Book excerpt: Excerpt from Examination of Soils for Organic Constituents, Especially Dihydroxystearic Acid There have been isolated from soil organic matter since this work was begun in these laboratories a large number of compounds 1 which are so varied in their composition, properties, and origin that they may be said to cover fairly well the principal classes of com pounds encountered in other lines of biochemistry, and, therefore, the knowledge in regard to the chemical relationship, origin, and pro cesses of change accumulated in such other lines can be directly applied to the understanding of the biochemical changes in soils and the constitution of soil organic matter.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Organic Constituents of Soils The soil is not simple, but complex. The soil properties and functions are likewise complex, not simple. All of the investigators preceding me in this symposium have emphasized to you by their papers how complex the subject is and how much remains to be done before a clear insight is Obtained, but they have also shown to you clearly that a well-trained army of scientists is at work on the prob lems connected with soil fertility, applying. Thereto all the principles of modern science. The Old view was simplicity itself; the soil was a mere trough in which the plant found its nourishment. But I can do no better than to let Liebig speak for himself. I quote from Letter XII of his Familiar Letters on Chemistry A field in which we cultivate the same plant for several successive years becomes barren for that plant in a period varying with the nature of the soil; in one field it will be three, in another seven, in a third twenty, in a fourth a hundred years. One field bears wheat and no peas; another beans and turnips but no tobacco; a third gives a plentiful crop of turnips but will not bear clover. What is the reason that a field loses its fertility for one plant, the same which at first flourished there? What is the reason one kind of plant succeeds in a field where another fails?

This book was released on 2018-09-09 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Certain Organic Constituents of Soils in Relation to Soil Fertility The work of isolating and studying the nature of such. Bodies is now in progress, but it is necessarily slow and difficult to accomplish. In the first place, the amount may be very small, and, secondly, the 'composition of the organic matter of the soil is undoubtedly very complex, being made up of many individual organic compounds. The absorptive power of the soil for organic bodies is so very great that the ordinary solvents, such as water, alcohol, chloroform, etc., take out but very minute amounts of organic material, .although this material may be quite soluble when not associated with the soil. The amounts of organic matter in ordinary soils is really. Appreciably large, the average content being as high as per cent for the soil and per cent for the subsoil, as found in thousands of sam ples from all parts of the United States, covering in all 237 types of soil. It Is obvious that this organic matter is of very complex com position, as its properties are quite different in soils from different localities. The amount of nitrogen also is considerable, as much as to per cent, and when we consider that only a small amount of this nitrogen is in the form of ammonium compounds or nitrate and that the larger amount is in organic form it is obvious that the problem Is a very complex one, but one of great agricultural importance.

Download or read book Approaches in Bioremediation written by Ram Prasad and published by Springer. This book was released on 2018-12-08 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioremediation refers to the clean‐up of pollution in soil, groundwater, surface water, and air using typically microbiological processes. It uses naturally occurring bacteria and fungi or plants to degrade, transform or detoxify hazardous substances to human health or the environment. For bioremediation to be effective, microorganisms must enzymatically attack the pollutants and convert them to harmless products. As bioremediation can be effective only where environmental conditions permit microbial growth and action, its application often involves the management of ecological factors to allow microbial growth and degradation to continue at a faster rate. Like other technologies, bioremediation has its limitations. Some contaminants, such as chlorinated organic or high aromatic hydrocarbons, are resistant to microbial attack. They are degraded either gradually or not at all, hence, it is not easy to envisage the rates of clean-up for bioremediation implementation. Bioremediation represents a field of great expansion due to the important development of new technologies. Among them, several decades on metagenomics expansion has led to the detection of autochthonous microbiota that plays a key role during transformation. Transcriptomic guides us to know the expression of key genes and proteomics allow the characterization of proteins that conduct specific reactions. In this book we show specific technologies applied in bioremediation of main interest for research in the field, with special attention on fungi, which have been poorly studied microorganisms. Finally, new approaches in the field, such as CRISPR-CAS9, are also discussed. Lastly, it introduces management strategies, such as bioremediation application for managing affected environment and bioremediation approaches. Examples of successful bioremediation applications are illustrated in radionuclide entrapment and retardation, soil stabilization and remediation of polycyclic aromatic hydrocarbons, phenols, plastics or fluorinated compounds. Other emerging bioremediation methods include electro bioremediation, microbe-availed phytoremediation, genetic recombinant technologies in enhancing plants in accumulation of inorganic metals, and metalloids as well as degradation of organic pollutants, protein-metabolic engineering to increase bioremediation efficiency, including nanotechnology applications are also discussed.
Download or read book Food Authentication written by Philip R. Ashurst and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue of food authenticity is not new. For centuries unscrupulous farmers and traders have attempted to 'extend', or othewise alter, their products to maximise revenues. In recent years the subject has reached new prominence and there even have been situations where food authenticity has featured as a newspaper headline in various countries. Food legislation covering the definition, and in some cases composition, of various commodities has been in place in developed countries for many years and paradoxically it is the legislative trend away from emphasis on composition and more on accurate and truthfullabeliing that has been one driving force for the authenticity issue. Another, and many would speculate as the more potent, driving force is the move towards fewer and larger supermarket chains in many countries. Such trading companies with their images of quality products, buying power and commercial standing, exercise considerable commercial power which has been claimed as a significant source of financial pressure on food prices and food commodity product quality. For whatever reason, recent food authenticity issues have become news and consumers, the media and enforcement authorities are showing more interest than ever before in the subject.

Download or read book Biological Toxins and Bioterrorism written by P. Gopalakrishnakone and published by Springer. This book was released on 2015-01-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological toxins are an important part of our world, a reality with which we need to cope, so in parallel with understanding their mechanisms of action and thereby improving our fundamental knowledge, there are successful efforts to utilize them as therapeutics against some debilitating human and animal diseases. In view of the complexity of different types of biotoxins and the broad range of toxin structure, physiology, utility, and countermeasures including regulatory issues, it was thus aimed to compile a book on biotoxins and bioweapons. This reference work in the Toxinology handbook series gathers together knowledge from around the globe about naturally inspired and manufactured biological weapons. The authors describe how they work; how authorities may detect their presence, prevent their use, and diagnose their impacts; and the means by which medical and paramedical professionals may treat victims. Also described are how they have been used to further our knowledge and what insights they have given us into evolutionary and physiological processes. Finally, it is also discussed how these toxins can be used as therapeutics and what the implications of such therapeutics are to their use as biothreat agents. This volume provides a reference accessible to scientists, educators, and medical experts alike with an interest in biotoxins, focusing on the major toxins used as bioweapons. Regulatory agencies will also benefit from the information provided in this book. Some in the intended audience may need to understand how they elicit their effects and how we can defend ourselves against them. Others may be interested in the sometimes colorful histories that surround this subset of biotoxins that can be and, in some cases, have been used as weapons.
