Whole-genome sequence data and analysis of Lactobacillus delbrueckii subsp. lactis ACA-DC 178 isolated from Greek...

Lactobacillus delbrueckii subsp. lactis is employed in the production of various types of cheese. Here, we report the complete genome sequence of L. lactis ACA-DC 178 isolated from Greek Kasseri cheese. The chromosome of ACA-DC 178 contains 2,050,316 bp with a GC content of 49.6%. A total of 2,112 genes were identified in the genome sequence including 1,752 protein-coding genes, 239 putative pseudogenes, 94 tRNA and 27 rRNA genes. According to the COG annotation, about 80% of the protein-coding genes (1,417 proteins) were assigned to at least one functional category. Approximately the 1/3 of these proteins were distributed among three categories, namely replication, recombination and repair (category L: 10.6%), translation, ribosomal structure and biogenesis (category J: 7.5%) and amino acid transport and metabolism (category E: 7.2%). Fourteen integrated GIs with a total of 159 genes were found in ACA-DC 178 genome. Several of these genes encode proteins associated with exopolysaccharide biosynthesis, amino acid transport and subunits of restriction-modification systems. One large CRISPR array of 3,197 bp containing 52 spacers, several of which are identical to phage sequences having hosts in the genus Lactobacillus, was also identified. The annotated genome sequence of L. lactis ACA-DC 178 is deposited at the European Nucleotide Archive under the accession number LS991409. Raw reads are deposited in the Sequence Read Archive (SRR8866601-3).
