Book Description
Fifteen leading scientists active in research on the chemistry, microbiology, enzymology, and genetics of coal biotransformation summarize knowledge of the mechanisms by which bacteria and fungi metabolize the macromolecular structure of lignite coals. They also explore the potential for developing commercially viable biotransformations of low rank coals into useful chemicals and clean-burning liquid and gaseous fuels. Microbial Transformations of Low Rank Coals reviews the types of aerobic and anaerobic microbes known to transform fuel and discusses the relative potential of aerobic versus anaerobic organisms. Biochemical mechanisms used by microorganisms to solubilize, depolymerize, liquify, and gasify coal are examined. The book also reviews the potential for using microorganisms to remove organic sulfur from coal and the potential for using genetic engineering to improve coal biotransforming microorganisms.

Book Description
Effective remediation of polluted environments is a priority in both Eastern and Western countries. In the U.S. and Europe, remediation costs generally exceed the net economic value of the land. As a result, scientists and engineers on both sides of the Atlantic have aggressively tried to develop novel technologies to meet regulatory standards at a fraction of the costs. In situ remediation shows considerable promise from both technical and economic perspectives. In situ technologies that deploy natural attenuating agents such as humic substances (HS) may be even more cost effective. Numerous studies have shown humics capable of altering both the chemical and the physical speciation of the ecotoxicants and in turn attenuate potential adverse environmental repercussions. Furthermore, the reserves of inexpensive humic materials are immense. Which suggests HS portend great promise as inexpensive amendments to mitigate the environmental impacts of ecotoxicants and as active agents in remediation. To elucidate emerging concepts of humics-based remediation technologies, we organized the NATO Advanced Research Workshop (ARW), entitled "Use of humates to remediate polluted environments: from theory to practice", held on September 23-29, 2002 in Zvenigorod, Russia (see the web-site http://www.mgumus.chem.msu.ru/arw).

Book Description
Mycology, the study of fungi, originated as a subdiscipline of botany and was a descrip tive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgeff, Kniep and Lindegren are all associated with this early period of fungal genetics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.

Book Description
Maintaining the qualities that sent previous editions into multiple printings, this edition continues to explore the role that microbes have played in specific geological processes. The author discusses acidophilic iron-oxidizing bacteria, acidophilic iron- and metal sulfide-oxidation, and the geomicrobiology of bauxites. He covers geomicrobial methods, mineral formation and transformation, biodegradation or transformation of organics and inorganics, carbonates, silicates, phosphates, metal-oxides, and metal-sulfides, and practical applications of geomicrobial processes. The book includes end-of-chapter summaries, 2800 up-to-date literature citations, and a glossary.
