Draft Genome Sequence of Calcium-Dependent Novosphingobium sp. Strain TCA1, Isolated from a Hot Spring Containing a High Concentration of Calcium Ions.

ABSTRACT: Calcium-dependent Novosphingobium sp. strain TCA1 was newly isolated from a water sample from a hot spring containing a high concentration of calcium ions. Here, we report the draft genome sequence of this bacterium, which may be the basis for research on calcium ion homeostasis.

Project description:A polyphasic study was designed to resolve the taxonomic position of isolate MGRD01-02T which was recovered from an acidic hot spring in Indonesia and assigned to the genus Actinospica. Phylogenetic analyses based on 16S rRNA gene sequences show that the isolate is most closely related to the type strains of Actinospica acidiphila (98.5%), Actinospica robiniae (97.8%) and Actinospica durhamensis (96.8%). Morphological and chemotaxonomic data underpin the assignment of the isolate to the genus Actinospica as it forms an extensively branched substrate mycelium which carries tufts of white aerial hyphae that differentiate into straight to flexuous chains of cylindrical spores with faint rugose surfaces, contains 2,6-diamino-3-hydroxydiaminopimelic acid in the peptidoglycan, mixtures of hydrogenated menaquinones with nine isoprene units, iso-C 15:O and iso-C 16:O as major fatty acids and phosphatidylethanolamine as the diagnostic phospholipid. Whole-genome sequence analyses show that the isolate, A. durhamensis CSCA 57T and Actinocrinis puniceicyclus DSM 45168T have genome sizes of 7.9, 9.6 and 6.7 Mbp, respectively. A phylogenomic tree shows that they form distinct branches in a well-supported clade, a result supported by associated phenotypic data. Average nucleotide identity and digital DNA:DNA hybridization similarities are below the recommended thresholds for assigning strains to the same species; they also indicate that isolate MGRD01-02T is most closely related to the A. durhamensis and A. robiniae strains. Corresponding amino acid identity and conserved protein data not only support these relationships but also confirm the taxonomic integrity of the genus Actinocrinis. Based on these results, it is proposed that isolate MGRD01-02T (= CCMM B1308T = ICEBB-09T = NCIMB 15218T) be classified in the genus Actinospica as Actinospica acidithermotolerans sp. nov. The draft genome of the isolate and its closest phylogenomic neighbours contain biosynthetic gene clusters with the potential to produce new natural products, notably antibiotics.
