In addition, the sequence of the dsrAB gene homologs of the sulfite reducer Desulfitobacterium dehalogenans was determined. In contrast to previous reports, comparative analysis of all available DsrAB sequences produced a tree topology partially inconsistent with the corresponding 16S rRNA phylogeny. For example, the DsrAB sequences of -several Desulfotomaculum species (low G؉C gram-positive division) and two members of the genus Thermode sulfobacterium (a separate bacterial division) were monophyletic with ␦-proteobacterial DsrAB sequences. -

(Pelobacter) and Methanococcoides Are Responsible for Choline-Dependent Methanogenesis in a Coastal Saltmarsh Sediment
The ISME Journal https://doi.org/10.1038/s41396-018-0269-8 ARTICLE Deltaproteobacteria (Pelobacter) and Methanococcoides are responsible for choline-dependent methanogenesis in a coastal saltmarsh sediment 1 1 1 2 3 1 Eleanor Jameson ● Jason Stephenson ● Helen Jones ● Andrew Millard ● Anne-Kristin Kaster ● Kevin J. Purdy ● 4 5 1 Ruth Airs ● J. Colin Murrell ● Yin Chen Received: 22 January 2018 / Revised: 11 June 2018 / Accepted: 26 July 2018 © The Author(s) 2018. This article is published with open access Abstract Coastal saltmarsh sediments represent an important source of natural methane emissions, much of which originates from quaternary and methylated amines, such as choline and trimethylamine. In this study, we combine DNA stable isotope 13 probing with high throughput sequencing of 16S rRNA genes and C2-choline enriched metagenomes, followed by metagenome data assembly, to identify the key microbes responsible for methanogenesis from choline. Microcosm 13 incubation with C2-choline leads to the formation of trimethylamine and subsequent methane production, suggesting that 1234567890();,: 1234567890();,: choline-dependent methanogenesis is a two-step process involving trimethylamine as the key intermediate. Amplicon sequencing analysis identifies Deltaproteobacteria of the genera Pelobacter as the major choline utilizers. Methanogenic Archaea of the genera Methanococcoides become enriched in choline-amended microcosms, indicating their role in methane formation from trimethylamine. The binning of metagenomic DNA results in the identification of bins classified as Pelobacter and Methanococcoides. Analyses of these bins reveal that Pelobacter have the genetic potential to degrade choline to trimethylamine using the choline-trimethylamine lyase pathway, whereas Methanococcoides are capable of methanogenesis using the pyrrolysine-containing trimethylamine methyltransferase pathway. -
Distribution of Bacterial Populations in a Stratified Fjord

RAMSING,1* HENRIK FOSSING,1 TIMOTHY G. FERDELMAN,1 2 1 FINN ANDERSEN, AND BO THAMDRUP Max Planck Institute for Marine Microbiology, Bremen, Germany,1 and Nordjyllands Amt, Aalborg, Denmark2 Received 28 August 1995/Accepted 29 January 1996 The vertical distribution of major and intermediate electron acceptors and donors was measured in a shallow stratified fjord. Peaks of zero valence sulfur, Mn(IV), and Fe(III) were observed in the chemocline separating oxic surface waters from sulfidic and anoxic bottom waters. The vertical fluxes of electron acceptors and donors (principally O2 and H2S) balanced within 5%; however, the zones of oxygen reduction and sulfide oxidation were clearly separated. The pathway of electron transfer between O2 and H2S was not apparent from the distribution of sulfur, nitrogen, or metal compounds investigated. The chemical zonation was related to bacterial populations as detected by ethidium bromide (EtBr) staining and by in situ hybridization with fluorescent oligonucleotide probes of increasing specificity. About half of all EtBr-stained cells were detectable with a general oligonucleotide probe for all eubacteria when digital image analysis algorithms were used to improve sensitivity. Both EtBr staining and hybridization indicated a surprisingly uniform distribution of bacteria throughout the water column. However, the average cell size and staining intensity as well as the abundance of different morphotypes changed markedly within the chemocline. -

We tested ethanol as substrate in bioreactors designed for biological sulfate removal from mine water containing up to 9 g L−1 sulfate, using granular sludge from an industrial waste water treatment plant as inoculum. The pH, redox potential, and sulfate and sulfide concentrations were measured twice a week over a maximum of 171 days. The microbial communities in the bioreactors were characterized by qPCR and high throughput amplicon sequencing. The pH in the bioreactors fluctuated between 5.0 and 7.7 with the highest amount of up to 50% sulfate removed measured around pH 6. Dissimilatory sulfate reducing bacteria (SRB) constituted only between 1% and 15% of the bacterial communities. Predicted bacterial metagenomes indicated a high prevalence of assimilatory sulfate reduction proceeding to formation of L-cystein and acetate, assimilatory and dissimilatory nitrate reduction, denitrification, and oxidation of ethanol to acetaldehyde with further conversion to ethanolamine, but not to acetate. Despite efforts to maintain optimal conditions for biological sulfate reduction in the bioreactors, only a small part of the microorganisms were SRB. -

Bacterial Involvements in Ulcerative Colitis: Molecular and Microbiological Studies
BACTERIAL INVOLVEMENTS IN ULCERATIVE COLITIS: MOLECULAR AND MICROBIOLOGICAL STUDIES Samia Alkhalil A thesis submitted in partial fulfilment of the requirements for the award of the degree of Doctor of Philosophy of the University of Portsmouth Institute of Biomedical and biomolecular Sciences School of Pharmacy and Biomedical Sciences October 2017 AUTHORS’ DECLARATION I declare that whilst registered as a candidate for the degree of Doctor of Philosophy at University of Portsmouth, I have not been registered as a candidate for any other research award. The results and conclusions embodied in this thesis are the work of the named candidate and have not been submitted for any other academic award. Samia Alkhalil I ABSTRACT Inflammatory bowel disease (IBD) is a series of disorders characterised by chronic intestinal inflammation, with the principal examples being Crohn’s Disease (CD) and ulcerative colitis (UC). A paradigm of these disorders is that the composition of the colon microbiota changes, with increases in bacterial numbers and a reduction in diversity, particularly within the Firmicutes. Sulfate reducing bacteria (SRB) are believed to be involved in the etiology of these disorders, because they produce hydrogen sulfide which may be a causative agent of epithelial inflammation, although little supportive evidence exists for this possibility. The purpose of this study was (1) to detect and compare the relative levels of gut bacterial populations among patients suffering from ulcerative colitis and healthy individuals using PCR-DGGE, sequence analysis and biochip technology; (2) develop a rapid detection method for SRBs and (3) determine the susceptibility of Desulfovibrio indonesiensis in biofilms to Manuka honey with and without antibiotic treatment. -
