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.

Type Strains

Three Gram-positive-staining strains isolated from fermented stinky tofu brine were rod-shaped, non-motile, asporogenous, facultatively anaerobic, heterofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, rpoA and pheS gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence similarity, the type strains of Lactobacillus collinoides (98.6 %), Lactobacillus paracollinoides (98.6 %) and Lactobacillus similis (99.6 %) were the closest neighbours. However, DNA–DNA reassociation values with these strains were less than 10 %. The phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus odoratitofui sp. nov. is proposed. The type strain is YIT 11304T (=JCM 15043T =BCRC 17810T =DSM 19909T).

A novel actinomycete, strain SST-8T, was isolated from sand sediment of Samyang Beach in Jeju, Korea, and subjected to a polyphasic taxonomic study. The organism, which produced opaque, circular, yellow colonies, with a coryneform morphology, showed the following chemotaxonomic characteristics: meso-diaminopimelic acid as the diamino acid in the peptidoglycan, MK-8(H2) as the major menaquinone, phosphatidylglycerol as the only polar lipid, anteiso-C15 : 0 and anteiso-C17 : 0 as major fatty acids and a DNA G+C content of 70.7 mol%. The combination of morphological and chemotaxonomic features supported its classification in the genus Brevibacterium. Phylogenetic analyses, based on 16S rRNA gene sequence studies, showed that strain SST-8T formed an intermediate branch between the Brevibacterium luteolum/Brevibacterium otitidis and Brevibacterium mcbrellneri/Brevibacterium paucivorans clusters. Sequence similarity calculations based on a neighbour-joining analysis revealed that the closest relatives of strain SST-8T were the type strains of B. paucivorans (96.6 %), B. luteolum (96.5 %), B. mcbrellneri (96.3 %), Brevibacterium avium (96.0 %) and B. otitidis (95.9 %). Based on a broad set of phenotypic and genetic data, it was evident that the strain represents a novel species of the genus Brevibacterium. The name Brevibacterium samyangense sp. nov. is proposed, with SST-8T (=NRRL B-41420T=KCCM 42316T) as the type strain.

An actinomycete, strain 4776T, was isolated from soil collected from Emei Mountain in Sichuan Province, China. The taxonomic status of this strain was established using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of streptomycetes. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that the novel isolate belongs to the genus Streptomyces and consistently falls into a clade together with Streptomyces prasinopilosus DSM 40098T, Streptomyces prasinus JCM 4603T, Streptomyces bambergiensis DSM 40590T, Streptomyces hirsutus DSM 40095T and Streptomyces cyanoalbus DSM 40198T. However, DNA–DNA relatedness and phenotypic data distinguished strain 4776T from these phylogenetically related type strains. It is therefore concluded that strain 4776T (=CGMCC 4.3504T=DSM 41884T) represents a novel species of the genus Streptomyces, for which the name Streptomyces emeienseis sp. nov. is proposed.

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).

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).
