Ventiella sulfuris Barnard and Ingram, 1990 is the most abundant amphipod species inhabiting the Eastern Pacific Rise (EPR 9°N) vent fields. This vent-endemic species is frequently encountered near colonies of Pompeii worms Alvinella pompejana. V. sulfuris specimens were collected during the oceanographic cruise LADDER II at the Bio9 (9°50.3'N, 2508m depth) hydrothermal vent site. Main objectives were to highlight the occurrence of bacterial symbiosis in V. sulfuris and to hypothesise their… Expand
Dietary analysis on the shallow-water hydrothermal vent crab Xenograpsus testudinatus using Illumina sequencing
TLDR
The findings suggest that both X. testudinatus and P. bidens are scavengers feeding on both prokaryotes and eukaryotes, and provide a database for the food web dynamics of shallow-water hydrothermal vents. Expand
Biogeographical distribution of Rimicaris exoculata resident gut epibiont communities along the Mid-Atlantic Ridge hydrothermal vent sites.
TLDR
The topology of ribotype median-joining networks illustrated a community diversification possibly following demographic expansions, suggesting a more ancient evolutionary history and/or a larger effective population size at Rainbow. Expand
Variation in the diets of hydrothermal vent gastropods
TLDR
The results suggest that the phylogenetic and metabolic diversity of free-living bacteria may play an important and previously overlooked role in facilitating species coexistence among primary consumers at hydrothermal vents and other chemosynthesis-based ecosystems. Expand
Comparison of the gut microbiota in the groundwater amphipod Crangonyx islandicus Svavarsson & Kristjánsson, 2006 (Amphipoda: Crangonyctidae) to biofilms in its spring-source habitat
TLDR
The gut bacteria of C. islandicus indicate that microbial chemolithotrophic activity might fuel the system at least partly and thus explain the amphipod survival in the subsurface of Iceland during repeated glaciation for the past 5 mya. Expand
Discovering symbiosis in the supralittoral: bacterial metabarcoding analysis from the hepatopancreas of Orchestia and Tylos (Crustacea)
Herein, we investigated for the first time the microbiota from the hepatopancreas of the talitrid amphipod Orchestia montagui and the oniscidean isopod Tylos ponticus , two crustacean speciesExpand
Interaction of Vibrio spp. with the Inner Surface of the Digestive Tract of Penaeus monodon
TLDR
Data from the current study suggests that pathogens of P. monodon must be able to colonize the digestive tract, particularly the stomach, where chitin is present, and then they use an array of virulent factors and enzymes to infect their host resulting in disease. Expand
First observations of the behaviour of the deep-sea amphipod Dulichiopsis dianae sp. nov. (Senticaudata, Dulichiidae) in the TAG hydrothermal vent field (Mid-Atlantic Ridge)
TLDR
The present study provides the morphological description of this new species, coupled with in situ observations of its behaviour and lifestyle in the vicinity of the TAG vent field, as well as a review of the amphipod diversity in hydrothermal environments. Expand
Spatial and temporal variations in food web structure from newly-opened habitat at hydrothermal vents.
TLDR
Evidence is provided that attached bacteria formed part of the worms' diet during the course of these colonization experiments, providing evidence that Lepidonotopodium riftense and Branchinotogluma sandersi may have to alternate between detritivorous and predatory feeding strategies. Expand
Extracellular sugar phosphates are assimilated by Streptomyces in a PhoP-dependent manner
TLDR
It is demonstrated that the supply of phosphorylated sugars, under inorganic phosphate limitation, delays the occurrence of the second round of PCD, blocks streptomycetes life cycle at the vegetative state and inhibits antibiotic production. Expand
Impact of freezing and thawing processes on wheat and potato starch gel syneresis
The impact of freezing and thawing processes on gel structure, bound states, and mobility of water in wheat and potato starch gels was investigated, using laser scattering granulometer,Expand

Microbial diversity associated with the hydrothermal shrimp Rimicaris exoculata gut and occurrence of a resident microbial community.
TLDR
The hypothesis of a symbiotic relationship between R. exoculata and its gut epibionts is reinforced, as filamentous bacteria, inserted between microvilli of gut epithelial cells, remained after starvation periods in empty guts, suggesting the occurrence of a resident microbial community. Expand
New insigths on the metabolic diversity among the epibiotic microbial communitiy of the hydrothermal shrimp Rimicaris exoculata
TLDR
The results suggest that three metabolic types may co-occur within the epibiont community associated with Rimicaris exoculata, and the relative abundance of each metabolic type could vary according to the local availability of reduced compounds. Expand
Epibiotic bacteria associated with the recently discovered Yeti crab, Kiwa hirsuta.
TLDR
The Yeti crab, Kiwa hirsuta Macpherson et al., is the single known species in a recently discovered crab family Kiwaidae (Decapoda: Galatheoidea), and the potential for carbon fixation and cycling of reduced and oxidized sulfur appear to exist in the dense microflora that grows on the crab's setae. Expand
Bacterial symbionts and mineral deposits in the branchial chamber of the hydrothermal vent shrimp Rimicaris exoculata: relationship to moult cycle
TLDR
Comparisons with moult cycles of littoral shrimps suggest that the interval between successive exuviations in R. exoculata may be as short as 10 d, and the close correspondence between moult stages, the development of the ectosymbiont community and shrimp colours indicate that colour could be used to rapidly determine shrimp moult levels.

Novel Forms of Structural Integration between Microbes and a Hydrothermal Vent Gastropod from the Indian Ocean
TLDR
Novel forms of structural integration between endo- and episymbiotic microbes and an unusual new species of snail from hydrothermal vents in the Indian Ocean are described, illustrating the great potential of organismal adaptation in chemically and physically challenging deep-sea environments. Expand
Occurrence of Deferribacterales and Entomoplasmatales in the deep-sea Alvinocarid shrimp Rimicaris exoculata gut.
TLDR
The results show that the diversity in the shrimp gut is very low compared to that of the surrounding medium, and the presence of groups that are not found in the external medium suggests the existence of a local microflora. Expand
Indigenous ectosymbiotic bacteria associated with diverse hydrothermal vent invertebrates.
  • S. Goffredi
  • Biology, Medicine
  • Environmental microbiology reports
  • 2010
TLDR
Comparisons of these ectosymbioses to those previously described revealed similarities among the associated microorganisms, suggesting that certain microbes are indigenous to the surfaces of marine invertebrates. Expand
Molecular investigations of the stalked barnacle Vulcanolepas osheai and the epibiotic bacteria from the Brothers Caldera, Kermadec Arc, New Zealand
TLDR
The fatty-acid profiles of the filamentous bacteria and the host barnacle both contained high levels of monounsaturated C16 and C18 fatty acids, and the carbon isotopic compositions of the biomass and monouned fatty acids of both the bacteria and barnacle were nearly identical, which would suggest that the nutrition of the barnacles is highly dependent on bacteria thriving around the barnacle, including the epibiotic bacteria. Expand
Pathways of Carbon and Energy Metabolism of the Epibiotic Community Associated with the Deep-Sea Hydrothermal Vent Shrimp Rimicaris exoculata
TLDR
The data suggest that autotrophic carbon fixation is contributing to the productivity of the epibiotic community with the reductive tricarboxylic acid cycle as one important carbon fixation pathway. Expand
Distribution of bacteria and associated minerals in the gill chamber of the vent shrimp Rimicaris exoculata and related biogeochemical processes
TLDR
The authors' chemical and temperature data indicated that abiotic iron oxidation appears to be kinetically inhibited in the environment of the shrimps, which would explain the lack of iron oxide deposits in the first 2 compartments, and it is proposed that iron oxidation is microbially promoted in the third area.
