Question

Thus far, you have primarily studied microbes in a medical capacity and have explored many disease-causing microorganisms. Prokaryotes are deeply connected to the environment, and humans depend on them in a variety of ways. In your unit Assignment, you will explore important roles that microorganisms play in the world around you. Your Reading for this unit will serve as an excellent resource for examples and information. Assignment Instructions 1. Define and describe bioremediation. What is it, and how does it help the environment? 2. Discuss two examples of specific microorganisms (bacteria, fungi, etc.) that are used to remove pollutants through bioremediation. Provide the scientific name (genus and species) of the two microbes selected, and briefly describe their role in bioremediation 3. Bioremediation can come in many forms. There are many approaches that can be taken to address diverse perspectives while also providing benefits to the broader community. In a summary paragraph: . Discuss two examples in which bioremediation can be used to meet d global challenge . Discuss the benefits of each example (for example, there are different approaches to reducing water pollution or improving the health of the environment) . What are the benefits of each approach? You have the option of presenting your Assignment in one of the following three formats a. Word document Submit a 700-900 word paper in APA format including an introduction, conclusion, and in-text itations and reference page

Explanation / Answer

1.Bioremediation is a process in which biological products such as microorganisms are used to treat or break down environmental pollutants in soil, water or any surface.

Bioremediation is less expensive and less hazardous compared to other conventional approaches.

2. Toluene, which is an ingredient in paint thinner, contaminates the soil. Pseudomonas putida is a Gram negative bacteria that is used in toluene bioremediation.

When fungi are used for bioremediation, it is called mycoremediation. Phanerochaete chryosporium is the fungi used for degradation of organic pollutants. It has also been shown to remove pesticides effectively.

3. several forms of bioremediation: mycoremediation, phytoremediation, bioleaching etc.

Bioleaching is the extraction of metals fromm their respective ores using microorganisms. Conventional approaches to extract metals from ores require use of toxic chemicals that get accumulated in soil. Eg., Acidithiobacillus ferrooxidans is an iron and sulfur oxidizing bacteria.
