Download or read book The microbial ferrous wheel: iron cycling in terrestrial, freshwater, and marine environments written by David Emerson and published by Frontiers E-books. This book was released on with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 15 years, there has been steady growth in work relating to the microbial iron cycle. It is now well established that in anaerobic environments coupling of organic matter utilization to Fe reduction is a major pathway for anaerobic respiration. In iron-rich circumneutral environments that exist at oxic-anoxic boundaries, significant progress has been made in demonstrating that unique groups of microbes can grow either aerobically or anaerobically using Fe as a primary energy source. Likewise, in high iron acidic environments, progress has been made in the study of communities of microbes that oxidize iron, and in understanding the details of how certain of these organisms gain energy from Fe-oxidation. On the iron scarcity side, it is now appreciated that in large areas of the open ocean Fe is a key limiting nutrient; thus, a great deal of research is going into understanding the strategies microbial cells, principally phytoplankton, use to acquire iron, and how the iron cycle may impact other nutrient cycles. Finally, due to its abundance, iron has played an important role in the evolution of Earth’s primary biogeochemical cycles through time. The aim of this Research Topic is to gather contributions from scientists working in diverse disciplines who have common interests in iron cycling at the process level, and at the organismal level, both from the perspective of Fe as an energy source, or as a limiting nutrient for primary productivity in the ocean. The range of disciplines may include: geomicrobiologists, microbial ecologists, microbial physiologists, biological oceanographers, and biogeochemists. Articles can be original research, techniques, reviews, or synthesis papers. An overarching goal is to demonstrate the environmental breadth of the iron cycle, and foster understanding between different scientific communities who may not always be aware of one another’s work.

This book was released on 2020 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a scarce but essential micronutrient for microbial growth in the marine environment, iron plays a critical role in supporting marine primary productivity and is tightly coupled to the cycling of carbon and additional macronutrients. While significant progress in recent years has been made in understanding the distribution of iron and iron-binding ligands in the marine environment, many questions remain regarding the mechanistic processes underlying these distributions. Heterotrophic bacteria serve as the primary drivers of the turnover of organic matter in the marine environment and have a significant cellular iron requirement, making them an important link between iron and carbon biogeochemical cycles. The work presented in this dissertation aims to improve our understanding of the molecular mechanisms by which heterotrophic marine bacteria acquire iron from their surroundings and the subsequent effects of their metabolic activities on both iron and carbon biogeochemical cycling. We have first developed Alteromonas macleodii ATCC 27126 as a model marine organism for the study of iron acquisition by heterotrophic bacteria. This has allowed us to characterize outer membrane TonB-dependent transporters for organically complexed forms of iron across the genus Alteromonas. This work revealed that a high diversity of iron-ligand compounds in the marine environment are potentially bioavailable. We have also utilized Alteromonas macleodii ATCC 27126 as a model organism for studying the functional role of siderophore production in iron acquisition in the marine environment. Through the insertional inactivation of the petrobactin biosynthetic pathway, we have determined that siderophore production increases the bioavailability of non-labile iron sources such as particulate minerals. Finally, in microcosm field experiments, we examined the transcriptional response of natural heterotrophic bacterial communities in the southern California Current System to iron additions demonstrating direct iron limitation of this community with consequences for downstream carbon processing. Together, this work sheds light on the role of heterotrophic bacteria at multiple points within the marine iron cycle, from the incorporation of iron into the marine environment to controlling the balance between the export and recycling of iron and macronutrients. It is our hope that this work results in an improved mechanistic understanding of marine iron biogeochemical cycling.

Book excerpt: Microbial redox cycling of iron (Fe) plays a central role in controlling terrestrial element partitioning, with broader impacts on subsurface contaminant mobility and the development of geochemical cycles on Earth. This dissertation explores the capacity of native microbial communities to oxidize and reduce Fe in terrestrial circumneutral-pH environments by coupling environmental sampling campaigns to bench-top experiments. Microbial Fe-oxide reduction can result in magnetite production, potentially explaining magnetite in Precambrian sedimentary rocks. The only modern analog occurs in sediments at the Bay of Vidy (Lake Geneva, Switzerland), where in situ magnetite formation is directly associated with microbial reduction. Geochemistry and isotope composition of Fe in these sediments was investigated. Despite extensive microbial reduction, very little Fe isotope variation was observed, indicating Fe isotope homogeneity is not sufficient to rule out a biological mechanism for magnetite formation. Microbial oxidation of solid-phase Fe(II) at circumneutral pH is a key pathway in controlling element partitioning and contaminant stability in modern terrestrial environments. Experimental reactors were constructed with sediment from a contaminated subsurface environment (Hanford 300 Area, Richland, WA) to determine how native microbes responded to oxidant flux. Endogenous microbial communities rapidly responded to chemical oxidant input (O2 or NO3) concurrently stabilizing. Uninoculated oxic reactors showed significant Fe(II) oxidation, enhancing our understanding of the capacity for native microbes in subsurface sediment to maintain redox state. A second series of reactors explored the capacity of native microbes to oxidize solid-phase Fe minerals. The first microbial cultures capable of aerobic pyrite (FeS2) oxidation at circumneutral pH were recovered. These enrichment cultures demonstrated growth tied to pyrite oxidation and sulfate generation for over one year of repeated transfers. Aerobic pyrite oxidation has been proposed to be a dominant pathway in Precambrian sulfur cycling. The mineralogical, microbiological, and geochemical changes observed in these experiments shed light on the role of microbes in sulfur cycling in ancient and modern subsurface environments. Finally, my Teaching and Learning Portfolio, the capstone requirement for the Delta Program's Certificate in Research, Teaching, and Learning, is included to highlight some of the broader impacts of my graduate career.

Available in PDF, EPUB and Kindle. Book excerpt: 2012 PROSE Award, Earth Science: Honorable Mention For more than fifty years scientists have been concerned with the interrelationships of Earth and life. Over the past decade, however, geobiology, the name given to this interdisciplinary endeavour, has emerged as an exciting and rapidly expanding field, fuelled by advances in molecular phylogeny, a new microbial ecology made possible by the molecular revolution, increasingly sophisticated new techniques for imaging and determining chemical compositions of solids on nanometer scales, the development of non-traditional stable isotope analyses, Earth systems science and Earth system history, and accelerating exploration of other planets within and beyond our solar system. Geobiology has many faces: there is the microbial weathering of minerals, bacterial and skeletal biomineralization, the roles of autotrophic and heterotrophic metabolisms in elemental cycling, the redox history in the oceans and its relationship to evolution and the origin of life itself.. This book is the first to set out a coherent set of principles that underpin geobiology, and will act as a foundational text that will speed the dissemination of those principles. The chapters have been carefully chosen to provide intellectually rich but concise summaries of key topics, and each has been written by one or more of the leading scientists in that field.. Fundamentals of Geobiology is aimed at advanced undergraduates and graduates in the Earth and biological sciences, and to the growing number of scientists worldwide who have an interest in this burgeoning new discipline.

This book was released on 2017-09-29 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Igneous oceanic crust is one of the largest potential habitats for life on earth, and microbial activity supported by rock-water-microbe reactions in this environment can impact global biogeochemical cycles. However, our understanding of the microbiology of this system, especially the subsurface “deep biosphere” component of it, has traditionally been limited by sample availability and quality. Over the past decade, several major international programs (such as the Center for Dark Energy Biosphere Investigations, the current International Ocean Discovery Program and its predecessor Integrated Ocean Drilling Program, and the Deep Carbon Observatory) have focused on advancing our understanding of life in this cryptic, yet globally relevant, biosphere. Additionally, many field and laboratory research programs are examining hydrothermal vent systems –a seafloor expression of seawater that has been thermally and chemically altered in subseafloor crust – and the microbial communities supported by these mineral-rich fluids. The Frontiers in Microbiology 3 September 2017 | Recent Advances in Geomicrobiology of the Ocean Crust papers in this special issue bring together recent discoveries of microbial presence, diversity and activity in these dynamic ocean environments. Cumulatively, the articles in this special issue serve as a tribute to the late Dr. Katrina J. Edwards, who was a pioneer and profound champion of studying microbes that “rust the crust”. This special issue volume serves as a foundation for the continued exploration of the subsurface ocean crust deep biosphere.
