ABSTRACT Biological代写

Bioremediation is a biotechnology branch that involves living organisms such as microbes and bacteria in the removal of pollutants, chemicals, and toxins from the environment. It is a valuable measure to remove toxins from the soil and water, especially in accidents of the oil spill, and to clean up contaminated groundwater. Bioremediation is done in two situations: contamination and away from the site. It depends on stimulating specific microbes that utilize pollutants like pesticides, oil, and solvents as their food source. These microbes decontaminate the environment by converting pollutants into harmless gasses and water.

INTRODUCTION Biological代写

For the process of bioremediation to become effective, there should be a combination of the right temperature, nutrients, and foods. The absence or delay of any of these requirements leads to delayed removal of pollutants, and sometimes, the entire process may fail. When dealing with unfavorable conditions for bioremediation, the introduction of amendments such as molasses, vegetable oil, or air improves the conditions for action by microbes, thereby speeding up the process.

Bioremediation is carried out in two stages depending on the climate of the area under clean up. In situ cleanup is done when the weather is favorable for microbe action. In situ approach is usually cheaper than the ex-situ method since ex-situ involved extracting the contaminated materials to areas suitable for microbe action leading to additional costs.

And the preferable cleanup method depends on natural processes, thereby reducing the risk of damaging the ecosystem. The process is usually done underground, where amendments and microbes can be introduced to clean up groundwater and soil, causing minimal disturbance to the nearby community. This cleaning method is cheaper than other cleanup methods since it does not need costly types of equipment and intense labor to implement instead of other methods.

By the end of the year 2017 Biological代写

The United States Environmental protection agency had cleaned up more than 1,500 sites using bioremediation. Bioremediation is not a new method, but its knowledge of usage has increased over the years. This process can be tailored to meet the growing population’s needs with increased microbial reactions in practice. The underlying question is to introduce specific microbes needed to break down contaminants. Mainly these microbes are selecting the crucial limiting factor needed to promote their growth.

Despite many advantages of bioremediation, there is also the limitation of using it in various environments. When dealing with highly chlorinated pollutants and contaminants with high molecular weights are not readily amenable through microbes. Also, some chemical, microbial degradation may result in more dangerous compounds harmful to the environment than the primary compounds. For example, bioremediation of dehalogenation of TCE can result in a hazardous vinyl chloride compound, which is very toxic and carcinogenic.

CONCLUSION Biological代写

Bioremediation is an emerging method of reducing environmental pollution, which can be used together with another physical and chemical treatment method to yield more positive outcomes when dealing with various environmental pollutants. There is a need for intense research on this method since it seems suitable and environmentally friendly.

Efforts should be made to create a synergistic interaction between the most effective bioremediation technique’s performance and the environmental impact on environmental pollutants’ fate. Moreover, the application of bioremediation to either natural or artificially created environments can be predicted using multidisciplinary technologies to yield a more positive outcome.
