Teaming with Microbes by Wayne Lewis,Jeff Lowenfels Pdf
Healthy soil teems with life—not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms. Chemical fertilizers injure the microbial life that sustains healthy plants, and the soil becomes increasingly dependent on artificial, often toxic, substances. But there is an alternative: by strengthening the soil food web—the complex world of soil-dwelling organisms—gardeners can create a nurturing environment for plants. Teaming with Microbes extols the benefits of cultivating the soil food web. It clearly explains the activities and organisms that make up the web, and explains how gardeners can cultivate the life of the soil through the use of compost, mulches, and compost tea. With Jeff Lowenfels’ help, everyone—from devotees of organic gardening techniques to weekend gardeners who simply want to grow healthy, vigorous plants—can create rich, nurturing, living soil.

Microbes and Enzymes in Soil Health and Bioremediation by Ashok Kumar,Swati Sharma Pdf
Microbial enzymes play a vital role in maintaining soil health and removing pollutants from contaminated land. Soil microflora is closely associated with maintaining soil fertility, and the use of chemical pesticides, fertilizers and other volatile sprays in agriculture threatens the health ofthe microbial population in the soil. Every single particle of healthy soil contains millions of bacteria, which interact with the nutrients available, sustaining the nutrient cycle and making this microflora an essential component of life on earth. How do microbes help in the nutrient cycle? Either by intracellular digestion of macromolecules and converting these into smaller units in their metabolic pathways, or by secreting enzymes into the extracellular environment to facilitate the conversion of complex macromolecules into micro-molecules that can be easily absorbed by other living species. To meet demands for energy and food for the growing global population, it is important to protect agricultural land from contamination and maintain its productivity. Heavy metal ions from contaminated land canenter crops, fish or aquatic organismsvia contaminated water, and theseare then taken up by the human body, where they can accumulate and alter the normal microflora. The microbiological component of the soil is ahighly complex system and is still not fully understood. How do microbes survive in the changing physicochemical environment of soil?. This book helps readers understand the mechanism, various routes of microbialsoil remediation, the interactionsof different genera, and how microbial enzymes support the sustainable restoration of healthy soil.
Modern Soil Microbiology, Second Edition by Jan Dirk van Elsas,Janet K. Jansson,Jack T. Trevors Pdf
In the ten years since the publication of Modern Soil Microbiology, the study of soil microbiology has significantly changed, both in the understanding of the diversity and function of soil microbial communities and in research methods. Ideal for students in a variety of disciplines, this second edition provides a cutting-edge examination of a fascinating discipline that encompasses ecology, physiology, genetics, molecular biology, and biotechnology, and makes use of biochemical and biophysical approaches. The chapters cover topics ranging from the fundamental to the applied and describe the use of advanced methods that have provided a great thrust to the discipline of soil microbiology. Using the latest molecular analyses, they integrate principles of soil microbiology with novel insights into the physiology of soil microorganisms. The authors discuss the soil and rhizosphere as habitats for microorganisms, then go on to describe the different microbial groups, their adaptive responses, and their respective processes in interactive and functional terms. The book highlights a range of applied aspects of soil microbiology, including the nature of disease-suppressive soils, the use of biological control agents, biopesticides and bioremediation agents, and the need for correct statistics and experimentation in the analyses of the data obtained from soil systems.
Elucidating Microbial Processes in Soils and Sediments: Microscale Measurements and Modeling, 2nd Edition by Philippe C. Baveye,Wilfred Otten,Alexandra Kravchenko Pdf
Half a century ago, soil microbiologists reached the conclusion that a full understanding of the growth and activity of microorganisms in soils and sediments would require quantitative observations at spatial scales as near as possible to the size of the organisms themselves. Back then, this type of observation was not feasible at all, unfortunately. The development of electron microscopes in the 60s and 70s provided qualitative insight into microscopic parameters that controlled the activity of bacteria, archaea, and fungi in pore spaces, but produced no quantitative information. It is only with the technological advances in X-ray computed micro-tomography (μCT), first at synchrotron facilities in the 90s, then with commercial table-top scanners in the early 2000s, that quantitative, micrometric data on the geometry of the pore space has become available. In the last decade, different methods have also been developed to measure the spatial distribution of microorganisms at fine resolution in thin sections, as well as to map the composition of organic soil constituents or the nature of nitrogenous compounds at micrometric or even nanometric scales. Finally, a number of computational approaches have been adopted successfully to model mathematically the various physico-chemical processes occurring within pores, which affect the growth and activity of microorganisms. After these novel techniques became available, an initial stage in the research has consisted of identifying and resolving the problems associated with their use to elucidate microbial processes in heterogeneous soils and sediments. Significant progress has been achieved in this respect, for example in the development of objective (operator-independent), local segmentation techniques adapted for X-ray μCT images, in terms of improvements of hybridisation (FISH) technologies to locate bacterial and archaeal cells in soil thin sections, or in the in elaboration of statistical tools to interpolate 2-D measurements to produce 3-D data. All of this progress enables us to now enter with confidence into a second stage of the research, where different techniques will be combined to apprehend more completely the characteristics of microhabitats in terrestrial systems. A number of research groups around the world are trying to quantify the physical and (bio)chemical features of these microhabitats, as well as to describe as thoroughly as possible the composition and biodiversity of microbial populations they contain. Within the next few years, increasing focus will be placed on this integration of techniques, and progress in this respect will likely be fueled very significantly by the development of an array of new techniques, e.g., single-cell metabolomics or X-rays produced by plasma wave accelerators, which offer great promise for the research on soils and sediments.
