BIOREMEDATION
BIOREMEDIATION
INTRODUCTION:-
The process of bioremediation was reportedly devised by George M Robinson in the 1960 during experimentation with dirty jars and the introduction of microbes this was however not applied until the 1972 clean out of the fuel holding tanks on the RMS queen mary.
Science 1972 bioremediation has become greater developed as a means of cleaning up spills of gasoline diesel , heavy metals and other easily degraded petroleum products (National Research Council 1993).
Bioremediation refers to the use of microorganisms to degrade contaminants that pose environmental and especially human risks. Due to its safety and convenience it has became an accepted remedy for cleaning polluted soil and water.
A widely used approach to bioremediation involves stimulating a group of organisms in order to shift the microbial ecology towards the desired process. This term is known as biostimulation.
Biostimulation can be achieved through changes in pH, moisture, aeration or nutrient addition.
DEFINATION:-
Biodegradation:-
Biodegradation or biological degradation is the phenomenon of biological transformation of organic compounds by living organisms (Microbes).
It usually involves the conversion of complex organic molecules to simple and mostly non toxic ones.
Bioremediation:-
‘Bio’ means living organisms and ‘remediate’ means to solve a problem. “Bio-remediate” means to use biological organisms to solve.
Bioremediation can be defined as “the use of living organisms (Primary microorganisms) to degrade through waste treatment”.
The environmental pollution i.e. toxic waste formed in soil, water, air.
The microbes act as sc avenger’s bioremediation.
The removal of organic wastes by microbes for environmental cleanup is the goal of bioremediation.
The other names used for bioremediation are biotreatment, bioclamation and bio-restoration.
Xenobiotics Compounds:-
‘Xenos’ means foreign.
These are manmade chemical that are present in the

    Phytoextraction (or phytoaccumulation) uses plants or algae to remove contaminants from soils, sediments or water into harvestable plant biomass (organisms that take larger-than-normal amounts of contaminants from the soil are called hyperaccumulators). Phytoextraction has been growing rapidly in popularity worldwide for the last twenty years or so. In general, this process has been tried more often for extracting heavy metals than for organics. At the time of disposal, contaminants are typically concentrated in the much smaller volume of the plant matter than in the initially contaminated soil or sediment. 'Mining with plants', or phytomining, is also being experimented with. The plants absorb contaminants through the root system and store them in the root biomass and/or transport them up into the stems and/or leaves. A living plant may continue to absorb contaminants until it is harvested. After harvest, a lower level of the contaminant will remain in the soil, so the growth/harvest cycle must usually be repeated through several crops to achieve a significant cleanup. After the process, the cleaned soil can support other vegetation.…

    Bacterial transformation is the process of bacteria taking in and expressing exogenous DNA. This has led to many other discoveries. In order for bacterial transformation to occur the bacteria must be in a certain physical state to be able to take in DNA. This is called competency and it allows the cell membrane to be permeable so DNA can pass through. Currently researchers are studying the transformation of E. Coli, which was used in this experiment. It is not normally in a state of competency so the researchers treat it with chloride salts and heat shocking to induce competency. (EDVOTEK, 5-6)…

    Biological polluters. When these words come to mind we think of negative factors damaging our environment, but what exactly are biological polluters. Biological pollution is the terms used for the pollution to the environment one organism produces when it is transported to a nonnative area. Biopollution is very common in South Florida. The diversity of cultures has cause a high peak in the amount of invasive species found in South Florida. The native plants and animals suffer greatly from biopollution.…

    Perhaps the most contentious aspect of desalinization, however, is how to dispose of the highly concentrated salt brine left over from the plant’s water cleansing. Every hundred gallons of desalinated seawater yields fifteen to fifty gallons of drinking water (depending on the process, and the water to begin with), and fifty to eighty gallons of brine. Where, the highly concentrated brine is flushed back into the sea. It can destroy aquatic species, particularly those in the egg or immature phase of development. (Prud’homme336).…

    Bacteria are very important in our society and the environment because they benefit us, as well as many other species. Some of the ways they benefit humans is through the production of certain foods. I.e cheese, yogurt, vinegar, wine, sour cream, etc. Bacteria can also be used in industry to clean up petroleum spills, to remove harmful waste products from the water, sewage treatment plants, and to synthesize drugs and chemicals. Bacteria feed on dying material and convert it back into basic substances. This process of decomposition is as significant as photosynthesis, for without it food chains would cease, and fallen trees, leaves, and other refuse would simply pile up. Bacteria also strongly influence the movement of key elements, such as sulfur, iron, phosphorus, and carbon, around the globe. The weathering of rocks, which releases elements back into life systems for use, is substantially enhanced by the breakdown processes…

    Bioaccumulation: If a chemical in the environment breaks down slowly or does not break down at all, plants may take it up and animals may take it in when they breathe. If they do not excrete or egest it, it will accumulate in their bodies over time. Its concentration will therefore build up until eventually it may be high enough to kill the organism.…

    Biomagnification is the accumulation of substances, especially many chlorinated hydrocarbons that are used as pesticides. Common chlorinated hydrocarbons include DDT, dieldrin, and PCBs. These chemicals are insoluble in water, but highly soluble in organic solvents like animal fats and plant oils. Due to their insolubility, they are persistent in the environment and cannot be broken down by any natural processes.…
