A novel aerobic actinomycete, designated HA11110T, was isolated from a mangrove soil sample collected in Haikou, China. It formed white aerial mycelium and pale yellow substrate mycelium on Gause's synthetic agar no. 1. Scanning electron microscopy revealed that cells of HA11110T produced straight to spiral spore chains with spiny spores. Chemotaxonomic tests showed that the cell wall contained ll-diaminopimelic acid and the major fatty acids were iso-C16 : 0, anteiso-C15 : 0 and iso-C14 : 0.16S rRNA gene sequence similarity showed that strain HA11110T belonged to the genus Streptomyces, most closely related to Streptomyces fenghuangensis GIMN4.003T (99.1 %), Streptomyces nanhaiensis SCSIO 01248T (98.8 %) and Streptomyces radiopugnans R97T (98.8 %). However, DNA–DNA hybridization studies of strain HA11110T with these three closest relatives showed relatedness values of 58.4, 49.7 and 47.2 %, respectively. On the basis of phenotypic and genotypic data, strain HA11110T represents a novel species of the genus Streptomyces, for which the name Streptomyces mangrovi sp. nov. is proposed. The type strain is HA11110T ( = CGMCC 4.7117T = DSM 42113T).

A novel actinomycete, designated HM 537T, was isolated from soil in Hamedan Province, Iran. Cell-wall hydrolysates of strain HM 537T contained meso-diaminopimelic acid, and whole-cell hydrolysates contained ribose, glucose, galactose, rhamnose and traces of mannose. The main phospholipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol and an unknown phospholipid. MK-9(H4), an unknown MK and MK-10(H4) were the predominant menaquinones. The major fatty acids included iso-C16 : 0, iso-C15 : 0, iso-C16 : 1 G and 9(?)-methyl C16 : 0. Strain HM 537T had the highest 16S rRNA gene sequence similarity to Saccharothrix hoggarensis DSM 45457T (99.5 %) and Saccharothrix saharensis DSM 45456T (99.0 %). DNA–DNA hybridization studies showed relatedness values of 13.8 ± 3.3 % with S. hoggarensis DSM 45457T and 16.3 ± 3.5 % with S. saharensis DSM 45456T. Based on the results of phenotypic and genotypic studies, strain HM 537T represents a novel species of the genus Saccharothrix, for which the name Saccharothrix ecbatanensis sp. nov. is proposed. The type strain is HM 537T ( = DSM 45486T = UTMC 00537T = CCUG 63021T).

Two novel species belonging to the genus Shewanella are described on the basis of a polyphasic taxonomic approach. A total of 40 strains of Gram-negative, psychrotolerant, H2S-producing bacteria were isolated from marine fish (cod and plaice) caught in the Baltic Sea off Denmark. Strains belonging to group 1 (seven strains) were a lactate-assimilating variant of Shewanella morhuae with a G+C content of 44 mol%. The strains of group 2 (33 strains) utilized lactate, N-acetylglucosamine and malate but did not produce DNase or ornithine decarboxylase. Their G+C content was 47 mol%. Phylogenetic analysis of the 16S rRNA gene sequence data placed the two novel species within the genus Shewanella. Group 1 showed greatest sequence similarity with S. morhuae ATCC BAA-1205T (99.9 %). However, gyrB gene sequence analysis and DNA–DNA hybridization differentiated these isolates from S. morhuae, with 95.6 % sequence similarity and less than 57 % DNA relatedness, respectively. Group 2 strains shared more than 99 % 16S rRNA gene sequence similarity with the type strains of Shewanella colwelliana and Shewanella affinis, but gyrB sequence similarity (~85 %) and the results of DNA hybridization (~28 %) indicated that the new isolates represented a novel species. Furthermore, when compared to each other, the type strains of S. colwelliana and S. affinis had almost identical gyrB sequences and significantly high DNA reassociation values (76–83 %), indicating that they belonged to the same species. Based on the conclusions of this study, we propose the novel species Shewanella glacialipiscicola sp. nov. (type strain T147T=LMG 23744T=NBRC 102030T) for group 1 strains and Shewanella algidipiscicola sp. nov. (type strain S13T=LMG 23746T=NBRC 102032T) for group 2 strains, and we propose that Shewanella affinis as a later heterotypic synonym of Shewanella colwelliana.

A novel, Gram-positive, non-motile, endospore-forming and moderately halophilic bacterium, strain GrbiT, was isolated from a traditional Korean fermented seafood. The organism grew optimally in the presence of 10–15 % NaCl, at 37 °C and pH 8.0. The peptidoglycan of the cell wall consisted of meso-diaminopimelic acid, and the predominant menaquinone was MK-7. The major fatty acids of strain GrbiT were iso-C16 : 0 (36.4 %), anteiso-C15 : 0 (30.3 %) and iso-C14 : 0 (18.2 %). The polar lipids were phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid. The genomic DNA G+C content was 42.5 mol%. Strain GrbiT was most closely related to the type strain Lentibacillus kapialis JCM 12580T, with which it shared 97.5 % 16S rRNA gene sequence similarity. The DNA–DNA hybridization value between strains GrbiT and L. kapialis JCM 12580T was 8 %. Based on phenotypic, genotypic and phylogenetic data, strain GrbiT should be classified as a novel species within the genus Lentibacillus, for which the name Lentibacillus jeotgali sp. nov. is proposed. The type strain is GrbiT (=KCTC 13300T=JCM 15795T).

Two coryneform bacteria were isolated from a penguin rookery soil sample collected in Antarctica, near the Indian station Dakshin Gangotri (strain Lz1yT), and from sea water from Kerguelen island, Antarctica (strain KGN15T). They have morphological and chemotaxonomic properties (peptidoglycan A4α type; major menaquinones MK-8, MK-9 and MK-10; predominant fatty acids anteiso-C15 : 0 and anteiso-C17 : 0) that are characteristic of members of the genus Arthrobacter. The isolates shared 97·8 % 16S rRNA gene sequence similarity to each other and were most closely related to Arthrobacter sulfureus (about 98·5 % sequence similarity). DNA–DNA hybridization experiments revealed 50 % relatedness between the isolates, while the levels of DNA–DNA relatedness between strains Lz1yT and KGN15 T and their phylogenetic relative, A. sulfureus, were respectively 54 and 12 %. Based on the above data and distinct phenotypic differences between the isolates and A. sulfureus, two novel species are proposed, Arthrobacter gangotriensis sp. nov. (type strain Lz1yT=DSM 15796T=JCM 12166T) and Arthrobacter kerguelensis sp. nov. (type strain KGN15T=DSM 15797T=JCM 12165T).

In 2001, a Gram-variable, facultatively anaerobic, endospore-forming bacterium isolated from biodeteriorated mural paintings in the Servilia tomb of the Roman necropolis of Carmona was deposited as Paenibacillus strain LMG 19508. Subsequently, the strain was characterized in detail using phenotypic and molecular methods. The 16S rRNA gene sequence confirmed that the strain belongs to the genus Paenibacillus and indicated its relationship to Paenibacillus mendelii CCM 4839T (96.7 % sequence similarity). The predominant menaquinone was MK-7. The cell wall contained meso-diaminopimelic acid of the A1γ type. The DNA G+C content (50 mol%) and the major fatty acid (anteiso-C15 : 0) of strain LMG 19508T were also consistent with its affiliation to the genus Paenibacillus. DNA–DNA hybridization distinguished strain LMG 19508T from other phylogenetically related Paenibacillus species. Therefore, the isolate represents a novel species, for which the name Paenibacillus sepulcri sp. nov. is proposed. The type strain is CCM 7311T (=LMG 19508T).

Three strains, K08-0182T, K08-0178 and K08-0195 were isolated from the paste of ground plant roots collected in Kanagawa Prefecture, Japan. These strains contained meso-diaminopimelic acid and lysine as the diamino acids in cell-wall peptidoglycan, and MK-9(H6) and MK-9(H8) as the predominant menaquinones. The G+C contents of the DNA were 72–73 mol%. Taken together, these characteristics combined with 16S rRNA gene sequence analyses revealed that the isolated strains belong to the genus Actinoallomurus. DNA–DNA hybridization values showed that the three strains belonged to a novel species of the genus Actinoallomurus. Therefore strains K08-0182T, K08-0178 and K08-0195 are proposed as representatives of a novel species, Actinoallomurus radicium sp. nov. The type strain is K08-0182T ( = DSM 45523T  = NBRC 107678T  = JCM 17294T).

An aerobic, Gram-stain-positive actinomycete, designated strain 3SM4-07T, was characterized using a polyphasic taxonomic approach. The strain produced branching mycelium which fragmented into short or elongated rods. The whole-cell hydrolysates contained ll-2,6-diaminopimelic acid as the diagnostic diamino acid, with glucose and ribose as the main sugars. The predominant cellular fatty acids were anteiso-C15  :  0, iso-C15  :  0 and iso-C16  :  0.The predominant menaquinone was MK-9(H4). Phospholipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol and phosphatidylinositol mannoside. Mycolic acids were absent. The DNA G+C content was 72.3 mol%. Strain 3SM4-07T formed a phylogenetic line within the genus Jiangella and its 16S rRNA gene sequence was related most closely to Jiangella alkaliphila D8-87T (99.0 % similarity), Jiangella muralis 15-Je-017T (98.8 %), Jiangella alba YIM 61503T (98.6 %) and Jiangella gansuensis YIM 002T (98.6 %). However, mean DNA–DNA hybridization values revealed that strain 3SM4-07T differed from the closest species previously described in this genus. Data from phenotypic, chemotaxonomic and molecular analyses between strain 3SM4-07T and recognized species of the genus Jiangella indicate that strain 3SM4-07T is a representative of a novel species of the genus Jiangella, for which the name Jiangella mangrovi sp. nov. is proposed. The type strain is 3SM4-07T ( = BCC 60398T = NBRC 109648T).

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).

A polyphasic taxonomic study was performed on 22 thermotolerant, aerobic, endospore-forming bacteria from dairy environments. Seventeen isolates were retrieved from raw milk, one from a filter cloth and four from grass, straw or milking equipment. These latter four isolates (R-6546, R-7499, R-7764 and R-7440) were identified as Bacillus thermoamylovorans based on DNA–DNA hybridizations (values above 70 % with Bacillus thermoamylovorans LMG 18084T) but showed discrepancies in characteristics with the original species description, so an emended description of this species is given. According to 16S rRNA gene sequence analysis and DNA–DNA hybridization experiments, the remaining 18 isolates (R-6488T, R-28193, R-6491, R-6492, R-7336, R-33367, R-6486, R-6770, R-31288, R-28160, R-26358, R-7632, R-26955, R-26950, R-33520, R-6484, R-26954 and R-7165) represented one single species, most closely related to Bacillus thermoamylovorans (93.9 % 16S rRNA gene sequence similarity), for which the name Bacillus thermolactis is proposed. Cells were Gram-stain-positive, facultatively anaerobic, endospore-forming rods that grew optimally at 40–50 °C. The cell wall peptidoglycan type of strain R-6488T, the proposed type strain, was A1γ based on meso-diaminopimelic acid. Major fatty acids of the strains were C16 : 0 (28.0 %), iso-C16 : 0 (12.1 %) and iso-C15 : 0 (12.0 %). MK-7 was the predominant menaquinone, and major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and some unidentified phospholipids. DNA G+C content was 35.0 mol%. Phenotypic properties allowed discrimination from other thermotolerant species of the genus Bacillus and supported the description of the novel species Bacillus thermolactis, with strain R-6488T ( = LMG 25569T  = DSM 23332T) as the proposed type strain.

Two Gram-stain-positive bacterial isolates, strain 2385/12T and strain 2673/12T were isolated from a tapir and a dog's nose, respectively. The two strains were rod to coccoid-shaped, catalase-positive and oxidase-negative. The highest 16S rRNA gene sequence similarity identified Corynebacterium singulare CCUG 37330T (96.3 % similarity) as the nearest relative of strain 2385/12T and suggested the isolate represented a novel species. Corynebacterium humireducens DSM 45392T (98.7 % 16S rRNA gene sequence similarity) was identified as the nearest relative of strain 2673/12T. Results from DNA–DNA hybridization with the type strain of C. humireducens demonstrated that strain 2673/12T also represented a novel species. Strain 2385/12T showed a quinone system consisting predominantly of menaquinones MK-8(H2) and MK-9(H2) whereas strain 2673/12T contained only MK-8(H2) as predominant quinone. The polar lipid profiles of the two strains showed the major compounds phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid. Phosphatidylinositol was identified as another major lipid in 2673/12T whereas it was only found in moderate amounts in strain 2385/12T. Furthermore, moderate to minor amounts of phosphatidylinositol-mannoside, β-gentiobiosyl diacylglycerol and variable counts of several unidentified lipids were detected in the two strains. Both strains contained corynemycolic acids. The polyamine patterns were characterized by the major compound putrescine in strain 2385/12T and spermidine in strain 2673/12T. In the fatty acid profiles, predominantly C18 : 1ω9c and C16 : 0 were detected. The two strains are distinguishable from each other and the nearest related established species of the genus Corynebacterium phylogenetically and phenotypically. In conclusion, two novel species of the genus Corynebacterium are proposed, namely Corynebacterium tapiri sp. nov. (type strain, 2385/12T = CCUG 65456T = LMG 28165T) and Corynebacterium nasicanis sp. nov. (type strain, 2673/12T = CCUG 65455T = LMG 28166T).
