Roseomonas coralli sp. nov., a heavy metal resistant bacterium isolated from coral

Abstract

A Gram-stain-negative, aerobic, mesophilic, non-motile bacterium, designated M0104T, was isolated from a gorgonian coral collected from Xieyang island, Guangxi Province, PR China. Colonies of the strain were non-motile cocci and pink. The strain grew at 15–34 °C (optimum, 28 °C), pH 4.5–8.0 (optimum, pH 7.0) and with 0–4% (w/v) NaCl (optimum, 0–2 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain M0104T was closely related to Roseomonas deserti JCM 31275T (96.2 %), Roseomonas vastitatis KCTC 62043T (96.0 %), Roseomonas aerofrigidensis JCM 31878T (95.9 %) and Roseomonas oryzae KCTC 42542T (95.7 %). The strain had an assembly size of 5.0 Mb and a G+C content of 71.0mol%. Genes involved in copper, cadmium, lead, arsenic and zinc resistance were identified in the genome of strain M0104T. The digital DNA–DNA hybridization and average nucleotide identity values between the genome sequence of strain M0104T and those of closely related type strains were 19.4–24.9 % and 74.3–81.8 %, respectively. Strain M0104T contained C18:1 ω7c, C18:3 ω3c, anteiso C11:0 and C16:0 as the major fatty acids (>7 %) and ubiquinone Q-10 as the sole isoprenoid quinone. Diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine were its major polar lipids. Based on its phenotypic, phylogenetic and chemotaxonomic properties, strain M0104T is proposed to represent a novel species within the genus Roseomonas , for which the name Roseomonas coralli sp. nov. is proposed. The type strain is M0104T (=KCTC 62359T=MCCC 1K03632T).

Phylotaxogenomics for the Reappraisal of the Genus Roseomonas With the Creation of Six New Genera

“…Basonym: Roseomonas coralli (Li et al, 2021) The description is the same as that of Roseomonas coralli as given by Li et al (2021). MN336179 is the accession number for the 16S rRNA gene sequence and SNVJ000000000 for the genome sequence.…”

Biogeographic patterns of potential pathogenic bacteria in the middle and lower reaches of the Yangtze River as well as its two adjoining lakes, China

“…These bacteria are intracellular pathogens of freshwater protozoa and utilize the same mechanism to invade human phagocytic cells, thus causing severe Legionnaires' disease (Fields et al, 2002;Kenagy et al, 2017). The genus Roseomonas has been frequently isolated from environment samples, such as drinking water, freshwater and marine invertebrates (Zhang et al, 2020;Li et al, 2021;Yin et al, 2021). Although the transmission route of Roseomonas infections is unclear, it's theorized that an infection could occur through contaminated water, and cause a disease, such as a bacteremia in immunocompromised individuals (Ioannou et al, 2020).…”

Acuticoccus mangrovi sp. nov., with an antibacterial property, isolated from mangrove sediment

“… Proteobacteria is the most abundant phylum in marine pelagic systems and the Beibu Gulf mangrove ecosystem [4, 5]. Member of this phylum exhibit a wide range of biological properties, such as aerobic anoxygenic photosynthesis, degradation of aromatic compounds, reduction of heavy metals and production of bioactive secondary metabolites [6–9]. In the present study, 45 Proteobacteria -like bacteria were obtained from mangrove sediments from Beibu Gulf, South China Sea (Fig.…”
