Whole-genome sequencing of Lactococcus lactis non-dairy strain: DPC 6756
The genomic DNA was isolated from overnight cultures grown at 30C in M-17 broth (Sigma-Aldrich) using the UltraClean microbial DNA isolation kit (Mo Bio Laboratories, Cambridge, UK) following manufacturer's instructions. Genomic libraries were prepared with a Nextera XT DNA library preparation kit (Illumina, Inc., San Diego, CA, USA). The 250-bp paired read sequencing was performed on an Illumina HiSeq 2500 platform (MicrobesNG, University of Birmingham, UK)
