Book Description
Microorganisms are central to the cycling of methane on Earth. The anaerobic oxidation of methane (AOM) is a globally important process in anoxic marine sediments, which is often coupled to the reduction of sulfate by anaerobic methanotroph (ANME) archaea and sulfate reducing bacteria (SRB). However, the environmental and geochemical conditions that constrain these microbial communities remain largely uncharacterized. In this dissertation, I present evidence that methane and C2-C4 alkanes are substantial sources of metabolic energy in sedimented hydrothermal vent systems. Furthermore, these studies demonstrate that AOM and C2-C4 alkane oxidation linked to sulfate reduction (SR) are governed by temperature and substrate availability.

Book Description
The papers in the "Hydrothermal Vent" e-book cover a range of microbiological research in deep and shallow hydrothermal environments, from high temperature “black smokers,” to diffuse flow habitats and episodically discharging subsurface fluids, to the hydrothermal plumes. Together they provide a snapshot of current research interests in a field that has evolved rapidly since the discovery of hydrothermal vents in 1977. Hydrothermally influenced microbial habitats and communities represent a wide spectrum of geological setting, chemical in-situ regimes, and biotic communities; the classical examples of basalt-hosted black smoker chimneys at active mid-ocean spreading centers have been augmented by hydrothermally heated and chemically altered sediments, microbiota fueled by serpentinization reactions, and low-temperature vents with unusual menus of electron donors. Environmental gradients and niches provide habitats for unusual or unprecedented microorganisms and microbial ecosystems. The discovery of novel extremophiles underscores untapped microbial diversity in hydrothermal vent microbial communities. Different stages of hydrothermal activity, from early onset to peak activity, gradual decline, and persistence of cold and fossil vent sites, correspond to different colonization waves by microorganisms as well as megafauna. Perhaps no other field in microbiology is so intertwined with the geological and geochemical evolution of the oceans, and promises so many biochemical and physiological discoveries still to be made within the unexhausted richness of extreme microbial life.

Book Description
Biodegradation mediated by indigenous microbial communities is the ultimate fate of the majority of oil hydrocarbon that enters the marine environment. The aim of this Research Topic is to highlight recent advances in our knowledge of the pathways and controls of microbially-catalyzed hydrocarbon degradation in marine ecosystems, with emphasis on the response of microbial communities to the Deepwater Horizon oil spill in the Gulf of Mexico. In this Research Topic, we encouraged original research and reviews on the ecology of hydrocarbon-degrading bacteria, the rates and mechanisms of biodegradation, and the bioremediation of discharged oil under situ as well as near in situ conditions.

Book Description
This book provides an up-to-date overview of the microbiology, biogeochemistry, and ecology of marine hydrocarbon seeps, a globally occurring habitat for specialized microorganisms and invertebrates that depend on natural hydrocarbon seepage as a food and energy source. Prominent examples include the briny hydrocarbon seeps and mud volcanoes on the continental slope of the Gulf of Mexico and in the Mediterranean, the hydrothermally heated hydrocarbon seeps at Guaymas Basin (Mexico), and the oil and gas seeps off the coast of California and in the Gulf of Mexico. Featuring topical chapters by leading researchers in the area, the book describes geological settings, chemical characteristics of hydrocarbon seepage, hydrocarbon-dependent microbial populations, and ecosystem structure and trophic networks at hydrocarbon seeps. Further, it also discusses applied aspects such as bioremediation potential (oil-degrading microorganisms).

Book Description
Vents and seeps are the epitome of life in extreme environments, but there is much more to these systems than just black smokers or hydrocarbon seeps. Many other ecosystems are characterized by moving fluids and this book provides an overview of the different habitats, their specific conditions as well as the technical challenges that have to be met when studying them. The book provides the current state of the art and will be a valuable resource for everybody that has an interest in such environments.

Book Description
Practical Handbook of Microbiology, 4th edition provides basic, clear and concise knowledge and practical information about working with microorganisms. Useful to anyone interested in microbes, the book is intended to especially benefit four groups: trained microbiologists working within one specific area of microbiology; people with training in other disciplines, and use microorganisms as a tool or "chemical reagent"; business people evaluating investments in microbiology focused companies; and an emerging group, people in occupations and trades that might have limited training in microbiology, but who require specific practical information. Key Features Provides a comprehensive compendium of basic information on microorganisms—from classical microbiology to genomics. Includes coverage of disease-causing bacteria, bacterial viruses (phage), and the use of phage for treating diseases, and added coverage of extremophiles. Features comprehensive coverage of antimicrobial agents, including chapters on anti-fungals and anti-virals. Covers the Microbiome, gene editing with CRISPR, Parasites, Fungi, and Animal Viruses. Adds numerous chapters especially intended for professionals such as healthcare and industrial professionals, environmental scientists and ecologists, teachers, and businesspeople. Includes comprehensive survey table of Clinical, Commercial, and Research-Model bacteria.

Book Description
Petroleum hydrocarbons are both a product of, and rich substrate for, microorganisms from across all Domains of life. Rooted deeply in the history of microbiology, hydrocarbons have been studied as sources of carbon and energy for microorganisms for over a century. As global demand for petroleum and its refined products continues to rise, so do challenges associated with environmental pollution, oil well souring, infrastructure corrosion, oil recovery, transport, refining, and upgrading of heavy crude oils and bitumens. Advances in genomics, synthetic biology and metabolic engineering has invigorated interest in petroleum microbial biotechnology as interest grows in technologies for in situ methane production, biodesulfurization and biodenitrogenation, bio-upgrading of heavy crudes, microbial enhanced oil recovery, corrosion control, and biocatalysts for generating value-added products. Given the complexity of the global petroleum industry and the harsh conditions in which it operates, a deeper understanding of the ecophysiology of aerobic and anaerobic microbial communities that have associations with petroleum hydrocarbons is needed if robust technologies are to be deployed successfully. This research topic highlights recent advances in microbial enhanced oil recovery, methanogenic hydrocarbon metabolism and carbon dioxide sequestration, bioremediation, microbiologically influenced corrosion, biodesulfurization, and the application of metagenomics to better understand microbial communities associated with petroleum hydrocarbons.
