TL;DR: A new genus and species of anaerobic ammonium oxidizing planctomycetes, discovered in a wastewater treatment plant treating landfill leachate in Pitsea, UK, are described, making this genus the most widespread of all anammox bacteria described so far.

TL;DR: Although a low risk seems to be associated with the use of enterococci in long-established artisanal cheeses, screening of virulence traits and their cross-synergies must be performed, particularly for commercial starters, probiotic strains and products to be used by high risk population groups.

TL;DR: A sequential use of the three enzymes is proposed to simplify LAB wine identification, first MseI, then BfaI and finally, if necessary, AluI digestion, able to discriminate 32 of the 36 LAB reference species tested and allowed the identification of 342 isolates from musts and wines.

TL;DR: This is the first in vitro study about the antimicrobial characteristics of the Lactobacillus population of kefir and it revealed that it was closely related to keFiran, a polysaccharide with antitumoral properties.

TL;DR: Assignment of this new taxon represents the fourth example in the literature of a non-rhizobial genus of bacteria capable of forming a bonafide dinitrogen-fixing root-nodule symbiosis with legume plants, which is named Devosia neptuniae sp.

TL;DR: An overview of various molecular techniques and their application for the detection and identification of bifidobacteria and lactobacilli in the gastrointestinal (GI) tract is presented.

TL;DR: Five strains of methanogenic archaea were isolated from permanently and periodically cold terrestrial habitats and all of them have their growth optima in the range of moderate temperatures, so they can be regarded as psychrotolerant organisms.

TL;DR: In this article, an unusual bile-resistant pigment-producing strictly anaerobic gram-negative rod was isolated from inflamed and non-inflamed tissue samples, which was classified as Alistipes putredinis comb.

TL;DR: Phenorypic and phylogenetic studies were performed on four isolates of an unidentified gram-negative, microaerotolerant, non-spore-forming, rod-shaped bacterium isolated from the feces of children, and it was proposed that the unknown fecal bacterium be classified in the genus Cetobacterium.

TL;DR: Rep-PCR fingerprinting using the BOXA1R primer can be considered as a promising genotypic tool for the identification of a wide range of bifidobacteria at the species, subspecies and potentially up to the strain level.

TL;DR: A new species, Sinorhizobium americanus, is described and the type strain is CFNEI 156 from Acacia acatlensis, and nolR gene hybridization patterns were found useful to identify sinorHizobia and characterize species.

TL;DR: Cultures of a new biogroup of Yersinia ruckeri, the causal agent of enteric redmouth (ERM), were recovered in England from diseased rainbow trout, which had been previously vaccinated with a commercial ERM vaccine.

TL;DR: In this paper, an extension of a previous small-scale test to assess the use of 16S-23S rDNA internal transcribed spacer (ITS) sequences for rapid grouping of bradyrhizobia was presented.

TL;DR: In this paper, the α-subdomain of the substrate-binding domain of DnaK was used for phylogenetic analysis of rhizobia and related non-symbiotic alpha-Proteobacteria.

TL;DR: Based upon results obtained by morphological, biochemical, chemotaxonomic, and molecular methods, strain W3-B1 was clearly distinguishable from other Chryseobacterium species and a novel species of family Flavobacteriaceae is proposed.

TL;DR: In this article, two staphylococcal strains, RP29 T and RP33, were isolated from the main microflora of a surface-ripened Swiss mountain cheese made from raw milk.

TL;DR: In this article, the authors used fluorescent in situ hybridization (FISH) combined with flow cytometry to identify cells belonging to Bacteroides distasonis, B. vulgatus and B. putredinis.

TL;DR: The prevalence of the bacterium was significantly higher in European sea bass than in gilthead sea bream, and was closely related to the season in both fish species, occurring almost exclusively on warm months (June to November).

TL;DR: 70 strains of Aspergillus ochraceus mainly isolated from Brazilian coffee related sources were investigated for genetic relatedness using automated laser fluorescence analysis of AFLP fragments, revealing a very close relationship among most of the strains.

TL;DR: Comparison of genomic and metabolic properties of the actinomycetes FH 1894T, ST 101170T, and FH 1893T, producing novel glycopeptide antibiotics and a polyenic compound indicated that they represent new species for which the names Amycolatopsis balhimycina and Amycol atopsis vancoresmycina are proposed.

TL;DR: It is concluded that Lupinus is a promiscuous host legume that is nodulated by rhizobia with very different chromosomal genotypes, which could even belong to several species of Bradyrhizobium.

TL;DR: The size and sequence of ISR appears to be a unique marker for streptococci of various species and subspecies and could be used for bacterial identification.

TL;DR: Physiological and chemotaxonomic differences between the new strains and strains of the genus Plesiocystis justify the proposal of a new genus of marine myxobacteria, Enhygromyxa salina gen. nov.

TL;DR: A taxonomic study was carried out on eight strains of Saccharomyces boulardii and the results of the study strongly indicate a close relatedness of S. boulardi to S. cerevisiae as discussed by the authors.

TL;DR: There were high similarities in the community composition between different water samples and between larvae samples collected at different time periods, indicating a high stability in the bacterial communities.

TL;DR: In this article, the PFGE macrorestriction patterns of persistent and sporadic Listeria monocytogenes strains from different processing plants were compared and the strains were further studied by amplified fragment length polymorphism (AFLP), being a characterisation method giving more whole genome based information.

TL;DR: Strains of the unidentified bacterium used carbohydrate as fermentable substrates, producing acetic acid and lactic acid as the major products of glucose metabolism and it is proposed that the unknown bacterium, be classified as Clostridium bolteae sp.

TL;DR: It is proposed that the isolates which formed a tight AFLP group in a former study represent a new Vibrio species i.e. V. tasmaniensis (LMG 20012T; EMBL under the accession numbers AJ316192; mol% G+C of DNA of the type strain is 44.7).

TL;DR: Comparison of the 33Pi, [3H]-acetate and [ 3H]-glucose uptake by activated sludge after different fixation and incubation procedures showed that a part of the observed 33Pi uptake may have been caused by a combination of a biological and chemical or biologically induced chemical P adsorption.

TL;DR: This report provides the first description of additional members of the order Chlamydiales infecting the koala, including multiple novel chlamydials present in a single sample.
