<Emphasis Type="Italic">Terrabacter ginsengisoli</Emphasis> sp. nov., isolated from ginseng cultivating soil

A Gram-positive, strictly aerobic, nonmotile, yellowish, coccus-rod-shaped bacterium (designated Gsoil 653^T) isolated from ginseng cultivating soil was characterized using a polyphasic approach to clarify its taxonomic position. The strain Gsoil 653^T exhibited optimal growth at pH 7.0 on R2A agar medium at 30°C. Phylogenetic analysis based on 16S rRNA gene sequence similarities, indicated that Gsoil 653^T belongs to the genus Terrabacter of the family Humibacillus, and was closely related to Terrabacter tumescens DSM 20308^T (98.9%), Terrabacter carboxydivorans PY2^T (98.9%), Terrabacter terrigena ON10^T (98.8%), Terrabacter terrae PPLB^T (98.6%), and Terrabacter lapilli LR-26^T (98.6%). The DNA G + C content was 70.5 mol%. The major quinone was MK-8(H₄). The primary polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidyl-ethanolamine. The predominant fatty acids were iso-C_15:0, iso-C_16:0, iso-C_14:0, and anteiso-C_15:0, as in the case of genus Terrabacter, thereby supporting the categorization of strain Gsoil 653^T. However, the DNA-DNA relatedness between Gsoil 653^T and closely related strains of Terrabacter species was low at less than 31%. Moreover, strain Gsoil 653^T could be both genotypically and phenotypically distinguished from the recognized species of the genus Terrabacter. This isolate, therefore, represents a novel species, for which the name Terrabacter ginsengisoli sp. nov. is proposed with the type strain Gsoil 653^T (= KACC 19444^T = LMG 30325^T).

The predominant fatty acids were iso-C_15:0, iso-C_16:0, and summed feature 9 (iso-C_17:1ω9c), with Q-8 identified as the major ubiquinone. The polar lipid content included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unknown aminophospholipid, and an unidentified phospholipid. DNA-DNA hybridization results indicated that the strain IPC6^T was distinct from Lysobacter niastensis KACC 11588^T (37.9 ± 0.14%), Lysobacter panacisoli KACC 17502^T (56.4 ± 0.13%), Lysobacter soli KCTC 22011^T (8.1 ± 0.04%), Lysobacter gummosus KCTC 12132^T (9.6 ± 0.03%), and Lysobacter cavernae KCTC 42875^T (37.5 ± 0.14%), respectively. The DNA G + C content of the novel strain was 71.1 mol%. Based on the collective phenotypic, genotypic and chemotaxonomic data, the IPC6^T strain is considered to represent a novel species in the genus Lysobacter, for which the name Lysobacter pedocola sp. nov. (= KCTC 42811^T = JCM 31020^T) is proposed.

Gram-positive, aerobic, non-motile, pale-yellow, and rodshaped bacterium, designated as Gsoil 188^T, was isolated from the soil of a ginseng field in Pocheon, South Korea. A phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that the strain formed a distinct lineage within the genus Brevibacterium and was most closely related to B. epidermidis NBRC 14811^T (98.4%), B. sediminis FXJ8.269^T (98.2%), B. avium NCFB 3055^T (98.1%), and B. oceani BBH7^T (98.1%), while it shared less than 98.1% identity with the other species of this genus. The DNA G + C content was 68.1 mol%. The predominant quinone was MK-8(H₂). The major fatty acids were anteiso-C_15:0 and anteiso-C_17:0. The cell wall peptidoglycan of strain Gsoil 188^T contained meso-diaminopimelic acid. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, and an unidentified aminolipid. The physiological and biochemical characteristics, low DNA-DNA relatedness values, and taxonomic analysis allowed the differentiation of strain Gsoil 188^T from the other recognized species of the genus Brevibacterium. Therefore, strain Gsoil 188^T represents a novel species of the genus Brevibacterium, for which the name Brevibacterium anseongense sp. nov. is proposed, with the type strain Gsoil 188^T (= KACC 19439^T = LMG 30331^T).

The polar lipids consisted of phosphatidylethanolamine, aminophospholipid, three unidentified aminolipids and five unidentified lipids. The genomic DNA G+C content was determined to be 53.2 ± 1.6 mol%. On the basis of phylogenetic, chemotaxonomic and phenotypic data, strain LAM9153^T is concluded to represent a novel species of the genus Chitinophaga, for which the name Chitinophaga salinisoli sp. nov. is proposed. The type strain is LAM9153^T (= ACCC 19960^T = JCM 30847^T).     

<Emphasis Type="Italic">Algoriphagus formosus</Emphasis> sp. nov., isolated from coastal sediment

A Gram-stain negative, facultative anaerobic, non-motile, strongly orange-pigmented and rod-shaped bacterium, designated XAY3209^T, was isolated from a marine sediment sample collected from the coast of Weihai, China. Strain XAY3209^T was found to grow optimally at 30 °C, at pH 7.0 and in the presence of 2.0% (w/v) NaCl. Its genomic DNA G+C content was 41.9 mol%. On the basis of 16S rRNA gene sequence similarity, the novel isolate belongs to the family Cyclobacteriaceae and is related to the genus Algoriphagus. It shares 98.1% 16S rRNA sequence identity with Algoriphagus marincola, its close phylogenetic relative, but did not show similarities more than 97% with other members of the genus Algoriphagus with validly published names. It contained menaquinone-7 (MK-7) as the sole respiratory quinone, iso-C_15:0, iso-C_17:1 ω9c and Summed feature 3 (C_16:1 ω7c and/or iso-C_15:0 2-OH) as the major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and five unidentified lipids. Results of physiological experiments, biochemical tests and genome average nucleotide identity value (with A. marincola MCCC 1F01203^T) indicate that strain XAY3209^T is genetically and phenotypically distinct from the species of the genus Algoriphagus with validly published names. Strain XAY3209^T therefore represents a novel species, for which the name Algoriphagus formosus sp. nov. is proposed. The type strain is XAY3209^T (= KCTC 52842^T = MCCC 1H00189^T).     

<Emphasis Type="Italic">Flavobacterium knui</Emphasis> sp. nov., a novel member of the family <Emphasis Type="Italic">Flavobacteriaceae</Emphasis>

A Gram-stain negative, non-motile, rod-shaped bacterial strain, designated 2-56^T, was isolated from water and characterized taxonomically using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain 2-56^T belongs to the family Flavobacteriaceae in the phylum Bacteroidetes and is closely related to Flavobacterium paronense KNUS1^T (98.4%) and Flavobacterium collinsense 4-T-2^T (96.7%). The G?+?C content of the genomic DNA of strain 2-56^T was 33.4 mol%. The isolate contained MK-6 as the predominant respiratory quinone, and iso-C_15:1 G (15.9%), iso-C_15:0 (15.8%), iso-C_17:0 3-OH (10.7%), and iso-C_15:0 3-OH (9.6%) were the major fatty acids. The major polar lipids were phosphatidylethanolamine and an unidentified lipid. The phenotypic and chemotaxonomic data support the affiliation of strain 2-56^T with the genus Flavobacterium. However, the DNA–DNA relatedness between the isolate and F. paronense and F. collinsense were 35.7 and 21.5%, respectively, clearly showing that strain 2-56^T is not related to them at the species level. Strain 2-56^T could be clearly differentiated from its close neighbours on the basis of its phenotypic, genotypic and chemotaxonomic features. Therefore, strain 2-56^T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium knui sp. nov. is proposed. The type strain is 2-56^T (=?KCTC 62061^T?=?JCM 32247^T).
