Available in PDF, EPUB and Kindle. Book excerpt: Life on the planet depends on microbial activity. The recycling of carbon, nitrogen, sulphur, oxygen, phosphate and all the other elements that constitute living matter are continuously in flux: microorganisms participate in key steps in these processes and without them life would cease within a few short years. The comparatively recent advent of man-made chemicals has now challenged the environment: where degradation does not occur, accumulation must perforce take place. Surprisingly though, even the most recalcitrant of molecules are gradually broken down and very few materials are truly impervious to microbial attack. Microorganisms, by their rapid growth rates, have the most rapid turn-over of their DNA of all living cells. Consequently they can evolve altered genes and therefore produce novel enzymes for handling "foreign" compounds - the xenobiotics - in a manner not seen with such effect in other organisms. Evolution, with the production of micro-organisms able to degrade molecules hitherto intractable to breakdown, is therefore a continuing event. Now, through the agency of genetic manipulation, it is possible to accelerate this process of natural evolution in a very directed manner. The time-scale before a new microorganism emerges that can utilize a recalcitrant molecule has now been considerably shortened by the application of well-understood genetic principles into microbiology. However, before these principles can be successfully used, it is essential that we understand the mechanism by which molecules are degraded, otherwise we shall not know where best to direct these efforts.
Download or read book Chlorinated Insecticides written by G.T Brooks and published by CRC Press. This book was released on 2017-09-20 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This definitive and most detail work ever to have been published, devoted exclusively to the chemistry and biology of chlorinated insecticides, comes from the authoritative pen of a leading investigator in this field. It should serve for many years to come as the prime reference source both for instructional and research purposes, for it not only delineates that which is known about this valuable class of compounds, but also emphasises those important biological and ecological areas in which our knowledge is still much too sketchy and in which further investigation may be expected to uncover facts of great interest and wide applicability.

Download or read book Toxicology of Insecticides written by Fumio Matusmura and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most rewarding aspect of writing a book is receiving encouraging comments from one's colleagues, since one always wonders whether fair coverage was made of the work of others or whether some omissions were made. I feel very fortunate that many colleagues took the time to read the first edition of this book and chose to use it as a textbook in their teaching. During the past few years they have given me valuable suggestions by pointing out areas that needed to be added to improve the book. Toxicology is one of the fastest moving scientific fields. In the areas of insecticide toxicology many new advances have been made since this treatise first appeared. Therefore, it would not be easy to write even a review paper that would not be outdated by the time it was published. In revising this volume I have made a conscious effort to adhere to the basic principles which have been developed over the years. While I have retained the basic framework of the original book, advances that fundamentally change certain concepts or add a new horizon have been chosen for updating those fields where applicable. The main emphasis has been placed on the addition of new sections and new compounds developed since 1975. Since the first edition appeared, several books covering technical details in each group have been published. They are excellent encyclopedic resources in their chosen areas, and are listed in each section as recommended reading material.
Download or read book Toxicology of Insecticides written by Fumio Matsumura and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why are books written? Since I have read many works by my colleagues with admiration, this question has always intrigued me. Further, writing a book takes a good deal of time and effort, and I had imagined that I would never undertake such a demanding task. A few unexpected events and circumstances have changed my mind. The first was the pleasant experience of editing Environmental Toxicology of Pesticides with Drs. Mallory Boush and Tomomasa Misato. This fine symposium volume occasioned many interesting responses, including a suggestion to prepare a more complete treatise on the grounds that such "proceedings" volumes, by their very nature, do not satisfactorily offer a complete and coherent description of the field, but cater chiefly to specialists. I myself prefer single-authored books for basic understanding of a scientific field. The second circumstance leading to the present volume was the avail ability of teaching notes from my course on the toxicology of insecticides. As the need to cultivate environmental awareness has increased, there has been a parallel increase in the enrolments of such courses both here and in other major institutions. Yet no comprehensive and up-to-date text has been available. The third factor which facilitated the effort was an especially pleasant sabbatical in Hawaii, where the availability of the excellent Hamilton Library at the University of Hawaii considerably eased my task.

Download or read book Chemistry of Pesticides written by N. N. Melnikov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was originally published as a Russian edition in mid-1968. It represented the first single-volume discussion of chemical pest control and of the detailed chemistry.of all modern pesticide chemicals since D. E. H. Frear's classical book on this same subject, first published in 1942 (van No strand) with the latest (third) edition in 1955. Since 1955 many new pesti cide chemicals have achieved commercial status, and many of the older ones have been supplanted. There is no up-to-date equivalent of this present volume in the world literature, with the exception of the encyclopedic and largely biologically oriented two-volume work "Chemie der Pflanzenschutz und Schadlingsbekampfungsmittel" (R. Wegler, ed.) published by Springer Verlag in 1970. Professor Melnikov has updated the 1968 Russian edition, with emphasis on the primary Russian sources yet with excellent world wide coverage of the latest chemicals to approach field stature in modern chemical pest control, for the present translation."

Download or read book Management of Microbial Resources in the Environment written by Abdul Malik and published by Springer Science & Business Media. This book was released on 2013-02-26 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume details the exploration, collection, characterization, evaluation and conservation of microbes for sustainable utilization in the development of the global as well as national economies, e.g. in agriculture, ecosystems, environments, industry and medicine. Many research institutes and universities all over the world carry out microbiological and biotechnological research, which generates substantial genomic resources such as cDNA libraries, gene constructs, promoter regions, transgenes and more valuable assets for gene discovery and transgenic product development. This work provides up-to-date information on the management of microbial resources in the environment. It also covers the ecology of microorganisms in natural and engineered environments. In trying to understand microbial interactions it further focuses on genomic, metagenomic and molecular advances, as well as on microbial diversity and phylogeny; ecological studies of human, animal and plant microbiology and disease; microbial processes and interactions in the environment; and key technological advances. Though not intended to serve as an encyclopedic review of the subject, the various chapters investigate both theoretical and practical aspects and provide essential basic information for future research to support continued development.
