Freshwater Spring

A Gram-stain-negative, non-spore-forming, non-flagellated, rod-shaped bacterial strain, SSK2-1T, was isolated from the zone where the ocean and a freshwater spring meet at Jeju island, South Korea, and subjected to a polyphasic taxonomic study. Strain SSK2-1T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain SSK2-1T clustered with the type strains of two Octadecabacter species, showing 96.5–96.8 % 16S rRNA gene sequence similarity. Strain SSK2-1T and Octadecabacter arcticus DSM 13978T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the common major fatty acid. The polar lipid profile of strain SSK2-1T was similar to that of O. arcticus DSM 13978T by having phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid as the major components. The DNA G+C content of strain SSK2-1T was 60.1 mol%. Differential phenotypic properties, particularly temperature range for growth, oxidase activity and nitrate reduction, together with phylogenetic distinctiveness, revealed that strain SSK2-1T is separate from recognized species of the genus Octadecabacter . On the basis of the data presented, strain SSK2-1T is considered to represent a novel species of the genus Octadecabacter , for which the name Octadecabacter jejudonensis sp. nov. is proposed. The type strain is SSK2-1T ( = KCTC 32535T = CECT 8397T).

Strain SB026T was isolated from Brazilian rainforest soil and its taxonomic position established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological features consistent with its classification in the genus Amycolatopsis and formed a branch in the Amycolatopsis 16S rRNA gene tree together with Amycolatopsis bullii NRRL B-24847T, Amycolatopsis plumensis NRRL B-24324T, Amycolatopsis tolypomycina DSM 44544T and Amycolatopsis vancoresmycina NRRL B-24208T. It was related most closely to A. bullii NRRL B-24847T (99.0 % 16S rRNA gene sequence similarity), but was distinguished from this strain by a low level of DNA–DNA relatedness (~46 %) and discriminatory phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the isolate should be classified in the genus Amycolatopsis as representing a novel species, Amycolatopsis rhabdoformis sp. nov. The type strain is SB026T ( = CBMAI 1694T = CMAA 1285T = NCIMB 14900T).

A novel Gram-negative, aerobic, catalase- and oxidase-positive, non-sporulating, non-motile, rod-shaped bacterium, designated strain UST081027-248T, was isolated from seawater of the Red Sea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain UST081027-248T fell within the genus Erythrobacter . Levels of 16S rRNA gene sequence similarity between the novel strain and the type strains of Erythrobacter species ranged from 95.3 % (with Erythrobacter gangjinensis ) to 98.2 % (with Erythrobacter citreus ). However, levels of DNA–DNA relatedness between strain UST081027-248T and the type strains of closely related species were below 70 %. Optimal growth of the isolate occurred in the presence of 2.0 % NaCl, at pH 8.0–9.0 and at 28–36 °C. The isolate did not produce bacteriochlorophyll a. The predominant cellular fatty acids were C17 : 1ω6c, summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) and C15 : 0 2-OH. The genomic DNA G+C content of strain UST081027-248T was 60.4 mol%. Phenotypic properties and phylogenetic distinctiveness clearly indicated that strain UST081027-248T represents a novel species of the genus Erythrobacter , for which the name Erythrobacter pelagi sp. nov. is proposed. The type strain is UST081027-248T ( = JCM 17468T = NRRL 59511T).

A Gram-negative, non-motile, non-spore-forming bacterial strain, PR1T, was isolated from a mud core sample containing colonial choanoflagellates near Hog Island, Virginia, USA. Strain PR1T grew optimally at 30 °C and with 3 % (w/v) NaCl. Strain PR1T contained MK-7 as the major menaquinone as well as carotenoids but lacked pigments of the flexirubin-type. The predominant fatty acids were iso-C15 : 0 (29.4 %), iso-C17 : 1ω9c (18.5 %) and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c; 11.3 %). The major polar lipids detected in strain PR1T were phosphatidylethanolamine, an unknown phospholipid, an aminophospholipid, an aminolipid and two lipids of unknown character. The DNA G+C content was 38.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain PR1T fell within the cluster comprising the genus Algoriphagus and was most closely related to Algoriphagus halophilus JC 2051T (95.4 % sequence similarity) and Algoriphagus lutimaris S1-3T (95.3 % sequence similarity). The 16S rRNA gene sequence similarity between strain PR1T and the type strains of other species of the genus Algoriphagus were in the range 91–95 %. Differential phenotypic properties and phylogenetic and genetic distinctiveness of strain PR1T demonstrated that this strain was distinct from other members of the genus Algoriphagus , including its closest relative, A. halophilus . Based on phenotypic, chemotaxonomic, phylogenetic and genomic data, strain PR1T should be placed in the genus Algoriphagus as a representative of a novel species, for which the name Algoriphagus machipongonensis sp. nov. is proposed. The type strain is PR1T ( = ATCC BAA-2233T  = DSM 24695T).

A Gram-stain-negative, rod-shaped bacterial strain, designated SW123T, was isolated from a deep-sea water sample collected from the Indian Ocean. Strain SW123T was strictly aerobic, catalase- and oxidase-positive. The predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 and summed feature 9 (comprising C16 : 0-methyl or iso-C17 : 1 ω9c). Ubiquinone-8 was the sole respiratory quinone. The major polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content was 49.4 mol%. 16S rRNA gene sequence analysis showed that strain SW123T was closely related to Aliidiomarina shirensis AIST (96.7 % sequence similarity), Aliidiomarina iranensis GBPy7T (96.3%), Aliidiomarina haloalkalitolerans AK5T (96.0%) and Aliidiomarina celeris F3105T (95.9%). Phylogenetic trees based on 16S rRNA gene sequences showed that strain SW123T represented a novel member of the genus Aliidiomarina , forming a distinct cluster with A. celeris F3105T. On the basis of phylogenetic inference and phenotypic characteristics, we propose that strain SW123T represents a novel species of the genus Aliidiomarina , with the name Aliidiomarina indica sp. nov. The type strain is SW123T (=CGMCC1.16169T=KCTC 82234T).
