Sequencing of single bacterial and archaeal cells is an important methodology that provides access to the genetic makeup of uncultivated microorganisms. We here describe the high-throughput fluorescence-activated cell sorting-based isolation of single cells from the environment, their lysis and strand displacement-mediated whole genome amplification. We further outline 16S rRNA gene sequence-based screening of single-cell amplification products, their preparation for Illumina sequencing libraries, and finally propose computational methods for read and contig level quality control of the resulting sequence data.
