Planctomycetes in boreal and subarctic wetlands: diversity patterns and potential ecological functions
This mini-review summarizes the currently available knowledge on the abundance, phylogenetic diversity, specific adaptations and potential roles of planctomycetes in peatlands.
The known and the unknown in soil microbial ecology
Despite the significant achievements in soil microbial ecology over the past years, many common methodical approaches have important limitations that need to be addressed as well as our way of thinking about soil as the ecosystem component.

Deforestation impacts network co-occurrence patterns of microbial communities in Amazon soils
Deforestation of Amazon rainforest alters soil microbial community and physicochemical properties, which subsequently alter microbially mediated biogeochemical processes, notably nitrogen cycle. The Amazon Rainforest is the largest terrestrial ecosystem on Earth and deforestation changes co-occurrence patterns of microbial communities with potential consequences to biogeochemical cycles
Nitrogen availability facilitates phosphorus acquisition by bloom-forming cyanobacteria
Nitrogen availability facilitates phosphorus acquisition by the activation of high-affinity phosphate uptake systems of N-deficient cyanobacteria during the onset of bloom formation
Genomic insights into the metabolism of ‘Candidatus Defluviicoccus seviourii’, a member of Defluviicoccus cluster III abundant in industrial activated sludge
Spruce and beech as local determinants of forest fungal community structure in litter, humus and mineral soil
Spruce and beech as local determinants of forest fungal community structure in litter, humus and mineral soil.
Highly competitive fungi manipulate bacterial communities in decomposing beech wood (Fagus sylvatica)
The identity of the bacteria living in wood is influenced by the identity of the fungi living there.
An Acetobacterium strain isolated with metallic iron as electron donor enhances iron corrosion by a similar mechanism as Sporomusa sphaeroides
Sporomusa and Acetobacterium strains isolated with metallic iron as electron donor enhance Fe(0) corrosion
The soil microbial community of turf: linear and nonlinear changes of taxa and N-cycling gene abundances over a century-long turf development
Turf, an apparent copiotrophic environment, harbors diverse microbial taxa; the abundances of most taxa from the phylum to operational taxonomic unit level changed nonlinearly along turf development.
Polychaete mucopolysaccharide alters sediment microbial diversity and stimulates ammonia-oxidising functional groups
Mucus secreted by invertebrates living in sediment can increase the abundance of nitrogen-processing microbial groups, but this invertebrate–microbe interaction is not currently considered in sediment nitrogen models.
Bacteriome-associated Wolbachia of the parthenogenetic termite Cavitermes tuberosus
The parthenogenetic termite Cavitermes tuberosus and the reproductive parasite Wolbachia are partners that likely engage in an intimate insect-bacteria nutritional partnership.
The morphology and metabolic potential of the Chloroflexi in full-scale activated sludge wastewater treatment plants
The core members of the Chloroflexi community in full-scale wastewater treatment plants were identified as novel genera and their ecophysiology characterised, suggesting roles in carbohydrate breakdown and sludge settleability problems.
Ectosymbiotic bacterial microbiota densely colonize the surface of thelastomatid nematodes in the gut of the wood-feeding cockroach Panesthia angustipennis
Discovery and ecology of a bacterial consortium attached to the surface of pinworms (nematodes) in guts of cockroaches.
Influence of physico-chemical characteristics of sediment on the in situ spatial distribution of F-specific RNA phages in the riverbed
The heterogeneous presence of fine sands, clays and iron-bearing phases has an influence on the in situ spatial distribution of faecal phages in riverbed sediment.
Diversity and metabolism of xylose and glucose fermenting microbial communities in sequencing batch or continuous culturing
We demonstrate that sequencing batch culturing promotes r-organisms identified as Enterobacteriaceae, while continuous culturing promotes K-organisms identified as Enterobactericiaceae, Clostridium and Lachnospiraceae.
Bacterial endophyte antagonism toward a fungal pathogen in vitro does not predict protection in live plant tissue
Investigators tested whether lab-based measurements accurately predicted bacterial antagonism of a wheat fungal pathogen in plants using a series of increasingly realistic experimental assays.
Soil pH dominates elevational diversity pattern for bacteria in high elevation alkaline soils on the Tibetan Plateau

Fermenters in the earthworm gut: do transients matter?
Earthworms are bioengineers of the terrestrial biosphere, and their environmental impact and nutrition are in part linked to fermentative gut microbes, the nature of which are examined in this study.
Enrichment of peat yields novel methanogens: approaches for obtaining uncultured organisms in the age of rapid sequencing
In this study, we used classical culture-based methods paired with modern sequencing to highlight the potential benefits of enrichment-based approaches in identifying novel methanogens from northern peatlands.
Seasonal, sub-seasonal and diurnal variation of soil bacterial community composition in a temperate deciduous forest
Soil bacterial communities are distinct across the four seasons and at the sub-seasonal scale, but not the dirunal-scale, in a temperate deciduous forest.
Microbial community composition of sediments influenced by intensive mariculture activity
Excess nutrients in the sediment of a mariculture site favor the growth of bacteria that thrive in high amounts of organic matter.
Human skin microbiota is a rich source of bacteriocin-producing staphylococci that kill human pathogens
In the search for novel topical skin therapies, we have examined skin-derived bacteriocins, produced by microbes which have evolved in such a way as to outcompete pathogens, and successfully colonise the skin environment.
