Comparison of 16S rRNA gene sequences of genus Methanobrevibacter [PDF]

BMC Microbiology, 2004
The phylogeny of the genus Methanobrevibacter was established almost 25 years ago on the basis of the similarities of the 16S rRNA oligonucleotide catalogs. Since then, many 16S rRNA gene sequences of newly isolated strains or clones representing the genus Methanobrevibacter have been deposited.

Reprocessing 16S rRNA Gene Amplicon Sequencing Studies: (Meta)Data Issues, Robustness, and Reproducibility [PDF]

Frontiers in Cellular and Infection Microbiology, 2021
High-throughput sequencing technology provides an efficient method for evaluating microbial ecology. Different bioinformatics pipelines can be used to convert 16S ribosomal RNA gene amplicon sequencing data into an operational taxonomic unit (OTU) table that is used to analyze microbial communities.

16S classifier: a tool for fast and accurate taxonomic classification of 16S rRNA hypervariable regions in metagenomic datasets. [PDF]

PLoS ONE, 2015
The diversity of microbial species in a metagenomic study is commonly assessed using 16S rRNA gene sequencing. With the rapid developments in genome sequencing technologies, the focus has shifted towards the sequencing of hypervariable regions of 16S ...

Sequence Diversity of Neisseria meningitidis 16S rRNA Genes and Use of 16S rRNA Gene Sequencing as a Molecular Subtyping Tool [PDF]

Journal of Clinical Microbiology, 2002
ABSTRACT We investigated the diversity of the primary sequences of 16S rRNA genes among Neisseria meningitidis strains (Men) and evaluated the use of this approach as a molecular subtyping tool. We aligned and compared a 1,417-bp fragment of the 16S rRNA gene from 264 Men strains of serogroups A, B, C, and

Quantifying dominant bacterial genera detected in metagenomic data from fish eggs and larvae using genus‐specific primers

MicrobiologyOpen, 2022
The goal of this study was to design genus‐specific primers for rapid evaluation of the most abundant bacterial genera identified using amplicon‐based sequencing of the 16S rRNA gene in fish‐related samples and surrounding water. Efficient genus‐specific

Amplicon Sequence Variants Artificially Split Bacterial Genomes into Separate Clusters

mSphere, 2021
16S rRNA gene sequencing has engendered significant interest in studying microbial communities. There has been tension between trying to classify 16S rRNA gene sequences to increasingly lower taxonomic levels and the reality that those levels were ...

Strategy for the identification of micro-organisms producing food and feed products : bacteria producing food enzymes as study case [PDF]

, 2020
Recent European regulations require safety assessments of food enzymes (FE) before their commercialization. FE are mainly produced by micro-organisms, whose viable strains nor associated DNA can be present in the final products.

16S-ITS-23S rRNA operon segment sequencing provides necessary and sufficient conditions for bacterial species-specific identification

Инфекция и иммунитет, 2022
Introduction. Sequencing of the 16S rRNA gene is the predominant method for assessing microbial communities and strain molecular identification. The short reads (2nd generation sequencing)-based technology does not allow analysis beyond the 16S rRNA gene.

Choice of 16S Ribosomal RNA Primers Impacts Male Urinary Microbiota Profiling

Frontiers in Cellular and Infection Microbiology, 2022
Accessibility to next-generation sequencing (NGS) technologies has enabled the profiling of microbial communities living in distinct habitats. 16S ribosomal RNA (rRNA) gene sequencing is widely used for microbiota profiling with NGS technologies.
