A taxonomic study was performed on strain D7015T, which was isolated from coastal sediment close to a coal-fired power station in Qingdao, China. Cells of strain D7015T were Gram-positive, non-motile, diphtheroid rods that grew in the presence of 0–8 % (w/v) NaCl and at 4–37 °C, with optimum growth at 1 % (w/v) NaCl and 30–32 °C. The DNA G+C content was 65.0 mol%. The major fatty acids were C18 : 1 ω9c (56.18 %), C16 : 0 (38.02 %), C16 : 1 ω7c (4.45 %), C18 : 0 (1.0 %) and C14 : 0 (0.35 %). On the basis of morphological, physiological and phylogenetic characteristics, strain D7015T was classified in the genus Corynebacterium. It exhibited a 16S rRNA gene sequence similarity of 95.9 % and a DNA–DNA relatedness value of 20.4 % with Corynebacterium halotolerans DSM 44683T. Strain D7015T was sufficiently different from recognized species of the genus Corynebacterium to be considered to represent a novel species. The name Corynebacterium marinum sp. nov. is proposed, with strain D7015T (=CGMCC 1.6998T=NRRL B-24779T) as the type strain.

Micro Organisms

Five strains of lactic acid bacteria were isolated from a compost of distilled shochu residue in Japan. The isolates were separated into two groups on the basis of 16S rRNA gene sequence similarity, and two subclusters were formed that comprised micro-organisms closely related to Lactobacillus buchneri, L. diolivorans, L. hilgardii, L. kefiri, L. parabuchneri and L. parakefiri. DNA–DNA relatedness results revealed that the isolates could be separated into two groups, and these groups correlated well with the subclusters generated using the phylogenetic analysis. Moreover, the levels of DNA–DNA relatedness showed clear separation of the two groups from their phylogenetic relatives. Therefore, the two groups represent two novel species, for which the names Lactobacillus farraginis sp. nov. (type strain NRIC 0676T=JCM 14108T=DSM 18382T) and Lactobacillus parafarraginis sp. nov. (type strain NRIC 0677T=JCM 14109T=DSM 18390T) are proposed.

Beer Spoilage

Three novel strains isolated from brewery environments are described. These strains were Gram-positive, facultatively anaerobic, heterofermentative rods that did not exhibit catalase activity. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that these strains belong to the genus Lactobacillus and are most closely related to Lactobacillus collinoides (approximately 99 % similarity). The novel strains could be differentiated from L. collinoides on the basis of DNA–DNA relatedness, differences in beer-spoilage ability and the inability to utilize d-fructose. These isolates represent a novel species, for which the name Lactobacillus paracollinoides sp. nov. is proposed. The type strain is LA2T (=DSM 15502T=JCM 11969T).

Gene Sequence Analysis

Strain CCM 2783, previously classified as representing Arthrobacter aurescens, was subjected to a polyphasic taxonomic study. 16S rRNA gene sequence analysis and chemotaxonomic characteristics such as peptidoglycan type A3α Lys–Ala2, major menaquinone MK-9(H2) and fatty acid composition confirmed assignment of the strain to the genus Arthrobacter. The results of phylogenetic analysis, DNA–DNA relatedness experiments and physiological and chemotaxonomic characteristics indicate that CCM 2783 differs from its nearest phylogenetic relative Arthrobacter psychrolactophilus and from other recognized Arthrobacter species. Therefore, a novel species, Arthrobacter stackebrandtii sp. nov., is proposed with the type strain CCM 2783T (=DSM 16005T).

A novel haloalkaliphilic archaeon, strain DZ-1T, was isolated from a soda lake in Xinjiang, China. The taxonomy of strain DZ-1T was studied by polyphasic methods. According to 16S rRNA gene sequence similarity, strain DZ-1T was phylogenetically related to Halorubrum tibetense (97·5 %), Halorubrum vacuolatum (95·7 %) and Halorubrum saccharovorum (95·9 %). Strain DZ-1T was able to grow at 20–44 °C and was also physiologically different from the above-mentioned species with respect to assimilation of sugars and utilization of organic acids. The DNA G+C content of strain DZ-1T was 62·1 mol% (T m). The DNA–DNA relatedness of strain DZ-1T to H. tibetense and H. vacuolatum was 22 and 13 %, respectively. It was concluded that strain DZ-1T represents a novel species of the genus Halorubrum, for which the name Halorubrum alkaliphilum (type strain, DZ-1T=AS 1.3528T=JCM 12358T) is proposed.

Gram-positive, rod-shaped, motile lactic acid bacteria (strains NRIC 0603, NRIC 0604T, NRIC 0605 and NRIC 0606) were isolated from shochu mashes using an enrichment culture approach. These strains clustered in the Lactobacillus casei–Pediococcus group and were closely related to Lactobacillus nagelii and Lactobacillus mali on the basis of 16S rRNA gene sequence similarity. Levels of DNA–DNA relatedness revealed genotypic separation of the four isolates from the above two species. The isolates are therefore considered to represent a novel species, for which the name Lactobacillus satsumensis is proposed. The type strain is NRIC 0604T (=JCM 12392T=DSM 16230T).

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).

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).

A Gram-reaction-positive, rod-shaped, spore-forming bacterium, designated Gsoil 1105T, was isolated from soil of a ginseng field in Pocheon Province in South Korea and characterized in order to determine its taxonomic position. Comparative analysis of the 16S rRNA gene sequence showed that the isolate belongs to the order Bacillales, showing the highest level of sequence similarity with respect to Tumebacillus permanentifrigoris Eur1 9.5T (94.6 %). The phylogenetic distances from other described species with validly published names within the order Bacillales were greater than 9.0 %. Strain Gsoil 1105T had a genomic DNA G+C content of 55.6 mol% and menaquinone 7 (MK-7) as the major respiratory quinone. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1105T represents a novel species of the genus Tumebacillus, for which the name Tumebacillus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 1105T ( = KCTC 13942T  = DSM 18389T).
