A Gram-stain-positive, alkaliphilic bacterium, designated EGI 80668T, was isolated from a Tamarix cone soil in Xinjiang, north-west China. Cells were facultatively anaerobic, terminal endospore-forming and motile by means of peritrichous flagella. Colonies were yellowish and the cells showed oxidase-negative and catalase-positive reactions. Strain EGI 80668T grew at pH 8.0–10.0 and with 0–10 % (w/v) NaCl (optimally at pH 9.0 and with 1–2 % NaCl) on marine agar 2216. The predominant menaquinone was MK-7. The major fatty acids were anteiso-C17 : 0 and anteiso-C15 : 0. The cellular polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, four unknown phospholipids and one unknown aminophospholipid. The G+C content of the genomic DNA was 38.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain EGI 80668T was affiliated to the genus Bacillus . The highest 16S rRNA gene sequence similarity between strain EGI 80668T and a member of the genus Bacillus was 96.83 % with Bacillus cellulosilyticus JCM 9156T. A polyphasic taxonomic study based on morphological, physiological, biochemical and phylogenetic data indicated that strain EGI 80668T represents a novel species of the genus Bacillus , for which the name Bacillus tamaricis sp. nov. (type strain EGI 80668T=KCTC 33703T=CGMCC 1.15917T) is proposed.
A novel aerobic, Gram-stain-positive, sporogenous, rod-shaped bacterial strain, 7578-1T, was isolated from ripened Pu’er tea. Based on 16S rRNA gene sequence similarity comparisons, strain 7578-1T was grouped into the genus Bacillus and appeared to be closely related to the type strains Bacillus shackletonii LMG 18435T (98.4 %), Bacillus acidicola DSM 14745T (97.6 %), Bacillus paralicheniformis KACC 18426T (97.2 %) and Bacillus ginsengihumi KCTC 13944T (96.7 %). The fatty acid profile containing the major fatty acids, iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0 supported the allocation of strain 7578-1T to the genus Bacillus . The strain had a cell-wall type A1γ peptidoglycan with meso-diaminopimelic acid as the diagnostic diamino acid. The major menaquinone was MK-7 (95 %). The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, one unidentified phospholipid and one unidentified lipid. The average nucleotide identity values between strain 7578-1T and its most closely related species were 67.8–82.4 % by OrthoANIu analysis. The DNA–DNA relatedness value between strain 7578-1T and the type strains of closely related species were 17–39 %, again indicating that strain 7578-1T represented a novel species in the genus Bacillus . The DNA G+C content of strain 7578-1T was 36.0 mol%. On the basis of the presented polyphasic evidence, strain 7578-1T is considered to represent a novel species of the genus Bacillus , for which we propose the name Bacillus camelliae sp. nov. The type strain is 7578-1T (=CGMCC 1.15374T=KCTC 33845T).
A novel aerobic, Gram-stain-positive, motile, moderately halophilic and coccoid bacterial strain, designated LCB217T, was isolated from a saline-alkali soil in north-western China and identified using a polyphasic taxonomic approach. Growth occurred with 3–15 % (w/v) NaCl (optimum 3–5 %), at 10–45 °C (optimum 30 °C) and at pH 7.0–9.0 (optimum pH 9.0). Strain LCB217T contained MK-7 and MK-8 as the predominant menaquinones and anteiso-C15 : 0, iso-C14 : 0 and iso-C16 : 0 as the major fatty acids. The polar lipids from strain LCB217T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, one unidentified phospholipid, one unidentified aminophospholipid and one unidentified lipid. The peptidoglycan type was A4α (l-Lys–d-Glu). Phylogenetic analysis of the 16S rRNA gene sequence showed that strain LCB217T belonged to the genus Planococcus and was closely related to the type strains Planococcus plakortidis AS/ASP6 (II)T (98.2 % similarity), Planococcus maitriensis S1T (97.7 %) and Planococcus salinarum ISL-16T (97.2 %). The G+C content of the genomic DNA was 49.4 mol%. DNA–DNA relatedness values between strain LCB217T and Planococcus plakortidis AS/ASP6 (II)T, Planococcus maitriensis S1T and Planococcus salinarum ISL-16T were 29.5, 38.1 and 39.5 %, respectively. On the basis of the phenotypic, phylogenetic and genomic data, strain LCB217T represents a novel species of the genus Planococcus , for which the name Planococcus salinus sp. nov. is proposed. The type strain is LCB217T (=CGMCC 1.15685T=KCTC 33861T).
Strain Rs-Y01T was isolated from the gut of the wood-feeding subterranean termite Reticulitermes speratus. Phylogenetic analysis based on 16S rRNA gene sequence indicated that the strain Rs-Y01T belonged to the genus Lactococcus and was most closely related to Lactococcus raffinolactis JCM 5706T with 98.1 % similarity in the 16S rRNA gene, followed by Lactococcus piscium JCM 16647T (97.2 %). Genomic comparisons of strain Rs-Y01T with L. raffinolactis JCM 5706Twere made using the Genome-to-Genome Distance Calculator and average nucleotide identity analysis (values indicated 29.2 and 84.6 %, respectively). Strain Rs-Y01T was a Gram-stain-positive, facultatively anaerobic, non-motile coco-bacilli and formed l-lactic acid. The sugar fermentation and enzyme reactions of strain Rs-Y01T differed from those of other species of the genus Lactococcus . The major cellular fatty acids were summed feature 8 (C18 : 1ω7c/C18 : 1ω6c; 32.0 %), C16 : 0 (29.7 %) and C14 : 0 (18.1 %). Based on these characteristics, strain Rs-Y01T represents a novel species of the genus Lactococcus , for which the name Lactococcus reticulitermitis sp. nov. is proposed. The type strain is Rs-Y01T (=JCM 32106T=DSM 105715T).
