TLDR
The UPARSE pipeline reports operational taxonomic unit (OTU) sequences with ≤1% incorrect bases in artificial microbial community tests, compared with >3% correct bases commonly reported by other methods.
Abstract
Amplified marker-gene sequences can be used to understand microbial community structure, but they suffer from a high level of sequencing and amplification artifacts. The UPARSE pipeline reports operational taxonomic unit (OTU) sequences with ≤1% incorrect bases in artificial microbial community tests, compared with >3% incorrect bases commonly reported by other methods. The improved accuracy results in far fewer OTUs, consistently closer to the expected number of species in a community.

Introducing BASE: the Biomes of Australian Soil Environments soil microbial diversity database

TL;DR: The ‘Biomes of Australian Soil Environments’ (BASE) project has generated a database of microbial diversity with associated metadata across extensive environmental gradients at continental scale, becoming the first Australian soil microbial diversity database.

A comparison of sequencing platforms and bioinformatics pipelines for compositional analysis of the gut microbiome

TL;DR: The three platforms compared were capable of discriminating samples by treatment, despite differences in diversity and abundance, leading to similar biological conclusions, demonstrating that while there were differences in depth of coverage and phylogenetic diversity, all workflows revealed comparable treatment effects on microbial diversity.

Synthetic microbiota reveal priority effects and keystone strains in the Arabidopsis phyllosphere

TL;DR: The authors identify several keystone strains and show that priority effects drive phyllosphere community assembly, and indicate that individual strains of Proteobacteria and Actinobacteria have the greatest potential to affect community structure as keystone species.

Mechanism and Effect of Temperature on Variations in Antibiotic Resistance Genes during Anaerobic Digestion of Dairy Manure.

TL;DR: The bacterial community succession was the dominant mechanism that influenced the variation in ARGs and integrons during anaerobic digestion and Thermophilic an aerobic digestion is recommended for the treatment and reuse of animal manure.

Search and clustering orders of magnitude faster than BLAST

Robert C. Edgar
- 01 Oct 2010 - 
TL;DR: UCLUST is a new clustering method that exploits USEARCH to assign sequences to clusters and offers several advantages over the widely used program CD-HIT, including higher speed, lower memory use, improved sensitivity, clustering at lower identities and classification of much larger datasets.

UCHIME improves sensitivity and speed of chimera detection

TL;DR: UCHIME has better sensitivity than ChimeraSlayer (previously the most sensitive database method), especially with short, noisy sequences, and in testing on artificial bacterial communities with known composition, UCHIME de novo sensitivity is shown to be comparable to Perseus.

Database resources of the National Center for Biotechnology Information

TL;DR: In addition to maintaining the GenBank(R) nucleic acid sequence database, the National Center for Biotechnology Information (NCBI) provides data analysis and retrieval resources for the data in GenBank and other biological data made available through NCBI’s website.
