Abstract

Strain 6021052837T was isolated from the blood culture of a hemodialysis patient on Chocolat PolyViteX medium at 37 °C after 2 days of incubation. Colonies could not be identified by our systematic MALDI-TOF Mass Spectrometry screening. The16S rRNA gene sequencing showed that the strain had 96% sequence identity with Cohnella formosensis (Genbank accession number JN806384), the phylogenetic closely related type strain of a species with standing in nomenclature, which putatively classifies it as a new species. The colonies cultivated on Columbia agar with 5% sheep blood medium at 37 °C after 24 h of incubation, are white pigmented, their size varied from 1.5 to 2 mm in diameter. Strain 6021052837T is an aerobic, Gram-negative, motile, spore forming rod, which cannot grow microaerophilically or under anaerobic conditions. The major fatty acids are branched saturated fatty acids: 14-methyl-pentadecanoic acid (34%) and 12-methyl-tetradecanoic acid (31%). The 6.328 Mb long genome, composed of 25 contigs, has a G+C content of 57.24%. Out of the 5710 predicted genes, 5646 were protein-coding genes and 64 were RNAs. A total of 3239 genes (57.37%) were assigned as putative function (by COGs) and 288 genes were identified as ORFans (5.1%). Average genomic identity of orthologous gene sequences (AGIOS) of strain 6021052837T against genomes of the type strains of related species ranged between 58.26 and 79.63%, respectively. According to our taxonogenomics results, we propose the creation of Cohnella massiliensis sp. nov. that contains the type strain 6021052837T (= CSUR P2659, =DSM103435).
