Biotechnology has vast potential for use in Agriculture, Forestry, Horticulture, Medicine, Food Industry, Chemical Industry, Pollution Control and Environment. (I) AGRICULTURE. The applications of biotechnology to agriculture are vast. The following activities will .
Of particular interest is the application of biotechnology to enable a global sustainable bioeconomy for the production of renewable chemicals, plastics and biofuels reducing energy consumption and creation of waste. This includes studies on the utilization of organic and inorganic ( bioleaching) waste streams and on resource conservation.
Biotechnology offers a `natural' way of addressing environmental problems, ranging from identification of biohazards to bioremediation techniques for industrial, agricultural and municipal effluents and residues. Biotechnology is also a crucial element in the paradigm of `sustainable development'.
Biomining Microorganisms' Molecular Aspects and Applications in Biotechnology and Bioremediation: /: The effective dissolution of metals is widely known with the help of microorganisms called bioleaching or biomining used for the extraction of metals from
Bioleaching technology in minerals processing John Neale Mintek, Biotechnology Division Private Bag X3015, Randburg, 2125, South Africa Bioleaching is a process that employs microorganisms to dissolve (leach) sulphide minerals. It finds application in the extraction of metals from their ores.
FACTORS AFFECTING BIOLEACHING IN THE PROCESSING OF NONMETALLICS IVETA ŠTYRIAKOVÁ Department of Biotechnology, Institute of Geotechnics of the Slovak Academy of Sciences, Watsonova 45, Košice, SK043 53, Slovak Republic (bacil) Abstract: Biotechnological treatment of nonmetallics is based on bacterial leaching of raw material and
Dec 30, 2013· Biotechnology Applications. The chapters have been authored by eminent scholars from India and abroad working on diverse disciplines related to Biotechnology. The book is an invaluable source of information on biosensors, microbial surfactants, enzyme immobilization, disease diagnosis, probiotics, protein biotechnology, bioleaching,...
Environmental Biotechnology: Theory and Application. The application of biologicallyengineered solutions to environmental problems has become far more readily acceptable and widely understood. However there remains some uncertainty amongst practitioners regarding how and where the microscopic, functional level fits into the macroscopic,...
Apr 12, 2016· Biotechnology. 31. is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional leaching using cyanide. Bioleaching is one of several applications used to recover copper, zinc, lead, arsenic, antimony, nickel, .
Biotechnology: What's in a name? April 10, 2008. By Associate Professor Dr Clem Kuek (Published in 'Campus Beyond', a weekly column written by Swinburne academics in the Borneo Post newspaper)
Bioleaching can change sediment structure, as well as create the potential to control water flow in aquifers and produce biomaterials of commercial value. Microbes, especially fungi, are useful as biofertilizers, by making nutrients more available to plants and increasing crop growth and yield. Microbes are useful in medicine as well.
Mar 24, 2016· In addition to biofuels, another important application of extremophiles and their enzymes can be found in the mining sector 40. This process, also known as bioleaching, is the removal of insoluble metal sulfides or oxides by using microorganisms 41. It is a safer and more environmentally friendly way to extract metals compared with traditional heap leaching, which involves the use of several .
Sep 04, 2016· Biohydrometallurgy is essentially the application of biotechnology to processing minerals [8,10]. Technically, the process is a branch of hydrometallurgy, but it involves the use of microorganisms to biooxidise sulphide minerals ore from lowgrade copper ore deposits . The bacterial metabolic processes lead to the metal extraction via biooxidation process.
Microbial Leaching (Bioleaching, Biomining) Microbial leaching is the process by which metals are dissolved from ore bearing rocks using microorganisms. For the last 10 centuries, microorganisms have assisted in the recovery of copper dissolved in drainage from water. Thus biomining has emerge as an important branch of biotechnology in recent years.

To identify the commercial application potential of bioleaching in Iranian copper industry, a research program was initiated. The objective of the main part of this program was to evaluate bacterial leaching processes for copper recovery from (i) high grade ores and flotation concentrates and (ii) low grade ores and flotation tailings.
