However, classification of short metabarcoding sequences into traditional taxonomic units is not trivial, especially for lineages mainly known by their genetic fingerprints. This is the case for the widespread Amoebophrya ceratii species complex, parasites of their dinoflagellate congeners. We used genetic and phenotypic characters, applied to 119 Amoebophrya individuals sampled from the same geographic area, to construct practical guidelines for species delineation that could be applied in DNA/RNA based diversity analyses. Based on the internal transcribed spacer (ITS) regions, ITS2... |

| Introduction : Recently, the use of culture-independent molecular phylogenetic techniques has greatly increased our inventory of archaeal and bacterial diversity at deep-sea vents (e.g. Harmsen et al., 1997; Reysenbach et al., 2000; Takai et al., 2001) and several of the lineages appear to be endemic to deep-sea vents (Reysenbach et al., 2000b; Takai et al, 2000; Longnecker & Reysenbach, 2001). Using environmental data, some of these lineages have now been cultivated (L'Haridon et al., 1998; Campbell et al., 2001). For example, until recently, the chemolithoautotrophic and thermophilic bacterial lineage, the Aquificales, was restricted to shallow marine vents and terrestrial thermal springs. However, as part of two independent studies, one in... |

| Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world's oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits. |

| A thermophillic, non-spore-forming, marine, sulfate-reducing bacterium, strain SL6(T), was isolated from deep-sea hydrothermal sulfides collected at Guaymas Basin. The Gram-negative-staining cells occurred singly or in pairs as small, highly motile rods. The temperature range for growth was 50-80degreesC with an optimum at 75degreesC. The pH range for growth at 70degreesC was 6.3-6.8, with an optimum at 6.5. The NaCl concentration range for growth was 5.55 g l(-1), with an optimum at 30 g l(-1). H-2 and CO2 were the only substrates for growth and sulfate reduction. However, growth was stimulated by several organic compounds. Sulfur, thiosulfate, sulfite, cystine, nitrate and fumarate were not used as electron acceptors. Pyruvate, lactate and malate did not... |
