Marine culturable yeasts in deep-sea hydrothermal vents: species richness and association with fauna.
TLDR
This is the first report of yeasts associated with deep-sea hydrothermal animals, and belongs to Ascomycota and Basidiomycota phyla, with the identification of several genera: Rhodotorula, Rhodosporidium, Candida, Debaryomyces and Cryptococcus. 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
Acquisition of epibiotic bacteria along the life cycle of the hydrothermal shrimp Rimicaris exoculata
TLDR
The results confirmed the occurrence of a symbiosis with Gammaproteobacteria and Epsilonproteobacteria, but more complex than previously assumed, and revealed the presence of active type-I methanotrophic bacteria colonizing the cephalothorax of shrimps from the Rainbow site. Expand
Inorganic carbon fixation by chemosynthetic ectosymbionts and nutritional transfers to the hydrothermal vent host-shrimp Rimicaris exoculata
TLDR
The first demonstration of such capabilities in a decapod crustacean supports the previously discarded hypothesis of transtegumental absorption of dissolved organic matter or carbon as a common nutritional pathway. 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
Chemosynthetic ectosymbionts associated with a shallow-water marine nematode
TLDR
The discovery of potential symbiotic associations of a shallow-water organism with taxa usually associated with deep-sea hydrothermal vents, is new for Nematoda, opening new avenues for the study of ecology and bacterial relationships with meiofauna. Expand
Effect of pH on Thermoanaerobacterium thermosaccharolyticum DSM 571 growth, spore heat resistance and recovery.
TLDR
This work suggests that T. thermosaccharolyticum preserve its ability for germination and outgrowth after a heat-treatment at a low pH where other high resistant spore-forming bacteria like Geobacillus stearothermophilus are unable to grow. Expand
Antimicrobial Peptides and Ectosymbiotic Relationships: Involvement of a Novel Type IIa Crustin in the Life Cycle of a Deep-Sea Vent Shrimp
TLDR
A spatio-temporal correlation between the production of Re-crustin and the main ectosymbiosis-related life-cycle events is shown and a novel and unusual AMP sequence from an extremophile organism is highlighted, highlighting the potential role of AMPs in the establishment of vital ectosYmbiosis along the life cycle of deep-sea invertebrates. Expand
Investigation of bacterial communities within the digestive organs of the hydrothermal vent shrimp Rimicaris exoculata provide insights into holobiont geographic clustering
TLDR
A clear pattern of geographic segregation by vent by vent in OTUs assigned to Epsilonproteobacteria is identified and evidence for differentiation among all communities associated to vents and life stages is detected. Expand
A Nematode of the Mid-Atlantic Ridge Hydrothermal Vents Harbors a Possible Symbiotic Relationship
TLDR
A potential symbiotic role of bacteria with its nematode host is suggested and new research perspectives on vent meiofauna are opened. Expand
