Non-human microbiome, June 17

You waited for it: the Cannabis microbiome! But also microbiotas of salmon, a quail, coral, sponges, water, and ice.

Bird microbiome

Cultivable Bacterial Microbiota of Northern Bobwhite (Colinus virginianus): A New Reservoir of Antimicrobial Resistance? – Hongwen Su – PLOS ONE

“Firmicutes was the most commonly encountered phylum (57%) followed by Actinobacteria (24%), Proteobacteria (17%) and Bacteroidetes (0.02%). Extensive diversity in the species composition of quail microbiota was observed among individual birds and anatomical locations.”

Fish microbiome

Pyrosequencing-based characterization of gastrointestinal bacteria of Atlantic salmon (Salmo salar L.) within a commercial mariculture system – K.Z. Zarkasi – Journal of Applied Microbiology

“Salmon GI tract bacterial communities commercially farmed in south-eastern Tasmania were analysed, over a 13-month period across a standard commercial production farm cycle, using 454 16S rRNA-based pyrosequencing. “

Coral and sponge microbiome

Community Shifts in the Surface Microbiomes of the Coral Porites astreoides with Unusual Lesions – Julie L. Meyer – PLOS ONE

“The presence of lesions in P. astreoides coincided with a decrease in the relative abundance of Endozoicomonas, rather than the appearance of specific pathogenic taxa.”

Bacterial suspects identified in Caribbean coral deaths – NewScientist

“Three bacteria seem to be responsible for a disease that has killed most of the Caribbean’s reef-building corals.”

Effects of salinity on antibiotic production in sponge-derived Salinispora actinobacteria – Y.K. Ng – Journal of Applied Microbiology

Fingerprint data were generated from extracts of S. arenicola broth cultures grown in media of varying salt (NaCl) concentrations.”

Plants microbiome

Understanding Cultivar-Specificity and Soil Determinants of the Cannabis Microbiome – Max E. Winston – PLOS ONE

“Here we present the first description of the endorhiza-, rhizosphere-, and bulk soil-associated microbiome of five distinct Cannabis cultivars. Bacterial communities of the endorhiza showed significant cultivar-specificity.”

The Role of Abiotic Environmental Conditions and Herbivory in Shaping Bacterial Community Composition in Floral Nectar – Michal Samuni-Blank – PLOS ONE

“ We studied culturable bacterial communities in Asphodelus aestivus floral nectar and in its typical herbivorous bug Capsodes infuscatus, along an aridity gradient.”

Microbial community structure during fluoranthene degradation in the presence of plants – S. Storey – Journal of Applied Microbiology

“Bacterial and fungal community composition in the rhizosphere was significantly different from that in nonrhizospheric and unplanted samples.”

Soil microbiome

Omics-based interpretation of synergism in a soil-derived cellulose-degrading microbial community – Yizhuang Zhou – Scientific Reports

“Analyses of reconstructed bacterial draft genomes from all seven uncultured phylotypes in F1RT indicate that its constituent microbes cooperate in both cellulose-degrading and other important metabolic processes.”

Structure, Composition and Metagenomic Profile of Soil Microbiomes Associated to Agricultural Land Use and Tillage Systems in Argentine Pampas – Belén Carbonetto – PLOS ONE

“The aim of our study was to investigate the effects of agricultural land use on community structure, composition and metabolic profiles on soil microbiomes of Argentine Pampas.”

 

Dust microbiome

Richness and Diversity in Dust Stormborne Biomes at the Southeast Mediterranean – Itzhak Katra – Scientific Reports

“In addition to the physico-chemical compositions, organismal diversities of dust from two storm events in southern Israel, December 2012 (Ev12) and January 2013 (Ev13), were determined by pyro-sequencing using primers universal to 16S and 18S rRNA genes and compared.”

Bioreactors

The maximum specific hydrogen-producing activity of anaerobic mixed cultures: definition and determination – Yang Mu – Scientific Reports

“ Our results demonstrate that this novel SHAm assay was a rapid, accurate and simple methodology for determining the hydrogen-producing activity of anaerobic mixed cultures.”

Methanogenic community changes, and emissions of methane and other gases, during storage of acidified and untreated pig slurry – S.O. Petersen – Journal of Applied Microbiology

“Pig slurry from two farms, acidified by different techniques or untreated, was stored for 83 days in a pilot-scale facility. Methanogens were characterized before and after storage by T-RFLP and qPCR targeting mcrA.”

Water and ice

The Characterization of RNA Viruses in Tropical Seawater Using Targeted PCR and Metagenomics – Alexander I. Culley – mBio

“In this study, we investigated the diversity of the RNA virus assemblages in tropical coastal seawater samples using targeted PCR and metagenomics.”

Variations of algal communities cause darkening of a Greenland glacier – Stefanie Lutz – FEMS Microbiology Ecology

“We have assessed the microbial ecology on the surface of Mittivakkat glacier in SE-Greenland during the exceptional high melting season in July 2012 when the so far most extreme melting rate for the Greenland Ice Sheet has been recorded.”

Pyrosequencing reveals correlations between extremely acidophilic bacterial communities with hydrogen sulphide concentrations, pH and inert polymer coatings at concrete sewer crown surfaces – E. Pagaling – Journal of Applied Microbiology

“Pyrosequencing and cloning showed that Mycobacterium and Acidithiobacillus dominated the acidophilic microbial communities. Methylacidiphilum was also dominant in samples where methane was detected.”

Bacterial community dynamics during the early stages of biofilm formation in a chlorinated experimental drinking water distribution system: implications for drinking water discolouration – I. Douterelo – Journal of Applied Microbiology

“Selected samples were analysed by cloning and sequencing of the 16S rRNA gene. Fingerprinting analysis revealed significant changes in the bacterial community structure over time (P < 0·05). “
