Complete and Assembled Genome Sequence of Lactobacillus plantarum RI-113 Isolated from Salami.

We present here the complete genome sequence of Lactobacillus plantarum RI-113, a strain isolated from salami, which was determined using single-molecule real-time sequencing.

GENOME ANNOUNCEMENT

Lactobacillus plantarum strains have been isolated from a broad spectrum of ecosystems such as silage, olives, sourdough, sauerkraut, cheese, and fermented sausages (1, 2). This habitat diversity of L. plantarum might be related to abundant gene functions resulting in a genome size which is one of the largest among lactobacilli (3, 4). L. plantarum RI-113 is a single-colony strain isolated from salami that grows at a pH of 3.5, 7.5% NaCl, and 5% ethanol at a temperature range of 14°C to 43°C in Man-Rogosa-Sharpe medium. The strain shows antifungal activity against Trichosporon sp. and Rhodotorula mucilaginosa, as detected in a high-throughput screening (5). Genomic DNA was isolated by first using lysozyme-based cell-wall digestion with a Wizard genomic DNA purification kit (Promega, Dübendorf, Switzerland). The genome was sequenced using single–molecule real-time sequencing cells on a PacBio RS II platform (Pacific Biosciences, Menlo Park, CA, USA) at the Functional Genomics Center Zurich (Zurich, Switzerland). In total, 94,382 reads, with a mean length of 12,974 bp resulting in 370× coverage, were assembled into a single contig and six plasmids using the Hierarchical Genome Assembly Process (6). The genome was automatically annotated using the NCBI Prokaryotic Genome Annotation Pipeline. The genome of L. plantarum RI-113 consists of a 3,462,990-bp circular molecule and comprises 67 tRNA genes and 16 rRNA genes. The G+C content of the genome is 44.34%, and a total of 3,361 protein-coding sequences were predicted.
