- Situation 1 You are required to make two agar plates, one containing Escherichia coli and the other Staphylococcus aureus. The liquid E.coli sample is stored in a screw-capped tube while S. aureus is in a petri dish. To make an agar, you should dissolve the agar powder in water. • What will you use (laboratory equipment) to transfer the E.coli sample? • In what equipment will you put the two freshly inoculated agar plates? • If you need 27.5 mL of water, which glassware is used to accurately measure it all at once? • If you are done using the S. aureus sample and the other class will use it tomorrow, where should you store it? • What will you use to sterilize the inoculating needle? * • What glassware could be used to mix the agar powder and water mixture? • What glassware is involved in agar plates? What is the BEST glassware that could bewhat are some of the strengths and weaknesses to using a Culture dependent enumeration approach from a microbial perspectivehttps://courses.lumenlearning.com/microbiology/chapter/controlling-microbial-growth/ Read this Article about Controlling Microbial Growth and answer the following questions: What are some characteristics of microbes and infectious agents that would require handling in a BSL-3 laboratory?

I have to make 4 power point slides regarding this topic. Can you give some information about the topic which i can use in the slides? Also provide some necessary relevant diagram or image regarding the topic. Please answer at your own easy words. If you do so i will rate you positive, Thank you.
- Would you use an inoculating loop to transfer bacteria to an agar deep tube? Would you use an inoculating loop to transfer bacteria to an agar deep tube? Yes, as long as you insert the loop into the agar smoothly. No, a needle would be best since it will do the least amount of damage to the agar and allow it to reseal around the inserted bacteria. It depends on which bacteria you are transferring. Yes, as long as you are careful when streaking on the surface of the agar.What are the advantages and disadvantages of plate count technique over other methods of quantifying microbial populations?Watch this video and answer all of the following questions in detail: https://www.youtube.com/watch?v=PbgB2TaYhio What was missing in Dr. Llyod's Petri dish experiment for the microbes to grow? How much time is it estimated that these microbes would need to grow? What would be one biotechnological application afforded by learning more about deep subsurface microbes?
- You are tasked with quantifying bacteria in your soil sample. You resuspend 1.0g of soil in 10 ml 1x PBS, then do a 10-fold serial dilution of your soil sample. You plate 150 µl onto each plate. The 104 dilution plate contains 175 colonies after 2 days of incubation, how many bacteria do you estimate were present in your initial soil sample? (# colonies/volume plated in ul) * dilution factor * ul convert to ml * volume suspended soil (ml/g) = Read the formatting instructions below before entering your answer! 1. Make sure your answer is in correct scientific notation using an "e" to indicate the exponent! For example, 2500 would be 2.5e3, 0.0066 would be 6.6e-3. 2. For answers greater than 1, round up to the nearest tenth. For example, 2515 would be 2.5e3 and 51510 would be 5.2e4.Answer the following questions briefly and concisely 1.How do bacteria in a chemostat and those in a batch culture vary from one another? 2. What happens in a chemostat if the dilution rate is higher than the organism's maximum specific growth rate? 3.Does a chemostat require the use of pure cultures? 4. Why would a complicated culture media for Leuconostoc mesenteroides be simpler to make than one with a fixed chemical composition?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.
