Bioremediation is the process of using microbial systems to restore the environment to a healthy state. Certain microorganisms can survive in metal rich environments where they can then leach metallic cations for use in the cell. These microbes can be used to remove metals from the soil or water.
Human microbiome, the full array of microorganisms (the microbiota) that live on and in humans and, more specifically, the collection of microbial genomes that contribute to the broader genetic portrait, or metagenome, of a human.The genomes that constitute the human microbiome represent a remarkably diverse array of microorganisms that includes bacteria, archaea (primitive single-celled
Responsible mining is a new catchword of our times. However, in practice, there seem to be many barriers that hinder the successful implementation of the concept. This is especially true for countries with high urbanization speed, and it is even true for one-party states where its implementation could, in general, be taken for granted as soon as the central government has taken respective

The role of the heterotrophic microorganisms in the leaching process is largely undetermined. Thiobacilli that attack some sulfide minerals and certain soluble sulfur compounds under neutral conditions (that is, neither acidic nor alkaline) are often found in sulfide ore deposits and in other habitats where sulfur is
Harnessing microbes to do mining work is called biomining, or sometimes bioextraction or bioleaching. The strategy has been most extensively studied for copper and gold: Colorado-based mining

2. ROLE OF MICOORGANISMS IN MINING 2.1. Role of Microorganisms in ARD Production It has been reported that a number of acidofilic or acid-tolerant bacteria namely Thiobacillus, Leptospirillum, Sulfolobus, Sulfobacillus and Metallogenium are associated with the mediation of acid generation from sulphide minerals at pH levels below 4.
Oct 01, 2019· These natural capacities can be exploited for the bioremediation of mine impacted sites. Microorganisms also play a key role in phytostabilisation, either indirectly by promoting plant growth or directly through metals and metalloids mobilization or immobilization in soils. Thus, microorganisms are important actors of mining sites remediation.
The role of microorganisms in the generation of ARD and their role in the methods used for prevention, control and treatment are discussed in this paper. Benefits, limitations and design criteria for passive biological processes are presented using examples of passive and biological treatment processes that have been developed recently and
Nov 01, 1971· The maintenance of water-stability of soil aggregates bound by different chemicalbinding agents produced in situ by pure cultures of microorganisms and by an indigenous soil microflora was assessed by wet-sieve analysis.. Seven fungi, six streptomycetes, and five bacteria produced binding materials in artificial aggregates of Miami silt loam amended with sucrose.

Single-celled microorganisms were the first forms of life to develop on Earth, approximately 3–4 billion years ago. Further evolution was slow, and for about 3 billion years in the Precambrian eon, (much of the history of life on Earth), all organisms were microorganisms. Bacteria, algae and fungi have been identified in amber that is 220 million years old, which shows that the morphology of
Oct 27, 2018· The critical role of desorption for the mineralization of P org is receiving increasing attention (Giaveno et al. 2010). Pseudomonas species are among the most frequently studied P-solubilizing bacteria, but also species of Burkholderia, Enterobacter, Pantoea, Bacillus solubilize P (Jorquera et al. 2008).
Microorganisms play a major role in eliminating such pollutants from the environment. Bioremediation of Soil. Soil is a major reservoir of microorganisms with each gram containing about one billion microbes. Microbes are used for bioremediation in situ of contaminated soil. Microorganisms that can remove contaminants from the environment are
Microorganisms have a prominent role in the production of acid.Dugan 1975 reported that their involvement occurs in four different ways 1.The increased production of acid via the metabolic activity of the acidophilic thiobacillus bacteria.2.The inhibitory influence of sulphuric acid on the organisms normally present in receiving streams.3.
Abstract. A soil aggregate has been defined as “a naturally occurring cluster or group of soil particles in which the forces holding the particles together are much stronger than the forces between adjacent aggregates” (Martin et al., 1955).The terms soil structure and soil aggregation are often used synonymously, but soil aggregates are the basic units of soil structure, rather than the
Jun 20, 2017· The wealth of biodiversity below ground is vast and unappreciated: millions of microorganisms live and reproduce in a few grams of topsoil and these organisms are critical to soil health and fertility. Soil biological fertility is, however, the least well-understood soil fertility component. Soil microorganisms also play essential roles in the nutrient cycles that are fundamental to life on

Thus, microorganisms are important actors of mining sites remediation.
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks

By Jennifer Stearns, Michael Surette . The question of why to study microbiology is a good one — the impacts of microorganisms on your life may not be immediately obvious. But the truth is, microorganisms not only have a huge impact but are literally everywhere, covering all the surfaces of your body and in every natural and urban habitat.
