Respiratory Quinone

A novel thermophilic and endospore-forming Gram-positive bacterium capable of assimilating and isomerizing l-ribose was isolated from a volcanic area in Likupang, Indonesia. The isolate, RI-39T, was able to grow at high temperatures (37–60 °C); optimum growth was observed at pH 6.5 and 45 °C. The strain contained MK-7 (87 %) as the main respiratory quinone and had a DNA G+C content of 51 mol%. The major cellular fatty acids of the isolate were iso-C16 : 0 and anteiso-C15 : 0 and the predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate represents an evolutionary lineage that is distinct from those of other Cohnella species. Based on morphological, physiological and chemotaxonomic characteristics and 16S rRNA gene sequence comparisons, it is proposed that strain RI-39T represents a novel species, Cohnella laeviribosi sp. nov. The type strain is RI-39T (=KCTC 3987T =KCCM 10653PT =CCUG 52217T).

A polyphasic study was carried out to clarify the taxonomic position of two Gram-positive bacteria isolated from soil samples of the Grotta dei Cervi (Italy), a relatively unexplored hypogean environment. The strains, 20-5T and 23-23T, showed phenotypic and phylogenetic characteristics that were consistent with their classification in the genus Agromyces. 16S rRNA gene sequence comparisons revealed that the two strains formed distinct phyletic lines within the genus Agromyces. Based on 16S rRNA gene sequence similarity, chemotaxonomic data and the results of DNA–DNA relatedness studies, it is proposed that the two isolates represent two novel species of the genus Agromyces. Pronounced differences in a broad range of phenotypic characteristics and DNA G+C content distinguished the two strains from each other and from previously described species of the genus Agromyces. Two novel species are proposed: Agromyces salentinus sp. nov. (type strain, 20-5T=HKI 0320T=DSM 16198T=NCIMB 13990T) and Agromyces neolithicus sp. nov. (type strain, 23-23T=HKI 0321T=DSM 16197T=NCIMB 13989T).

Two slightly halophilic bacterial strains, C1-52T and YD-9, were isolated from Daban and Aiding salt lakes in Xinjiang, China, respectively. The isolates were Gram-positive, non-endospore-forming, non-motile, facultatively anaerobic cocci. Colonies were pale yellow, and a light pink, diffusible pigment was produced after a few additional days of incubation. The isolates grew optimally with 2–3 % (w/v) NaCl, at pH 7.5 and at 30–35 °C. The peptidoglycan type was l-Lys–Gly3–4–l-Ala(Gly). The menaquinones were MK-7 (83.2 %) and MK-6 (16.8 %). The major fatty acids (>10 %) were anteiso-C15 : 0 and iso-C15 : 0. The DNA G+C content of strains C1-52T and YD-9 was 41.2 and 41.0 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains C1-52T and YD-9 were closely related to Jeotgalicoccus psychrophilus YKJ-115T (98.0 and 97.1 % 16S rRNA gene sequence similarity, respectively), followed by Jeotgalicoccus halotolerans YKJ-101T (97.1 and 96.8 %). Strains C1-52T and YD-9 shared, respectively, 20 and 11 % DNA–DNA relatedness with J. halotolerans JCM 11198T and 8 and 13 % with J. psychrophilus JCM 11199T. DNA–DNA relatedness between the isolates was 91 %. On the basis of phenotypic and phylogenetic distinctiveness, strains C1-52T and YD-9 belonged to the same species, which should be placed in the genus Jeotgalicoccus as a novel species. The name Jeotgalicoccus halophilus sp. nov. is proposed, with the type strain C1-52T ( = CGMCC 1.8911T  = NBRC 105788T).
