A new Lb. plantarum strain DY46 was isolated from a traditionally fermented non-alcoholic beverage called shalgam from the Southern region of Anatolia following incubation on MRS agar at 30°C for 5 days. DY46 is gram-positive, short rod and catalase-negative. This bacterium fermented 22 of the 49 substrates tested on API CH50 fermentation panels. Whole-genome sequencing was performed using the Illumina Miseq platform to learn more about the metabolic capabilities of DY46. The sequences were assembled into a 3.32 Mb draft genome using PATRIC 3.6.8. consisting of 153 contigs, and preliminary genome annotation was performed using the RAST algorithm. The DY46 genome consists of a single circular chromosome of 3,332,827 bp that is predicted to carry 3219 genes, including 61 tRNA genes, 2 rRNA operons. The genome has a GC content of 44.3% includes 98 predicted pseudogenes, 25 complete or partial transposases and 3 intact prophages. DY46 genome also predicted to carry genes of Plantaricin-E, Plantaricin-F and Plantaricin-K showing the antimicrobial potential of this bacterium which can be linked-to in vitro antagonism tests that DY46 can inhibit Salmonella Typimirium ATCC14028, Klebsiella pneumonie ATCC13883, and Proteus vulgaris ATCC8427. The acid and bile tolerance of DY46 revealed this strain could potentially pass through the stomach and reach into the gut to provide probiotic therapeutic affects on health.
