Anoxic nitrification in marine sediments [PDF]

open access: yes, 2004
Nitrate peaks are found in pore-water profiles in marine sediments at depths considerably below the conventional zone of oxic nitrification. These have been interpreted to represent nonsteady- state effects produced by the activity of nitrifying ...

Reading canonical and modified nucleobases in 16S ribosomal RNA using nanopore native RNA sequencing.

open access: yesPLoS ONE, 2019
The ribosome small subunit is expressed in all living cells. It performs numerous essential functions during translation, including formation of the initiation complex and proofreading of base-pairs between mRNA codons and tRNA anticodons.

Microbial communities in dark oligotrophic volcanic ice cave ecosystems of Mt. Erebus, Antarctica. [PDF]

open access: yes, 2015
The Earth's crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth's surface.

Chromosomal 16S Ribosomal RNA Methyltransferase RmtE1 in Escherichia coli Sequence Type 448

open access: yesEmerging Infectious Diseases, 2017
We identified rmtE1, an uncommon 16S ribosomal methyltransferase gene, in an aminoglycoside- and cephalosporin-resistant Escherichia coli sequence type 448 clinical strain co-harboring blaCMY-2.

Ion torrent-based transcriptional assessment of a Corynebacterium pseudotuberculosis equi strain reveals denaturing high-performance liquid chromatography a promising rRNA depletion method [PDF]

open access: yes, 2013
Corynebacterium pseudotuberculosis equi is a Gram-positive pathogenic bacterium which affects a variety of hosts. Besides the great economic losses it causes to horse-breeders, this organism is also known to be an important infectious agent to cattle and

Selection of Peptides Targeting Helix 31 of Bacterial 16S Ribosomal RNA by Screening M13 Phage-Display Libraries

open access: yesMolecules, 2011
Ribosomal RNA is the catalytic portion of ribosomes, and undergoes a variety of conformational changes during translation. Structural changes in ribosomal RNA can be facilitated by the presence of modified nucleotides. Helix 31 of bacterial 16S ribosomal

The impact of molecular biology on assessment of water quality: advantages and limitations of current techniques [PDF]

open access: yes, 1997
The advent of molecular biology has had a dramatic impact on all aspects of biology, not least applied microbial ecology. Microbiological testing of water has traditionally depended largely on culture techniques.

Microbial residence time is a controlling parameter of the taxonomic composition and functional profile of microbial communities. [PDF]

open access: yes, 2019
A remaining challenge within microbial ecology is to understand the determinants of richness and diversity observed in environmental microbial communities.

Association between semen microbiome disorder and sperm DNA damage

open access: yesMicrobiology Spectrum
DNA fragmentation index (DFI), a new biomarker to diagnose male infertility, is closely associated with poor reproductive outcomes. Previous research reported that seminal microbiome correlated with sperm DNA integrity, suggesting that the microbiome may

Influence of 16S Ribosomal RNA Gene Polymerase Chain Reaction and Sequencing on Antibiotic Management of Bone and Joint Infections

open access: yesCanadian Journal of Infectious Diseases and Medical Microbiology, 2013
INTRODUCTION: Amplification of the 16S ribosomal RNA gene by polymerase chain reaction (PCR) followed by analysis of generated sequences can be an important adjunct to conventional cultures.
