TLDR
A group of strains with potent extracellular enzymic activity were isolated from the surfaces of the chain-forming sea-ice diatom Melosira and from an unidentified macrophyte collected from the Eastern Antarctic coastal zone and it was recognized that the species Cytophaga uliginosa possessed 16S rDNA sequences and phenotypic and chemotaxonomic traits similar to those of other Cellulophaga species.
Revised Taxonomy of the Methanotrophs: Description of Methylobacter gen. nov., Emendation of Methylococcus, Validation of Methylosinus and Methylocystis Species, and a Proposal that the Family
TLDR
Numerical taxonomic, DNA-DNA hybridization, and phospholipid fatty acid composition analyses were performed on an extensive range of methanotrophic strains, including reference strains and environmental isolates obtained from sites throughout eastern Australia, and clarified group I and II methnotroph genus and species interrelationships.
Diversity and association of psychrophilic bacteria in Antarctic sea ice
TLDR
It is proposed that ice diatom assemblages provide niches conducive to the proliferation of a diverse array of psychrophilic bacterial species.
Algoriphagus ratkowskyi gen. nov., sp. nov., Brumimicrobium glaciale gen. nov., sp. nov., Cryomorpha ignava gen. nov., sp. nov. and Crocinitomix catalasitica gen. nov., sp. nov., novel flavobacteria
TLDR
It is proposed that the three genera Brumimicrobium, Cryomorpha and Crocinitomix belong to a new family, Cryomorphaceae fam.
Biodiversity, Community Structural Shifts, and Biogeography of Prokaryotes within Antarctic Continental Shelf Sediment
TLDR
Between 18 and 65% of 16S rDNA phylotypes detected in a wide range of coastal and open ocean sediments possessed high levels of sequence similarity with the MGP sediment phylotypes, indicating that many sediment prokaryote phylotype groups defined in this study are ubiquitous in marine sediment.
Shewanella gelidimarina sp. nov. and Shewanella frigidimarina sp. nov., novel Antarctic species with the ability to produce eicosapentaenoic acid (20:5 omega 3) and grow anaerobically by
TLDR
On the basis of polyphasic taxonomic data, the Antarctic iron-reducing strains are placed in two new species, Shewanella frigidimarina sp.
Psychroflexus torquis gen. nov., sp. nov., a psychrophilic species from Antarctic sea ice, and reclassification of Flavobacterium gondwanense (Dobson et al. 1993) as Psychroflexus gondwanense gen.
TLDR
Evidence based on phylogeny and fatty acid profiles supports the conclusion that the taxa are close relatives distinct from other bacterial groups, and it is proposed that the sea ice strains represent a novel taxon designated Psychroflexus torquis gen. nov.
Novel members of the family Flavobacteriaceae from Antarctic maritime habitats including Subsaximicrobium wynnwilliamsii gen. nov., sp. nov., Subsaximicrobium saxinquilinus sp. nov., Subsaxibacter
Several orange- and yellow-pigmented, halophilic, strictly aerobic, chemoheterotrophic, Gram-negative strains were isolated during investigations of maritime Antarctic habitats, including coastal
Algicidal Effects of a Novel MarinePseudoalteromonas Isolate (Class Proteobacteria, Gamma Subdivision) on Harmful Algal Bloom Species of the GeneraChattonella, Gymnodinium, andHeterosigma
TLDR
A yellow-pigmented Pseudoalteromonasstrain, designated strain Y, was isolated from the Huon Estuary in southern Tasmania, Australia that had potent algicidal effects on harmful algal bloom species and showed a chemotactic, swarming behavior that resulted in localized high concentrations around target organisms.
