Lactobacillus uvarum sp. nov.--a new lactic acid bacterium isolated from Spanish Bobal grape must

Five strains isolated from grape musts in Spain in 1997, have been characterized by several molecular techniques, and three of them have been identified as pertaining to a new species. All strains are Gram-positive rods, aerotolerant and homofermentative bacteria that do not exhibit catalase activity. Phylogenetic analysis based on 16S rRNA gene sequences placed these strains within the genus Lactobacillus, closely related to Lactobacillus mali. DNA-DNA hybridization experiments confirmed that strain 71 belongs to the lately described species L. satsumensis, strain 88 belongs to L. mali and the other three isolates have an independent status at species level. Restriction analysis of the amplified 16S rRNA gene (16S-ARDRA), internal spacer region (ISR) analysis, random amplified polymorphism DNA (RAPD) and ribotyping were performed in order to establish genotypic similarities and differences between the new species and their closest species. The three isolates can be genetically differentiated from their closest relatives by RAPD analysis and ribotyping. Phenotypically, they can be distinguished by several traits such as their ability to grow at pH 3.3 and NaCl 5% (w/v) and by certain carbohydrate fermentations. The name L. uvarum sp. nov. is proposed. The type strain is 8T (=DSM 19971T = colección espa?ola de cultivos tipo (CECT) 7335T).     

Arsukibacterium ikkense gen. nov., sp. nov, a novel alkaliphilic, enzyme-producing gamma-Proteobacterium isolated from a cold and alkaline environment in Greenland

A novel aerobic, Gram-negative, non-pigmented bacterium, GCM72(T), was isolated from the alkaline, low-saline ikaite columns in the Ikka Fjord, SW Greenland. Strain GCM72(T) is a motile, non-pigmented, amylase- and protease-producing, oxidase-positive, and catalase-negative bacterium, showing optimal growth at pH 9.2-10.0, at 15 degrees C, and at 3% (w/v) NaCl. Major fatty acids were C(12:0) 3-OH (12.2+/-0.1%), C(16:00) (18.0+/-0.1%), C(18:1)omega7c (10.7+/-0.5%), and summed feature 3 comprising C(16:1)omega7c and/or iso-C(15:0) 2-OH (36.3+/-0.7%). Phylogenetic analysis based on 16S rRNA gene sequences showed that isolate GCM72(T) was most closely related to Rheinheimera baltica and Alishewanella fetalis of the gamma-Proteobacteria with a 93% sequence similarity to both. The G+C content of DNA isolated from GCM72(T) was 49.9mol% and DNA-DNA hybridization between GCM72T and R. baltica was 9.5%. Fatty acid analysis and G+C content supports a relationship primarily to R. baltica, but several different features, such as a negative catalase-response and optimal growth at low temperature and high pH, together with the large phylogenetic distance and low DNA similarity to its closest relatives, lead us to propose a new genus, Arsukibacterium, gen. nov., with the new species Arsukibacterium ikkense sp. nov. (type strain is GCM72(T)).     

Paracoccus bengalensis sp. nov., a novel sulfur-oxidizing chemolithoautotroph from the rhizospheric soil of an Indian tropical leguminous plant

Paracoccus versutus-like isolates from the rhizosphere of Clitoria ternatea, a slender leguminous herb (family--Papilionaceae), found ubiquitously in waste places and village forests of the Lower Gangetic plains of India, presented a case of graduated infraspecific variation that was capped by the identification of a new species Paracoccus bengalensis (type strain JJJ(T) = LMG 22700(T) = MTCC 7003(T)). The diverged phenetic and genetic structure of these sulfur-oxidizing chemolithoautotrophs presented a case of apparent nonconformity of 16S rRNA gene sequence similarities with results of DNA-DNA hybridization. Despite high 16S rRNA gene sequence similarity with P. versutus one of the newly isolated strains, viz., JJJ(T) was identified as a new species of Paracoccus by virtue of its explicitly low DNA-DNA hybridization (42-45%) with the type strain of the closest species P. versutus (), distinct G + C content (65.3 mol%), physiological and biochemical differences amounting to <60% phenetic similarity with strains of P. versutus as well as new isolates akin to the species. The newly described species also had a unique fatty acid profile that was distinguished by the absence of 18:1 omega9c, unique possession of Summed feature 3 (16:1omega7c & 15:0 iso 2-OH), 19:0 10 methyl, and a much higher concentration of 19:0 cycloomega8c.     

Lactobacillus alvi sp. nov., isolated from the intestinal tract of chicken

Strain R54(T) was isolated from the gizzard of hens. The isolate was Gram-positive, facultative anaerobic, gas-forming, catalase-negative, nonmotile, nonspore-forming and short-rod-shaped. The optimal temperature for growth was 40 °C and the DNA G+C content was 42.7 mol%. The 16S rRNA gene sequences similarity showed that strain R54(T) was most closely related to Lactobacillus ingluviei LMG 20380(T) (97.5%), followed by Lactobacillus coleohominis CIP 106820(T) (96.1%), Lactobacillus secaliphilus DSM 17896(T) (95.6%) and Lactobacillus gastricus LMG 22113(T) (95.4%). The DNA-DNA relatedness between strain R54(T) and L. ingluviei LMG 20380(T) , was 43.3%. The predominant cellular fatty acids of strain R54(T) were C(18:1 ω9c) (64.9%) and C(16:0) (20.0%), and the major polar lipid group was phospholipids. On the basis of polyphasic taxonomy approach, strain R54(T) represents a novel species of the genus Lactobacillus, for which the name Lactobacillus alvi sp. nov. is proposed (type strain R54(T) = KCCM 90099(T) = JCM 17644(T)).     

Stappia alba sp. nov., isolated from Mediterranean oysters

Three bacterial strains isolated from oysters recovered at the Spanish Mediterranean coast have been phenotypically and genetically characterized. The results of the phylogenetic analysis based on almost complete 16S rDNA sequences clustered all three strains together with 99.9% average sequence similarity and situated them in the neighbourhood of the genera Stappia, Roseibium and Pannonibacter, Stappia aggregata being their closest neighbour with sequence similarities between 98.8% and 98.9%. DNA-DNA hybridization experiments using DNA of strains 5OM6T and S. aggregata CECT 4269T as reference DNAs confirmed the independent status at species level of the oyster isolates. Phenotypically, they can be distinguished from the closest relatives by the ionic requirements, growth temperatures and use of carbon compounds. We propose these oyster strains constitute a new species of Stappia, for which the name Stappia alba sp. nov. has been chosen, and strain 5OM6T (= CECT 5095T = CIP 108402T) as its type strain.     

Identification of lactic acid bacteria from fermented tea leaves (miang) in Thailand and proposals of Lactobacillus thailandensis sp. nov., Lactobacillus camelliae sp. nov., and Pediococcus siamensis sp. nov

Eighteen rod-shaped homofermentatives, six heterofermentatives, and a coccal homofermentative lactic acid bacteria were isolated from fermented tea leaves (miang) produced in the northern part of Thailand. The isolates were placed in a monophyletic cluster consisting of Lactobacillus and Pediococcus species. They were divided into seven groups by phenotypic and chemotaxonomic characteristics, DNA-DNA similarity, and 16S rRNA gene sequences. Groups I to VI belonged to Lactobacillus and Group VII to Pediococcus. All of the strains tested produced DL-lactic acid but those in Group IV produced L-lactic acid. The strains tested in Groups I, II and V had meso-diaminopimelic acid in the cell wall. Six strains in Group I were identified as Lactobacillus pantheris; five strains in Group II as Lactobacillus pentosus; and four strains in Group V as Lactobacillus suebicus. Two strains in Group VI showed high DNA-DNA similarity for each other and MCH4-2 was closest to Lactobacillus fermentum CECT 562(T) with 99.5% of 16S rRNA gene sequence similarity. Five strains in Group III are proposed as Lactobacillus thailandensis sp. nov., and MCH5-2(T) (BCC 21235(T)=JCM 13996(T)=NRIC 0671(T)=PCU 272(T)) is the type strain which has 49 mol% G+C of DNA. Two strains in Group IV are proposed as Lactobacillus camelliae sp. nov., and the type strain is MCH3-1(T) (BCC 21233(T)=JCM 13995(T)=NRIC 0672(T)=PCU 273(T)) which has 51.9 mol% G+C of DNA. One strain in Group VII is proposed as Pediococcus siamensis sp. nov., and MCH3-2(T) (BCC 21234(T)=JCM 13997(T)=NRIC 0675(T)=PCU 274(T)) is the type strain which has 42 mol% G+C of DNA.     

Lactobacillus oligofermentans sp. nov., associated with spoilage of modified-atmosphere-packaged poultry products

Unidentified lactic acid bacterium (LAB) isolates which had mainly been detected in spoiled, marinated, modified atmosphere packaged (MAP) broiler meat products during two previous studies, were identified and analyzed for their phenotypic properties and the capability to produce biogenic amines. To establish the taxonomic position of these isolates, 16S rRNA gene sequence analysis, numerical analysis of ribopatterns, and DNA-DNA hybridization experiments were done. Unexpectedly for a meat-spoilage-associated LAB, the strains utilized glucose very weakly. According to the API 50 CHL test, arabinose and xylose were the only carbohydrates strongly fermented. None of the six strains tested for production of histamine, tyramine, tryptamine, phenylethylamine, putrescine, and cadaverine were able to produce these main meat-associated biogenic amines in vitro. The polyphasic taxonomy approach showed that these strains represent a new Lactobacillus species. The six isolates sequenced for the 16S rRNA encoding genes shared the highest similarity (95.0 to 96.3%) with the sequence of the Lactobacillus durianis type strain. In the phylogenetic tree, these isolates formed a distinct cluster within the Lactobacillus reuteri group, which also includes L. durianis. Numerical analyses of HindIII-EcoRI ribotypes placed all isolates together in a cluster with seven subclusters well separated from the L. reuteri group reference strains. The DNA-DNA hybridization levels between Lactobacillus sp. nov. isolates varied from 67 to 96%, and low hybridization levels (3 to 15%) were obtained with the L. durianis type strain confirming that these isolates belong to the same species different from L. durianis. The name Lactobacillus oligofermentans sp. nov. is proposed, with strain LMG 22743T (also known as DSM 15707T or AMKR18T) as the type strain.

Taxonomic note "Lactobacillus pastorianus" (Van Laer, 1892) a former synonym for Lactobacillus paracollinoides

"Lactobacillus pastorianus" (Van Laer, 1892) is not a validly described species and is not included in the Approved List of Bacterial Names. The strain is available in multiple culture collections as Lactobacillus sp. DSM 20197, L. brevis ATCC 8291, "L. pastorianus" CECT 5926, L. brevis JCM 1113, and "L. pastorianus" LMG 11990. Nearly identical 16S rRNA sequences and protein encoding genes for 6-phosphogluconate dehydrogenase (99.9%) revealed this strain as L. paracollinoides. A 16S-23S rRNA intergenic spacer region-based PCR assay did not differentiate "L. pastorianus" DSM 20197 from L. paracollinoides DSM 15502(T). Highly similar RAPD profiles differentiated both strains below species level.     

Characterisation of the microbiota of rice sourdoughs and description of Lactobacillus spicheri sp. nov

The microbiota of two industrially processed rice sourdoughs was characterised by bacteriological culture in combination with PCR-denaturing gradient gel electrophoresis (DGGE) and 16S/28S rDNA sequence analysis. Rice sourdough I was continuously propagated for several years by back-slopping every week, whereas sourdough II was processed by using a commercial starter culture and back-slopping daily for three days. In rice sourdough II Candida krusei and Saccharomyces cerevisiae as well as Lactobacillus fermentum, Lactobacillus gallinarum, Lactobacillus kimchii, Lactobacillus plantarum, and Lactobacillus pontis dominated at the first day of fermentation. RAPD analysis of lactobacilli revealed identical profiles for each of the species except for L. fermentum and L. pontis indicating the presence of different strains. Fluctuations within the LAB community during fermentation were monitored by PCR-DGGE. L. pontis decreased in numbers over time and L. curvatus became dominant after 3 days of fermentation. Rice sourdough I contained S. cerevisiae, Lactobacillus paracasei (present with three different RAPD types), Lactobacillus paralimentarius, and a Lactobacillus strain which could not be allotted to any valid species. Phylogenetic analysis based on 16S rDNA sequences revealed Lactobacillus brevis as the closest relative (97.3% sequence similarity). Differences in some phenotypic characteristics and DNA-DNA relatedness indicated that the strain represents a new Lactobacillus species, for which the name Lactobacillus spicheri is proposed.     

Taxonomic study of the Lactobacillus acidophilus group, with recognition of Lactobacillus gallinarum sp. nov. and Lactobacillus johnsonii sp. nov. and synonymy of Lactobacillus acidophilus group A3 (Johnson et al. 1980) with the type strain of Lactobacillus amylovorus (Nakamura 1981).

Biochemical properties and DNA-DNA reassociation studies of Lactobacillus acidophilus strains isolated from humans and animals indicate that these include six genomospecies. Two new species can be differentiated from the established species of the genus Lactobacillus: L. gallinarum sp. nov. (type strain, ATCC 33199) and L. johnsonii sp. nov. (type strain, ATCC 33200). Furthermore, it was clarified that L. acidophilus group A3 (Johnson et al. 1980) is synonymous with L. amylovorus.     

Characterization of Lactobacillus sakei by the type of stereoisomers of lactic acid produced

Lactobacillus sakei strains were characterized by the shift of the type of stereoisomers of lactic acid produced in the presence of 50 mM sodium acetate in a medium. Of 27 Lactobacillus sakei strains studied, 20 strains showed high levels of DNA-DNA similarity with L. sakei NRIC 1071(T), and were confirmed as L. sakei. The three remaining strains were identified as Lactobacillus curvatus by DNA-DNA similarity, and three other strains were included in the cluster of Lactobacillus plantarum/Lactobacillus pentosus/Lactobacillus paraplantarum and one strain in the cluster of Lactobacillus paracasei on the basis of 16S rRNA gene sequences. Of the 20 L. sakei strains, 19 strains shifted the type of stereoisomers of lactic acid produced from the DL-type to the L-type in the presence of 50 mM sodium acetate. L. curvatus strains and strains included in the cluster of L. plantarum/L. pentosus/L. paraplantarum and in the cluster of L. paracasei did not shift the type of stereoisomers of lactic acid produced. The change of the type of stereoisomers of lactic acid from the DL-type to the L-type in the presence of sodium acetate was concluded to be species-specific for L. sakei and useful for identification of strains in this species.     

Rhizobium selenireducens sp. nov.: A Selenite-Reducing α-Proteobacteria Isolated From a Bioreactor

A Gram-negative, nonpigmented bacterium designated strain B1 was isolated from a laboratory bioreactor that reduced selenate to elemental red selenium (Se(0)). 16S rRNA gene-sequence alignment identified the isolate as a Rhizobium sp. belonging to the Rhizobium clade, which includes R. daejeonense, R. giardinii, R. undicola, R. larrymoorei, R. radiobacter, R. rubi, and R. vitis. R. radiobacter and R. rubi are its closest relatives as indicated by 16S rRNA gene-sequence alignments, which differ from strain B1 by 2.6% and 2.8%, respectively. Within this group, strains that show variances > 0.8% to 2.2% have been classified as different species. The major cellular fatty acids present in the B1 strain were C16:0 (1.8%), C18:0 (3.38%), 18:0 3-OH (1.6%), 18:1 omega7c (86.8%), 19:0 cycloomega8c (1.5%), and summed features 2 (3.8%) and 3 (1.2%). The large amount of 18:1 omega7c present is constant with members of this group of bacteria, but the small amounts of 16:0, 19:0 cycloomega8c, and summed feature 3 shows variance from R. radiobacter and R. rubi. The strain's phenotypic and biochemical characteristics are consistent with its placement in this genus.     

Desulfovibrio aerotolerans sp. nov., an oxygen tolerant sulphate-reducing bacterium isolated from activated sludge

A new mesophilic sulphate-reducing bacterium, designated strain DvO5(T) (T=type strain), was isolated from the outermost sulphate reduction-positive most-probable-number tube (10(-6) dilution) of an activated sludge sample, which had been oxygenated at 100% air saturation for 120 h. The motile, Gram-negative, curved 1 by 2-5 microm and non-spore-forming cells of strain DvO5(T) existed singly or in chains. Strain DvO5(T) grew optimally at 29 degrees C, pH 6.9 and 0.05% (w/v) NaCl in a medium containing lactate, sulphate and yeast extract. Sulphite, thiosulphate and elemental sulphur also served as electron acceptors whereas nitrate, nitrite or ferric iron were not reduced. Lactate, pyruvate, H(2) (with acetate as carbon source), ethanol and glycerol efficiently supported growth as electron donors. Pyruvate and malate were fermented. Strain DvO5(T) reduced oxygen by oxidising endogenous polyglucose at rates ranging from 0.4 to 6.0 nmol O(2)/mg protein min depending on the oxygen concentration, the highest rates being observed at atmospheric oxygen saturation. The G+C content of the DNA was 57.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DvO5(T) was a member of the genus Desulfovibrio with D. magneticus (98.2% 16S rRNA gene sequence similarity) and D. burkinensis (97.5% 16S rRNA gene sequence similarity) being its closest relatives among validly described species. A similar phylogenetic affiliation was obtained by sequence analyses of the genes encoding the alpha and the beta subunit of dissimilatory sulphite reductase (dsrAB) as well as the alpha subunit of adenosine-5'-phosphosulphate reductase (apsA) of strain DvO5(T). On the basis of genotypic and phenotypic characteristics, strain DvO5(T) (DSM 16695(T), JCM 12613(T)) is proposed as the type strain of a new species, Desulfovibrio aerotolerans sp. nov.     

Phylogenetic characterization of the purple sulfur bacterium Thiocapsa sp. BBS by analysis of the 16S rRNA, cbbL, and nifH genes and its description as Thiocapsa bogorovii sp. nov., a new species

Strain BBS, the purple sulfur bacterium assigned initially to the species Thiocapsa roseopersicina, is the best studied representative of this species. However, no molecular phylogenetic analysis has been performed to confirm its systematic position. Based on the results of analysis of the sequences of 16S rRNA, cbbL, and nifH genes, DNA-DNA hybridization with the T. roseopersicina type strain, and comparative analysis of the phenotypic characteristics of various species belonging to the genus Thiocapsa, we suggest that strain BBS should be assigned to a new species of the genus Thiocapsa, Thiocapsa bogorovii sp. nov. Original Russian Text ? T.P. Tourova, O.I. Keppen, O.L. Kovaleva, N.V. Slobodova, I.A. Berg, R.N. Ivanovsky, 2009, published in Mikrobiologiya, 2009, Vol. 78, No. 3, pp. 381–392.     

Saccharopolyspora pathumthaniensis sp. nov., a novel actinomycetes isolated from termite guts (Speculitermes sp.)

Morphological and chemotaxonomic characterization of actinomycete strain S582 isolated from the gut of a termite (Speculitermes sp.) in Pathum Thani Province, Thailand, clearly demonstrated that this strain is a member of the genus Saccharopolyspora. 16S rDNA sequence analysis for the strain supported the assignment of the strain to the genus Saccharopolyspora. The similarity value of sequences between this strain and the closely related species Saccharopolyspora endophytica was 99.5%. The DNA G+C content was 70.2 mol%. DNA-DNA hybridization results (53.3%) and some physiological and biochemical properties indicated that strain S582(T) was distinguished from the phylogenetically closest relatives. Based on these genotypic and phenotypic data, strain S582(T) should be a new species in the genus Saccharopolyspora and the name Saccharopolyspora pathumthaniensis sp. nov. is proposed for the strain. The type strain is S582(T) (=NBRC 104112(T) =BCC 28624(T)).     

Identification and characterization of IS1381, a new insertion sequence in Streptococcus pneumoniae.

A new insertion sequence (IS1381) was identified in the genome of Streptococcus pneumoniae R6 as an 846-bp segment containing 20-bp terminal inverted repeats and flanked by 7-bp direct repeats. The three sequenced copies of this element have two overlapping open reading frame (ORF) genes named orfA and orfB. However, significant variations between individual copies were found, suggesting that inactivating mutations have occurred in an original single ORF. Accordingly, the consensus IS1381 element derived from the comparison of the three available copies should contain a single ORF sufficient to encode a basic protein of 267 amino acids which exhibited high similarity to the putative transposases of ISL2 from Lactobacillus helveticus and of IS702 from the cyanobacterium Calothrix sp. strain PCC 7601. A minimum of five to seven copies were detected by hybridization experiments in the R6 genome. In remarkable contrast with the two previously reported pneumococcal insertion sequences, several copies of IS1381 have been detected in all of the clinical isolates tested so far. Interestingly, Streptococcus oralis NCTC 11427 (type strain), a close relative of pneumococcus, does not contain this element, but its occurrence in the type strain of Streptococcus mitis (NCTC 12261) suggests that this species has exchanged DNA with S. pneumoniae directly or through an intermediate species.     

<Emphasis Type="Italic">Acinetobacter soli</Emphasis> sp. nov., isolated from forest soil

A non-motile and rod shaped bacterium, designated strain B1(T), was isolated from forest soil at Mt. Baekwoon, Republic of Korea. Cells were Gram-negative, catalase-positive, and oxidase-negative. The major fatty acids were 9-octadecenoic acid (C(18:1) omega9c; 42%) and hexadecanoic acid (C(16:0); 25.9%) and summed feature 3 (comprising iso-C(15:0) 2-OH and/or C(16:1) omega7c; 10.0%). The DNA G+C content was 44.1 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain B1(T) formed a lineage within the genus Acinetobacter and was closely related to A. baylyi DSM 14961(T) (98.6% sequence similarity), followed by A. baumannii DSM 30007(T) (97.4%), A. calcoaceticus DSM 30006(T) (97.0%) and 3 genomic species (96.8 approximately 7.6%). Phenotypic characteristics, gyrB gene sequence analysis and DNA-DNA relatedness data distinguished strain B1(T) from type strains of A. baylyi, A. baumannii, and A. calcoaceticus. On the basis of the evidence presented in this study, strain B1(T) represents a novel species of the genus Acinetobacter, for which the name Acinetobacter soli sp. nov. is proposed. The type strain is B1(T) (= KCTC 22184(T)= JCM 15062(T)).     

Candida alocasiicola sp. nov., Candida hainanensis sp. nov., Candida heveicola sp. nov. and Candida musiphila sp. nov., novel anamorphic, ascomycetous yeast species isolated from plants

In a taxonomic study on the ascomycetous yeasts isolated from plant materials collected in tropical forests in Yunnan and Hainan Provinces, southern China, four strains isolated from tree sap (YJ2E(T)) and flowers (YF9E(T), YWZH3C(T) and YYF2A(T)) were revealed to represent four undescribed yeast species. Molecular phylogenetic analysis based on the large subunit (26S) rRNA gene D1/D2 domain sequences showed that strain YJ2E(T) was located in a clade together with Candida haemulonii and C. pseudohaemulonii. Strain YF9E(T) was most closely related to C. azyma and strain YWZH3C(T) to C. sorbophila and C. spandovensis. Strain YYF2A(T) was clustered in a clade containing small-spored Metschnikowia species and related anamorphic Candida species. The new strains differed from their closely related described species by more than 10% mismatches in the D1/D2 domain. No sexual states were observed for the four strains on various sporulation media. The new species are therefore assigned to the genus Candida and described as Candida alocasiicola sp. nov. (type strain, YF9E(T) = AS 2.3484(T) = CBS 10702(T)), Candida hainanensis sp. nov. (type strain, YYF2A(T) = AS 2.3478(T) = CBS 10696(T)), Candida heveicola sp. nov. (type strain, YJ2E(T) = AS 2.3483(T) = CBS 10701(T)) and Candida musiphila sp. nov. (type strain, YWZH3C(T) = AS 2.3479(T) = CBS 10697(T)).
