The global niche models suggest that oceanic microbial communities will experience complex changes as a result of projected future climate conditions, and these changes may have large impacts on ocean ecosystems and biogeochemical cycles.
Microbial production of recalcitrant dissolved organic matter: long-term carbon storage in the global ocean
The microbial carbon pump is proposed as a conceptual framework to address the important, multifaceted biogeochemical problem of fixed carbon in the upper ocean.

It is demonstrated that oceanic systems contain a large pool of diverse picocyanobacteria, and further suggest that new genotypes or ecotypes of picocianobacteria will continue to emerge, as microbial consortia are explored with advanced sequencing technology.
Distinct distribution pattern of abundance and diversity of aerobic anoxygenic phototrophic bacteria in the global ocean.
The results suggest that AAPB abundance and diversity follow opposite trends from oligotrophic to eutrophic regimes in the ocean, and the Indian Ocean contained relatively high AAPB% compared with the other two oceans, corresponding to the high primary production in this region.
Bacterial diversity in the snow over Tibetan Plateau Glaciers
Bacterial diversity was unexpectedly high in the snow habitats of the world’s highest plateau, with 15 common genera distributed widely among the glaciers, according to culture-independent molecular analysis of 16S rRNA gene clone library and flow cytometry approaches.
Genome sequences of siphoviruses infecting marine Synechococcus unveil a diverse cyanophage group and extensive phage-host genetic exchanges.
This study revealed that cyanosiphovirus genes involved in DNA metabolism and replication share high sequence homology with those in cyanobacteria, and further phylogenetic analysis based on these genes suggests that ancient and selective genetic exchanges occurred, possibly due to past prophage integration.

The results indicated that the biogeographic distribution of bacteria in the SCS is the result of both environmental control and distance decay.
