DOWNLOAD EBOOK →Bioweathering is the dissolution of rocks and mineral substrates carried out by microorganisms along with mechanical and chemical processes. The application of bacteria in biomining is a biotechnological approach for the extraction and recovery of metals from ores. Microbes interact with minerals as a strategy to colonize and exploit habitats where the environmental parameters disadvantage other microorganisms and they demonstrate the capacity to scavenge critical elements with low bioavailability, such as iron and phosphorus. There is an ongoing need to improve soil fertility and crop production, particularly in dry places, to remediate toxic soils, and clean stone artworks and structures. A more complete understanding of the ecology of mineral weathering processes mediated by the microbiome may provide a significant opportunity for researchers to develop novel solutions to developing challenges in agriculture, the environment, and industry.

Among the presentations were updated solutions to enhance P-uptake by plants, bioremediation potential in the rehabilitation of ecosystems, taxonomic characterization interactions with mycorrizae, the physiological and molecular basis of PSM, and more.

DOWNLOAD EBOOK →Microbiology for Minerals, Metals, Materials and the Environment links chemical, metallurgical, and other metal inherent systems with microbes, and analyzes the interdependence between them. Specifically intended to underscore the importance of microbes in environmental remediation in the mining industries, this text offers a basic and conceptual understanding of the role of microbes, and provides an extensive exploration of microbiology and metals. Each chapter is written by experts from research, industry and academia. The authors expand on the whole scale of microbiology applications relevant to minerals, metal, material, and environment. They elicit the applications of microbes for metal extraction (including mechanisms and methods) from primary ores/minerals and mining wastes, biomining and related concepts of microbial diversity and various operations, and molecular biology of microbes involved in such systems (extremophiles). They also address in detail biohydrometallurgy, biomineralisation, bioleaching, biobeneficiation, biosynthesis, and bioremediation and other related areas. This book: Includes bacterial leaching, hybrid leaching, and biosynthesis related to different metals Covers recent developments in alternative procedures with the use of extremophiles and leaching bacteria Explains the imperative importance of bacteria in minerals and metals sector Addresses microbial interventions for waste cleanup and upgradation of minerals Compares existing processes with the new ones to elicit their importance Provides case studies on all respective topics by eminent researchers A resource for researchers, graduate students, and industry professionals involved in chemical/mining/metallurgical engineering/environmental science/microbiology, Microbiology for Minerals, Metals, Materials and the Environment skillfully explains the symbiotic relationship between microbiology and minerals-metals-materials, and utilizes experts from across the globe.

During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the water-insoluble sulfide to the soluble sulfate forms. Although gold is inert to microbial action, microbes can also be used in gold recovery from certain types of ores because as they oxidize the ore, they open up its structure, thereby allowing a gold-solubilizing agent such as cyanide to penetrate the ore. The book describes several industrial bioleaching and biooxidation processes as well as the underlying theory and biology of the microbes involved.

In order to meet this challenge, environmentally unfriendly agroch- icals have played a key role in the green revolution and are even today commonly recommended to circumvent nutrient de?ciencies of the soils. The use of ag- chemicals is, though, a major factor for improvement of plant production; it causes a profound deteriorating effect on soil health (soil fertility) and in turn negatively affects the productivity and sustainability of crops. Concern over disturbance to the microbial diversity and consequently soil fertility (as these microbes are involved in biogeochemical processes), as well as economic constraints, have prompted fun- mental and applied research to look for new agro-biotechnologies that can ensure competitive yields by providing suf?ciently not only essential nutrients to the plants but also help to protect the health of soils by mitigating the toxic effects of certain pollutants. In this regard, the role of naturally abundant yet functionally fully unexplored microorganisms such as biofertilizers assume a special signi?cance in the context of supplementing plant nutrients, cost and environmental impact under both conventional practices and derelict environments. Therefore, current devel- ments in sustainability involve a rational exploitation of soil microbial communities and the use of inexpensive, though less bio-available, sources of plant nutrients, which may be made available to plants by microbially-mediated processes.

DOWNLOAD EBOOK →Microbes and their biosynthetic capabilities have been invaluable in finding solutions for several intractable problems mankind has encountered in maintaining the quality of the environment. They have, for example, been used to positive effect in human and animal health, genetic engineering, environmental protection, and municipal and industrial waste treatment. Microorganisms have enabled feasible and cost-effective responses which would have been impossible via straightforward chemical or physical engineering methods. Microbial technologies have of late been applied to a range of environmental problems, with considerable success. This survey of recent scientific progress in usefully applying microbes to both environmental management and biotechnology is informed by acknowledgement of the polluting effects on the world around us of soil erosion, the unwanted migration of sediments, chemical fertilizers and pesticides, and the improper treatment of human and animal wastes. These harmful phenomena have resulted in serious environmental and social problems around the world, problems which require us to look for solutions elsewhere than in established physical and chemical technologies. Often the answer lies in hybrid applications in which microbial methods are combined with physical and chemical ones. When we remember that these highly effective microorganisms, cultured for a variety of applications, are but a tiny fraction of those to be found in the world around us, we realize the vastness of the untapped and beneficial potential of microorganisms. At present, comprehending the diversity of hitherto uncultured microbes involves the application of metagenomics, with several novel microbial species having been discovered using culture-independent approaches. Edited by recognized leaders in the field, this penetrating assessment of our progress to date in deploying microorganisms to the advantage of environmental management and biotechnology will be widely welcomed.

DOWNLOAD EBOOK →This book explains how microorganisms play a pivotal role in the formation of biominerals, including carbonates, silicate minerals and oxides. As readers will learn, these minerals may be produced either intracellularly or extracellularly in order to sustain microbial life. Experienced scientists from the field show that some of these biominerals can be produced in an active form, which involves direct enzymatic intervention to form precipitates. In addition, passive mineral formation can be mediated by the presence of dead cells. Readers from Microbiology and Biochemistry will appreciate the thorough coverage on various types of microbial mineral formation and their roles in microbial domains. Furthermore, they will benefit from the authors’ first-hand knowledge regarding common techniques for studying biomineral-producing microorganisms, factors affecting biomineralization, and the use of this process in biotechnological applications.
