Molecular hydrogen (H2) is an important molecule in the metabolism of diverse microorganisms. It is used either as energy source or for the disposal of reducing equivalents depending on environmental conditions. Furthermore, H2 transmits energy between different species within microbial communities. The enzymes that split or evolve H2 are called hydrogenases and these metalloproteins can be divided into three phylogenetically unrelated classes distinguishable by the metal composition of their active sites, namely [Fe]-, [FeFe]-, and [NiFe]- hydrogenases. Following a century of hydrogenase research, it is now possible to isolate, handle, and investigate these fragile enzymes. There have been numerous advances in understanding the regulation, function, structures, and maturation of these enzymes, as well as their involvement in important processes such as microbial pathogenesis and biogeochemical cycling. The employment of hydrogenases and hydrogenase-based applications could also potentially facilitate the world’s transition to a future sustainable H2-based energy economy.

This is a textbook covering the transition from energy releasing reactions on the early Earth to energy releasing reactions that fueled growth in the first microbial cells. It is for teachers and college students with an interest in microbiology, geosciences, biochemistry, evolution, or all of the above. The scope of the book is a quantum departure from existing “origin of life” books in that it starts with basic chemistry and links energy-releasing geochemical processes to the reactions of microbial metabolism. The text reaches across disciplines, providing students of the geosciences an origins/biology interface and bringing a geochemistry/origins interface to students of microbiology and evolution. Beginning with physical chemistry and transitioning across metabolic networks into microbiology, the timeline documents chemical events and organizational states in hydrothermal vents – the only environments known that bridge the gap between spontaneous chemical reactions that we can still observe in nature today and the physiology of microbes that live from H2, CO2, ammonia, phosphorus, inorganic salts and water. Life is a chemical reaction. What it is and how it arose are two sides of the same coin. Key Features Provides clear connections between geochemical reactions and microbial metabolism Focuses on chemical mechanisms and transition metals Richly illustrated with color figures explaining reactions and processes Covers the origin of the Earth, the origin of metabolism, the origin of protein synthesis and genetic information as well as the escape into the wild of the first free-living cells: Bacteria and Archaea

Microalgae could play an important role in the achievement of sustainability goals related to the generation of renewable energy and greenhouse gas (GHG) emissions. These photosynthetic microorganisms are able to capture CO2 and, therefore, can be used to produce biofuels such as ethanol, methane and green diesel. Other factors, such as their high growth rate, ability to use wastewater as a culture medium and the ability to grow on non-arable land makes them a potentially economical source of biofuel production on a large scale. This monograph introduces the reader to the basic and applied science of microalgal biofuel production. Chapters in the volume give information about bioethanol and biogas production from microalgal sources, the fermentation process, optimization of culture parameters and industrial applications of biomass projects. The book is a useful reference for biotechnology and environmental science graduates and professionals interested in biofuel production.

The central theme of this book “Microbial BioEnergy: Hydrogen Production” is focused on the biological machinery that microorganisms use to produce hydrogen gas. The book summarizes the achievements over the past decade in the biochemistry, structural and molecular biology, genomics and applied aspects of microbial H2-production, including microbial fuel cells (MFC), by phototrophs such as purple sulfur and non-sulfur bacteria (Thiocapsa spp., Rhodobacter and Rhodopseudomonas spp.) microalgae (Chlamydomonas) and cyanobacteria (Anabaena spp.) along with anaerobes and thermophiles such as Caldicellulosiruptor and Thermotoga. This is the first book of this series entirely devoted to microbial bio-hydrogen production and is intended to be a precious source of information for PhD students, researchers and undergraduates from disciplines such as microbiology, biochemistry, biotechnology, photochemistry and chemical engineering, interested in basic and applied sciences.

Several evolutionary models proposed that molecular hydrogen (H2) was the primary energy source on the early Earth, exerting a major influence on the origin of life. Hydrogenase, the enzyme catalyzing the interconversion of H2 into protons and electrons, is thus considered an ancestral invention, for which the molecular structure and architecture have been thoroughly adapted for specialized tasks, undertaken in peculiar environments, during the course of the evolution. Three different types of hydrogenase can be distinguished on the basis of the metal content of their active site, namely, [NiFe]-hydrogenase, [FeFe]-hydrogenase, and [Fe]-hydrogenase. Although they share common features, taxonomic distribution, maturation apparatus, and physiological role differ substantially among the three different classes of hydrogenases. These metalloenzymes are thus considered a classical example of convergent evolution. The notion that “there is much to learn from nature” holds great promise for biohydrogen applications, and this has been demonstrated by the emergence of bioengineering strategies used to design synthetic metabolic pathways and improve the O2 tolerance of hydrogenases. This chapter provides an overview of the diversity and physiological role of hydrogenases, with a particular emphasis on their biotechnological potential.
