Molecular cloning of the rRNA genes of Prevotella bryantii B14

open access: yesActa Agriculturae Slovenica, 2000
Parts of the rRNA operons of anaerobic rumen bacteria Prevotella bryantii B14 were cloned. 350 colonies carrying pBluescriptII with HindIII DNA fragments were screened with 16S rDNA specific probe and six positive clones were obtained.

Linking 16S rRNA Gene Classification to amoA Gene Taxonomy Reveals Environmental Distribution of Ammonia-Oxidizing Archaeal Clades in Peatland Soils

open access: yesmSystems, 2021
A highly resolved taxonomy for ammonia-oxidizing archaea (AOA) based on the alpha subunit of ammonia monooxygenase (amoA) was recently established, which uncovered novel environmental patterns of AOA, challenging previous generalizations.

Diagnostic Yield and Impact on Antimicrobial Management of 16S rRNA Testing of Clinical Specimens

open access: yesMicrobiology Spectrum, 2022
16S rRNA gene sequencing is increasingly used in clinical practice for bacterial identification of clinical specimens. However, studies on its applicability to direct clinical specimens are limited. Here, we studied the diagnostic yield and impact of 16S

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

open access: yes, 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.

Taxonomy of anaerobic digestion microbiome reveals biases associated with the applied high throughput sequencing strategies [PDF]

open access: yes, 2018
In the past few years, many studies investigated the anaerobic digestion microbiome by means of 16S rRNA amplicon sequencing. Results obtained from these studies were compared to each other without taking into consideration the followed procedure for ...

Microvariation Artifacts Introduced by PCR and Cloning of Closely Related 16S rRNA Gene Sequences [PDF]

open access: yes, 2001
A defined template mixture of seven closely related 16S-rDNA clones was used in a PCR-cloning experiment to assess and track sources of artifactual sequence variation in 16S rDNA clone libraries. At least 14% of the recovered clones contained aberrations.

Increased variability of microbial communities in restored salt marshes nearly 30 years after tidal flow restoration [PDF]

open access: yes, 2012
We analyzed microbial diversity and community composition from four salt marsh sites that were impounded for 40–50 years and subsequently restored and four unimpounded sites in southeastern Connecticut over one growing season.

In-Depth Analysis of Bacillus anthracis 16S rRNA Genes and Transcripts Reveals Intra- and Intergenomic Diversity and Facilitates Anthrax Detection

open access: yesmSystems, 2022
Analysis of 16S rRNA (rRNA) genes provides a central means of taxonomic classification of bacterial species. Based on presumed sequence identity among species of the Bacillus cereus sensu lato group, the 16S rRNA genes of B.
