投稿须知/期刊简介:
International Journal of Systematic and Evolutionary Microbiology (IJSEM), formerly International Journal of Systematic Bacteriology (IJSB), is the official journal of record for new bacterial taxa. Now in its 51st year (before 1966 it was known as the International Bulletin of Bacteriological Nomenclature and Taxonomy), the journal is the cornerstone of the ever-expanding field of microbial systematics. IJSEM publishes papers dealing with all phases of the systematics of bacteria, yeasts and yeast-like organisms, including taxonomy, nomenclature, identification, phylogeny, evolution, biodiversity, characterization and culture preservation. Its scope covers phylogenetic and evolutionary aspects of all micro-organisms, including the protists such as protozoa and algae, and will now also publish molecular environmental papers with a strong systematics content. Its international Editorial Board ensures the highest standards of peer review.

International Journal of Systematic and Evolutionary Microbiology, formerly International Journal of Systematic Bacteriology (IJSB), is the official journal of record for novel prokaryotic taxa. It is the official publication of the International Committee on Systematics of Prokaryotes and the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies. International Journal of Systematic and Evolutionary Microbiology is published by the Microbiology Society, a learned society that promotes microbiology at all levels.

Clostridium hiranonis sp. nov., a human intestinal bacterium with bile acid 7alpha-dehydroxylating activity.
:The Clostridium-like organisms TO-931T and HD-17, isolated from human faeces, have high levels of bile acid 7alpha-dehydroxylating activity. Sequencing of their 16S rDNA demonstrated that they belong to cluster XI of the genus Clostridium and that they represent a new and distinct line of descent. Clostridium bifermentans and Clostridium sordellii in cluster XI also possess bile acid 7alpha-dehydroxylating activity. DNA-DNA hybridization experiments with the isolates, TO-931T and HD-17, and C bifermentans and C. sordellii revealed that the isolates are a single species distinct from C. bifermentans and C sordellii. On the basis of phylogenetic analysis, using 16S rDNA sequences, and DNA-DNA hybridization analysis, it is concluded that strains TO-931T and HD-17 are members of a new species of the genus Clostridium, for which the name Clostridium hiranonis is proposed. The type strain is strain TO-931T (= JCM 10541T = DSM 13275T).

Phylogeny of the filamentous bacterium 'Nostocoida limicola' III from activated sludge.
:Five strains of the filamentous bacterium 'Nostocoida limicola' III were successfully isolated into pure culture from samples of activated sludge biomass from five plants in Australia. 16S rRNA gene sequence analyses showed that all isolates were members of the Planctomycetales, most closely related to Isosphaera pallida, but they differed phenotypically from this species in that they did not glide and were not thermotolerant. The ultrastructure of these 'N. limicola' III isolates was also consistent with them being Planctomycetales, in that they possessed complex intracellular membrane systems compartmentalizing the cells. However, the arrangements of these intracellular membranes differed between isolates. These data confirm that 'N. limicola' III is phylogenetically unrelated to both 'N. limicola' I and 'N. limicola' II, activated sludge filamentous bacteria which share morphological features in common with 'N. limicola' III and which have been presumed historically to be the same or very similar bacteria.

Desulfosporosinus meridiei sp. nov., a spore-forming sulfate-reducing bacterium isolated from gasolene-contaminated groundwater.
:Eight strains of spore-forming, sulfate-reducing bacteria, isolated from groundwater contaminated with motor fuel [mostly benzene, toluene ethylbenzene and xylene (BTEX) compounds] in sandy soil near Perth, Australia, were closely related to Desulfosporosinus (previously Desulfotomaculum) orientis DSM 765T (95.3-97.3% 16S rDNA sequence similarity). Whole-cell fatty acids were dominated by even-carbon, straight-chain saturated and mono-unsaturated fatty acids, in particular 16:0, 16:1cis9, 14:0 and 18:1cis11. The strains grew at temperatures between 4 and 42 degrees C and in medium containing up to 4% NaCl. The eight strains clustered into two main groups based on phylogeny, randomly amplified polymorphic DNA (RAPD)-PCR patterns and nutritional characteristics. Representatives of the two groups, strain S5 (group A) and strain S10T (group B) had 81% DNA-DNA homology with each other and therefore should be accommodated in the same species. Strain S10T had less than 38% homology with Desulfosporosinus orientis DSM 765T, the most closely phylogenetically related type strain available. The new strains were distinguished from Desulfosporosinus orientis DSM 765T by different banding patterns in a RAPD-PCR, and phenotypically by their inability to utilize fumarate as a carbon and energy source with sulfate as the electron acceptor and by their lower tolerance to NaCl. The DNA G+C contents were 46.8 and 46.9 mol% for strains S5 and S10T, respectively (Desulfosporosinus orientis DSM 765T 45.9 mol%). It is proposed that these new strains be placed in a new species of the genus Desulfosporosinus. The name Desulfosporosinus meridiei is proposed, with strain S10T as the type strain (= DSM 13257T = NCIMB 13706T).

Change of the names Haloanaerobiales, Haloanaerobiaceae and Haloanaerobium to Halanaerobiales, Halanaerobiaceae and Halanaerobium, respectively, and further nomenclatural changes within the order Halanaerobiales.
:A formal proposal is made to rename the order Haloanaerobiales as Halanaerobiales, the family Haloanaerobiaceae as Halanaerobiaceae, the genera Haloanaerobium and Haloanaerobacter as Halanaerobium and Halanaerobacter, respectively, and to change the specific epithets of Halanaerobium acetoethylicum, Halanaerobacter lacunaris, Halocella cellulolytica and Halanaerobium chitinovorans to acetethylicum, lacunarum, cellulosilytica and chitinivorans, respectively. These changes are required in view of Rule 61, Appendix 9, of the Bacteriological Code.

Thermoanaerobacter subterraneus sp. nov., a novel thermophile isolated from oilfield water.
:A new thermophilic, anaerobic glucose-fermenting, Gram-positive, rod-shaped bacterium, designated strain SEBR 7858T, was isolated from an oilfield water sample. Under optimal conditions on a glucose-containing medium (3% NaCl, 65 degrees C and pH 7.5), the generation time was 2.5 h. No growth occurred at 35 or 80 degrees C, nor at pH 5..5 or 9.0. Strain SEBR 7858T possessed lateral flagella. Spores were undetected but heat-resistant forms were present. Strain SEBR 7858T fermented a range of carbohydrates to acetate, L-alanine, lactate, H2 and CO2. The isolate reduced thiosulfate and elemental sulfur, but not sulfate or sulfite to sulfide. In the presence of thiosulfate, the ratio of acetate produced per mole of glucose consumed increased, suggesting a shift in the use of electron acceptors during carbohydrate metabolism. The DNA G+C content was 41 mol%. Based on 16S rRNA gene sequence analysis, the strain was almost equidistantly related to all members of the genus Thermoanaerobacter (mean similarity 92%). Based on phenotypic, genomic and phylogenetic characteristics, strain SEBR 7858T was clearly different from all members of the genus Thermoanaerobacter and was therefore designated as a new species, Thermoanaerobacter subterraneus sp. nov. The type strain is SEBR 7858T (= CNCM 1-2383T, DSM 13054T).
