Treatment with mixed probiotics induced, enhanced and diversified modulation of the gut microbiome of healthy rats
Future precision microbiome modulation using probiotics should consider the potential interactions of the probiotic strains, and individualized responses due to heterogenous gut microbial compositions.
Culturable bacteria are more common than fungi in floral nectar and are more easily dispersed by thrips, a ubiquitous flower visitor
Bacteria outnumber fungi in northern California flowers and are more easily dispersed by thrips, common flower-visiting insects.
The resistance of the wheat microbial community to water stress is more influenced by plant compartment than reduced water availability
The spread of the plasmid RP4 in a synthetic bacterial community is dependent on the particular donor strain
The effect of an invading antibiotic-resistant isolate on the resistome of the autochthonous community is highly dependent on the particular strain.
Taxonomic and functional characterization of the rumen microbiome of Japanese Black cattle revealed by 16S rRNA gene amplicon and metagenome shotgun sequencing
JB rumen microbiome had relatively higher abundance of fibrolytic bacteria such as F. succinogenes and Ruminococcus spp., increasing the carbohydrate-active enzymes associated with cellulose and hemicellulose degradation.
Watershed and fire severity are stronger determinants of soil chemistry and microbiomes than within-watershed woody encroachment in a tallgrass prairie system
High-severity burns result in a novel soil microbiome regardless of whether applied to grass-dominated or woody-plant invaded patches in a fire-protected, encroached prairie watershed.
Indigenous microbial communities in heavy oil show a threshold response to salinity
Microbial communities from Pitch Lake oil show a sudden threshold-regulated response to salinity, leading to less diverse and uneven communities
Depth-structuring of multi-kingdom soil communities in agricultural pastures
Distribution and network properties of multi-kingdom communities (prokaryotes, fungi, protists and nematodes) along a deep soil profile in a pastoral ecosystem.
Small-scale agricultural grassland management can affect soil fungal community structure as much as continental scale geographic patterns
Across a European transect, comprising five countries, we did show that small-scale agricultural grassland management can affect soil fungal community structure as much as continental scale geographic patterns.
Bacterial community dynamics of tomato hydroponic greenhouses infested with hairy root disease
This study aimed to characterize bacterial communities present in the tomato rhizosphere of plants grown in rockwool, under hydroponic conditions, and either affected or not by hairy root disease.
Site and land-use associations of soil bacteria and fungi define core and indicative taxa
Soil bacterial and fungal communities at thirty sites were yearly assessed over five consecutive years and revealed temporally stable as well as land-use- and site-specific core communities.
Year-round dynamics of amplicon sequence variant communities differ among eukaryotes, Imitervirales and prokaryotes in a coastal ecosystem
A 1-year observation of coastal microbial communities revealed similar but different community dynamics for eukaryotes, their viruses and prokaryotes.
Assembly and potential transmission of the Lens culinaris seed microbiome
Transmission studies and the composition of prokaryotic communities associated with healthy and diseased Aplysina cauliformis sponges suggest that Aplysina Red Band Syndrome is a prokaryotic polymicrobial disease
A combination of transmission studies where healthy and diseased sponges were separated by filters of varying pore size followed by sequencing of partial 16S rRNA genes suggested that ARBS is a prokaryotic yet polymicrobial disease.
Skin bacterial metacommunities of San Francisco Bay Area salamanders are structured by host genus and habitat quality
Metacommunities of skin bacteria that may protect salamanders from fungal skin diseases are structured by host identity and habitat characteristics.
Predictive microbial-based modelling of wheat yields and grain baking quality across a 500 km transect in Québec
Wheat yields and grain quality was predicted with high accuracy from microbial data collected early in the growing season.
Strong reorganization of multi-domain microbial networks associated with primary producers sedimentation from oxic to anoxic conditions in an hypersaline lake
In-depth analysis of microbial networks from the three domains of life reveals how reassociations between microorganisms support the functioning of an hypersaline and hyperalkaline crater lake.
Presence of bacteria capable of PCB biotransformation in stormwater bioretention cells
Transformation of polychlorinated biphenyls (PCBs) was shown in stormwater sediment and bioretention media with presence of active aerobic and anaerobic PCB-degrading bacteria
Temperature dependence of nitrate-reducing Fe(II) oxidation by Acidovorax strain BoFeN1 – evaluating the role of enzymatic vs. abiotic Fe(II) oxidation by nitrite
This study investigates chemical and microbially catalyzed Fe(II) oxidation across a range of temperatures to develop a quantitative description of enzymatic Fe(II) oxidation coupled to nitrate reduction within the environment.
