Download or read book Biomining written by Douglas E. Rawlings and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomining is the use of microorganisms in the recovery of metals from ores. 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.

Download or read book The microbial sulfur cycle written by Martin G. Klotz and published by Frontiers E-books. This book was released on 2011-12-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulfur is the tenth most abundant element in the universe and the sixth most abundant element in microbial biomass. By virtue of its chemical properties, particularly the wide range of stable redox states, sulfur plays a critical role in central biochemistry as a structural element, redox center, and carbon carrier. In addition, redox reactions involving reduced and oxidized inorganic sulfur compounds can be utilized by microbes for the generation and conservation of biochemical energy. Microbial transformation of both inorganic and organic sulfur compounds has had a profound effect on the properties of the biosphere and continues to affect geochemistry today. For these reasons, we present here a collection of articles from the leading edge of the field of sulfur microbiology, focusing on reactions and compounds of geochemical significance.

Download or read book Microorganisms in Polar Regions Understanding Their Survival Strategies for a Sustainable Future written by Prashant Kumar Singh and published by Frontiers Media SA. This book was released on 2024-07-02 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific research on cold-adapted microorganisms (specifically polar microbes) is of great interest, since Arctic and Antarctic regions harbor diverse and active populations of microorganisms. However, these microorganisms are subject to impacts of environmental perturbations. For example, climate change will modulate the distribution and activity of many cyanobacteria and algal species in polar environments that contribute significantly to global carbon fixation and oxygen production. Moreover, many microorganisms that have remained frozen for thousands of years can revive their metabolic activity and re-join the modern microbial community. For survival in freezing environments, polar microorganisms have established specific regulatory mechanisms which are now being challenged by new, rapidly changing environmental conditions. Remarkable progress has been made to uncover microbial adaptation to anthropogenic activities such as high irradiance, nutritional deprivation, UV-B radiation, heat, cold, desiccation, and heavy metals. Studies have enabled a basic understanding of gene regulatory pathways for morphological, physiological, metabolic, and genetic adaptations to various environmental stresses. To further elucidate physiological adaptation mechanisms and molecular diversity in polar regions, this Research Topic is focused on microbes in polar regions, looking at their biodiversity, ecological adaptations, the impact of climate change on their lifestyles, and biotechnological application of microbes for a sustainable future.
Download or read book The microbial ferrous wheel iron cycling in terrestrial freshwater and marine environments written by David Emerson and published by Frontiers E-books. This book was released on with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 15 years, there has been steady growth in work relating to the microbial iron cycle. It is now well established that in anaerobic environments coupling of organic matter utilization to Fe reduction is a major pathway for anaerobic respiration. In iron-rich circumneutral environments that exist at oxic-anoxic boundaries, significant progress has been made in demonstrating that unique groups of microbes can grow either aerobically or anaerobically using Fe as a primary energy source. Likewise, in high iron acidic environments, progress has been made in the study of communities of microbes that oxidize iron, and in understanding the details of how certain of these organisms gain energy from Fe-oxidation. On the iron scarcity side, it is now appreciated that in large areas of the open ocean Fe is a key limiting nutrient; thus, a great deal of research is going into understanding the strategies microbial cells, principally phytoplankton, use to acquire iron, and how the iron cycle may impact other nutrient cycles. Finally, due to its abundance, iron has played an important role in the evolution of Earth’s primary biogeochemical cycles through time. The aim of this Research Topic is to gather contributions from scientists working in diverse disciplines who have common interests in iron cycling at the process level, and at the organismal level, both from the perspective of Fe as an energy source, or as a limiting nutrient for primary productivity in the ocean. The range of disciplines may include: geomicrobiologists, microbial ecologists, microbial physiologists, biological oceanographers, and biogeochemists. Articles can be original research, techniques, reviews, or synthesis papers. An overarching goal is to demonstrate the environmental breadth of the iron cycle, and foster understanding between different scientific communities who may not always be aware of one another’s work.
