As the throughput of the PacBio Systems continues to increase, so has the desire to fully utilize SMRT Cell sequencing capacity to multiplex microbes for whole genome sequencing. Multiplexing is readily achieved by incorporating a unique barcode for each microbe into the SMRTbell adapters and using a streamlined library preparation process. Incorporating barcodes without PCR amplification prevents the loss of epigenetic information and the generation of chimeric sequences, while eliminating the need to generate separate SMRTbell libraries. We multiplexed the genomes of up to 8 unique strains of H. pylori. Each genome was sheared and processed through adapter ligation in a single, addition-only reaction. The barcoded samples were pooled in equimolar quantities and a single SMRTbell library was prepared. We demonstrate successful de novo microbial assembly from all multiplexes tested (2- through 8-plex) using data generated from a single SMRTbell library, run on a single SMRT Cell with the PacBio RS II, and analyzed with standard SMRT Analysis assembly methods. This strategy was successful using both small (1.6 Mb, H. pylori) and medium (5 Mb, E. coli) genomes. This protocol facilitates the sequencing of multiple microbial genomes in a single run, greatly increasing throughput and reducing costs per genome.
