Evolution in action: Habitat-transition leads to genome-streamlining in Methylophilaceae (Betaproteobacteriales) [PDF]

open access: yesThe ISME Journal, 2019
AbstractThe most abundant aquatic microbes are small in cell and genome size. Genome-streamlining theory predicts gene loss caused by evolutionary selection driven by environmental factors, favouring superior competitors for limiting resources. However, evolutionary histories of such abundant, genome-streamlined microbes remain largely unknown. Here we

Bacteriome composition analysis of selected mineral water occurrences in Serbia [PDF]

open access: yesArchives of Biological Sciences, 2022
Bacterial metabarcoding analysis by 16S rDNA of five occurrences of mineral waters in Serbia (Torda, Slankamen Banja, Lomnički Kiseljak, Velika Vrbnica and Obrenovačka Banja) indicated the presence of a high percentage of the Proteobacteria phylum ...

Genome-resolved metagenomics identifies novel active microbes in biogeochemical cycling within methanol-enriched soil. [PDF]

open access: yesEnviron Microbiol Rep
Ensemble binning of environmental metagenomes significantly improves the analysis of complex datasets. A re‐analysis of metagenomes, derived from labelled DNA extracted from 13C methanol‐enriched rhizosphere soils, yielded a substantial number of metagenome‐assembled genomes.

Bio-Augmentation of S2− Oxidation for a Heavily Polluted River by a Mixed Culture Microbial Consortium

open access: yesFermentation, 2023
The redox balance of inorganic sulfur in heavily polluted rivers might be disrupted, making sulfur reduction a major metabolic pathway of sulfate-reducing bacteria (SRB), leading to a massive accumulation of S2− and blackening the water bodies.

Biogeochemical Activity of Methane-Related Microbial Communities in Bottom Sediments of Cold Seeps of the Laptev Sea

open access: yesMicroorganisms, 2023
Bottom sediments at methane discharge sites of the Laptev Sea shelf were investigated. The rates of microbial methanogenesis and methane oxidation were measured, and the communities responsible for these processes were analyzed.

Oxygen availability is a major factor in determining the composition of microbial communities involved in methane oxidation [PDF]

open access: yesPeerJ, 2015
We have previously observed that methane supplied to lake sediment microbial communities as a substrate not only causes a response by bona fide methanotrophic bacteria, but also by non-methane-oxidizing bacteria, especially by members of the family ...

Methylotenera mobilis gen. nov., sp. nov., an obligately methylamine-utilizing bacterium within the family Methylophilaceae [PDF]

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2006
A novel obligate methylamine utilizer (strain JLW8T), isolated from Lake Washington sediment, was characterized taxonomically. The isolate was an aerobic, Gram-negative bacterium. Cells were rod-shaped and motile by means of a single flagellum. Reproduction was by binary fission and no resting bodies were formed.

Metagenomic Insight into Environmentally Challenged Methane-Fed Microbial Communities

open access: yesMicroorganisms, 2020
In this study, we aimed to investigate, through high-resolution metagenomics and metatranscriptomics, the composition and the trajectories of microbial communities originating from a natural sample, fed exclusively with methane, over 14 weeks of ...

Analysis of denitrification performance and microbial community structure in a bio-electrochemical reactor under different current densities with wheat-rice stone powder

open access: yesWater Reuse, 2022
Nitrate widely exists in water pollution and is the most stable form of nitrogen pollution. This study investigated the effect of the current density (CD) and the wheat-rice stone powder (WP) on denitrification performance, microbial diversity and enzyme
