    Metagenomic Analysis of Low-Temperature Environments2017In: Psychrophiles: From Biodiversity to Biotechnology / [ed] Rosa Margesin, Cham: Springer, 2017, 389-421 p.Chapter in book (Refereed)
    Abstract [en]

    The Earth’s permanently cold biosphere is known to harbour abundant microbial biomass and represents a rich resource for the discovery of novel cold-adapted microorganisms, many of which form part of the ‘microbial dark matter’ which cannot be analysed using traditional culture-dependent approaches. The recent development of metagenomics and related multi-omics strategies has provided a means by which entire microbial communities can be studied directly, without the prerequisite of culturing. The advancement of the ‘omic’ methods is directly linked to recent progress in high-throughput sequencing, robust data processing capabilities and the application of cutting-edge analytical tools for high-throughput detection of biomolecules. The combined application of these tools and strategies has provided an unprecedented access to the structure and potential function of microbial communities in cold environments, providing increasingly comprehensive insights into the taxonomic richness and functional capacity of the indigenous microorganisms. Applications of ‘omic’ strategies have enhanced our understanding of psychrophilic adaptation mechanisms, revealing the versatility and adaptability of life in the ‘cryosphere’. In addition to the predicted roles of psychrophiles in biogeochemical cycling, recent multi-omic studies have further emphasised the importance of the ‘cryosphere’ in influencing global atmospheric conditions. Finally, metagenomic bioprospecting of cold environments has yielded a variety of novel bioactive molecules including novel ‘psychrozymes’, with a wide range of potential industrial and biotechnological applications. Here, we have provided an overview of recent developments in metagenomic technologies and their application in the study of the cold biosphere.

    Production and characterization of a novel antifungal chitinase identified by functional screening of a suppressive-soil metagenome2017In: Microbial Cell Factories, ISSN 1475-2859, E-ISSN 1475-2859, Vol. 16, no 1, 16Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Through functional screening of a fosmid library, generated from a phytopathogen-suppressive soil metagenome, the novel antifungal chitinase-named Chi18H8 and belonging to family 18 glycosyl hydrolases-was previously discovered. The initial extremely low yield of Chi18H8 recombinant production and purification from Escherichia coli cells (21 μg/g cell) limited its characterization, thus preventing further investigation on its biotechnological potential.

    RESULTS: We report on how we succeeded in producing hundreds of milligrams of pure and biologically active Chi18H8 by developing and scaling up to a high-yielding, 30 L bioreactor process, based on a novel method of mild solubilization of E. coli inclusion bodies in lactic acid aqueous solution, coupled with a single step purification by hydrophobic interaction chromatography. Chi18H8 was characterized as a Ca(2+)-dependent mesophilic chitobiosidase, active on chitin substrates at acidic pHs and possessing interesting features, such as solvent tolerance, long-term stability in acidic environment and antifungal activity against the phytopathogens Fusarium graminearum and Rhizoctonia solani. Additionally, Chi18H8 was found to operate according to a non-processive endomode of action on a water-soluble chitin-like substrate.

    CONCLUSIONS: Expression screening of a metagenomic library may allow access to the functional diversity of uncultivable microbiota and to the discovery of novel enzymes useful for biotechnological applications. A persisting bottleneck, however, is the lack of methods for large scale production of metagenome-sourced enzymes from genes of unknown origin in the commonly used microbial hosts. To our knowledge, this is the first report on a novel metagenome-sourced enzyme produced in hundreds-of-milligram amount by recovering the protein in the biologically active form from recombinant E. coli inclusion bodies.

    Metagenomic Analysis of Subtidal Sediments from Polar and Subpolar Coastal Environments Highlights the Relevance of Anaerobic Hydrocarbon Degradation Processes2017In: Microbial Ecology, ISSN 0095-3628, E-ISSN 1432-184XArticle in journal (Refereed)
    Abstract [en]

    In this work, we analyzed the community structure and metabolic potential of sediment microbial communities in high-latitude coastal environments subjected to low to moderate levels of chronic pollution. Subtidal sediments from four low-energy inlets located in polar and subpolar regions from both Hemispheres were analyzed using large-scale 16S rRNA gene and metagenomic sequencing. Communities showed high diversity (Shannon's index 6.8 to 10.2), with distinct phylogenetic structures (<40% shared taxa at the Phylum level among regions) but similar metabolic potential in terms of sequences assigned to KOs. Environmental factors (mainly salinity, temperature, and in less extent organic pollution) were drivers of both phylogenetic and functional traits. Bacterial taxa correlating with hydrocarbon pollution included families of anaerobic or facultative anaerobic lifestyle, such as Desulfuromonadaceae, Geobacteraceae, and Rhodocyclaceae. In accordance, biomarker genes for anaerobic hydrocarbon degradation (bamA, ebdA, bcrA, and bssA) were prevalent, only outnumbered by alkB, and their sequences were taxonomically binned to the same bacterial groups. BssA-assigned metagenomic sequences showed an extremely wide diversity distributed all along the phylogeny known for this gene, including bssA sensu stricto, nmsA, assA, and other clusters from poorly or not yet described variants. This work increases our understanding of microbial community patterns in cold coastal sediments, and highlights the relevance of anaerobic hydrocarbon degradation processes in subtidal environments.

    Prospecting Biotechnologically-Relevant Monooxygenases from Cold Sediment Metagenomes: An In Silico Approach2017In: Marine Drugs, ISSN 1660-3397, E-ISSN 1660-3397, Vol. 15, no 4, 114Article in journal (Refereed)
    Abstract [en]

    The goal of this work was to identify sequences encoding monooxygenase biocatalysts with novel features by in silico mining an assembled metagenomic dataset of polar and subpolar marine sediments. The targeted enzyme sequences were Baeyer-Villiger and bacterial cytochrome P450 monooxygenases (CYP153). These enzymes have wide-ranging applications, from the synthesis of steroids, antibiotics, mycotoxins and pheromones to the synthesis of monomers for polymerization and anticancer precursors, due to their extraordinary enantio-, regio-, and chemo- selectivity that are valuable features for organic synthesis. Phylogenetic analyses were used to select the most divergent sequences affiliated to these enzyme families among the 264 putative monooxygenases recovered from the ~14 million protein-coding sequences in the assembled metagenome dataset. Three-dimensional structure modeling and docking analysis suggested features useful in biotechnological applications in five metagenomic sequences, such as wide substrate range, novel substrate specificity or regioselectivity. Further analysis revealed structural features associated with psychrophilic enzymes, such as broader substrate accessibility, larger catalytic pockets or low domain interactions, suggesting that they could be applied in biooxidations at room or low temperatures, saving costs inherent to energy consumption. This work allowed the identification of putative enzyme candidates with promising features from metagenomes, providing a suitable starting point for further developments.

    A communal catalogue reveals Earth’s multiscale microbial diversity2017In: Nature, ISSN 0028-0836, E-ISSN 1476-4687, Vol. 551, 457-463 p.Article in journal (Refereed)
    Abstract [en]

    Our growing awareness of the microbial world's importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth's microbial diversity.

    Reconstructing ecosystem functions of the active microbial community of the Baltic Sea oxygen depleted sediments2016In: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, Vol. 4, e1593Article in journal (Refereed)
    Abstract [en]

    Baltic Sea deep water and sediments hold one of the largest anthropogenically induced hypoxic areas in the world. High nutrient input and low water exchange result in eutrophication and oxygen depletion below the halocline. As a consequence at Landsort Deep, the deepest point of the Baltic Sea, anoxia in the sediments has been a persistent condition over the past decades. Given that microbial communities are drivers of essential ecosystem functions we investigated the microbial community metabolisms and functions of oxygen depleted Landsort Deep sediments by metatranscriptomics. Results show substantial expression of genes involved in protein metabolism demonstrating that the Landsort Deep sediment microbial community is active. Identified expressed gene suites of metabolic pathways with importance for carbon transformation including fermentation, dissimilatory sulphate reduction and methanogenesis were identified. The presence of transcripts for these metabolic processes suggests a potential for heterotrophic-autotrophic community synergism and indicates active mineralisation of the organic matter deposited at the sediment as a consequence of the eutrophication process. Furthermore, cyanobacteria, probably deposited from the water column, are transcriptionally active in the anoxic sediment at this depth. Results also reveal high abundance of transcripts encoding integron integrases. These results provide insight into the activity of the microbial community of the anoxic sediment at the deepest point of the Baltic Sea and its possible role in ecosystem functioning.

    A dark, anoxic mausoleum for DNA: perceived and actual community structure in the Landsort Deep sediment, the Baltic Sea2016In: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359Article in journal (Other academic)
    Abstract [en]

    Numerous investigations of bacterial communities using sequence analysis of environmental DNA have revealed extensive diversity of microbial taxa in an array of different environmental habitats. Community analysis based solely on DNA, however, does not reveal whether the detected community members are actively contributing to community functioning, or whether they are dormant or remnants of dead cells. This dilemma is of particular concern when analyzing microbial community structure of sites with a high degree of deposited matter, such as marine sediments. For example, the Baltic Sea’s deepest point, the Landsort Deep, consists of anoxic sediments with a large deposition of allochthonous organic matter from the highly stratified 460 m water column above. Our previous metagenomics results indicated the presence of potential obligately aerobic and phototrophic microorganisms. To further elucidate which taxa may contribute to ecosystem function at this site, we here present three different datasets – rDNA amplicons, rDNA reads from a shotgun metagenome and expressed rRNA from a shotgun metatranscriptome. By comparing the three datasets and the ratios between rRNA and rDNA we seek to estimate the protein synthesis potential of the community members in order to provide an indication of what taxa may have cellular activity and metabolic potential. The variation in protein synthesis potential was large, both within and between taxa, in the sediment community. Many typically anaerobic taxa, e.g. from Deltaproteobacteria and Euryarchaeota, showed a high protein synthesis potential, while typical aerobes like Flavobacteria showed a low protein synthesis potential. More surprisingly, some common Baltic Sea surface water bacteria also displayed a high protein synthesis potential, suggesting they have an active role in the anoxic sediment ecosystem at 460 m depth. Both filamentous and unicellular Cyanobacteria exhibited very high protein synthesis potential, which implies a more complex role of these bacteria in carbon cycling in the Baltic Sea than previously suggested. Moreover, Mycobacteria, that were abundant in Landsort Deep sediment metagenome compared with other marine sediment metagenomes, showed protein synthesis potentials consistent with a functional role in the sediment community. Our results provide a new window of insight into the complexities of the microbial community of Landsort Deep with implications for the understanding of other anoxic accumulation sediments.

    A Metagenomics Transect into the Deepest Point of the Baltic Sea Reveals Clear Stratification of Microbial Functional Capacities2013In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, no 9, e74983Article in journal (Refereed)
    Abstract [en]

    The Baltic Sea is characterized by hyposaline surface waters, hypoxic and anoxic deep waters and sediments. These conditions, which in turn lead to a steep oxygen gradient, are particularly evident at Landsort Deep in the Baltic Proper. Given these substantial differences in environmental parameters at Landsort Deep, we performed a metagenomic census spanning surface to sediment to establish whether the microbial communities at this site are as stratified as the physical environment. We report strong stratification across a depth transect for both functional capacity and taxonomic affiliation, with functional capacity corresponding most closely to key environmental parameters of oxygen, salinity and temperature.

    We report similarities in functional capacity between the hypoxic community and hadal zone communities, underscoring the substantial degree of eutrophication in the Baltic Proper. Reconstruction of the nitrogen cycle at Landsort deep shows potential for syntrophy between archaeal ammonium oxidizers and bacterial denitrification at anoxic depths, while anaerobic ammonium oxidation genes are absent, despite substantial ammonium levels below the chemocline. Our census also reveals enrichment in genetic prerequisites for a copiotrophic lifestyle and resistance mechanisms reflecting adaptation to prevalent eutrophic conditions and the accumulation of environmental pollutants resulting from ongoing anthropogenic pressures in the Baltic Sea.
