- The process of collecting characteristics of your unknown bacterium can be helped by the use of a dichotomous key. A dichotomous key is a flowchart that can be used to identify an organism. a) in your own words explain how to create and use a dichotomous key to identify unknown bacteriaMannitol salt agar is often used to distinguish between different species of Staphylococcus, a gram positive bacterium that is well adapted to living on dry, salty skin. Disease-causing strains of Staphylococcus ferment mannitol; non-pathogenic strains cannot use mannitol. Is the medium Defined or Complex?How would you produce a 10^-1 dilution if a 3 mL bacterial sample using the entire 3 mL volume? suppose your professor handed you a test tube with 2.0 mL of an E. coli broth culture in it and told you to make a 10^-1 dilution of the entire culture. Explain how you would do this. Show your calculations.
- Using a dilution series is a way to transfer the very small volumes of original culture necessary to get countable colony forming units. If you suspect your culture of bacteria has 59.62*10^9 cells per mL, how many mL of original culture would you want to end up on the plate to produce 68 cfu? Express your answer in scientific notation rounded to two decimal places. Eg. 0.01001 would be 1.00*10^-2 You must include trailing zeros 0.0000040001 would be reported as 4.00*10^-6 There must always be two decimal places, even if they are zeros Canvas expects one digit before the decimal point 0.40*10^-5 would be marked incorrect for 0.0000040001You perform the Methyl-Red(MR)& Voges-Proskauer(VP)test and gather the followingresults: (Uploaded picture). VP test result is on the left, MR test result is on the right. A) Please interpret these results. B) Your fellow researcher and yourself are sure your bacterial sample is either E. coli or P. vulargis. Basedupon the work we have done in lab which methods will help you determine which bacteria it is? Please explain why, the results you would want to observe and provide analysis of those results.The images attached are the photos of bacteria in yoghurt under a misroscope. According to these images and your own knowledge, can you make a biological drawing of bacteria in yoghurt ( in a circle) and identify the types of bacteria accurately?
- Identify the shapes and arrangements of the following bacteria observed under the microscope. Recall: look for the arrangement seen with most cells; you may see another arrangement that is less common. option: diplo, bacillus, negative, coccus, positive, staphylo, strepto. Gram stain Cell arrangement Cell ShapeTRY TO KEEP IN SHORT AND USE OWN WORD FOR THIS QUESTION You are studying a type of bacteria isolated from the acidic water runoff of a mining operation. You subject two batches of the same bacteria type to different environmental growth conditions. One batch is grown at pH 2, while the other is grown at pH 7. All other environmental parameters are kept identical between the two batches. You then collect their proteins and run a Western blot using an antibody that binds to a proton efflux pump protein (which actively expends energy to pump protons out of a cell). How would you characterize the information obtained in this experiment? What does it tell you, and why is that potentially valuable information?Identify the shapes and arrangements of the following bacteria observed under the microscope. Recall: look for the arrangement seen with most cells; you may see another arrangement that is less common. option: spirillum, strepto, positive, bacillus, staphylo, negative, diplo Cell shape ? Gram stain ? Cell arrangement ?
