Abstract

Research on biogas-producing microbial communities aims at elucidation of correlations and dependencies between the anaerobic digestion (AD) process and the corresponding microbiome composition in order to optimize the performance of the process and the biogas output. Previously,Lachnospiraceaespecies were frequently detected in mesophilic to moderately thermophilic biogas reactors. To analyze adaptive genome features of a representativeLachnospiraceaestrain,Anaeropeptidivorans aminofermentansM3/9Twas isolated from a mesophilic laboratory-scale biogas plant and its genome was sequenced and analyzed in detail. Strain M3/9Tpossesses a number of genes encoding enzymes for degradation of proteins, oligo- and dipeptides. Moreover, genes encoding enzymes participating in fermentation of amino acids released from peptide hydrolysis were also identified. Based on further findings obtained from metabolic pathway reconstruction, M3/9Twas predicted to participate in acidogenesis within the AD process. To understand the genomic diversity between the biogas isolate M3/9Tand closely relatedAnaerotignumtype strains, genome sequence comparisons were performed. M3/9Tharbors 1,693 strain-specific genes among others encoding different peptidases, a phosphotransferase system (PTS) for sugar uptake, but also proteins involved in extracellular solute binding and import, sporulation and flagellar biosynthesis. In order to determine the occurrence of M3/9Tin other environments, large-scale fragment recruitments with the M3/9Tgenome as a template and publicly available metagenomes representing different environments was performed. The strain was detected in the intestine of mammals, being most abundant in goat feces, occasionally used as a substrate for biogas production.

Abstract

The microbial biogas network is complex and intertwined, and therefore relatively stable in its overall functionality. However, if key functional groups of microorganisms are affected by biotic or abiotic factors, the entire efficacy may be impaired. Bacteriophages are hypothesized to alter the steering process of the microbial network. In this study, an enriched fraction of virus-like particles was extracted from a mesophilic biogas reactor and sequenced on the Illumina MiSeq and Nanopore GridION sequencing platforms. Metagenome data analysis resulted in identifying 375 metagenome-assembled viral genomes (MAVGs). Two-thirds of the classified sequences were only assigned to the superkingdom Viruses and the remaining third to the family Siphoviridae, followed by Myoviridae, Podoviridae, Tectiviridae, and Inoviridae. The metavirome showed a close relationship to the phage genomes that infect members of the classes Clostridia and Bacilli. Using publicly available biogas metagenomic data, a fragment recruitment approach showed the widespread distribution of the MAVGs studied in other biogas microbiomes. In particular, phage sequences from mesophilic microbiomes were highly similar to the phage sequences of this study. Accordingly, the virus particle enrichment approach and metavirome sequencing provided additional genome sequence information for novel virome members, thus expanding the current knowledge of viral genetic diversity in biogas reactors.

Abstract

Members of the genera Proteiniphilum and Petrimonas were speculated to represent indicators reflecting process instability within anaerobic digestion (AD) microbiomes. Therefore, Petrimonas mucosa ING2-E5AT was isolated from a biogas reactor sample and sequenced on the PacBio RSII and Illumina MiSeq sequencers. Phylogenetic classification positioned the strain ING2-E5AT in close proximity to Fermentimonas and Proteiniphilum species (family Dysgonomonadaceae). ING2-E5AT encodes a number of genes for glycosyl-hydrolyses (GH) which are organized in Polysaccharide Utilization Loci (PUL) comprising tandem susCD-like genes for a TonB-dependent outer-membrane transporter and a cell surface glycan-binding protein. Different GHs encoded in PUL are involved in pectin degradation, reflecting a pronounced specialization of the ING2-E5AT PUL systems regarding the decomposition of this polysaccharide. Genes encoding enzymes participating in amino acids fermentation were also identified. Fragment recruitments with the ING2-E5AT genome as a template and publicly available metagenomes of AD microbiomes revealed that Petrimonas species are present in 146 out of 257 datasets supporting their importance in AD microbiomes. Metatranscriptome analyses of AD microbiomes uncovered active sugar and amino acid fermentation pathways for Petrimonas species. Likewise, screening of metaproteome datasets demonstrated expression of the Petrimonas PUL-specific component SusC providing further evidence that PUL play a central role for the lifestyle of Petrimonas species.

Abstract

Obesity is a genetically heterogeneous disorder. Using targeted and whole-exome sequencing, we studied 32 human and 87 rodent obesity genes in 2,548 severely obese children and 1,117 controls. We identified 52 variants contributing to obesity in 2% of cases including multiple novel variants in GNAS, which were sometimes found with accelerated growth rather than short stature as describedw previously. Nominally significant associations were found for rare functional variants in BBS1, BBS9, GNAS, MKKS, CLOCK and ANGPTL6. The p.S284X variant in ANGPTL6 drives the association signal (rs201622589, MAF∼0.1%, odds ratio = 10.13, p-value = 0.042) and results in complete loss of secretion in cells. Further analysis including additional case-control studies and population controls (N = 260,642) did not support association of this variant with obesity (odds ratio = 2.34, p-value = 2.59 × 10-3), highlighting the challenges of testing rare variant associations and the need for very large sample sizes. Further validation in cohorts with severe obesity and engineering the variants in model organisms will be needed to explore whether human variants in ANGPTL6 and other genes that lead to obesity when deleted in mice, do contribute to obesity. Such studies may yield druggable targets for weight loss therapies.

Abstract

The increasing amount of next-generation sequencing data introduces a fundamental challenge on large scale genomic analytics. Storing and processing large amounts of sequencing data requires considerable hardware resources and efficient software that can fully utilize these resources. Nowadays, both industrial enterprises and nonprofit institutes are providing robust and easy-access cloud services for studies in life science. To facilitate genomic data analyses on such powerful computing resources, distributed bioinformatics tools are needed. However, most of existing tools have low scalability on the distributed computing cloud. Thus, in this thesis, I developed a cloud based bioinformatics framework that mainly addresses two computational challenges: (i) the run time intensive challenge in the sequence mapping process and (ii) the memory intensive challenge in the de novo genome assembly process. For sequence mapping, I have natively implemented an Apache Spark based distributed sequence mapping tool called Sparkhit. It uses the q-gram filter and Pigeonhole principle to accelerate the speeds of fragment recruitment and short read mapping processes. These algorithms are implemented in the Spark extended MapReduce model. Sparkhit runs 92–157 times faster than MetaSpark on metagenomic fragment recruitment and 18–32 times faster than Crossbow on data pre-processing. For de novo genome assembly, I have invented a new data structure called Reflexible Distributed K-mer (RDK) and natively implemented a distributed genome assembler called Reflexiv. Reflexiv is built on top of the Apache Spark platform, uses Spark Resilient Distributed Dataset (RDD) to distributed large amount of k-mers across the cluster and assembles the genome in a recursive way. As a result, Reflexiv runs 8-17 times faster than Ray assembler and 5-18 times faster than AbySS assembler on the clusters deployed at the de.NBI cloud. In addition, I have incorporated a variety of analytical methods into the framework. I have also developed a tool wrapper to distribute external tools and Docker containers on the Spark cluster. As a large scale genomic use case, my framework processed 100 terabytes of data across four genomic projects on the Amazon cloud in 21 hours. Furthermore, the application on the entire Human Microbiome Project shotgun sequencing data was completed in 2 hours, presenting an approach to easily associate large amounts of public datasets with reference data. Thus, my work contributes to the interdisciplinary research of life science and distributed cloud computing by improving existing methods with a new data structure, new algorithms, and robust distributed implementations.

Abstract

M. Kivimäki työryhmäjäsen. The contribution of rare and low-frequency variants to human traits is largely unexplored. Here we describe insights from sequencing whole genomes (low read depth, 7x) or exomes (high read depth, 80x) of nearly 10,000 individuals from population-based and disease collections. In extensively phenotyped cohorts we characterize over 24 million novel sequence variants, generate a highly accurate imputation reference panel and identify novel alleles associated with levels of triglycerides (APOB), adiponectin (ADIPOQ) and low-density lipoprotein cholesterol (LDLR and RGAG1) from single-marker and rare variant aggregation tests. We describe population structure and functional annotation of rare and low-frequency variants, use the data to estimate the benefits of sequencing for association studies, and summarize lessons from disease-specific collections. Finally, we make available an extensive resource, including individual-level genetic and phenotypic data and web-based tools to facilitate the exploration of association results.

Abstract

The total synthesis of 6,8-dihydroxy-7-propyl-9H-pyrrolo[1,2-b][1,3]benzoxazin-9-one, a novel antibacterial agent, is described. The key step in the synthesis is achieved via an oxidative cyclization of a phenol to the 2-position of a pyrrole using stoichiometric Pd(OAc)2. This provides a straightforward approach to the tricyclic structure of this prevously unreported template and future derivatives.

Abstract

Bacterial resistance to the currently available antibiotics is a worldwide problem with catastrophic potential (Kunin, 1993; Berkowitz, 1995; Domagala and Sanchez, 1997). In the US, overall mortality from infectious diseases has increased 58% with deaths from respiratory infections and septicemia up 20 and 83% respectively (Pinner et al., 1996). Increased resistance has been documented for every major group of pathogens with methicillin resistant Staphyloccus aureus (MRSA), vancomycin resistant enterococci (VRE) and β-lactam resistant streptococci causing the greatest alarm (Cormican and Jones, 1996; Howe et al., 1996). In fact, VRE has been described as the most feared nosocomial pathogen today (Hagman and Strausbaugh, 1996). The fear of vancomycin resistant MRS A has sparked calls for stringent preemptive controls (Edmund et al., 1996). Equally alarming is the dramatic increase in resistance among the gram negative organisms (Jones, 1996). Nosocomial pneumonias (often with resistant organisms) occur in 0.5–5% of all hospitalized patients with a mortality of 20–70%, and an added annual cost of $2.5 billion for increased care and treatment (Gaynes and Lynch, 1991; Swartz, 1994). So great and urgent is the problem that the prestigious journal Science has devoted two issues to bacterial resistance (Travis, 1994; Koshland, 1992), and the American Society for Microbiology formed a Task Force to define the problem and make recommendations. Their insightful report, issued in 1995 (Report 1995), called for an increased effort in the discovery of new drugs and new drug targets in bacteria.
