Bacterial Exopolysaccharides from Extreme Marine Environments with Special Consideration of the Southern Ocean, Sea Ice, and Deep-Sea Hydrothermal Vents: A Review
TLDR
High molecular weight carbohydrate polymers that make up a substantial component of the extracellular polymers surrounding most microbial cells in the marine environment and enhance the survival of marine bacteria by influencing the physicochemical environment around the bacterial cell are studied. Expand
Production of exopolysaccharides by Antarctic marine bacterial isolates
TLDR
This study was undertaken to examine and characterize Antarctic marine bacterial isolates and the exopolysaccharides they produce in laboratory culture and to evaluate the phytochemical properties of these compounds. Expand
Vibrio diabolicus sp. nov., a new polysaccharide-secreting organism isolated from a deep-sea hydrothermal vent polychaete annelid, Alvinella pompejana.
TLDR
In batch cultures in the presence of glucose, this organism produced an innovative exopolysaccharide that had high contents of both uronic acids and hexosamines and was similar to other polysaccharides with interesting biological activities. Expand
Bacterial abundance and diversity in the Barbados Trench determined by phospholipid analysis
TLDR
The Barbados trench is characterized by large fields of volcanoes and mounds located over a distance of 30 km above the northern slope of a basement ridge corresponding to an inactive transform fault and revealed the presence of sulfur-oxidizing bacteria common to many deep-sea sites but also a large contribution of type I and type II methanotrophs to the eubacterial biomass. Expand
Olleya marilimosa gen. nov., sp. nov., an exopolysaccharide-producing marine bacterium from the family Flavobacteriaceae, isolated from the Southern Ocean.
TLDR
Based on phylogenetic, phenotypic, chemotaxonomic and genotypic analyses, this isolate was placed in a novel taxon as Olleya marilimosa gen. nov., sp. Expand
Thermococcus fumicolans sp. nov., a new hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent in the north Fiji Basin.
TLDR
An extremely thermophilic archaeon, strain ST557T (T = type strain), was isolated from a deep-sea hydrothermal vent in the North Fiji Basin and Sequencing of the 16S rRNA gene revealed that it belongs to the genus Thermococcus, and it is proposed that this organism should be placed in a new species, TherMococcus fumicolans. Expand
Desulfohalobium retbaense gen. nov., sp. nov., a Halophilic Sulfate-Reducing Bacterium from Sediments of a Hypersaline Lake in Senegal
TLDR
On the basis of the morphological and physiological properties of this strain, it is proposed that it should be classified in a new genus, Desulfohalobium, which includes a single species, Des sulfurate-reducing bacterial strain retbaense. Expand
Thermosipho melanesiensis sp. nov., a new thermophilic anaerobic bacterium belonging to the order Thermotogales, isolated from deep-sea hydrothermal vents in the southwestern Pacific Ocean.
TLDR
A new thermophilic, anaerobic rod-shaped bacterium, strain BI429T was isolated from the gills of a deep-sea vent hydrothermal mussel, Bathymodiolus brevior, from the Lau Basin and is proposed as a new species, Thermosipho melanesiensis. Expand
Biology and ecology of the “Pompeii worm” (Alvinella pompejana Desbruyères and Laubier), a normal dweller of an extreme deep-sea environment: A synthesis of current knowledge and recent developments
Abstract Alvinella pompejana, the “Pompeii worm” lives on active hydrothermal edifices at deep-sea vents of the East Pacific Rise. The physical and chemical patterns of its microhabitat wereExpand
Thermococcus hydrothermalis sp. nov., a new hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent.
TLDR
This strain is a strictly anaerobic coccus, and its cells range from 0.8 to 2 microns in diameter, and Sequencing of the 16S rRNA gene showed that strain AL662T belongs to the genus Thermococcus. Expand
