A non-lipophilic coryneform bacterium, strain 3105T, was isolated from various tissues of a ferret with lethal sepsis. The strain was characterized by phenotypic and chemotaxonomic methods, which suggested an assignment of the isolate to the genus Corynebacterium. Strain 3105T exhibited the following peculiar features that made it possible to differentiate it phenotypically from all other corynebacteria: its distinctive ‘humid cellar’-like odour, strong adherence to agar and a greenish-beige pigment. Strain 3105T exhibited more than 2.8 % 16S rRNA gene sequence divergence from its closest phylogenetic neighbour, Corynebacterium pseudotuberculosis NCTC 3450T (97.12 % sequence similarity). Analysis of the highly variable region within the rpoB gene sequence showed that strain 3105T exhibited more than 14 % divergence from its closest phylogenetic relative, again C. pseudotuberculosis. Based on the data presented, it is proposed that the ferret isolate should be classified within a novel species, Corynebacterium mustelae sp. nov. (type strain 3105T =CCUG 57279T =DSM 45274T).

A Gram-positive, yellowish bacterium strain AK-1Twas isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genusAgromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1Twas closely related toAgromyces aurantiacus(98.6%) followed byAgromyces soli(98.3%),Agromyces tropicus(97.6%),Agromyces ulmi(97.3%),Agromyces flavus(97.2%), andAgromyces italicus(97.0%), whereas the sequence similarity values with respect to the otherAgromycesspecies with validly published names were between 95.3 and 96.7 %. However, the DNA-DNA hybridization values obtained between strain AK-1Tand other related strains were well below the threshold that is required for the proposal of a novel species. The DNAG+Ccontent of the strain is 71.8 mol%. The above data in combination with the phenotypic distinctiveness of AK-1Tclearly indicate that the strain represents a novel species, for which the nameAgromyces arachidissp. nov. is proposed. The type strain is AK-1T(=MTCC 10524T= JCM 19251T).

A facultatively anaerobic, Gram-stain-negative, non-motile and rod-shaped bacterium, strain N-10T, was isolated from the gut of the termite Reticulitermes speratus. Strain N-10T was closely related to Dysgonomonas gadei JCM 16698T according to 16S rRNA gene sequence similarity analysis (98 %) and DNA–DNA relatedness value (≤61.3 %). The optimum growth temperature of strain N-10T was 30 °C, which was distinct from that (37 °C) of known species of the genus Dysgonomonas . Growth of strain N-10T was inhibited on medium containing 5 or 20 % bile, unlike other species of the genus Dysgonomonas . In addition, acid production in the API 20A system and enzymic reactions in the Rapid ID 32A system of strain N-10T differed from those of other species of the genus Dysgonomonas . Based on these characteristics, strain N-10T represents a novel species of the genus Dysgonomonas , for which the name Dysgonomonas termitidis sp. nov. is proposed. The type strain is N-10T ( = JCM 30204T = CCUG 66188T).

The novel actinomycete strain PWB-003T, which produced fluostatins B and C antibiotics, was isolated from nearshore sediment collected from Panwa Cape, Phuket Province, Thailand. Data from the present polyphasic study indicated that strain PWB-003T represented a member of the genus Micromonospora. It produced single spores on substrate mycelia and contained meso-diaminopimelic acid in the cell-wall peptidoglycan. Whole-cell hydrolysate contained ribose, xylose, arabinose, mannose and glucose. The predominant menaquinone was MK-10 (H4). Cellular fatty acids comprised C18 : 1ω9c, iso-C16 : 0, anteiso-C17 : 0, iso-C15 : 0 and iso-C17 : 0. On the basis of 16S rRNA gene sequence similarity analysis, the novel strain was closely related to Micromonospora eburnea LK2-10T (99.38 %), Micromonospora chaiyaphumensis MC5-1T (99.16 %), Micromonospora yangpuensis FXJ6.011T (98.97 %), Micromonospora echinaurantiaca DSM 43904T (98.97 %), Micromonospora pallida DSM 43817T (98.97 %), Micromonospora sagamiensis DSM 43912T and Micromonospora auratinigra JCM 12357T (both 98.97 %). The G+C content of the DNA was 74.5 mol%. DNA–DNA relatedness values among strain PWB-003T and related type strains ranged from 11.3 ± 1.3 to 38.8 ± 1.1 %. On the basis of these observations, strain PWB-003T could be distinguished from its closely related type strains and is considered to represent a novel species of the genus Micromonospora, for which the name Micromonospora fluostatini sp. nov. (type strain PWB-003T = JCM 30529T = PCU 341T = TISTR 2345T) is proposed.

A novel Gram-positive bacterium, strain A35T, was isolated from coastal soil at Chiba, Japan, and was identified as a member of the genus Paenibacillus on the basis of phenotypic and phylogenetic analyses. The bacterium was found to be a facultatively anaerobic and endospore-forming rod. The predominant menaquinone was MK-7, the major cellular fatty acid was anteiso-C15 : 0 and the DNA G+C content was 48.1 mol%. The levels of 16S rRNA gene sequence similarity between strain A35T and Paenibacillus species with validly published names were less than 94 %. Strain A35T was clearly distinguishable from reference species for the genus Paenibacillus. Therefore, on the basis of these data, a novel species of the genus Paenibacillus, Paenibacillus terrigena sp. nov., is proposed. The type strain is A35T (=IAM 15291T=CCTCC AB206026T).

A Gram-negative, non-sporulating, non-flagellated rod, designated BR-9T, was isolated from soil collected on the Korean peninsula. Strain BR-9T grew optimally at pH 6.0–7.0, at 30 °C and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BR-9T belonged to the genus Pedobacter and clustered with Pedobacter insulae DS-139T and Pedobacter koreensis WPCB189T. Strain BR-9T exhibited 98.2 and 97.5 % 16S rRNA gene sequence similarity with P. insulae DS-139T and P. koreensis WPCB189T, respectively, and <96.7 % sequence similarity with the type strains of other species in the genus Pedobacter. Strain BR-9T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C content of strain BR-9T was 38.5 mol%. DNA–DNA relatedness between strain BR-9T and P. insulae DS-139T and P. koreensis KCTC 12536T was 3.4–4.2 %, which indicated that the isolate was genetically distinct from these type strains. Strain BR-9T was also distinguishable by differences in phenotypic properties. On the basis of the data presented, strain BR-9T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter boryungensis sp. nov. is proposed. The type strain is BR-9T ( = KCTC 23344T  = CCUG 60024T).

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).
