An actinobacterial strain was isolated from marine sediment taken from the Troitsa Bay of the Gulf of Peter the Great, East Siberian Sea, and subjected to a taxonomic investigation. The isolate, designated KMM 3905T, was Gram-positive, aerobic, non-motile and coccoid. The strain tolerated up to 15 % NaCl in growth media, although its presence was not essential for growth. Chemotaxonomic and phylogenetic properties of the strain were consistent with its classification in the genus Kocuria. The strain formed an independent phylogenetic line in the 16S rRNA gene tree encompassed by members of Kocuria. Comparison of phenotypic characteristics also supported its assignment to a novel species within Kocuria. The name Kocuria marina sp. nov. (type strain KMM 3905T=KCTC 9943T) is proposed for this halotolerant actinobacterium from the marine environment.

The 16S Rrna Gene

Resequencing of the 16S rRNA gene of the type strain of Herbaspirillum putei Ding and Yokota 2004 revealed 99.9 % sequence similarity to that of the type strain of Herbaspirillum huttiense (Leifson 1962) Ding and Yokota 2004. This high phylogenetic relatedness of H. putei and H. huttiense was confirmed by the results of DNA–DNA hybridization between H. huttiense DSM 10281T and H. putei ATCC BAA-806T (reassociation value 96 %). Therefore, it is proposed to reclassify the type strain of H. putei as a strain of H. huttiense. However, the genome of the type strain of H. putei is about 0.9 Mb larger than that of the H. huttiense type strain. This results in a decrease in the reassociation value in the reciprocal DNA–DNA hybridization to 72 %, a level slightly above the threshold for delineating bacterial species. These data and distinctive phenotypic characteristics indicate that the name Herbaspirillum putei is a later heterotypic synonym of Herbaspirillum huttiense and permit the description of two novel subspecies, Herbaspirillum huttiense subsp. huttiense subsp. nov. (type strain ATCC 14670T =JCM 21423T =DSM 10281T) and Herbaspirillum huttiense subsp. putei subsp. nov., comb. nov. (type strain 7-2T =JCM 21495T =ATCC BAA-806T). Three bacterial strains, IEH 4430T, IEH 4515 and IEH 8757, isolated from water were found to be the closest relatives of these strains. Strain IEH 8757 was classified as a strain of H. huttiense subsp. putei. Studies of genotypic and phenotypic features of strains IEH 4430T and IEH 4515 showed that the strains represent a novel species, which is most closely related to H. huttiense and for which the name Herbaspirillum aquaticum sp. nov. is proposed (type strain IEH 4430T =DSM 21191T =ATCC BAA-1628T).

The taxonomic status of ‘Actinoplanes liguriae’ A/6353 and ‘Actinoplanes teichomyceticus’ AB8327 was established by using a polyphasic approach. Strains A/6353 and AB8327 form distinct phylogenetic lineages in the 16S rRNA gene tree of members of the genus Actinoplanes and are related moderately and closely to Actinoplanes rectilineatus and Actinoplanes cyaneus, respectively. Morphological, cultural and physiological properties indicated that strains A/6353 and AB8327 represent separate, novel species of the genus Actinoplanes, Actinoplanes liguriensis sp. nov. (type strain A/6353T=FH 2244T=DSM 43865T=ATCC 31048T=BCRC 12121T=CBS 355.75T=IMSNU 22127T=JCM 3250T=KCTC 9536T=KCC A-0250T=NBRC 13997T=NCIMB 12636T=NRRL B-16723T=SANK 62178T) and Actinoplanes teichomyceticus sp. nov.

Strain DCY45T was isolated from soil of a ginseng field in Pocheon Province, Korea. Strain DCY45T was Gram-negative, oxidase- and catalase-positive, motile and rod-shaped and produced yellow pigments on R2A agar. The organism grew optimally at 30 °C and at pH 7.0. The G+C content of the genomic DNA was 65.4 mol%. The predominant respiratory quinone was Q-8. The major fatty acids were iso-C17 : 1 ω9c, iso-C16 : 0 and iso-C15 : 0. Phylogenetic analysis based on the 16S rRNA gene sequence was used to determine the taxonomic position of strain DCY45T, which is most closely related to species of the genus Rhodanobacter, with similarity levels of 96.0–98.4 %; DNA–DNA relatedness with related strains was lower than 60 %. Strain DCY45T differed significantly from related type strains in phenotypic characteristics. On the basis of these phenotypic, genotypic and chemotaxonomic studies, strain DCY45T represents a novel species of the genus Rhodanobacter, for which the name Rhodanobacter soli sp. nov. is proposed. The type strain is DCY45T (=KCTC 22620T =JCM 16126T).

A novel thermophilic, strictly anaerobic, chemo-organotrophic bacterium, designated MCT, was isolated from a geothermally heated sediment of a marine hydrothermal system at Palaeochory Bay, Milos, Greece. Cells of strain MCT were rods of variable length (4–12 μm) and width (0.2–0.3 μm), occurring as single cells or forming large aggregates that were visible as flocs. Strain MCT grew optimally at pH 7.0 and 60 °C and with 3 % (w/v) NaCl. Strain MCT grew chemo-organoheterotrophically and fermented peptides and di- and polysaccharides in the presence of 0.1 g yeast extract l−1. The DNA G+C content of strain MCT was 43.3 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed strain MCT within the genus Caldithrix. However, strain MCT possessed certain phenotypic features that differentiated it from the type strain of the only species of the genus Caldithrix described to date. On the basis of phylogenetic and phenotypic characteristics, it is proposed that strain MCT represents a novel species, Caldithrix palaeochoryensis sp. nov. The type strain is MCT (=DSM 21940T =VKM B-2536T). In addition, an emended description of the genus Caldithrix is presented.

A Gram-stain-positive, endospore-forming, rod-shaped bacterium, designated XJ259T, was isolated from a cold spring sample from Xinjiang Uyghur Autonomous Region, China. The isolate grew optimally at 20–30 °C and pH 7.3–7.8. Comparative analysis of the 16S rRNA gene sequence showed that isolate XJ259T belonged phylogenetically to the genus Paenibacillus, and was most closely related to Paenibacillus xinjiangensis B538T (with 96.6 % sequence similarity), Paenibacillus glycanilyticus DS-1T (96.3 %) and Paenibacillus castaneae Ch-32T (96.1 %), sharing less than 96.0 % sequence similarity with all other members of the genus Paenibacillus. Chemotaxonomic analysis revealing menaquinone-7 (MK-7) as the major isoprenoid quinone, diphosphatidylglycerol, phosphatidylethanolamine and two unknown phosphoglycolipids as the major cellular polar lipids, a DNA G+C content of 47.0 mol%, and anteiso-C15 : 0 and C16 : 0 as the major fatty acids supported affiliation of the new isolate to the genus Paenibacillus. Based on these data, isolate XJ259T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus algorifonticola sp. nov. is proposed. The type strain is XJ259T ( = CGMCC 1.10223T  = JCM 16598T).

Abstract A Gram-stain-negative, gliding-motile, positive for catalase, facultative anaerobic, designated strain XSD401T, was isolated from the red algae of Xiaoshi Island, Shandong Province, China. Growth occurred at 20–37 °C (optimum, 33 °C), pH 5.5–9.5 (optimum, pH 6.5–7.5), and with 0.5–5% (w/v) NaCl (optimum, 3%). The main fatty acids are iso-C15:0, iso-C15:1 G, iso-C17:0 3-OH, iso-C15:0 3-OH, C16:0. Phosphatidylethanolamine (PE), three unidentified aminolipids (AL1, AL2, AL3) and one unidentified lipid (L) were the major polar lipids. The G+C content of the genomic DNA was 33.9 mol%. Strain XSD401T had the highest sequence similarity (96.88%) to the 16S rRNA gene of Psychroserpens damuponensis KCTC 23539T. The similarities with Psychroserpens burtonensis DSM 12212T was 96.31%. The dDDH values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T, were 20.40% and 20.30%, respectively. The average nucleotide identity (ANI) values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T were 76.91%, 76.88%, respectively. The differences in morphology, physiology and genotype from the previously described taxa support the classification of strain XSD401T as a representative of a novel species of the genus Psychroserpens, for which the name Psychroserpens luteus sp. nov. is proposed. The type strain is XSD401T (= MCCC 1H00396T = KCTC 72684T = JCM 33931T).

Three novel endophytic strains, designated 17B10-2-12T, 26C10-4-4 and D13-10-4-9, were isolated from the bark of Populus euramericana in Heze, Shandong Province, China. They were Gram-reaction-negative, aerobic, non-motile, short-rod-shaped, oxidase-positive and catalase-negative. A phylogenetic analysis of the 16S rRNA gene showed that the three novel strains clustered with members of the family Comamonadaceae and formed a distinct branch. The isolates shared 100 % similarities among themselves and had the highest sequence similarity with Xenophilus azovorans DSM 13620T (95.2 %) and Xenophilus arseniciresistens YW8T (95.0 %), and less than 95.0 % sequence similarities with members of other species. Their major fatty acids were C16 : 0, C17 : 0 cyclo, C18 : 1ω7c and C16 : 1ω7c/C16 : 1ω6c. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and three unknown aminophospholipids. The predominant quinone was ubiquinone-8 (Q-8). The DNA G+C content was 69.5–70.0 mol%. Based on data from a polyphasic taxonomy study, the three strains represent a novel species of a novel genus of the family Comamonadaceae, for which the name Corticibacter populi gen. nov., sp. nov. is proposed. The type strain is 17B10-2-12T ( = CFCC 12099T = KCTC 42091T).
