Essay On Bioremediation

1408 Words6 Pages

bioremediation is caused by the activities of anaerobic or aerobic heterotrophic microorganisms. Microbial activity is affected by a number of physico-chemical environmental parameters. The factors that have direct affect on bioremediation are nutrients energy sources (electron donors), temperature,electron acceptors, , pH, and restrictive substrates . One of the main difference between vadose zone soils, surface soils, and groundwater sediments is the structure and type of organic material. Surface soils, which generally get a lot of organic material from plants, will have more organic matter content. The high organic matter content is related to higher number of microbes and bigger variety of microbial populations. The organic matter acts as a depository of …show more content…

Cleaning up toxic waste is not easy .it usually requires time and lot of money.bioremediation is cost effective and environmental friendly.

3.5 Disadvantages Of Bioremediation

Bioremediation, seems to be blessing the modern day environmental conditionds but its not without flaws and drawbacks.
1. bioremediation is not an option for recalcitrant pollutants .it can degrade only those pollutants that atre easily biodegradable.
2. sometimes cleavage products are formed during bioremediation that are more toxic than parent pollutant.
3. High specificity of bioprocesess can become a problem.For effective biodegradation capable microbe populations,otimumgrowth conditions,suitable level of contaminants and nutrients is required.all this is hard to manage.
4. extrapolation from pilotscale or bench scale to full scale field operations can become a problem. 5. bioremediation is hard to carry out in an environment where mictures of pollutants are unevenly distributed within environment.So research in that area is need of the day.
6. polluting compounds may be present as liquids, solids, and gases.
7. Compared to other treatment options like incineration or removal of soil,bioremediation can take

  • Unknown Microbiology Essay

    517 Words  | 3 Pages

    Being able to identify unknown microbes from systematic testing is what makes the field of microbiology so important, especially in infectious disease control. Using the testing procedure laid out by the microbiology field we are able to identify unknown bacteria present in our everyday lives, and along the way learn a lot about their characteristics that separate them from other types of bacteria. Being able to do this is vital in order for us to understand why microbes are present in certain places, how they are able to grow and what restricts their growth, that way they can be combatted if necessary. These techniques for determining unknowns are also important for isolating and testing infectious disease microbes in order to prevent spreading. Another important aspect of being able to identify unknown microbes is the

    Since the beginning of mankind, there have been many examples of humans developing both positive and negative relationships with the environment. From early Native Americans preciously cultivating and restoring their natural surroundings, to large manufacturing conglomerates of the modern age polluting air and water without regard, the interaction between humans and their environment has been both productive and destructive in various ways. By evaluating that it is much more important for a developing civilization/nation to conserve and protect its resources rather than fully develop them, we can completely understand the unique impacts that the human race has had on the environment, and how significant the negative gaffes and consequently,

South Africa is known around the world for being one of the most diverse marine environment in the world, with 83% of the known fish families residing in South Africa (Van der Elst, 2007). There are also many marine species that are endemic to South Africa, which means they are only found in South Africa.

  • Pollution Essay: The Effects Of Climate Change Toward The Environment

    1719 Words  | 7 Pages

    One of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.

  • Fossil Fuels Pros And Cons

    1281 Words  | 6 Pages

    Energy plays a vital role in the modern human community as we power our computers, household utilities and many other important inventions. As the population of the world grows, our fossil fuel reserves are depleting quicker. Fossil fuels such as petroleum, coal and natural gas accounted for 81.5 percent of global primary energy consumption in 2015. The burning of fossil fuels have greatly contributed to global warming, however if we were to ultimately eliminate fossil fuels from energy sources, the production of energy will undoubtedly fall behind the demand. The solution proposed is to reduce the demand for fossil fuels by replacing some with a more sustainable and renewable alternative- biofuels.
