Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.…

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book brings together a number of comprehensive accounts of the mechanisms whereby microorganisms are able to degrade a wide variety of compounds. These compounds range from petroleum-derived materials, which continue to predominate in questions of environmental contamination and pollution, to the degradation of the major natural materials that microorganisms may encounter in all types of habitat. Both aerobic and anaerobic modes of attack are covered. The emphasis in all the chapters is upon the underlying biochemical pathways that microorganisms use: differences between bacteria, yeasts and moulds are highlighted whenever opportune and uses of microbial consortia for attack on the most recalcitrant molecules is also well documented. Activity of microorganisms in the soil, groundwater and marine environments are all dealt with here. The book will be of value and interest to all whose work brings them into direct or even indirect contact with the results of microbial degradations. The consequences of microbial degradations may be beneficial as well as deletrious: an advantage with some compounds, a decided disadvantage with others. The basis by which microorganisms achieve these attacks then provides the vital knowledge that will accelerate the former and, hopefully, retard the latter. For the first time the pathways of microbial degradations of all major classes of compounds are covered in a single volume. The diversity of microbial activities are clearly described and current advances in the applications of biochemistry, molecular biology, genetics, enzyme chemistry and engineering feature in almost every chapter.…
