Based on characterization using a polyphasic approach, the three strains showed highly similar phenotypic, physiological and genetic characteristics. All of the strains harboured the nitrogenase gene nifH, but nitrogen-fixing activities could not be detected in nitrogen-free culture media. The three strains shared 99.6–99.7 % 16S rRNA gene sequence similarity and showed 89–100 % DNA–DNA relatedness, suggesting that they represent a single genomic species. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains d8-1T, d8-2 and IMCC1716 formed a monophyletic branch in the periphery of the evolutionary radiation occupied by the genus Azonexus. -

It has for some years been clear that most microorganisms in biological wastewater systems cannot be reliably identified and quantified by conventional microscopy or by traditional culture-dependent methods such as plate counts. Therefore, molecular FISH Handbook biological methods are vital and must be introduced instead of, or in addition to, conventional methods. At present, FISH is the most widely used and best tested of these methods. -

Given a draft genome, one first task is to 3 determine its phylogenetic context, that is, to place it relative to the set of related reference 4 genomes. We provide a new interactive graphical tool that addresses this task using Mash 5 sketches to compare against all bacterial and archaeal representative genomes in the 6 GTDB taxonomy, all within the framework of SplitsTree5. The phylogenetic context of the 7 query sequences is then displayed as a phylogenetic outline, a new type of phylogenetic 8 network that is more general that a phylogenetic tree, but significantly less complex than 9 other types of phylogenetic networks. We propose to use such networks, rather than trees, 10 to represent phylogenetic context, because they can express uncertainty in the placement 11 of taxa, whereas a tree must always commit to a specific branching pattern. -

Repeated Anaerobic Microbial Redox Cycling of Ironᰔ† Aaron J. Coby,1‡ Flynn Picardal,2 Evgenya Shelobolina,1 Huifang Xu,1 and Eric E. Roden1* Department of Geoscience, University of Wisconsin, Madison, Wisconsin 53706,1 and School of Public and Environmental Affairs, Indiana University, Bloomington, Indiana 474052 Received 7 February 2011/Accepted 28 June 2011 Some nitrate- and Fe(III)-reducing microorganisms are capable of oxidizing Fe(II) with nitrate as the electron acceptor. This enzymatic pathway may facilitate the development of anaerobic microbial communities that take advantage of the energy available during Fe-N redox oscillations. We examined this phenomenon in synthetic Fe(III) oxide (nanocrystalline goethite) suspensions inoculated with microflora from freshwater river floodplain sediments. Nitrate and acetate were added at alternate intervals in order to induce repeated cycles of microbial Fe(III) reduction and nitrate-dependent Fe(II) oxidation. Addition of nitrate to reduced, acetate- depleted suspensions resulted in rapid Fe(II) oxidation and accumulation of ammonium. High-resolution transmission electron microscopic analysis of material from Fe redox cycling reactors showed amorphous coatings on the goethite nanocrystals that were not observed in reactors operated under strictly nitrate- or Fe(III)-reducing conditions. Microbial communities associated with N and Fe redox metabolism were assessed using a combination of most-probable-number enumerations and 16S rRNA gene analysis. The nitrate- reducing and Fe(III)-reducing cultures were dominated by denitrifying Betaproteobacteria (e.g., Dechloromonas) and Fe(III)-reducing Deltaproteobacteria (Geobacter), respectively; these same taxa were dominant in the Fe cycling cultures. -
