Two actinomycete strains, IFM 0354T and IFM 0576, isolated from Japanese patients, were found to have morphological, biochemical and chemotaxonomic properties consistent with their classification in the genus Nocardia. The strains resembled Nocardia otitidiscaviarum and Nocardia uniformis in their phenotypic properties. Comparative 16S rRNA gene sequence analysis showed that the strains are closely related to Nocardia seriolae. DNA–DNA relatedness values and phenotypic differences from N. seriolae indicated that the strains belong to a novel species of Nocardia, for which the name Nocardia concava sp. nov. is proposed. The type strain is IFM 0354T (=NBRC 100430T=JCM 12351T=DSM 44804T).

Actinomycete Strain

A novel actinomycete, strain N3-7T, was isolated from a natural cave in Jeju, Republic of Korea, using a dilution method and was subjected to characterization using polyphasic taxonomy. A 16S rRNA gene sequence analysis revealed that the organism belonged to the phylogenetic cluster of the genus Actinocorallia and was most closely related to Actinocorallia glomerata and Actinocorallia longicatena (97.6 and 97.5 % similarity, respectively). The main chemotaxonomic properties of strain N3-7T, such as the principal amino acid of the peptidoglycan, the predominant menaquinone and the polar lipid profile, supported classification in the genus Actinocorallia. The organism was readily differentiated from Actinocorallia species with validly published names on the basis of a broad range of phenotypic properties. Thus the isolate represents a novel species of the genus Actinocorallia, for which the name Actinocorallia cavernae sp. nov. is proposed. The type strain is strain N3-7T (=JCM 13278T=NRRL B-24429T).

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.

Two novel Gram-negative, oxidase- and catalase-positive, rod-shaped bacterial strains, designated YCSA28T and YCSA39, were isolated from sediment of Daqiao saltern, Jimo, Qingdao, on the east coast of China. The two strains grew optimally at 28–30 °C, at pH 7.5 and in the presence of 7–8 % (w/v) NaCl. They were assigned to the genus Halomonas, class Gammaproteobacteria, based on 16S rRNA gene sequence analysis. The major cellular fatty acids of the two strains were C18 : 1ω7c (42.9 %), C16 : 0 (23.1 %) and C16 : 1ω7c/ω6c (18.0 %), and Q-9 was the major ubiquinone. The G+C content of the DNA of strains YCSA28T and YCSA39 was 63.7 and 63.9 mol%, respectively. The predominant respiratory lipoquinone, cellular fatty acid profiles and DNA G+C content of strains YCSA28T and YCSA39 were consistent with those of recognized species of the genus Halomonas. Levels of DNA–DNA relatedness between strains YCSA28T and YCSA39, between YCSA28T and Halomonas ventosae Al12T, and between YCSA39 and H. ventosae Al12T were 95, 45 and 50 %, respectively. Together, these data indicated that strains YCSA28T and YCSA39 represent a single novel species of the genus Halomonas, for which the name Halomonas daqiaonensis sp. nov. is proposed. The type strain is YCSA28T ( = CGMCC 1.9150T  = NCCB 100305T  = MCCC 1B00920T).

Two Gram-negative, vibrioid, phototrophic, purple non-sulfur strains, JA131T and JA135T, were isolated from marine habitats. Strain JA131T is non-motile but strain JA135T is motile by means of a pair of monopolar flagella. Both strains have an obligate requirement for NaCl for growth. The intracellular photosynthetic membranes of the two novel strains are of the vesicular type. Bacteriochlorophyll a and probably rhodovibrine are present as photosynthetic pigments. Niacin, thiamine and p-aminobenzoic acid are required as growth factors for both novel strains. Based on 16S rRNA gene sequence analysis, morphological and physiological characteristics, strains JA131T and JA135T are significantly different from each other and from other species of the genus Roseospira and thus represent two novel species for which the names Roseospira visakhapatnamensis sp. nov. and Roseospira goensis sp. nov. are proposed, respectively. The type strain of Roseospira visakhapatnamensis sp. nov. is JA131T (=ATCC BAA-1365T=JCM 14190T) and the type strain of Roseospira goensis sp. nov. is JA135T (=ATCC BAA-1364T=JCM 14191T).
