Heavy Metal Resistance of Microorganisms
By:
Shivika Bhatnagar
Most of the heavy metals such as cadmium, vanadium, manganese, lead, arsenic, iron, mercury, zinc, nickel, chromium, copper, antimony etc. are toxic to biological systems, not only due to their inert nature but also due to their persistence and long run cumulative effects. The occurrence of Itai-itai disease due to cadmium, minamata disease due to arsenic are some of the examples of heavy metal pollution.Fungi, bacteria, actinomycetes, algae etc. are the major microorganisms reported to tolerate heavy metals which universally occur in diverse ecosystems.

Introduction and Applications of Bioremediation
By:
Syed Amir Manzoor
The article focuses on the key concepts associated with bioremediation. Bioremediation comes from two words bios means life and remediate means to decipher an issue. The degradation of noxious waste from the environment using microorganisms is called as bioremediation. Microorganisms like bacteria, fungi, algae etc take part in bioremediation.

Microbial Remediation of Waste From Paper Making and Paper Recycling Industries
By:
Sonali Bhawsar
Bioremediated solid and water waste from paper industries have potential to be utilized as material for land filling and fertilizers respectively. Fertilizer value of bioremediated waste is in fact upgraded by nitrogen fixing activities of bacterial flora indigenous to waste water.

Bioextraction Mechanisms of Metals From Their Ores
By:
Sonali Bhawsar
Metal leaching by bacteria is ecofriendly metallurgical process. Only these bacteria are able to extract all the metal present in the respective ore at very low concentration or in presence of other impurities. Comparatively, traditional physicochemical extractions processes like heap leaching, roast smelting and molal extraction can be utilized in mining industries only when ore consist of sufficient concentration of metal. This is very important consideration, when the richer mineral deposits worldwide are being exploited by abiotic leaching processes. One day, such exploitation will sure result in formation of low grade ores which would have depleted mineral content. That time no option other than bioleaching would be available for extraction of metals and it will be an important process for the recovery of minerals from their ores.

Bioremediation by Cold Tolerant Microbes
By:
Shekhar C Bisht
Bioremediation is a process to accelerate the natural biodegradation rates through the optimization of limiting environmental conditions and is an ecologically and economically effective method. Low-temperature biodegradation of organic contaminants in cold ecosystems is a result of the degradation capacity of the indigenous psychrophilic microbial population.

Phytoremediation - Use of green plants to remove pollutants
By:
Suresh Kaushik
The major challenge facing society in the twenty-first centaury is to feed and provide for increasing numbers of people while protecting human health and the environment. Over the last centaury, increasingly wide spread heavy metal pollution and organic contaminants have caused many areas to become non-arable and hazardous for both wildlife and human populations. Industrial waste products account for most heavy metals pollution, although sewage and household waste also introduce substantial levels of toxic metals into the environment. Contaminated soils and waters pose a major environmental human problem. Physical, chemical and biological processes are already being used to remediate contaminated soil, but these techniques can grossly disrupt the polluted site and are expensive. This problem may be solved by the emerging phytoremediation technology that employs the use of higher plants for the cleanup of contaminated environments.

Bioremediation - A Weapon to Tackle Oil Spills
By:
Pournami Gouthaman
Bioremediation for oil spill cleanup: The release of petroleum hydrocarbons into the environment, especially into oceans can affect the marine ecosystem, birds and human. The action of naturally occurring oil degrading microbes are slow. Bioremediation is the process of using microbes to clean up waste material or pollutants. The addition of exogenous microbes or stimulating indigenous oil eaters can speed up the cleaning up process.

Biological Degradation of Xenobiotics
By:
Shikha Sharma
Xenobiotics are man-made chemical compounds that are very difficult to degrade. These compounds are made by synthetic organic chemicals and are stranger to the biosphere. They accumulate in the environment and cause harmful effects on the living system. Xenobiotics include chemically synthesized compounds such as pesticides, polyethylene, polystyrene & PVC.

Biotechnology and Environment Protection
By:
Nidhi Uppangala
Environment has been contaminated with non biodegradable compounds due to the revolution in science and technology. Most common contaminates found in the environment are commercial hydrocarbons, Organo-halogenated compounds like trichloroethylene, tetrachloroethane and much more. All these environmental contaminants can be degraded by using a biotechnology technique known as bioremediation.
