The Mean

Two novel Pediococcus strains, Z-9T and Z-17, were isolated from a distilled-spirit-fermenting cellar in Hebei Province, China. The cells were Gram-positive, non-spore-forming, non-motile cocci and occurred in pairs or tetrads. The strains were facultatively anaerobic and produced only lactic acid [d(−) and l(+) isomers in the ratio 50 : 50] from glucose fermentation. Catalase activity was not present. Both strains were able to grow in 6.5 % ethanol and at pH 3.5, but not in 4 % NaCl. The mean genomic G+C content of the two strains was 39.5±0.5 mol% (39 mol% for the type strain, Z-9T). The levels of 16S rRNA gene sequence similarity between the two novel strains and related species of the genus Pediococcus ranged from 98.3 to 98.7 %. The levels of DNA–DNA relatedness between strain Z-9T and the phylogenetically closely related pediococci Pediococcus damnosus LMG 11484T, Pediococcus inopinatus LMG 11409T, Pediococcus parvulus LMG 11486T and Pediococcus cellicola LMG 22956T were 14.6, 33, 28.7 and 16.8 %, respectively. On the basis of phenotypic, genotypic and phylogenetic analyses, a novel species, Pediococcus ethanolidurans sp. nov., is proposed, with strain Z-9T (=AS 1.3889T=LMG 23354T) as the type strain.

The Mean

Two novel Lactobacillus strains, C-5-1T and HB5, were isolated from the walls of a distilled spirit fermenting cellar in Hebei province, China. The strains were Gram-positive, non-spore-forming, non-motile curved rods and were facultatively anaerobic. They produced 5 % (−)-d/95 % (+)-l lactic acid exclusively from glucose fermentation, but were catalase-negative. Both strains fermented N-acetylglucosamine, arbutin, salicin, cellobiose, maltose, trehalose and β-gentiobiose. The mean DNA G+C content of the two strains was 46·9±0·8 mol% (46·4 mol% for the type strain, C-5-1T). Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain C-5-1T was clustered in the Lactobacillus casei/Pediococcus phylogenetic group and was closely related to Pediococcus dextrinicus JCM 5887T (97·9 % similarity), followed by Lactobacillus algidus JCM 10491T (93·9 % similarity). The DNA–DNA relatedness between the type strain C-5-1T and P. dextrinicus JCM 5887T and L. algidus JCM 10491T was only 5·4 and 4·3 %, respectively. Therefore, based on phenotypic, genotypic and phylogenetic analyses, a novel Lactobacillus species, Lactobacillus concavus sp. nov., is proposed. The type strain is C-5-1T (=AS 1.5017T=LMG 22739T).

Strain HHS 11T was isolated from a water sample collected from the snout of Hamta glacier located in the Himalayan mountain ranges of India. Phenotypic, chemotaxonomic and phylogenetic analyses established the affiliation of the isolate to the genus Dyadobacter. HHS 11T possessed 96 and 95 % 16S rRNA gene sequence similarity with respect to Dyadobacter crusticola and Dyadobacter fermentans, respectively. Furthermore, strain HHS 11T differs from D. crusticola and D. fermentans in a number of phenotypic characteristics. These data suggest that strain HHS 11T represents a novel species of the genus Dyadobacter, for which the name Dyadobacter hamtensis sp. nov. is proposed. The type strain is HHS 11T (=JCM 12919T=MTCC 7023T).

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-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.

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.

Six new Vibrio-like isolates originating from different species of bleached and healthy corals around Magnetic Island (Australia) were investigated using a polyphasic approach. Phylogenetic analyses based on 16S rRNA, recA and rpoA gene sequences split the isolates in two new groups. Strains LMG 22223T, LMG 22224, LMG 22225, LMG 22226 and LMG 22227 were phylogenetic neighbours of Photobacterium leiognathi LMG 4228T (95·6 % 16S rRNA gene sequence similarity), whereas strain LMG 22228T was related to Enterovibrio norvegicus LMG 19839T (95·5 % 16S rRNA gene sequence similarity). The two new groups can be distinguished from closely related species on the basis of several phenotypic features, including fermentation of d-mannitol, melibiose and sucrose, and utilization of different compounds as carbon sources, arginine dihydrolase activity, nitrate reduction, resistance to the vibriostatic agent O/129 and the presence of fatty acids 15 : 0 iso and 17 : 0 iso. The names Photobacterium rosenbergii sp. nov. (type strain LMG 22223T=CBMAI 622T=CC1T) and Enterovibrio coralii sp. nov. (type strain LMG 22228T=CBMAI 623T=CC17T) are proposed to accommodate these new isolates. The G+C contents of the DNA of the two type strains are respectively 47·6 and 48·2 mol%.

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).

A Gram-negative, rod-shaped, motile, non-spore-forming bacterium, designated strain A62-14BT, was isolated from a constant-temperature, spring-fed, freshwater lake. On the basis of the complete 16S rRNA gene sequence, strain A62-14BT was shown to belong to the class Gammaproteobacteria, being most closely related to Rheinheimera sp. HTB082 (96.2 % sequence similarity), Rheinheimera baltica (95.01 %), Rheinheimera pacifica (96.35 %), Rheinheimera perlucida and Alishewanella fetalis (95.9 %). The major fatty acids (C16 : 1 ω7c, 38.56 %; C16 : 0, 19.04 %; C12 : 0 3-OH, 12.83 %; C18 : 1 ω7c, 7.70 %) and the motility of strain A62-14BT support its affiliation to the genus Rheinheimera. The salt intolerance of strain A62-14BT, together with the results of other physiological and biochemical tests, allowed the differentiation of this strain from the three species of the genus Rheinheimera with validly published names. Therefore strain A62-14BT represents a novel species of the genus Rheinheimera, for which the name Rheinheimera texasensis sp. nov. is proposed. The type strain is A62-14BT (=ATCC BAA-1235T=DSM 17496T). The description of the genus Rheinheimera is emended to reflect the halointolerance and freshwater origin of strain A62-14BT.
