<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).

DNA–DNA relatedness between TX0651^T and F. ginsenosidimutans KCTC 22818^T and F. ginsengiterrae KCTC 12656^T were determined to be less than 40%. The low levels of DNA–DNA relatedness identifies the strain TX0651^T as a novel species in the genus Flavisolibacter. The major cellular fatty acids were identified as iso-C_15:0, summed feature 3 (C_16:1 ω7c and/or C_16:1 ω6c), iso-C_15:1 G and iso-C_17:0 3-OH.

The polar lipids were found to be comprised of phosphatidylethanolamine, unidentified amino-glycophospholipids, an unidentified aminophospholipid, an unidentified amino lipid and unidentified lipids. The DNA G+C content of the strain was determined to be 31.2 mol%. On the basis of the phenotypic, genotypic and chemotaxonomic characteristics, strain TX0651^T should be classified in a novel species in the genus Flavisolibacter, for which the name Flavisolibacter carri sp. nov. (=?KACC 19014^T?=?KCTC 52836^T?=?NBRC 111784^T) is proposed.

The menaquinones were identified as MK-9(H₈), MK-9(H₆) and MK-9(H₄). The phospholipid profile was found to consist of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, an unidentified phospholipid and an unidentified lipid. The major fatty acids were identified as anteiso-C_15:0, iso-C_16:0, C_16:0 and C_15:0. However, multilocus sequence analysis based on five house-keeping genes (atpD, gyrB, rpoB, recA and trpB), low DNA-DNA hybridization results and some phenotypic, physiological and biochemical properties could differentiate the strain from its close relatives in the genus Streptomyces. Therefore, strain NEAU-QTH3-11^T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces lutosisoli sp. nov. is proposed, with NEAU-QTH3-11^T (=DSM 42165^T=CGMCC 4.7198^T) as the type strain.

The DNA–DNA relatedness between an-chi-1^T and the type strains of C. iranensis and C. flavigena DSM20109^T are 35.4% and 23.7%, respectively. The major cellular fatty acids are anteiso-C_15:0 and C_14:0. The polar lipid profile consists of diphosphatidylglycerol, phosphatidylinositol mannosides, phosphatidylinositol dimannosides and one unidentified phospholipid. The cell-wall sugar is ribose. The peptidoglycan contains glutamic acid, aspartic acid and alanine. The DNA G+C content is 67.3 mol%. Based on its distinctive phenotypic, phylogenetic, and chemotaxonomic characteristics, an-chi-1^T represents a novel species of the genus Cellulomonas, for which the name Cellulomonas macrotermitis sp. nov. is proposed. The type strain is an-chi-1^T (= JCM 31923^T = CICC 24195^T).     

<Emphasis Type="Italic">Paenibacillus oryzisoli</Emphasis> sp. nov., isolated from the rhizosphere of rice

A novel bacterium, strain 1ZS3-15^T, was isolated from rhizosphere of rice. Its taxonomic position was investigated using a polyphasic approach. The novel strain was observed to be Gram-stain positive, spore-forming, aerobic, motile and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 1ZS3-15^T was recovered within the genus Paenibacillus. It is closely related to Paenibacillus pectinilyticus KCTC 13222^T (97.9 % similarity), Paenibacillus frigoriresistens CCTCC AB 2011150^T (96.8 %), Paenibacillus alginolyticus JCM 9068^T (96.4 %) and Paenibacillus chondroitinus DSM 5051^T (95.5 %). The fatty acid profile of strain 1ZS3-15^T, which showed a predominance of anteiso-C_15:0 and iso-C_16:0, supported the allocation of the strain into the genus Paenibacillus. The predominant menaquinone was found to be MK-7. The polar lipids profile of strain 1ZS3-15^T was found to consist of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unidentified lipid and two unidentified aminophospholipids. The cell wall peptidoglycan contains meso-diaminopimelic acid. Based on draft genome sequences, the DNA–DNA relatedness between strain 1ZS3-15^T and the closely related species P. pectinilyticus KCTC 13222^T are 24.2 ± 1.0 %, and the Average Nucleotide Identity values between the strains are 78.9 ± 0.1 %, which demonstrated that this isolate represents a new species in the genus Paenibacillus. The DNA G+C content was determined to be 45.3 mol%, which is within the range reported for Paenibacillus species. Characterisation by genotypic, chemotaxonomic and phenotypic analysis indicated that strain 1ZS3-15^T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus oryzisoli sp. nov. is proposed. The type strain is 1ZS3-15^T (= ACCC 19783^T = JCM 30487^T).
