The bacterial populations associated with sea ice sampled from Antarctic coastal areas were investigated by use of a phenotypic approach and a phylogenetic approach based on genes encoding 16S rRNA (16S rDNA). The diversity of bacteria associated with sea ice was also compared with the bacterial diversity of seawater underlying sea ice. Psychrophilic (optimal growth temperature, < or = 15 degrees C; no growth occurring at 20 degrees C) bacterial diversity was found to be significantly enriched… 
Phylogenetic analyses of bacteria in sea ice at Cape Hallett, Antarctica
The findings indicate that the bacterial component of sea ice at Cape Hallett is primarily heterotrophic, and bacteria whose 16S rDNA sequences cluster with species that encode phototrophic genes were detected in sea-ice samples, raising the possibility that bacterial phototrophy may occur in Antarctic sea ice.
Diversity and Structure of Bacterial Communities in Arctic versus Antarctic Pack Ice
A terrestrial influence on the arctic pack ice community was suggested by the presence of limnic phylotypes and high FISH detection rates of these groups as well as high viable counts corroborated the overlap of clone and isolate sequences.
A molecular phylogenetic survey of polar sea ice microbial communities
The findings of this examination corroborate data previously collected during culture based studies indicating bacterial biodiversity increases in SIMCO's displaying high levels of primary productivity and shifts in community composition appear to be associated with alterations in the carbon budget.
Archaeal diversity revealed in Antarctic sea ice
Archaeal abundance in Antarctic sea ice was found to be in low abundance and community diversity was investigated by sequencing cloned 16S rRNA gene PCR products, which clustered with the recently described phylum Thaumarchaeota.
Persistence of bacterial and archaeal communities in sea ice through an Arctic winter
Overall, selection during ice formation and mortality during winter appear to play minor roles in the process of microbial succession that leads to distinctive spring and summer sea ice communities.
Psychrophilic versus psychrotolerant bacteria--occurrence and significance in polar and temperate marine habitats.
The results and literature data indicate that stenothermic cold adapted bacteria play a significant role in the global marine environment and it is suggested to expand the definition of Morita in order to meet the cold adaptation strategies of the bacteria in the various cold habitats.
Phylogenetic Diversity of Numerically Important Arctic Sea-Ice Bacteria Cultured at Subzero Temperature
Overall, these findings suggest limited, heterotrophic bacterial diversity at cold temperatures and may provide insight into the recent evolution of psychrophilic bacteria.
Succession of sea-ice bacterial communities in the Baltic Sea fast ice
Temporal clustering of the TGGE fingerprints was stronger than spatial, although lower ice and underlying water communities always clustered together, pointing to the importance of ice maturity and ice–water interactions in shaping the bacterial communities.
A molecular phylogenetic survey of sea-ice microbial communities (SIMCO).
The findings of this investigation corroborated culture data indicating bacterial biodiversity increased in SIMCO displaying high levels of primary production, however the bacterial communities within SIMCO were highly heterogeneous at the genus/species-level between different samples.
Bacterial Diversity in Sea Ice from the Southern Ocean and the Sea of Okhotsk
Bacterial communities in sea ice were similar to one another at the phylum level, whereas their populations were quite different at the genus level, compared with other studies.


Biodiversity and ecophysiology of bacteria associated with Antarctic sea ice
A total of 135 bacterial strains were isolated from congelation (land fast) sea ice samples and ice algae biomass samples obtained from the coastal areas of the Vestfold Hills in East Antarctica during the summers of 1992–95 to determine the biodiversity of sea ice bacteria.
Sea Ice Microbial Communities: Distribution, Abundance, and Diversity of Ice Bacteria in McMurdo Sound, Antarctica, in 1980
It is proposed that sea ice microbial communities are not only sources of primary production but also sources of secondary microbial production in polar ecosystems and that a detrital food web may be associated with polar sea ice.
Bacterial Plasmids in Antarctic Natural Microbial Assemblages
It is concluded that bacterial plasmids are ubiquitous in natural microbial assemblages of the pristine marine ecosystem of Antarctica.
Antarctic Sea Ice Biota
Trophic interactions among organisms in ice suggest that the ice assemblage is a true community with a well-developed microbial food web.
Sea ice microbial communities. VIII. Bacterial production in annual sea ice of McMurdo Sound, Antarctica
It is proposed that the timing and amount of bacterial production in sea ice are dependent upon the growth phase of associated microalgae, the quantlty and quality of EOC and compounds in the DOM pool available for bacterial growth, rates of bactlvory and herbivory, and retenuon of the platelet ice layer and bottom layer of congelation ice.
Psychroserpens burtonensis gen. nov., sp. nov., and Gelidibacter algens gen. nov., sp. nov., psychrophilic bacteria isolated from antarctic lacustrine and sea ice habitats.
Psychrophilic, yellow-pigmented, seawater-requiring bacteria isolated from the pycnocline of meromictic Burton Lake and from sea ice cores obtained in the Vestfold Hills in eastern Antarctica were characterized and it is proposed that the new taxa are novel bacterial species designated Psychroserpens burtonensis gen. nov.
Microbial ecology of sea ice at a coastal Antarctic site:community composition, biomass and temporal change
The coastal sea ice in the vicinity of Davis Station, Antarctica (68* 35' S, 77* 58' E), supported a diverse microbial community which varied in composition and biomass in response to increasing
Ecology of diatom and bacterial assemblages in water associated with melting summer sea ice in the Weddell Sea, Antarctica
The fate of ice biota released via meltwater into pools of seawater trapped between melting ice floes (crack pools) was followed in late January in the southern Weddell Sea. Low salinity crack pools
