The type strain Z was isolated from surface sediments of Tar Pit Lake in the La Brea Tar Pits in Los Angeles, California. M. labreanum is of phylogenetic interest because at the time the sequencing project began only one genome had previously been sequenced from the order Methanomicrobiales. We report here the complete genome sequence of M. labreanum type strain Z and its annotation. This is part of a 2006 Joint Genome Institute Community Sequencing Program project to sequence genomes of diverse Archaea. Introduction Methanocorpusculum labreanum is a methanogen the Methanosarcinales are capable of using various belonging to the order Methanomicrobiales within methyl compounds as substrates for methanoge- the archaeal phylum Euryarchaeota. Strain Z is the nesis including acetate, methylamines, and me- type strain of this species. It was isolated from thanol, but Methanomicrobiales are restricted to surface sediments of Tar Pit Lake at the La Brea the same substrates as the Class I methanogens Tar Pits in Los Angeles [1]. -

The interactions of microbial communities in these environments are highly complex and still poorly understood. This work aimed to assess publicly available metagenomes from oil reservoirs and implement a robust pipeline of genome-resolved metagenomics to decipher metabolic and taxonomic profiles of petroleum reservoirs worldwide. Analysis of 301.2 Gb of metagenomic information derived from heavily flooded petroleum reservoirs in China and Alaska to non-flooded petroleum reservoirs in Brazil enabled us to reconstruct 148 metagenome-assembled genomes (MAGs) of high and medium quality. At the phylum level, 74% of MAGs belonged to bacteria and 26% to archaea. The profiles of these MAGs were related to the physicochemical parameters and recovery management applied. -

Baldwin * Chemical and Biological Engineering, University of British Columbia, 2360 East Mall, Vancouver, BC V6T 1Z3, Canada; [email protected] * Correspondence: [email protected]; Tel.: +1-604-822-1973 Received: 2 January 2018; Accepted: 17 February 2018; Published: 23 February 2018 Abstract: Biochemical reactors (BCRs) based on the stimulation of sulphate-reducing microorganisms (SRM) are emerging semi-passive remediation technologies for treatment of mine-influenced water. Their successful removal of metals and sulphate has been proven at the pilot-scale, but little is known about the types of SRM that grow in these systems and whether they are diverse or restricted to particular phylogenetic or taxonomic groups. A phylogenetic study of four established pilot-scale BCRs on three different mine sites compared the diversity of SRM growing in them. The mine sites were geographically distant from each other, nevertheless the BCRs selected for similar SRM types. Clostridia SRM related to Desulfosporosinus spp. known to be tolerant to high concentrations of copper were members of the core microbial community. Members of the SRM family Desulfobacteraceae were dominant, particularly those related to Desulfatirhabdium butyrativorans. Methanogens were dominant archaea and possibly were present at higher relative abundances than SRM in some BCRs. Both hydrogenotrophic and acetoclastic types were present. There were no strong negative or positive co-occurrence correlations of methanogen and SRM taxa. Knowing which SRM inhabit successfully operating BCRs allows practitioners to target these phylogenetic groups when selecting inoculum for future operations. -

Hence, the present study tried to identify microbial community in non-water flooding Zeilaei (ZZ) oil reservoir. Materials and methods: In this study, for the first time, non-water flooded high temperature Zeilaei oilfield was analyzed for its microbial community based on next generation sequencing of 16S rRNA genes. Results: The results obtained from this study indicated that the most abundant bacterial community belonged to phylum of Firmicutes (Bacilli ) and Thermotoga, while other phyla (Proteobacteria , Actinobacteria and Synergistetes ) were much less abundant. Bacillus subtilis , B. licheniformis , Petrotoga mobilis , P. miotherma, Fervidobacterium pennivorans , and Thermotoga subterranea were observed with high frequency. In addition, the most abundant archaea were Methanothermobacter thermautotrophicus . Discussion and conclusion: Although there are many reports on the microbial community of oil filed reservoirs, this is the first report of large quantities of Bacillus spp. -
Developing a Genetic Manipulation System for the Antarctic Archaeon, Halorubrum Lacusprofundi: Investigating Acetamidase Gene Function
www.nature.com/scientificreports OPEN Developing a genetic manipulation system for the Antarctic archaeon, Halorubrum lacusprofundi: Received: 27 May 2016 Accepted: 16 September 2016 investigating acetamidase gene Published: 06 October 2016 function Y. Liao1, T. J. Williams1, J. C. Walsh2,3, M. Ji1, A. Poljak4, P. M. G. Curmi2, I. G. Duggin3 & R. Cavicchioli1 No systems have been reported for genetic manipulation of cold-adapted Archaea. Halorubrum lacusprofundi is an important member of Deep Lake, Antarctica (~10% of the population), and is amendable to laboratory cultivation. Here we report the development of a shuttle-vector and targeted gene-knockout system for this species. To investigate the function of acetamidase/formamidase genes, a class of genes not experimentally studied in Archaea, the acetamidase gene, amd3, was disrupted. The wild-type grew on acetamide as a sole source of carbon and nitrogen, but the mutant did not. Acetamidase/formamidase genes were found to form three distinct clades within a broad distribution of Archaea and Bacteria. Genes were present within lineages characterized by aerobic growth in low nutrient environments (e.g. haloarchaea, Starkeya) but absent from lineages containing anaerobes or facultative anaerobes (e.g. methanogens, Epsilonproteobacteria) or parasites of animals and plants (e.g. Chlamydiae). While acetamide is not a well characterized natural substrate, the build-up of plastic pollutants in the environment provides a potential source of introduced acetamide. In view of the extent and pattern of distribution of acetamidase/formamidase sequences within Archaea and Bacteria, we speculate that acetamide from plastics may promote the selection of amd/fmd genes in an increasing number of environmental microorganisms. -

Despite the advances in our understanding of microbial ecology in the past decade, important questions remain regarding the link between microbial diversity and geochemical factors under these extreme conditions. This dissertation first investigates a series of hot springs with wide ranges of temperature (26-92oC) and pH (3.72-8.2) from the Tibetan Plateau in China and the Philippines. Within each region, microbial diversity and geochemical conditions were studied using an integrated approach with 16S rRNA molecular phylogeny and a suite of geochemical analyses. In Tibetan springs, the microbial community was dominated by archaeal phylum Thaumarchaeota -
