A common mechanism by which sensor cells in the host detect micro-organisms relies on the production of unique microbial components not found in the host. Propose a strategy by which a clever microbe could evade this type of response.
Design a concept map on microbial growth that would contain the key features of the following concepts (Requirements of microbial growth, Bacterial Growth, Control of Bacterial Growth and Antimicrobial methods).

- Provide an example of an organism within each of the four main nutritional categories of microbes and describe how each obtains its essential nutrients. 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. Summarize how the electron transport chain functions to produce ATP in a bacterial cell versus eukaryotic cell. Explain whether or not the term chemiosmosis accurately illustrates this process.arrow_forwardDiscuss the possibility of life on Mars. In reference to extremophiles. Defend or refute this statement: The upper-temperature limit to life is unrelated to the stability of proteins or nucleic acids. How influential is microbial activity on the geological processes of mineral formation and deposition compared to biological processes? (argue both sides of this one). What challenges and advantages do you see with the use of extremeophiles in industrial or bioremediation applications?arrow_forwardFor Mycobacterium tuberculosis In this part, you will describe how the microbe interacts with other organisms and/or the non-living environment. Choose the most pertinent interactions for your microbe. For example, if your microbe is a human pathogen, focus on the interaction with human cells and the immune system. If your microbe is a nitrogen-fixer, focus on the interaction with other organisms via the nitrogen cycle. aim for including at least 5 key points regarding the interactions and describe those points in detail please write a new heading for each of your key points so that it's clear to me what the 5 points arearrow_forward
- A researcher is interested to test the antibacterial activity of a Philippine Plant crude extracts against Beta-lactamase producing Klebsiella pneumonia isolated in a hospital setting. He will use the following concentrations of crude extract, 500mg/ml, 250mg/ml and 100mg/ml. Positive control: Tetracycline 10mg/ml and DMSO as the negative control. Given this research scenario kindly construct a research framework.arrow_forwardA study of microbial pathogen transport in an aqueous environment is to be studied. The target microorganism is Escheria Coli with a characteristic length of 25 micrometers. The pathogen moves at a rate of 2.5 micrometer/second. What model fluid should be used?

The colleague states that bacteria A is strict arobe. Is this correct, explain reasoning in a couple sentences. B. Another colleague states that bacteria B must be a strict anarobe. Is this correct, explain reasoning in a couple sentences.arrow_forwardGiven this research scenarios kindly construct a research framework.

Nutrients must diffuse through the layer in order to sustain the organisms throughout the film. A typical biofilm thickness is 0.01 cm and the diffusivity of the nutrients in the biofilm layer is estimated as 0.8 cm^2/day. A. Assume that the concentration in the bulk fluid and at the solid surface are both constant. Derive a general expression for the steady-state concentration profile within the biofilm. (hint: recall that Fick's second law of diffusion can be used to solve for concentration profiles.) B. If the bulk and surface concentrations are 3.2 mg/liter and 0.25 mg/liter respectively,what is the expression for the concentration profile in this specific case? C. Calculate the flux of nutrients at the solid surface and at the interface with the bulk fluid. D. Explain the reasonableness of your answer.arrow_forward
