MODEL ANSWER

Introduction

            Bioremediation refers to a process used to treat pollutants or contaminated media, which include soil, water, and subsurface materials. It involves changing environmental conditions to stimulate microorganisms’ growth while degrading the target | PLACE YOUR ORDER NOW AT writtask.com | s more sustainable and less expensive than other alternatives for remediation. A similar approach is a biological treatment for treating such wastes as solid waste, industrial waste, and wastewater. Bioremediation helps the environment through | PLACE YOUR ORDER NOW AT writtask.com | processes of bioremediation comprise oxidation-reduction reactions where either oxygen (electron acceptor) is added to stimulate oxidation of hydrocarbons (reduced pollutant) or electron donors added to reduce oxidized | PLACE YOUR ORDER NOW AT writtask.com | approaches, vitamins, additional nutrients, pH buffers, and minerals to optimize conditions for the | PLACE YOUR ORDER NOW AT writtask.com | (specialized microbial cultures) is added to further biodegradation of waste to improve the environment.

Bioremediation

           Bioremediation uses living organisms to break down pollutants into less harmful, natural | PLACE YOUR ORDER NOW AT writtask.com | also known as bioremediation, and are mostly bacteria, fungi, and archaea because of their rapid rate of growth, ability to be manipulated genetically, and has variable metabolic needs (Magan et al., 2010). In this case, the microorganisms used to remove pollutants via remediation include bacteria and archaea. Bacteria, for instance, are widely diverse, and have significant impact bioremediation, especially when given the right conditions. An example of bacteria playing a major role in bioremediation is Pseudomonas putida, while an example of fungi is of Phanerochaete chrysosporium (Azubuike et al., 2016). Pseudomonas putida is involved in the bioremediation of toluene, which is part of the paint thinner, as well as degrade naphthalene, a petroleum refining product in contaminated soils (Ojuederie & Babalola, 2017). On the other hand, Phanerochaete chrysosporium is linked to degrading organic pollutants.

           Bioremediation can occur in many forms, and many approaches can | PLACE YOUR ORDER NOW AT writtask.com | two examples in which bioremediation can be adopted to meet a global challenge fall into two categories namely in-situ and ex-situ. An example of the in-situ bioremediation treatment method is biostimulation, while the ex-situ bioremediation treatment method includes biopiling.

Biostimulation comprises the addition of nutrients to polluted sites to encourage the natural | PLACE YOUR ORDER NOW AT writtask.com | by adding various nutrients, which are limited in the soil and such electron acceptors as oxygen, nitrogen, and phosphorus. Other approaches under biostimulation include the optimization of environmental conditions such as adding nutrients, aeration, temperature control, and altering pH. 

Biopiling, on the other hand, is an example of how bioremediation can be used to meet global environmental | PLACE YOUR ORDER NOW AT writtask.com | the excavation of soils mixed with soil changes; biopiles are, in turn, aerated with using blowers and perforated pipes to control the biodegradation progression more efficiently through the control of oxygen supply that potentially affects other factors like pH. According to Ojuederie & Babalola (2017), the treatment approach system is primarily used to remediate systems with hydrocarbon and | PLACE YOUR ORDER NOW AT writtask.com | remediated soil is lined to prevent further contamination of soils; they can also be covered by plastic to control evaporation, runoff, and volatilization. 

There are two major remediation types conducted either in ex-situ (done by removing the contaminated water or soil, and treating it outside the source) | PLACE YOUR ORDER NOW AT writtask.com | treatment methods may be combined, and some techniques may involve mobilization of pollutants to improve the environment. With examples under these two categories, there are associated | PLACE YOUR ORDER NOW AT writtask.com | of the benefits of bioaugmentation, in line with the improvement of the environment, comprise its cost-effectiveness, noninvasive nature, and uses various natural attenuation processes to treat water and | PLACE YOUR ORDER NOW AT writtask.com | depend significantly on various factors for consideration namely the biodegradative abilities of indigenous microorganisms, and the use of various environmental parameters to identify and distribute metals and other inorganics…
