Book Description
Inorganic polyphosphates - polymers of orthophosphate linked by high-energy phosphoanhydride bonds - have been found in apparently all forms of life, from bacteria, yeasts and fungi to higher plants and animals. These polymers, which had been neglected for a long time, have become a fascinating area of research in the last few years. This volume summarizes the present state of knowledge about the metabolism and function of inorganic polyphosphates. In addition, the methods to study these polymers as well as the biotechnological applications of inorganic polyphosphates are described. The 15 chapters of this volume, dealing with different aspects of polyphosphate research, are written by experts in the field. This book represents a valuable source of information not only for researchers working on this subject, but also for scientists interested in fundamental aspects of cell and energy metabolism.

Book Description
Dr. Heinonen reviews and critically evaluates the scientific literature on the biological role of inorganic pyrophosphate (PPi ) published from 1940 to the end of 1999. He describes and classifies all known biochemical reactions that produce Ppi; describes and evaluates all published methods used in biological Ppi; and compiles and critically evaluates information on the concentration of PPi (with the conclusion that, contrary to common belief, PPi exists throughout the living world in rather high concentrations). Many reactions in which PPi is used as a biochemical energy source instead of ATP have been described in recent decades, especially in bacteria, protists, and plants. These reactions are evaluated from the bioenergetic and regulatory points of view. Also considered is the possible role of PPi as a source of biochemical energy in the primitive phases of life, before ATP. Data is presented on the regulatory role of PPi in living systems, such as activities of enzymes, fidelity of syntheses of macromolecules, and proliferation of cells. PPi may also regulate the formation and dissolution of bone as well as pathologic calcification of soft tissues and the formation of urinary stones. The formation of calcium pyrophosphate dihydrate crystals in the extracellular fluids of joints cause the disease called pseudogout. Biological Role of Inorganic Pyrophosphate book is a unique and invaluable source of references (about 1120) and summarized data for professionals who study or plan to study the role of PPi in living systems. Many different branches of science (biochemistry, microbiology, bioenergetics, plant physiology, parasitology, evolution, orthopedics, rheumatology) have involvement with PPi. This book sums up available knowledge in one place and will help scientists cross disciplinary boundaries.

Book Description
Enzymes are indispensable tools in recombinant DNA technology and genetic engineering. This book not only provides information for enzymologists, but does so in a manner that will also aid nonenymologists in making proper use of these biocatalysts in their research. The Enzymology Primer for Recombinant DNA Technology includes information not usually found in the brief descriptions given in most books on recombinant DNA methodology and gene cloning. - Provides essential basics as well as up-to-date information on enzymes most commonly used in recombinant DNA technology - Presents information in an easily accessible format to serve as a quick reference source - Leads to a better understanding of the role of biocatalysts in recombinant DNA techniques

Book Description
The value of studies of monotypic populations is constantly argued in bacterial ecology. The controversy itself is evidenceofthe strong awareness that bacterial activities in natural sites are not determined by the bacteria alone. At the same time, the best evidence that bacteria are influenced by environmental factors is the contrast between their behavior in laboratory cultures and their relatively subdued influence when in the presence of com petitors, predators, and fluctuating-often stressful-environmental conditions. Monotypic populations are admittedly reductionist, but are not therefore irrelevant to bacterial ecology. Quite the contrary. Without pure culture studies, our understanding of important and applicable bacterial activities-N fixation, for example-would still be z limited to what we could discern from a comparison of events in steamed vis-a-vis un heated soil. As was evident throughout the previous volume in this treatise, practically any method of studying natural bacterial communities upsets them while permitting only limited assessment of the respective qualities and quantitative contributions to total com munity activity of each type of bacterium present. Total activity itself is difficult to assess and is not dependably accomplished by any single method. This third volume comprises information regarding the properties of bacteria as they have been learned largely from pure culture studies. Its purpose is twofold: to provide readers with fundamental information regarding the cellular organization, physiological capabilities, and genetic systems of bacteria; and to connect known bacterial properties with environmental influences on them and with their influences on natural processes.

Book Description
The International Committee on Microbial Ecology (ICOME) sponsors both the Interna tional Symposium on Microbial Ecology, held in various parts of the world at three-year intervals, and the publication of Advances in Microbial Ecology. Advances was estab lished to provide a vehicle for in-depth, critical, and even provocative reviews in microbial ecology and is now recognized as a major source of information for both practicing and prospective microbial ecologists. The Editorial Board of Advances nor mally solicits contributions from established workers in particular areas of microbial ecology, but individuals are encouraged to submit outlines of unsolicited contributions to any member of the Editorial Board for consideration for pUblication in Advances. Chapters in Volume 11 of Advances in Microbial Ecology include those on micro bial transformations of chitin by G. W. Gooday, organic sulfur compounds by D. P. Kelly and N. A. Smith, and phosphorus, including its removal in waste water treatment plants, by D. F. Toerien, A. Gerber, L. H. Lotter, and T. E. Cloete. The importance of diffusion processes in microbial ecology is discussed by A. L. Koch, and 1. I. Prosser reviews the application of mathematical modeling to nitrification processes. Considera tions of particular ecosystems include the Antarctic by D. D. Wynn-Williams and Australian coastal microbial mats by G. W. Skyring and 1. Bauld. Other chapters include the regulation of N2 fixation by H. W.
