ABSTRACT: A Gram-variable, motile and rod-shaped bacterial strain, ASL-1(T), was isolated from a marine saltern located on the coast of the Yellow Sea, Korea. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain ASL-1(T) clustered with Jeotgalibacillus alimentarius YKJ-13(T) and that this cluster joined the clade comprising the type strains of two Marinibacillus species. Strain ASL-1(T) exhibited 16S rRNA gene sequence similarity values of 97.3 % to J. alimentarius YKJ-13(T) and 96.5 % to the type strains of Marinibacillus marinus and Marinibacillus campisalis. The chemotaxonomic properties of strain ASL-1(T) were similar to those of one or two of the genera Jeotgalibacillus and Marinibacillus. The peptidoglycan type was A1alpha linked directly through L-lysine as the diamino acid. Strain ASL-1(T) contained MK-7 as the predominant menaquinone with the presence of a significant amount of MK-8. The predominant fatty acid was anteiso-C(15 : 0). The DNA G+C content was 42.9 mol%. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain ASL-1(T) could be differentiated from J. alimentarius and the two Marinibacillus species. On the basis of the data presented, strain ASL-1(T) represents a novel species within the genus Jeotgalibacillus, for which the name Jeotgalibacillus salarius sp. nov. is proposed. The type strain is ASL-1(T) (=KCTC 13257(T)=CCUG 56751(T)). It is also proposed that Marinibacillus marinus and Marinibacillus campisalis be reclassified as Jeotgalibacillus marinus comb. nov. (type strain 581(T)=DSM 1297(T)=ATCC 29841(T)=CCUG 28884(T)=CIP 103308(T)=LMG 6930(T)) and Jeotgalibacillus campisalis comb. nov. (type strain SF-57(T)=KCCM 41644(T)=JCM 11810(T)), respectively.

ABSTRACT: A Gram-positive, non-motile, rod- or coccoid-shaped Microbacterium-like bacterium, designated strain DS-66(T), was isolated from soil of Dokdo, Korea, and its exact taxonomic position was investigated by using a polyphasic approach. Strain DS-66(T) grew optimally at 30 degrees C and pH 6.5-7.0 in the presence of 0.5-1.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-66(T) belonged to the genus Microbacterium. Strain DS-66(T) had a peptidoglycan type based on B2beta with partial substitution of glutamic acid by 3-hydroxy glutamic acid (Glu/Hyg-Gly-d-Orn), and galactose, rhamnose and ribose as whole-cell sugars. The acyl type was glycolyl. Strain DS-66(T) contained MK-13, MK-12 and MK-14 as predominant menaquinones and anteiso-C(15 : 0), anteiso-C(17 : 0), iso-C(17 : 0) and iso-C(16 : 0) as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, an unidentified phospholipid and an unidentified glycolipid. The DNA G+C content was 69.9 mol%. Phylogenetic distinctiveness, DNA-DNA relatedness data and differential phenotypic properties demonstrated that strain DS-66(T) is distinguishable from recognized Microbacterium species. On the basis of the data presented, strain DS-66(T) is considered to represent a novel species of the genus Microbacterium, for which the name Microbacterium insulae sp. nov. is proposed. The type strain is DS-66(T) (=KCTC 19247(T)=CCUG 54523(T)).

ABSTRACT: A Gram-positive, yellow-pigmented, non-motile and rod-shaped or coccoid bacterial strain, DS-61T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. The strain grew optimally at pH 6.5-7.5 and 25 degrees C in the presence of 1.0% (w/v) NaCl. Strain DS-61T had peptidoglycan of the type based on L-Lys-L-Thr-D-Asp and contained galactose as the only whole-cell sugar. MK-9(H4) was the predominant menaquinone and anteiso-C15:0 and iso-C15:0 were the major fatty acids. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and an unidentified phospholipid. The DNA G+C content was 72.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-61T is most closely affiliated to the genus Cellulosimicrobium, clustering with Cellulosimicrobium cellulans and Cellulosimicrobium funkei. The levels of 16S rRNA gene sequence similarity between strain DS-61T and the type strains of Cellulosimicrobium cellulans and Cellulosimicrobium funkei were 97.4-97.6%. DNA-DNA relatedness data and differential phenotypic properties demonstrated that strain DS-61T is distinguishable from these two recognized Cellulosimicrobium species. On the basis of phenotypic, phylogenetic and genetic data, strain DS-61T represents a novel species of the genus Cellulosimicrobium, for which the name Cellulosimicrobium terreum sp. nov. is proposed. The type strain is DS-61T (=KCTC 19206T=DSM 18665T). An emended description of the genus is given.

ABSTRACT: A Gram-positive, non-motile, rod- or coccoid-shaped Isoptericola-like bacterium, strain DS-3(T), was isolated from a soil sample from Dokdo, Korea, and its taxonomic position was investigated by a polyphasic approach. The organism grew optimally at 30 degrees C and pH 7.0-8.0. Strain DS-3(T) had the peptidoglycan type based on l-lys-d-Asp, and galactose, glucose, rhamnose and ribose as the whole-cell sugars. It contained MK-9(H(4)) as the predominant menaquinone and anteiso-C(15 : 0) and iso-C(15 : 0) as the major fatty acids. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two unidentified glycolipids. The DNA G+C content was 74.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-3(T) was most closely related to members of the genus Isoptericola. Similarity values between the 16S rRNA gene sequences of strain DS-3(T) and the type strains of Isoptericola species ranged from 98.0 to 98.4 %. DNA-DNA relatedness values (11-23 %) and differential phenotypic properties demonstrated that strain DS-3(T) was distinguishable from recognized Isoptericola species. On the basis of phenotypic properties and phylogenetic and genetic distinctiveness, strain DS-3(T) represents a novel species in the genus Isoptericola, for which the name Isoptericola dokdonensis sp. nov. is proposed. The type strain is DS-3(T) (=KCTC 19128(T)=CIP 108921(T)).

ABSTRACT: Two Gram-positive, non-motile, non-spore-forming and rod-shaped actinomycete strains, KSL-113(T) and KSL-133, were isolated from an alkaline soil in Korea, and their taxonomic positions were investigated by using a polyphasic approach. The strains grew optimally at 30 degrees C and pH 9.0. Phenotypic, phylogenetic and genetic similarities indicated that strains KSL-113(T) and KSL-133 represent the same species. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains KSL-113(T) and KSL-133 fell within the family Microbacteriaceae of the suborder Micrococcineae, the highest 16S rRNA gene sequence similarity values (98.2 %) being obtained with respect to Microcella putealis CV-2(T). The 16S rRNA gene sequence similarities between strains KSL-113(T) and KSL-133 and the other members of the family Microbacteriaceae used in the phylogenetic analysis were less than 96.0 %. Strains KSL-113(T) and KSL-133 could be clearly distinguished from members of the family Microbacteriaceae on the basis of differences in chemotaxonomic properties, including the predominant menaquinone type, the cell-wall peptidoglycan type and the fatty acid profile. Accordingly, on the basis of the combined phenotypic, chemotaxonomic and phylogenetic data, strains KSL-113(T) and KSL-133 constitute a novel genus and species of the family Microbacteriaceae, for which the name Yonghaparkia alkaliphila gen. nov., sp. nov. is proposed. The type strain of Yonghaparkia alkaliphila is KSL-113(T) (=KCTC 19126(T)=CIP 108920(T)).

ABSTRACT: A novel nitrate-reducing bacterium, CPW406T, was isolated from the sediment of a shallow, freshwater lake. The strain was a Gram-negative, non-motile, non-spore-forming rod, which formed yellow-pigmented colonies on nutrient agar and contained a polyamine pattern with sym-homospermidine as the major compound, MK-6 as the predominant menaquinone, 15 : 0 iso and 17 : 0 iso 3-OH as the major fatty acids and phosphatidylethanolamine and several unknown lipids in the polar lipid profile. The 16S rRNA gene sequence of strain CPW406T was found to be most similar to that of the type strain of Chryseobacterium defluvii (DSM 14219T; 97.9 % similarity). However, DNA-DNA relatedness data and its phenotypic properties showed that strain CPW406T could be distinguished from all known Chryseobacterium species and thus represented a novel species, for which the name Chryseobacterium daecheongense sp. nov. is proposed; the type strain is CPW406T (=DSM 15235T=KCTC 12088T).

ABSTRACT: A Gram-positive, motile, round to ellipsoidal, endospore-forming, rod-shaped bacterial strain, SF-57T, was isolated from a marine solar saltern in Korea. This organism grew between 4 and 39 degrees C, with optimum growth at 30 degrees C. Strain SF-57T grew in the presence of 0.5-15.0% NaCl, with optimum growth at 2-3% NaCl. The peptidoglycan type of strain SF-57T was A1alpha linked directly through l-Lys. In strain SF-57TT, menaquinone-7 (MK-7) was the predominant isoprenoid quinone and anteiso-C(15 : 0) was the major fatty acid. The DNA G+C content was 41.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SF-57T formed a coherent cluster with Marinibacillus marinus, with a bootstrap resampling value of 100%. The level of 16S rRNA gene sequence similarity between strain SF-57T and M. marinus DSM 1297T was 98.9%. The mean DNA-DNA relatedness level between strain SF-57T and the type strain of M. marinus was 20.6%. Based on phenotypic properties, phylogenetic analyses and genomic data, strain SF-57T merits placement in the genus Marinibacillus as a representative of a novel species, for which the name Marinibacillus campisalis sp. nov. is proposed. The type strain is SF-57T (=KCCM 41644T=JCM 11810T).
