Metagenomic Assembly: Reconstructing Genomes from Metagenomes.

Assembly of metagenomic sequence data into microbial genomes is of critical importance for disentangling community complexity and unraveling the functional capacity of microorganisms. The rapid development of sequencing technology and novel assembly algorithms have made it possible to reliably reconstruct hundreds to thousands of microbial genomes from raw sequencing reads through metagenomic assembly. In this chapter, we introduce a routinely used metagenomic assembly workflow including read quality filtering, assembly, contig/scaffold binning, and postassembly check for genome completeness and contamination. We also describe a case study to reconstruct near-complete microbial genomes from metagenomes using our workflow.
