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.

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.
Vibrio diabolicus sp. nov., a new polysaccharide-secreting organism isolated from a deep-sea hydrothermal vent polychaete annelid, Alvinella pompejana.

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.
Olleya marilimosa gen. nov., sp. nov., an exopolysaccharide-producing marine bacterium from the family Flavobacteriaceae, isolated from the Southern Ocean.

Based on phylogenetic, phenotypic, chemotaxonomic and genotypic analyses, this isolate was placed in a novel taxon as Olleya marilimosa gen. nov., sp.

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.
Bacterial abundance and diversity in the Barbados Trench determined by phospholipid analysis

- 1 February 1996
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.
Thermococcus fumicolans sp. nov., a new hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent in the north Fiji Basin.

- 1 October 1996
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.

Chemical composition and molecular weight data revealed that these EPS were very diverse, even among six closely related Pseudoalteromonas isolates, which constituted a new bacterial genus in the family Flavobacteriaceae.

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.
