Aerobic, endospore-forming bacteria that are attributed to the genus Bacillus or related genera constitute a hazard to the quality of gelatin. During repetitive extragenic palindromic DNA (rep)-PCR screening of gelatin isolates, a group of five isolates (group 1) and a group of 66 isolates (group 2) that did not match any pattern in our database were found. On the basis of 16S rDNA sequence analysis, representative strains of the different rep-PCR fingerprint types of group 1 were shown to be related most closely to Anoxybacillus species, but with sequence similarity of <97 %. Likewise, representative strains of group 2 were shown to be related most closely to Bacillus species, with 16S rDNA sequence similarity of <97 %. DNA–DNA reassociation values of isolates that displayed the most divergent rep-PCR profiles revealed that strains within each group belonged to a single species, according to recommendations for species delineation. A mean fatty acid profile could be calculated for each group. Isolates within a single group had similar patterns of results in API and other phenotypic tests; no correlation of patterns of results with rep-PCR groups was seen. Physiological characterization of group 1 isolates allows their distinction from other Anoxybacillus species. Despite the weak reaction of group 2 isolates in API tests, physiological characterization allows distinction between Bacillus species that react weakly in API tests. Two novel species are therefore proposed, with the names Anoxybacillus contaminans sp. nov. (type strain, LMG 21881T=DSM 15866T) and Bacillus gelatini sp. nov. (type strain, LMG 21880T=DSM 15865T).

16S Rdna Sequence

On the basis of phenotypic and genotypic characteristics and 16S rRNA gene sequence analysis, novel species belonging to the genera Sphingomonas and Brevundimonas were identified from samples taken from the Russian space laboratory Mir. Strain A1-18T was isolated from the air. 16S rDNA sequence analysis showed that strain A1-18T formed a coherent cluster with Sphingomonas sanguinis, Sphingomonas parapaucimobilis, Sphingomonas paucimobilis and Sphingomonas roseiflava with sequence similarity of 97·5–98·6 %. Similar to other Sphingomonas species, the G+C content was 66·1 mol%, but DNA–DNA hybridization rates at optimal temperatures among these related species were only 24·7–51·7 %. Strain A1-18T can be differentiated biochemically from related species. Strain W1-2BT was isolated from condensation water. It forms a distinct lineage within the genus Brevundimonas, forming a coherent cluster with Brevundimonas vesicularis, Brevundimonas aurantiaca and Brevundimonas intermedia. 16S rDNA sequence similarities were 98·6–99·5 % and the G+C content was 66·5 mol%, similar to other Brevundimonas species, but DNA–DNA relatedness was only 50·2–54·8 %. Strain W1-2BT also showed some differential biochemical properties from its related species. A series of polyphasic taxonomic studies led to the proposal of two novel species, Sphingomonas yabuuchiae sp. nov. (type strain A1-18T=GTC 868T=JCM 11416T=DSM 14562T) and Brevundimonas nasdae sp. nov. (type strain W1-2BT=GTC 1043T=JCM 11415T=DSM 14572T).

Phylogenetic Level

A Gram-positive, molinate-degrading bacterium, strain ON4T (=DSM 13485T=LMG 21909T), was isolated from a mixed bacterial culture able to mineralize the herbicide molinate. The strain was strictly aerobic, oxidase- and catalase-positive and non-acid-fast, with a growth temperature of 10–41 °C. It contained the major menaquinone MK-9 and a cell-wall peptidoglycan based on d-ornithine. 16S rDNA sequence analysis revealed that the strain formed a distinct line of descent in the family Microbacteriaceae, showing the highest 16S rDNA similarity (∼95 %) to members of the genus Curtobacterium and ‘Brevibacterium helvolum’ DSM 20419 (=ATCC 13715). The latter was reported to have the cell-wall peptidoglycan type B2γ and the major menaquinone MK-9, which are typical of Clavibacter, but it is clearly separated from this genus at the phylogenetic level. Based on low values of 16S rDNA sequence similarity to previously described genera and their distinctive phenotypic characteristics, it is proposed that strains ON4T and ‘B. helvolum’ DSM 20419 be classified as two novel genera and species, with the respective names Gulosibacter molinativorax gen. nov., sp. nov. and Pseudoclavibater helvolus gen. nov., sp. nov.

Four Gram-positive bacteria, strains A1-17BT, A1-22T, A1-3T and A1-8, isolated from the air in the Russian space laboratory Mir, were subjected to a polyphasic taxonomic study. Phylogenetic analysis of the bacteria based on their 16S rDNA sequence showed that they belong to the genera Rothia (A1-17BT), Rhodococcus (A1-22T) and Arthrobacter (A1-3T and A1-8). Morphological, physiological, chemotaxonomic and genomic characteristics supported the assignments of these strains to these genera, but they could not be classified as any existing species within each respective genus. 16S rDNA similarity values between strain A1-17BT and its neighbours, Rothia dentocariosa genomovar II, Rothia dentocariosa, Rothia mucilaginosa and Rothia nasimurium, were respectively 99·8, 98·0, 96·4 and 95·4 %. Polyphasic taxonomic evidence indicated that strain A1-17BT should be categorized together with the unofficially named Rothia dentocariosa genomovar II, but clearly differentiated them from the established species of the genus Rothia. Strain A1-22T formed a coherent cluster with Rhodococcus erythropolis, Rhodococcus globerulus, Rhodococcus marinonascens and Rhodococcus percolatus in 16S rDNA sequence analysis, but DNA–DNA relatedness values were only 45·5, 35·3, 18·9 and 21·9 %. Strains A1-3T and A1-8 shared 99·9 % 16S rDNA sequence similarity, and strain A1-3T showed the highest level of 16S rDNA similarity, 96·6 %, to Arthrobacter polychromogenes. Contrasting biochemical characteristics were also identified. Finally, as a result of the polyphasic taxonomic study, three of the strains are proposed as type strains of novel species: Rothia aeria sp. nov. (A1-17BT=GTC 867T=JCM 11412T=DSM 14556T), Rhodococcus baikonurensis sp. nov. (A1-22T=GTC 1041T=JCM 11411T=DSM 44587T) and Arthrobacter russicus sp. nov. (A1-3T=GTC 863T=JCM 11414T=DSM 14555T).

16S Rdna Sequence Analysis

A group of 42 isolates were isolated from the soil of several disused hay fields, in the Drentse A agricultural research area (The Netherlands), that were taken out of production at different times. The group represents hitherto-uncultured Bacillus lineages that have previously been found, by a non-cultural method, to be predominant in soil. The strains were subjected to a polyphasic taxonomic study, including (GTG)5-PCR, 16S rDNA sequence analysis, DNA–DNA hybridizations, DNA base-ratio determination, fatty acid analysis and morphological and biochemical characterization. By comparing the groupings obtained by (GTG)5-PCR and 16S rDNA sequence analysis, six clusters of similar strains could be recognized. A DNA–DNA relatedness study showed that these clusters represented five novel genospecies. Further analysis supported the proposal of five novel species in the genus Bacillus, namely Bacillus novalis sp. nov. (type strain IDA3307T=R-15439T=LMG 21837T=DSM 15603T), Bacillus vireti sp. nov. (type strain IDA3632T=R-15447T=LMG 21834T=DSM 15602T), Bacillus soli sp. nov. (type strain IDA0086T=R-16300T=LMG 21838T=DSM 15604T), Bacillus bataviensis sp. nov.

Group 1

Two novel species belonging to the genus Shewanella are described on the basis of a polyphasic taxonomic approach. A total of 40 strains of Gram-negative, psychrotolerant, H2S-producing bacteria were isolated from marine fish (cod and plaice) caught in the Baltic Sea off Denmark. Strains belonging to group 1 (seven strains) were a lactate-assimilating variant of Shewanella morhuae with a G+C content of 44 mol%. The strains of group 2 (33 strains) utilized lactate, N-acetylglucosamine and malate but did not produce DNase or ornithine decarboxylase. Their G+C content was 47 mol%. Phylogenetic analysis of the 16S rRNA gene sequence data placed the two novel species within the genus Shewanella. Group 1 showed greatest sequence similarity with S. morhuae ATCC BAA-1205T (99.9 %). However, gyrB gene sequence analysis and DNA–DNA hybridization differentiated these isolates from S. morhuae, with 95.6 % sequence similarity and less than 57 % DNA relatedness, respectively. Group 2 strains shared more than 99 % 16S rRNA gene sequence similarity with the type strains of Shewanella colwelliana and Shewanella affinis, but gyrB sequence similarity (~85 %) and the results of DNA hybridization (~28 %) indicated that the new isolates represented a novel species. Furthermore, when compared to each other, the type strains of S. colwelliana and S. affinis had almost identical gyrB sequences and significantly high DNA reassociation values (76–83 %), indicating that they belonged to the same species. Based on the conclusions of this study, we propose the novel species Shewanella glacialipiscicola sp. nov. (type strain T147T=LMG 23744T=NBRC 102030T) for group 1 strains and Shewanella algidipiscicola sp. nov. (type strain S13T=LMG 23746T=NBRC 102032T) for group 2 strains, and we propose that Shewanella affinis as a later heterotypic synonym of Shewanella colwelliana.

During a survey of potato scab pathogens in China from 2003 to 2012, a new pathogen was found in Shanxi and Neimenggu provinces. The incidence was approximately 20% of all recovered strains. The lesions caused by the pathogen were slightly raised and similar to those caused by Streptomyces scabies (3). Lesions were excised (approximately 10 mm3) from 40 infected tubers, surface-disinfested with 0.3% NaOCl for 30 s, rinsed in sterile water three times, cut into 5 mm3, then sliced into 1-mm pieces, and plated on water agar amended with ampicillin (50 μg/ml). Plates were incubated at 28°C in the dark for 4 days. The spores of Streptomyces sp. strains growing from the tuber pieces were collected from single bacterial colonies and cultured on oatmeal agar. To fulfill Koch's postulates, one strain, CPS-2, was grown at 28°C for 10 days and the spores were washed from the plates as inoculum. One hundred milliliters of inoculum (1 × 105 CFU/ml) was mixed with autoclaved soil and vermiculite (1:1) in each pot (15 cm in diameter). Cut tubers were planted in the pots (potato cv. Favorita, one plant per pot, five replicates) and grown under greenhouse conditions (22 ± 5°C). Typical common scab symptoms consisting of small, brown, raised lesions developed on potato tubers 12 weeks after planting. The same strain was re-isolated from the lesions of the new scabby tubers. Non-inoculated plants, treated as described above, but without strain CPS-2, remained healthy. The CPS-2 strain was identified based on morphological and physiological characterization and 16S rDNA sequence. On yeast-malt extract agar, the test strain produced grayish-white aerial hypha, reddish brown substrate mycelium and pigments, and loose spiral spore chains. Spores were smooth and were 0.8 to 0.9 × 1.1 to 1.2 μm in size (diameter and length). The ability of the strain to use single sources of carbon and nitrogen was verified according to the International Streptomyces project (4). The strain grew in media supplemented with L-arabinose, D-fructose, D-glucose, rhamnose, raffinose, meso-inositol, sucrose, and D-xylose, but not D-mannitol. It used L-hydroxyproline, L-methionine, and L-histidine, and produced melanin on tyrosine and peptone yeast extract agar. The strain did not grow at a pH less than 5.0 and was sensitive to streptomycin (20 μg/ml), phenol (0.1%), and crystal violet (0.5 μg/mL), but not to penicillin (10 IU/ml). The strain also produced hydrogen sulfide. The biological characteristics of strain CPS-2 were in accord with Streptomyces galilaeus. CPS-2 produced thaxtomin A in oatmeal liquid medium and the txt AB gene fragment was successfully amplified using specific primers (2). The 16S rDNA sequence of CPS-2 was amplified by PCR with primers 16S1-F: 5′-CATTCACGGAGAGTTTGATCC-3′ and 16S1-R: 5′-AGAAAGGAGGTGATCCAGCC-3′ (1) and sequenced. A BLAST search of the 16S rDNA sequence for CPS-2 was conducted using the NCBI GenBank database, resulting in 99.8% similarity to S. galilaeus (NR_040857). The 16S rDNA sequence for CPS-2 (1,388 bp) was deposited in GenBank (AY621378). To our knowledge, this is the first report of S. galilaeus causing common scab of potato in China. References: (1) R.

Spartium witches'-broom (SpaWB), buckthorn witches'-broom (BWB) and allocasuarina yellows (AlloY) are witches'-broom and yellows diseases of Spartium junceum (Spanish broom), Rhamnus catharticus (buckthorn) and Allocasuarina muelleriana (Slaty she-oak), respectively. These diseases are associated with distinct phytoplasmas. The SpaWB, BWB and AlloY phytoplasmas share <97·5 % 16S rDNA sequence similarity with each other and with other known phytoplasmas, including the closely related phytoplasmas of the apple proliferation group. Also, the SpaWB, BWB and AlloY phytoplasmas each have a different natural plant host. Based on their unique properties, it is proposed to designate the mentioned phytoplasmas as novel ‘Candidatus’ species under the names ‘Candidatus Phytoplasma spartii’, ‘Candidatus Phytoplasma rhamni’ and ‘Candidatus Phytoplasma allocasuarinae’, respectively.

Seven strains of aerobic, endospore-forming bacteria were found in soil taken from an active fumarole on Lucifer Hill, Candlemas Island, South Sandwich archipelago, Antarctica, and four strains were from soil of an inactive fumarole at the foot of the hill. Amplified rDNA restriction analysis, 16S rDNA sequence comparisons, SDS-PAGE and routine phenotypic tests support the proposal of two novel species of Paenibacillus, Paenibacillus cineris sp. nov. and Paenibacillus cookii sp. nov., the type strains of which are LMG 18439T (=CIP 108109T) and LMG 18419T (=CIP 108110T), respectively. A further strain, isolated from a gelatin-production process, showed more than 99 % 16S rDNA sequence similarity to the proposed P. cookii type strain and, although the gelatin isolate was atypical when compared with the fumarole isolates by repeated element primed-PCR, SDS-PAGE and phenotypic analyses, it was shown by DNA–DNA reassociation studies to belong to the same species. Strains of P. cookii produce spreading growth with motile microcolonies. Both species produce swollen sporangia that are typical for the genus, they both show 97·6 % 16S rDNA sequence similarity to Paenibacillus azoreducens, they have 51·5–51·6 mol% G+C in their DNA and their major fatty acid is anteiso-C15 : 0; however, fatty acids C16 : 0 and anteiso-C17 : 0 represent, respectively, 18 and 10 % of the total in P. cineris, but 11 and 20 % in P. cookii.

A 4-chlorophenol-degrading bacterial strain, formerly designated as a strain of Comamonas testosteroni, was reclassified as a member of the genus Herbaspirillum based on its phenotypic and chemotaxonomic characteristics, as well as phylogenetic analysis using 16S rDNA sequences. Phylogenetic inference based on 16S rDNA sequences showed that strain CPW301T clusters in a phylogenetic branch that contains Herbaspirillum species. 16S rDNA sequence similarity of strain CPW301T to species of the genus Herbaspirillum with validly published names is in the range 98·7–98·9 %. Despite the considerably high 16S rDNA sequence similarity, strain CPW301T could be distinguished clearly from type strains of Herbaspirillum species with validly published names by DNA–DNA relatedness values, which were <15·7 %. The genomic DNA G+C content of strain CPW301T is 61·3 mol%. The predominant ubiquinone is Q-8 and the major cellular fatty acids are C16 : 0 and cyclo-C17 : 0. The strain does not fix nitrogen and is not plant-associated. It is an aerobic rod with one unipolar flagellum. On the basis of these characteristics, a novel Herbaspirillum species, Herbaspirillum chlorophenolicum sp. nov., is proposed. The type strain of the novel species is strain CPW301T (=KCTC 12096T=IAM 15024T).

A curved, ring-like bacterium, strain AS 1.1761T, isolated from the roots of Spartina anglica, was studied by a polyphasic approach. According to phylogenetic analysis, strain AS 1.1761T belongs to the genus Ancylobacter, with 99·21 % 16S rDNA sequence similarity to Ancylobacter aquaticus, the only species described so far in this genus. However, strain AS 1.1761T had no significant DNA–DNA binding with the type strain of A. aquaticus. In addition, strain AS 1.1761T differed from A. aquaticus in many phenotypic features. Based on molecular and phenotypic data, a novel species, Ancylobacter rudongensis sp. nov., is proposed. The type strain is AS 1.1761T (=JCM 11671T).
