- Microorganisms are needed in wastewater treatment facility to do the actual breakdown and removal of nutrients and organic matter in the waste matter. One day, the employee who is in-charge of the facility notice that as the time goes by after the wastewater was loaded into the medium the metabolic activity of the microbe cease to increase and remain stable instead. Within the context of our discussion, what could be the possible explanation for the employee’s observation?3. (a) Comparing the culture-dependant (e.g., colony forming units count) and DNA- based (e.g., PCR) bacterial number quantification methods, what are the primary disadvantages of using culture-dependent methods to quantify bacterial numbers in an environmental sample? Use no more than three sentences or bullet points to present your answer succinctly.What is an advantage of in-situ bioremediation as a means of eliminating contaminants over chemical decomposition and excavation?

Provide evidence in support of or refuting the following statement: Microbial life can exist in the complete absence of both sunlight or organic nutrients. Polymerase chain reaction (PCR) is a technology that requires high temperatures to reproduce DNA fragments. Explain why the discovery of thermophilic archaea and their associated DNA polymerases was critical to the success of this technique.
