Phylogenomic Analyses

A Gram-stain-positive, aerobic, non-motile and non-spore-forming actinobacterium, designated as F435T, was isolated from soil sample collected from the Cholistan Desert, Pakistan. The taxonomic position of the strain was established by using a polyphasic taxonomic approach. The cells were coccoid-shaped and found in single or arrangement of pairs. The novel strain grew at 15‒37 °C (optimum, 25‒30 °C), pH 7‒11 (optimum, pH 7–8) and in the presence of 0‒8% (w/v) NaCl (optimum, 0 %). Results of blast analysis based on 16S rRNA gene sequences showed that Auraticoccus monumenti MON 2.2T was its closest relative with 97.4 % similarity followed by Desertihabitans aurantiacus CPCC 204711T (95.2 %). In phylogenetic trees, strain F435T formed a robust cluster with the only member of the genus Auraticoccus . The peptidoglycan isomer present in the cell wall was ll-diaminopimelic acid. The major fatty acid was determined to be anteiso-C15 : 0. Characteristic polar lipids of the strain were diphosphatidylglycerol, phosphatidylglycerol, phosphoglycolipids and glycolipids. The predominant menaquinone was MK-9(H4). The genomic G+C content was calculated as 73.5 mol%. The digital DNA–DNA hybridization (GGDC) and average nucleotide identity (ANI) values between strain F435T and A. monumenti MON 2.2T were 24.6 and 81.8 %, respectively. Based on the results of phenotypic, chemotaxonomic, phylogenetic and phylogenomic analyses, strain F435T represents a novel specie of the genus Auraticoccus , for which the name Auraticoccus cholistanensis sp. nov. is proposed. The type strain is F435T (=JCM 33648T=CGMCC 1.17443T). The description of the genus Auraticoccus has also been emended.

Taxonomic Approach

A novel actinobacterium, strain A8036T, isolated from soil, was investigated by using a polyphasic taxonomic approach. The organism formed extensively branched substrate hyphae that generated spiral chains of spores with irregular surfaces. The cell wall contained meso-diaminopimelic acid (type III) and cell-wall sugars were glucose, madurose, mannose and ribose. The predominant menaquinones were MK-9(H6) and MK-9(H4). The phospholipids were diphosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major cellular fatty acids were iso-C16 : 0, C17 : 1 cis9, C16 : 0, C15 : 0 and 10-methyl C17 : 0. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of strain A8036T were Actinomadura meyerae DSM 44715T (99.23 % similarity), Actinomadura bangladeshensis DSM 45347T (98.9 %) and Actinomadura chokoriensis DSM 45346T (98.3 %). However, DNA–DNA relatedness and phenotypic data demonstrated that strain A8036T could be clearly distinguished from the type strains of all closely related Actinomadura species. Strain A8036T is therefore considered to represent a novel species of the genus Actinomadura , for which the name Actinomadura geliboluensis sp. nov. is proposed. The type strain is A8036T ( = DSM 45508T = KCTC 19868T).

Genotypic Characteristics

In this study, the taxonomic position of an actinobacterium, strain YIM M 10931T, which was isolated from a mangrove sediment sample collected in Dugong Creek, Little Andaman, India, was determined by a polyphasic approach. This Gram-positive, aerobic strain produced branched substrate mycelium and aerial hyphae, which differentiated into short, hooked or spiral spore chains. The organism contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The whole cell sugars consisted of mannose, ribose, glucose, galactose and madurose. The cellular fatty acid profile mainly consisted of iso-C16 : 0, 10-methyl C18 : 0 and C16 : 0. The quinone system was predominantly composed of MK-9(H8) (45.5 %) and MK-9(H6) (39 %). The phospholipids detected were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol and two unknown phospholipids. The organism showed a combination of morphological and chemotaxonomic properties typical of members of the genus Actinomadura . Moreover, phylogenetic analysis based on a 16S rRNA gene sequence generated from the strain identified its closest relatives as Actinomadura cremea DSM 43676T (98.4 % sequence similarity), Actinomadura rifamycini DSM 43936T (97.4 %) and Actinomadura apis IM17-1T (96.9 %). It was obvious from the resulting phylogenetic trees that strain YIM M 10931T belongs to a distinct subclade within the evolutionary radiation of the genus Actinomadura . DNA–DNA hybridizations of strain YIM M 10931T with A. cremea DSM 43676T and A. rifamycini DSM 43936T were performed and further confirmed that the isolate represents a separate genomic species. Based on the phenotypic and genotypic characteristics presented, it is proposed that strain YIM M 10931T represents a novel species within the genus Actinomadura , for which the name Actinomadura sediminis sp. nov. is proposed; the type strain is YIM M 10931T ( = CCTCC AA 2010009T = DSM 45500T).
