Waste Management and Modern Environmental Biotechnology
In today’s modern society were industrial revolution is on its peak, there is a change in the way we live in this world. Due to industrial development mankind started to live in a dense population and this further gave the way to develop city which have all the requirements and decencies required to live. Due to industries and increase in population, waste generation also increased. Chemical waste, industrial waste, hazardous waste, radioactive is now present in environment. Those waste formed by nature being take care by nature itself and balance is maintained, like decaying, decomposing which also becomes food for scavengers. But the real problem comes in picture when industrial waste is much hazardous and lethal. The threat is to all aquatic animals, agricultural, other farm animals and humans but the totality of this effect is on our mother earth and the nature in which all we live.
Now a day’s various waste management projects are being initiated by the many countries even lot of funding being raised for the same, the ultimate aim is to save our planet earth and to make it green & natural. Lot of regulations is being developed and is strictly followed; all industries now use waste management and water management systems in their premises. This includes effluent treatment plants, bio-hazard waste management’s, Chemical waste management’s, controlled hazardous waste generation.
Various microbes are developed with genetic engineering which have special features and help in eliminating the waste. One such good example is treatment of Uranium contaminated sites with GMO-microbes which has shown tremendous results. Now a day’s Mercury and other heavy metals are being extracted from the waste by using special strains of microbes. Various methods as such activated sludge, tricking filters, oxidation ponds; membrane bioreactors, etc are used successfully to treat the municipal and industrial waste water. Solid and liquid waste containing high amount of organic waste are now used to obtained methane by using microbes and this gas is used domestically and called as bio-gas .
Let us all, think and act together to make our planet earth green and free from non-biodegradable wastes after all it’s our own mother earth & the only known planet to have life !
Such a excellent information. The industry of biotechnology has grew up during the past several years covering, in addition to inherited technological innovation, the application of modern microbiological ideas to the new and rapidly creating field of ecological protection. The features between microbiology and environmental incident provides a indicates of understanding procedures leading to pollution occurrence, recognition, tracking, avoidance and control. Biotechnology offers both traditional and impressive solutions to problems associated with water pollution, contaminants of the ground, the weather, and the stratosphere. Environmental biotechnology techniques, or bio processes, are now popular in the recognition and treatment of waste materials, waste waters and other environmental pollutants.
In our Environmental Biotechnology specialisation in the Bachelor of Biomolecular Science Advanced at the Gold Coast campus, you will learn how the developments in the biomolecular sciences are being applied to protect the environment — how molecular and biological agents are being used for the control of pests, in bioremediation and waste management and how modern molecular techniques are being used in diagnostics for monitoring the health of the environment.
The Deinococcus radiodurans bacterium is very fascinating. Its name means “strange berry that resists radiation”, and it is a very fitting name, as D. radiodurans can withstand up to 5,000 GYs of radiation. Humans can only survive about 4 GYs of radiation. D. radiodurans is not the only organism that can resist such high doses of radiation. Other bacteria, some archaea, and the invertebrate animal the tardigrade, can all withstand extremely high levels of radiation. High doses of radiation cause a large number of double-stranded breaks in the DNA. D. radiodurans has multiple copies of its genome, so even if one gene is damaged, there is a back-up available. D. radiodurans is also able to segregate damaged DNA from other parts of the genome for repair. It is not known why D. radiodurans would have evolved a mechanism to survive such extreme radiation. Some evidence, however, suggests that the mechanism was meant to help protect the bacterium from severe dehydration.

Like many things in our environment, D. radiodurans has been used by humans. The D. radiodurans bacterium can be engineered to digest heavy metals and solvents, and is able to do so even in highly radioactive areas, making a helpful agent in bioremediation. D. radiodurans has even been considered as a means to store information that can be passed on in case of a nuclear catastrophe. Scientists were successfully able to have D. radiodurans store the information for the song “It’s a Small World.” However, each strain of bacteria could only hold a small amount of information. Many strains were engineered, and maintained separately. This means that D. radiodurans may not be a very practical method of storing information.
