Introduction: Bacteria are a group of microorganisms which in contrast to their diversity in nature, only very few of them can be grown and isolated in the current standard laboratories. Metagenomics as a new field of research, during the last decade has worked on clarification of the genomes of the non-cultured microbes and researchers around the world with serious study of this group of bacte...
Metagenomics data analyses from independent studies can only be compared if the analysis workflows are described in a harmonized way. In this overview, we have mapped the landscape of data standards available for the description of essential steps in metagenomics: (i) material sampling, (ii) material sequencing, (iii) data analysis, and (iv) data archiving and publishing. Taking examples from m...
The EBI Metagenomics portal The EBI Metagenomics portal [6] is a free to use analysis service for metagenomics data. In order to have your data analysed by EBI Metagenomics, your sequence data have to be archived in the European Nucleotide Archive [7] (ENA). This tutorial will explain why you have to follow this procedure and will then guide you through the process of archiving your metagenomic...
Access to clean water is a grand challenge in the 21st century. Water safety testing for pathogens currently depends on surrogate measures such as fecal indicator bacteria (e.g., E. coli). Metagenomics concerns high-throughput, culture-independent, unbiased shotgun sequencing of DNA from environmental samples that might transform water safety by detecting waterborne pathogens directly instead o...
Metagenomics is a relatively recently established but rapidly expanding field that uses high-throughput next-generation sequencing technologies to characterize the microbial communities inhabiting different ecosystems (including oceans, lakes, soil, tundra, plants and body sites). Metagenomics brings with it a number of challenges, including the management, analysis, storage and sharing of data...
The term 'shotgun metagenomics' is applied to the direct sequencing of DNA extracted from a sample without culture or target-specific amplification or capture. In diagnostic metagenomics, this approach is applied to clinical samples in the hope of detecting and characterizing pathogens. Here, I provide a conceptual overview, before reviewing several recent promising proof-of-principle applicati...

The majority of microbes in many environments are considered " as yet uncultured " and were traditionally considered inaccessible for study through the microbiological gold standard of pure culture. The emergence of metagenomic approaches has allowed researchers to access and study these microbes in a culture-independent manner through DNA sequencing and functional expression of metagenomic DNA...
Metagenomics, the study of genetic material recovered directly from environmental samples, has the potential to provide insight into the structure and function of heterogeneous microbial communities. There has been an increased use of metagenomics to discover and understand the diverse biosynthetic capacities of marine microbes, thereby allowing them to be exploited for industrial, food, and h...
