Abstract

Here we report complete genome sequence of Gram-positive, rod-shaped and chemoheterophic Lactobacillus paraplantarum strain CK401 with anti-avian flu activity. Circular chromosome of 3,164,408 bp with 43.99% G + C content and five circular plasmids: pCK401A (15,102 bp with 37.33% G + C content), pCK401B (15,825 bp with 40.58% G + C content), pCK401C (12,380 bp with 36.03% G + C content), pCK401D (40,656 bp with 42.00% G + C content), and pCK401E (41,380 bp with 40.12% G + C content). Total genes of 3,179 in number were predicted: 3,088 are protein coding genes and 2,061 of protein coding genes could be functionally assigned. The chromosome harbors 5 operons of 16 rRNAs and 71 tRNA genes. No CRISPR locus was found in this genome. Canonical glycoylitic and pentose phosphate pathways plus lactate/alcohol/ butanediol dehydrogenases and acetate kinase suggested that the strain may have a heteroferementative metabolism. Diverse glycosyl hydrolases (GH) were endcoded in 47 genes in 17 GH families: alpha-amylases, alpha-/beta-galactosidases, beta-glucosidases, a beta-glucuronidase, a galactanase, and an invertase.
Some bacteriocin genes and confirmed hyaluronic acid gene showed that the antibiotic-resistance-free strain CK401 will be a promising probiotic candidates for animals.
