What Metagenomics is and Its Applications in Healthcare and Biotechnology – Magazines Weekly

Metagenomics is simply the study of microbes in the natural living environment that involves complex microbial communities where they exist. The study helps examine an organism’s genomic composition, including all its microbes. Rather than considering the concept of an organism and microbes as separate entities, regard them as a community…

GenomeFace: a deep learning-based metagenome binner trained on 43,000 microbial genomes

Abstract Metagenomic binning, the process of grouping DNA sequences into taxonomic units, is critical for understanding the functions, interactions, and evolutionary dynamics of microbial communities. We propose a deep learning approach to binning using two neural networks, one based on composition and another on environmental abundance, dynamically weighting the contribution…

A Benchmark of Genetic Variant Calling Pipelines Using Metagenomic Short-Read Sequencing

Introduction Short-read metagenomic sequencing is the technique most widely used to explore the natural habitat of millions of bacteria. In comparison with 16S rRNA sequencing, shotgun metagenomic sequencing (MGS) provides sequence information of the whole genomes, which can be used to identify different genes present in an individual bacterium and…

4CAC: 4-class classifier of metagenome contigs using machine learning and assembly graphs

Abstract Microbial communities usually harbor a mix of bacteria, archaea, plasmids, viruses, and microeukaryotes. Within these communities, viruses, plasmids, and microeukaryotes coexist in relatively low abundance, yet they engage in intricate interactions with bacteria. Moreover, viruses and plasmids, as mobile genetic elements, play important roles in horizontal gene transfer and…

Accessing the Soil Metagenome | 4 | Soil Metagenomics

Direct cultivation or indirect molecular approaches can be used to explore and exploit the microbial diversity present in soil. Cultivation and isolation of microorganisms is the traditional method but, as only 0.1% to 1.0% of the soil bacteria are culturable using standard cultivation methods. Methods described for metagenomic DNA isolation…

Metagenome profiling and containment estimation through abundance-corrected k-mer sketching with sylph

Profiling metagenomes against databases allows for the detection and quantification of microbes, even at low abundances where assembly is not possible. We introduce sylph, a metagenome profiler that estimates metagenome-genome average nucleotide identity (ANI) through zero-inflated Poisson k-mer statistics, enabling ANI-based taxa detection. Sylph is the most accurate method on…
