Isolation And Characterization

Three novel strains of methylotrophic methanogens were isolated from Skan Bay, Alaska, by using anaerobic cultivation techniques. The water was 65 m deep at the sampling site. Strains AK-4 (=OCM 774), AK-5T (=OCM 775T=DSM 17273T) and AK-9 (=OCM 793) were isolated from the sulfate-reducing zone of the sediments. Each of the strains was a non-motile coccus and occurred singly. Cells grew with trimethylamine as a catabolic substrate and strain AK-4 could also catabolize methanol. Yeast extract and trypticase peptones were not required for growth, but their addition to the culture medium slightly stimulated growth. Each of the strains grew at temperatures of 5–28 °C; they were slight halophiles and grew fastest in the neutral pH range. Analysis of the 16S rRNA gene sequences indicated that strain AK-4 was most closely related to Methanosarcina baltica. DNA–DNA hybridization studies showed 88 % relatedness, suggesting that strain AK-4 represents a novel strain within this species. Strains AK-5T and AK-9 had identical 16S rRNA gene sequences that were most closely related to the sequence of Methanococcoides burtonii (99·8 % sequence similarity). DNA–DNA hybridization studies showed that strains AK-5T and AK-9 are members of the same species (88 % relatedness value), but strain AK-5T had a DNA–DNA relatedness value of only 55 % to Methanococcoides burtonii. This indicates that strains AK-5T and AK-9 should be considered as members of a novel species in the genus Methanococcoides. We propose the name Methanococcoides alaskense sp. nov., with strain AK-5T (=OCM 775T=DSM 17273T) as the type strain.

© 2017 IUMS. A novel anaerobic pectinolytic bacterium (strain 14T) was isolated from human faeces. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 14T belonged to the family Ruminococcaceae, but was located separately from known clostridial clusters within the taxon. The closest cultured relative of strain 14T was Acetivibrio cellulolyticus (89.7% sequence similarity). Strain 14T shared ~99% sequence similarity with cloned 16S rRNA gene sequences from uncultured bacteria derived from the human gut. Cells were Gram-stain-positive, non-motile cocci approximately 0.6μm in diameter. Strain 14T fermented pectins from citrus peel, apple, and kiwifruit as well as carbohydrates that are constituents of pectins and hemicellulose, such as galacturonic acid, xylose, and arabinose. TEM images of strain 14T, cultured in association with plant tissues, suggested extracellular fibrolytic activity associated with the bacterial cells, forming zones of degradation in the pectin-rich regions of middle lamella. Phylogenetic and phenotypic analysis supported the differentiation of strain 14T as a novel genus in the family Ruminococcaceae. The name Monoglobus pectinilyticus gen. nov., sp. nov. is proposed; the type strain is 14T (JCM 31914T=DSM 104782T).

The 16S Rrna Gene

A beige-pigmented bacterial strain (JM-310T), isolated from the healthy internal root tissue of 4-week-old cotton (Gossypium hirsutum, cultivar ‘DES-119’) in Tallassee (Macon county), Alabama, USA, was studied taxonomically. The isolate produced small rod-shaped cells, which showed a Gram-negative staining behaviour. A comparison of the 16S rRNA gene sequence of the isolate revealed 99.2, 98.8, 98.7, 98.7, 98.1 and 97.6 % similarity to the 16S rRNA gene sequences of the type strains of Variovorax paradoxus, Variovorax boronicumulans, Variovorax ginsengisoli, Variovorax soli, Variovorax defluvii and Variovorax dokdonensis, respectively. In phylogenetic trees based on 16S rRNA gene sequences, strain JM-301T was placed within the monophyletic cluster of Variovorax species. The fatty acid profile of strain JM-310T consisted mainly of the major fatty acids C16 : 0, C10 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH/C16 : 1ω7c/t). The quinone system of strain JM-310T contained predominantly ubiquinone Q-8 and lesser amounts of Q-7 and Q-9. The major polyamine was putrescine and the diagnostic polyamine 2-hydroxyputrescine was detected as well. The polar lipid profile consisted of the major lipids phosphatidylethanolamine, phosphatidylglycerol, diphospatidylglycerol and several unidentified lipids. DNA–DNA hybridization experiments with V. paradoxus LMG 1797T, V. boronicumulans 1.22T, V. soli KACC 11579T and V. ginsengisoli 3165T gave levels of relatedness of < 70 %. These DNA–DNA hybridization results in addition to differential biochemical properties indicate clearly that strain JM-310T is a member of a novel species, for which the name Variovorax gossypii sp. nov. is proposed. The type strain is JM-310T ( = LMG 28869T = CIP 110912T = CCM 8614T).

Thirteen strains of a novel spore-forming, Gram-positive, mesophilic heterotrophic bacterium were isolated from spacecraft surfaces (Mars Odyssey Orbiter) and assembly-facility surfaces at the Jet Propulsion Laboratory in California and the Kennedy Space Center in Florida. Phylogenetic analysis of 16S rRNA gene sequences has placed these novel isolates within the genus Bacillus, the greatest sequence similarity (99.9 %) being found with Bacillus pumilus. However, these isolates share a mere 91.2 % gyrB sequence similarity with Bacillus pumilus, rendering their 16S rRNA gene-derived relatedness suspect. Furthermore, DNA–DNA hybridization showed only 54–66 % DNA relatedness between the novel isolates and strains of B. pumilus. rep-PCR fingerprinting and previously reported matrix-assisted laser desorption/ionization time-of-flight mass spectrometry protein profiling clearly distinguished these isolates from B. pumilus. Phenotypic analyses also showed some differentiation between the two genotypic groups, although the fatty acid compositions were almost identical. The polyphasic taxonomic studies revealed distinct clustering of the tested strains into two distinct species. On the basis of phenotypic characteristics and the results of phylogenetic analyses of 16S rRNA and gyrB gene sequences, repetitive element primer-PCR fingerprinting and DNA–DNA hybridization, the 13 isolates represent a novel species of the genus Bacillus, for which the name Bacillus safensis sp. nov. is proposed. The type strain is FO-36bT (=ATCC BAA-1126T=NBRC 100820T).

A water sample from the North Sea was used to isolate the abundant heterotrophic bacteria that are able to grow on complex marine media. Isolation was by serial dilution and spread plating. Phylogenetic analysis of nearly complete 16S rRNA gene sequences revealed that one of the strains, HEL-45T, had 97·4 % sequence similarity to Sulfitobacter mediterraneus and 96·5 % sequence similarity to Staleya guttiformis. Strain HEL-45T is a Gram-negative, non-motile rod and obligate aerobe and requires sodium and 1–7 % sea salts for growth. It contains storage granules and does not produce bacteriochlorophyll. Optimal growth temperatures are 25–30 °C. The DNA base composition (G+C content) is 60·1 mol%. Strain HEL-45T has Q10 as the dominant respiratory quinone. The major polar lipids are phosphatidyl glycerol, diphosphatidyl glycerol, phosphatidyl choline, phosphatidyl ethanolamine and an aminolipid. The fatty acids comprise 18 : 1ω7c, 18 : 0, 16 : 1ω7c, 16 : 0, 3-OH 10 : 0, 3-OH 12 : 1 (or 3-oxo 12 : 0) and traces of an 18 : 2 fatty acid. Among the hydroxylated fatty acids only 3-OH 12 : 1 (or 3-oxo 12 : 0) appears to be amide linked, whereas 3-OH 10 : 0 appears to be ester linked. The minor fatty acid components (between 1 and 7 %) allow three subgroups to be distinguished in the Sulfitobacter/Staleya clade, placing HEL-45T into a separate lineage characterized by the presence of 3-OH 12 : 1 (or 3-oxo 12 : 0) and both ester- and amide-linked 16 : 1ω7c phospholipids. HEL-45T produces indole and derivatives thereof, several cyclic dipeptides and thryptanthrin. Phylogenetic analysis of 16S rRNA gene sequences and chemotaxonomic data support the description of a new genus and species, to include Oceanibulbus indolifex gen. nov., sp. nov., with the type strain HEL-45T (=DSM 14862T=NCIMB 13983T).

ABSTRACT High-throughput cultivation was combined with rapid and group-specific phylogenetic fingerprinting in order to recover representatives of three freshwater bacterioplankton communities. A total of 570 bacterial cultures were obtained by employing the most probable number and MicroDrop techniques. The majority of the cultured bacteria were closely related to previously uncultured bacteria and grouped with the α-Proteobacteria, β-Proteobacteria, Actinobacteria, Firmicutes, or Flavobacteria-Cytophaga lineage. Correspondingly, the natural bacterioplankton community was analyzed by high-resolution phylogenetic fingerprinting of these five bacterial lineages. 16S rRNA gene fragments were generated for each lineage and subsequently separated by denaturing gradient gel electrophoresis. By the combination of five group-specific PCR protocols, the total number of 16S rRNA gene fingerprints generated from the natural communities was increased sixfold compared to conventional (eubacterial) fingerprinting. Four of the environmental α-Proteobacteria 16S rRNA gene sequences obtained from the natural community were found to be identical to those of bacterial isolates. One of these phylotypes was detected in 14 different cultures and hence represented the most frequently cultured bacterium. Three of these 14 strains were characterized in detail. Their complete 16S rRNA gene sequences showed only 93% similarity to that of Sandaracinobacter sibiricus, the closest relative described so far. The novel phylotype of bacterium is a strict aerobe capable of using numerous organic carbon substrates and contains bacteriochlorophyll a bound to two different photosynthetic light-harvesting complexes. Dot blot hybridization revealed that the strains occur in lakes of different trophic status and constitute up to 2% of the microbial community.

Three isolates originating from Spanish-style green-olive fermentations in a manufacturing company in the province of Seville, Spain, were taxonomically characterized by a polyphasic approach. This included a phylogenetic analysis based on 16S rRNA gene sequences and multi-locus sequence analysis (MLSA) based on pyrH, recA, rpoA, gyrB and mreB genes. The isolates shared 98.0 % 16S rRNA gene sequence similarity with Vibrio xiamenensis G21T. Phylogenetic analysis based on 16S rRNA gene sequences using the neighbour-joining and maximum-likelihood methods showed that the isolates fell within the genus Vibrio and formed an independent branch close to V. xiamenensis G21T. The maximum-parsimony method grouped the isolates to V. xiamenensis G21T but forming two clearly separated branches. Phylogenetic trees based on individual pyrH, recA, rpoA, gyrB and mreB gene sequences revealed that strain IGJ1.11T formed a clade alone or with V. xiamenensis G21T. Sequence similarities of the pyrH, recA, rpoA, gyrB and mreB genes between strain IGJ1.11T and V. xiamenensis G21T were 86.7, 85.7, 97.3, 87.6 and 84.8 %, respectively. MLSA of concatenated sequences showed that strain IGJ1.11T and V. xiamenensis G21T are two clearly separated species that form a clade, which we named Clade Xiamenensis, that presented 89.7 % concatenated gene sequence similarity, i.e. less than 92 %. The major cellular fatty acids (>5 %) of strain IGJ1.11T were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). Enzymic activity profiles, sugar fermentation patterns and DNA G+C content (52.9 mol%) differentiated the novel strains from the closest related members of the genus Vibrio. The name Vibrio olivae sp. nov. is proposed for the novel species. The type strain is IGJ1.11T ( = CECT 8064T = DSM 25438T).

ABSTRACT Novel thermophilic crenarchaea have been observed in Fe(III) oxide microbial mats of Yellowstone National Park (YNP); however, no definitive work has identified specific microorganisms responsible for the oxidation of Fe(II). The objectives of the current study were to isolate and characterize an Fe(II)-oxidizing member of the Sulfolobales observed in previous 16S rRNA gene surveys and to determine the abundance and distribution of close relatives of this organism in acidic geothermal springs containing high concentrations of dissolved Fe(II). Here we report the isolation and characterization of the novel, Fe(II)-oxidizing, thermophilic, acidophilic organism Metallosphaera sp. strain MK1 obtained from a well-characterized acid-sulfate-chloride geothermal spring in Norris Geyser Basin, YNP. Full-length 16S rRNA gene sequence analysis revealed that strain MK1 exhibits only 94.9 to 96.1% sequence similarity to other known Metallosphaera spp. and less than 89.1% similarity to known Sulfolobus spp. Strain MK1 is a facultative chemolithoautotroph with an optimum pH range of 2.0 to 3.0 and an optimum temperature range of 65 to 75°C. Strain MK1 grows optimally on pyrite or Fe(II) sorbed onto ferrihydrite, exhibiting doubling times between 10 and 11 h under aerobic conditions (65°C). The distribution and relative abundance of MK1-like 16S rRNA gene sequences in 14 acidic geothermal springs containing Fe(III) oxide microbial mats were evaluated. Highly related MK1-like 16S rRNA gene sequences (>99% sequence similarity) were consistently observed in Fe(III) oxide mats at temperatures ranging from 55 to 80°C. Quantitative PCR using Metallosphaera-specific primers confirmed that organisms highly similar to strain MK1 comprised up to 40% of the total archaeal community at selected sites. The broad distribution of highly related MK1-like 16S rRNA gene sequences in acidic Fe(III) oxide microbial mats is consistent with the observed characteristics and growth optima of Metallosphaera-like strain MK1 and emphasizes the importance of this newly described taxon in Fe(II) chemolithotrophy in acidic high-temperature environments of YNP.

An analysis of 16S rRNA gene sequences from archived clinical reference specimens identified a novel species of the genus Psychrobacter, of which four strains have been independently isolated from human blood. On the basis of 16S rRNA gene sequence similarity, the closest relatives with validly published names were Psychrobacter arenosus R7T (98.7 %), P. pulmonis CECT 5989T (97.7 %), P. faecalis Iso-46T (97.6 %) and P. lutiphocae IMMIB L-1110T (97.2 %). Maximum-likelihood phylogenetic analysis of 16S rRNA gene sequences showed that the isolates belonged to the genus Psychrobacter and were members of a cluster associated with Psychrobacter sp. PRwf-1, isolated from a silk snapper fish. DNA–DNA relatedness and partial 23S rRNA gene sequences also supported the finding that the isolates belonged to a species distinct from its closest phylogenetic neighbours. The predominant cellular fatty acids were C18 : 1ω9c, C16 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), summed feature 5 (C18 : 2ω6,9c and/or anteiso-C18 : 0) and C18 : 0. Biochemical and morphological analysis further supported the assignment of the four isolates to a novel species. The name Psychrobacter sanguinis sp. nov. is proposed. The type strain is 13983T ( = DSM 23635T = CCUG 59771T).

A novel actinobacterium, designated strain NEAU-QY2T, was isolated from the leaves of Sonchus oleraceus L. specimen, collected from Wuchang, Heilongjiang Province, China. A polyphasic study was carried out to establish the taxonomic position of this strain. The organism formed single spores with rough surfaces on substrate mycelia. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-QY2T belonged to the genus Plantactinospora and formed a monophyletic clade with its closest related strains Plantactinospora endophytica YIM 68255T (99.2 % 16S rRNA gene sequence similarity), Plantactinospora veratri NEAU-FHS4T (98.8 %) and Plantactinospora mayteni YIM 61359T (98.7 %), an association that was supported by a bootstrap value of 90 % in the neighbour-joining tree and also recovered with the maximum-likelihood algorithm. However, DNA–DNA hybridization values between strain NEAU-QY2T and the three closely related strains were below 70 %. With reference to phenotypic characteristics, phylogenetic data and DNA–DNA hybridization results, strain NEAU-QY2T was distinguished from closely related strains and is classified as representing a novel species of the genus Plantactinospora, for which the name Plantactinospora sonchi sp. nov. is proposed. The type strain is NEAU-QY2T ( = CGMCC 4.7216T = JCM 30345T).
