- Aeroderma pigmentosum patients have a 10,000-fold increase in the risk of developing Skin cancer. These patients have to avoid exposure to UV light. Please explain why. To answer the question please: I) name the process that is affected and provide a scheme; 2) indicate template, substrates, sources of energy that are involved in the process; 3) propose the consequences of the process.As a clinical microbiologist, your job is to identify an infectious bacterial strain isolated from a patient. Phenotypically, you have discovered that the new bacterial strain can grow in the presence or absence of oxygen. By growing the strain in glucose carbohydrate tubes, you found that the organism is positive for glucose fermentation. After genome sequencing and biochemical analysis, you know that your organism is capable of making all of the enzymes necessary for glycolysis, and that it contains a TCA cycle and an electron transport chain.https://courses.lumenlearning.com/microbiology/chapter/controlling-microbial-growth/ Read this Article about Controlling Microbial Growth and answer the following questions: Which is most effective at removing microbes from a product: sanitization, degerming, or sterilization? Explain. What are two possible reasons for choosing a bacteriostatic treatment over a bactericidal one? Name at least two factors that can compromise the effectiveness of a disinfecting agent.
