“Following pyrosequencing of rodent blood samples, bacterial communities were found to be comprised primarily of broad niche lineages. “

Metagenomic Assessment of the Eastern Oyster-Associated Microbiota – Ashvini Chauhan – ASM Genome Announcements

“Bacteria associated with the Eastern oysters (Crassostrea virginica) native to Apalachicola Bay, FL, were investigated using 16S rRNA gene amplicon metagenomic sequencing”

Temporal changes in the diazotrophic bacterial communities associated with Caribbean sponges Ircinia stroblina and Mycale laxissima – Fan Zhang, Jan Vicente and Russell T. Hill – Frontiers in Microbiology

“Diazotrophic communities associated with two Caribbean sponges, Ircinia strobilina and Mycale laxissima were studied in a time series during which three individuals of each sponge were collected in four time points “

Species-Specific Viromes in the Ancestral Holobiont Hydra – Juris A. Grasis – PLOS ONE

“We sought to determine the viral communities associating with different Hydra species, whether these viral communities were altered with environmental stress, and whether these viruses affect the Hydra-associated holobiont.”

Plant microbiome

* Microbial Cargo: Do bacteria on symbiotic propagules reinforce the microbiome of lichens? – Ines Aline Aschenbrenner – Environmental Microbiology

“The lung lichen was sampled from three localities in eastern Austria to analyze their associated bacterial communities by bar-coded pyrosequencing, network analysis and fluorescence in situ hybridization.”

Soil microbial properties in Eucalyptus grandis plantations of different ages – C.T. Cortez – Journal of soil science and plant nutrition

“We investigated the soil microbial properties (soil microbial C, N, respiration, carbon use efficiency, and microbial C-to-N ratio) among Eucalyptus grandis plantations of differing ages (1 to 4 years) in Northeast Brazil. “

Soil, rocks, and sediments microbiome

* In-depth analyses of deep subsurface sediments using 454-pyrosequencing reveals a reservoir of buried fungal communities at record-breaking depths – Vanessa Rédou – FEMS Microbiology Ecology

“Here, we investigated the vertical distribution of DNA and RNA fungal signatures within subseafloor sediments of the Canterbury basin (New Zealand) by 454 pyrotag sequencing of fungal genetic markers.”

* Just in time for Halloween: RNA-based molecular survey of biodiversity of limestone tombstone microbiota in response to atmospheric sulfur pollution – Federica Villa – Letters in Applied Microbiology

“In this study, the biofilm microflora of historic limestone tombstones located in a highly polluted urban environment (Cambridge, MA) and in a less polluted location (Lexington, MA), were compared using comprehensive RNA-based molecular analyses of 16S rRNA gene sequences as well as sequences of genes for different pathways of sulfur metabolism (soxB, apsA, dsrA).”

Methane dynamics regulated by microbial community response to permafrost thaw – Carmody K. McCalley – Nature

“Here we show that changes in vegetation and increasing methane emissions with permafrost thaw are associated with a switch from hydrogenotrophic to partly acetoclastic methanogenesis”

Land use and seasonal effects on a Mediterranean soil bacterial community – D. Franciolia – Journal of soil science and plant nutrition

“We compared the fingerprints from both independent replicates and pooled samples to ascertain the best approach for studying the environmental effects on bacterial composition. “

Environmental controls on microbial communities in continental serpentinite fluids
Melitza Crespo-Medina – Frontiers in Microbiology

“Growth was monitored by direct microscopic counts; DNA yield and community composition was assessed at the end of the three month incubation”

Water microbiome

* Microbial transformation of the Deepwater Horizon oil spill – past, present, and future perspectives – Nikole E. Kimes – Frontiers in Microbiology

“In this review, we summarize the microbial response to the oil spill as described by studies performed during the past four years”

Diversity and geochemical structuring of bacterial communities along a salinity gradient in a carbonate aquifer subject to sea water intrusion – Marina Héry – FEMS Microbiology Ecology

“The objective of this study was to characterize and compare bacterial community diversity and composition along a vertical saline gradient in a carbonate coastal aquifer using high throughput sequencing of 16S rRNA genes”

The Variation of Microbial Communities in a Depth Profile of an Acidic, Nutrient-Poor Boreal Bog in Southwestern Finland – Irina Tsitko – OJE

“High throughput sequencing was used to characterize the bacterial communities throughout the bog’s depth profile.”

Spatial distribution patterns of benthic microbial communities along the Pearl Estuary, China – Jiwen Liu – Systematic and Applied Microbiology

“In the present study, benthic microbial communities along the Pearl Estuary, a typical subtropical estuary in China subjected to extensive anthropogenic disturbance, were investigated using 16S rRNA gene-based pyrosequencing.”

Microbes of the built environment

* Bacterial biogeographical patterns in a cooking centre for hospital foodservice – Giuseppina Stellato – International Journal of Food Microbiology

“In this study, the bacterial biogeographical patterns in a hospital cooking centre was studied by 16S rRNA – based culture-independent high-throughput amplicon sequencing in order to provide a comprehensive mapping of the surfaces and tools that come in contact with foods during preparation.”
