Since the general recognition of the Archaebacteria, research into the evolution, metabolism, molecular biology and ecological roles of these fastidious anaerobes has proceeded at an ever-increasing pace. All possess a very novel biochemistry and many exploit unique ecological niches. Methanogens, which convert one-and-two carbon compounds into the important atmospheric gas methane, are the largest group among the Archaebacteria. Of all microbial groups, methanogens provide perhaps the best opportunity to study evolution because of their phyologenetic diversity and unique biochemistry. Today, the analysis of methanogens is at a threshold. Molecular-biological studies of these microorganisms are revealing more and more processes unique to this group, and in turn, studies of methanogens are providing new perspectives to the broader fields of biochemistry and molecular biology. This volume is the first book to be published on methanogenesis, and it will provide the reader with a comprehensive view of the field and point to future trends.

Seeming sometimes more like science fiction than science, anaerobic bacteria have been at the center of a number of exciting new discoveries. This volume discusses and explains the diversity of metabolism, modes of protein transport, molecular biology and physiology of these unusual microbes. It has practical applications ranging from wastewater treatment to clinical diagnosis and treatment of medical conditions.

During the past twenty years, multitudes of exciting discoveries in the field of anaerobic bacteria have been made. BIOCHEMISTRY AND PHYSIOLOGY OF ANAEROBIC BACTERIA explores the full range of these microorganisms. Many anaerobes have been found to have the uniquely fascinating quality of being able to survive, indeed even thrive, in extreme environments. Anaerobic bacteria often do not require oxygen, can survive extremes in temperature, and can withstand the presence of toxins and heavy metals. In addition, these organisms have very different metabolic processes than "conventional" microorganisms. The wide diversity of metabolism in anaerobes is only part of the story. They have distinct energies, cytochromes, electron transport proteins, hydrogenases and dohydrogenases. Their molecular biology, physiology, and ability to use many types of electron receptors (CO2, sulfur, nitrogen and metal oxides) are also extraordinary. With practical applications ranging from wastewater treatment to food storage issues, clinical diagnosis and treatment of a wide range of medical conditions to decontamination of heavy metal exposures BIOCHEMISTRY AND PHYSIOLOGY OF ANAEROBIC BACTERIA will prove indispensable to researchers and students alike.
