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).

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 novel actinomycete, strain ST1-08T, was isolated from the stem of Stemona sp. in Thailand. The taxonomic position of this isolate was determined by using a polyphasic approach. Strain ST1-08T contained meso-diaminopimelic acid in the cell-wall peptidoglycan, and arabinose and galactose as diagnostic sugars of the whole-cell hydrolysate, which are typical properties of members of the genus Amycolatopsis. Strain ST1-08T grew at 15–40 °C, pH 6–9 and on 5 % (w/v) NaCl. Gelatin liquefaction, starch hydrolysis and skimmed milk peptonization were positive. The strain utilized l-arabinose, d-glucose, glycerol, myo-inositol, d-mannitol and l-rhamnose. The predominant menaquinone was MK-9(H4) and the major cellular fatty acids were iso-C16 : 0 and iso-C15 : 0.The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyl-phosphatidylethanolamine, phosphatidylinositol and phosphatidylglycerol. The 16S rRNA gene sequence analysis revealed that the strain was closely related to Amycolatopsis pretoriensis JCM 12673T (98.99 %) and Amycolatopsis lexingtonensis JCM 12672T (98.87 %). The DNA G+C content of strain ST1-08T was 71.2 mol%. The DNA–DNA relatedness values among strain ST1-08T, A. pretoriensis JCM 12673T and A. lexingtonensis JCM 12672T were lower than 70 %, the cut-off level for assigning strains to the same species. On the basis of phenotypic and genotypic characteristics, strain ST1-08T represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis stemonae is proposed. The type strain is ST1-08T( = JCM 30050T = PCU 339T = TISTR 2278T).

Three Gram-stain-positive strains were isolated from fermented mustard and were rod-shaped, non-motile, asporogenous, facultatively anaerobic, homofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, pheS and rpoA gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence analysis, the type strains of Lactobacillus crustorum (98.7 % similarity), Lactobacillus farciminis (98.9 %) and Lactobacillus mindensis (97.9 %) were the closest neighbours. However, DNA–DNA reassociation values with these strains were less than 50 %. Phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus futsaii sp. nov. is proposed; the type strain is YM 0097T ( = JCM 17355T = BCRC 80278T).

A Gram-stain-negative spirochaete (strain JC202T) was isolated from the gut of the termite Odontotermes obesus (Rambur) from Rann of Kutch, Gujarat, India. This strain was obligately anaerobic, mesophilic, halotolerant and required alkaline conditions for growth. Strain JC202T was resistant to rifampicin and kanamycin, but sensitive to gentamicin, tetracycline, ampicillin and chloramphenicol. Strain JC202T possessed phosphatidylglycerol, diphosphatidylglycerol, glycolipid and six unidentified lipids. C18 : 1ω7c was the predominant cellular fatty acid with significant proportions of C16 : 0, C18 : 1ω9c, C14 : 0, C18 : 0, C16 : 1ω5c, C18 : 1ω5c and C20 : 1ω9c. The DNA G+C content of strain JC202T was 59 mol%. Based on 16S rRNA gene sequence analysis, strain JC202T is considered to belong to the genus Spirochaeta with Spirochaeta sphaeroplastigenens JC133T (100 % similarity), Spirochaeta alkalica Z-7491T (99.92 %), Spirochaeta americana ATCC BAA-392T (99.47 %) and other members of the genus Spirochaeta ( < 93.83 %) as the closest phylogenetic neighbours. However, mean DNA–DNA hydridization values between strain JC202T and S. sphaeroplastigenens JC133T, S. alkalica DSM 8900T ( = Z-7491T) and S. americana DSM 14872T ( = ASpG1T) were 55 ± 2, 22 ± 3 and 32 ± 1 %, respectively. On the basis of physiological, biochemical, chemotaxonomic (including metabolome) and genomic differences from the previously described taxa, strain JC202T is differentiated from other members of the genus Spirochaeta and is considered to represent a novel species, for which the name Spirochaeta odontotermitis sp. nov. is proposed. The type strain is JC202T ( = KCTC 15324T = NBRC 110104T).

Strain NY-2T was able to grow in the presence of 0–23 % (w/v) NaCl and at pH 4.5–10.0 and 5–42 °C; optimum growth was observed with 3–8 % (w/v) total salts and at pH 6.5–8.0 and 28–37 °C. Chemotaxonomic analyses, including fatty acid profiles, menaquinones and polar lipids, supported the affiliation of strain NY-2T to the genus Jeotgalicoccus. The predominant menaquinone of strain NY-2T was menaquinone 7 (MK-7) (100 %) and the major cellular fatty acids were iso-C15 : 0 (49.0 %) and anteiso-C15 : 0 (19.6 %). Cellular polar lipids were phosphatidylglycerol, diphosphatidylglycerol and several unidentified phospholipids. The DNA G+C content of strain NY-2T was 36.8 mol%. Based on 16S rRNA gene sequence analysis, strain NY-2T formed a coherent cluster with Jeotgalicoccus marinus JSM 076033T, Jeotgalicoccus halotolerans YKJ-101T and Jeotgalicoccus psychrophilus YKJ-115T. Phylogenetic analysis, DNA–DNA relatedness data, phenotypic characteristics and chemotaxonomic data indicated that strain NY-2T (=CCTCC AB 208288T =JCM 15687T) should be classified as the type strain of a novel species of the genus Jeotgalicoccus, for which the name Jeotgalicoccus huakuii sp. nov. is proposed.
