Bacterium Strain

A Gram-stain-positive, non-motile, coccus-shaped bacterium, strain THG-a14T, was isolated from soil of Gyeyang mountain in Incheon, Republic of Korea. The isolate grew optimally at 28 °C, at pH 6.5–7.5 and with 0–3 % (w/v) NaCl. Based on 16S rRNA gene sequence comparisons, strain THG-a14T was closely related to Phycicoccus aerophilus 5516T-20T (97.7 %), P. ginsenosidimutans BXN5-13T (97.6 %), ‘P. ochangensis’ L1b-b9 (97.4 %) and P. bigeumensis MSL-03 (97.2 %). The DNA G+C content of strain THG-a14T was 71.6 mol%. In DNA–DNA hybridization, the DNA–DNA relatedness between strain THG-a14T and its closest phylogenetically neighbours was below 50.0 %. Strain THG-a14T was characterized chemotaxonomically as having meso-diaminopimelic acid in the cell-wall peptidoglycan. Strain THG-a14T contained glucose and ribose as whole-cell-wall sugars and menaquinone MK-8(H4) as the major isoprenoid quinone. Polar lipids in strain THG-a14T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphoaminoglycolipids, unidentified phospholipids and unidentified lipids. The major fatty acids were iso-C16: 0, iso-C15: 0 and C17: 1ω8c. On the basis of our polyphasic taxonomy study, strain THG-a14T represents a novel species within the genus Phycicoccus, for which the name Phycicoccus soli sp. nov. is proposed. The type strain is THG-a14T ( = KACC 17892T = JCM 19837T).

Fermented Shrimp Paste

Abstract The moderately halophilic, Gram-stain-positive, spore-forming rods, designated SKP4-8T and SKP8-2T isolated from a traditional fermented shrimp paste (Ka-pi), were taxonomic studied based on polyphasic approach. Strain SKP4-8T grew at pH 6.0-9.0 (optimum 7.0), at 25-45°C (optimum 37°C) and in 1-16 % (w/v) NaCl (optimum 5-10). Strain SKP8-2T grew at pH 6.0-9.0 (optimum 8.0), at 25-45°C (optimum 37°C) and in 0-20 % (w/v) NaCl (optimum 3-10 %). The strains contained meso-diaminopimelic acid in cell-wall peptidoglycan and the major menaquinone was MK-7. Strain SKP4-8T contained iso-C15:0, antesio-C15:0 and iso-C17:0; and strain SKP8-2T contained antesio-C15:0, iso-C15:0, iso-C16:0 and antesio-C17:0 as major cellular fatty acids.Phosphatidylglycerol, diphosphatidylglycerol, unknown phospholipids and an unknown glycolipid were detected as major polar lipids. On the basis of 16S rRNA gene sequence analysis, strains SKP4-8T and SKP8-2T belonged to the genus Allobacillus and was closely related to Allobacillus halotolerans LMG 24826T with 98.8 % and 99.3 % similarity, respectively. The comparative genome analysis based on average nucleotide identity (ANI) and digital DNA-DNA hybridization revealed that both strains showed the values below 95 and 70 %, from each other and the Allobacillus halotolerans LMG 24826T, respectively. Based on data from this polyphasic study, strains SKP4-8T and SKP8-2T represent the novel species of the genus Allobacillus and the name Allobacillus salarius sp. nov. was proposed for SKP4-8T (=KCTC 33905T =LMG 30016T =TISTR 2499T); and Allobacillus saliphilus sp. nov. for SKP8-2T (=KCTC 33906T =LMG 29682T =TISTR 2558T).

A Gram-positive, yellowish bacterium strain AK-1Twas isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genusAgromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1Twas closely related toAgromyces aurantiacus(98.6%) followed byAgromyces soli(98.3%),Agromyces tropicus(97.6%),Agromyces ulmi(97.3%),Agromyces flavus(97.2%), andAgromyces italicus(97.0%), whereas the sequence similarity values with respect to the otherAgromycesspecies with validly published names were between 95.3 and 96.7 %. However, the DNA-DNA hybridization values obtained between strain AK-1Tand other related strains were well below the threshold that is required for the proposal of a novel species. The DNAG+Ccontent of the strain is 71.8 mol%. The above data in combination with the phenotypic distinctiveness of AK-1Tclearly indicate that the strain represents a novel species, for which the nameAgromyces arachidissp. nov. is proposed. The type strain is AK-1T(=MTCC 10524T= JCM 19251T).

Lipid Pattern

A novel halophilic bacterium, designated strain MSS4T, was isolated from the solar salterns of Mesolongi, Greece. The micro-organism, a motile, Gram-stain-positive, aerobic rod, proliferated at salinities of 1.0–4.0 M NaCl, with optimal growth at 2.5 M NaCl. Endospores were not observed. Strain MSS4T showed optimal growth at 37 °C and pH 8.0. The G+C content of its DNA was 47.2 mol%. The polar lipid pattern of strain MSS4T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidic acid and phosphatidylethanolamine. It possessed anteiso-C15 : 0, C18 : 0, C16 : 0 and anteiso-C17 : 0 as the major fatty acids (altogether representing 84.7 % of the total). The predominant isoprenoid quinone was MK-7. The cell-wall peptidoglycan contained meso-diaminopimelic acid. 16S rRNA gene sequence analysis showed that the new isolate has 96.1 % similarity to Bacillus qingdaonensis CM1T and Bacillus aidingensis 17-5T, 95.5 % to Bacillus salarius BH169T and lower similarity to other Bacillus species. These results justify the assignment of strain MSS4T to a novel species within the genus Bacillus, for which the name Bacillus halochares sp. nov. is proposed. The type strain is MSS4T (=LMG 24571T =DSM 21373T).

AbstractA Gram-positive, aerobic, rod-shaped bacterium, designated as strain 1605-214T, was isolated from the blood sample of a patient with cholangitis. Based on its 16S rRNA gene sequence, the strain 1605-214T belonged to the genus Cohnella and exhibited 97.9% sequence identity with Cohnella luojiensis DSM 24270T (GQ214052). DNA–DNA hybridization, digital DNA–DNA hybridization, and average nucleotide identity values between the two species were 23% ± 1.9, 21.1%, and 77.2%, respectively. The cellular fatty acids of strain 1605-214T were mainly comprised of anteiso-C15:0 (36.1%), iso-C16:0 (16.5%), and C16:0 (15.1%). The predominant quinone was menaquinone-7; predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, and aminophospholipid-1. The cell wall peptidoglycan of strain 1605-214T contained meso-diaminopimelic acid. DNA G + C content of strain 1605-214T was 50.6 mol%. 5187 genes out of a total of 5413 (94.6%) were assigned putative functions using eggNOG v5.0. Based on genotypic characteristics and genomic sequence analysis results, strain 1605-214T was confirmed to represent a novel species of genus Cohnella, for which the name Cohnella cholangitidis sp. nov., was proposed.

Strain LU14T, isolated from the roots of Lupinus angustifolius, was characterized using a polyphasic approach. 16S rRNA gene sequence studies showed a similarity of 98·7 % to the corresponding sequence of Kribbella sandramycini DSM 15626T. Chemotaxonomic data gathered for fatty acids, phospholipids, cell-wall peptidoglycan and menaquinones strongly supported the classification of this strain in the genus Kribbella and DNA–DNA hybridization studies suggested that it may represent a novel species. Many physiological features were found that clearly distinguished isolate LU14T from other Kribbella species. Based on the above data, a novel species of the genus Kribbella, Kribbella lupini sp. nov., is proposed with the type strain LU14T (=DSM 16683T=LMG 22957T).
