Each of the following statement FALSE. Tell me what is incorrect with the statement and correct it when possible. For example, if the statement says: the sky is red during daytime. You would answer: the sky isn’t red during daytime, it is blue. a. Staphylococcus aureus use MreB proteins to organize their morphology (shape) into cocci. b. Most bacteria will have maximum growth in a glucose-rich environment such as maple syrup. c. The table below shows that Streptococcus pyogenes is a facultative halophile. d. Your lab supervisor asks you to grow a new bacterium they got from a collaborator. You grow them in the suggested nutrient-rich media, and you notice that as the log phase growth progresses, the bacteria seem to turn purple. You mention it to your supervisor and ask whether it is the gradient from very high to low nutrient bioavailability that induces metabolic changes which induces the production of a purple pigment. Your supervisor tells you that is unlikely. What is a more…

Before using the API® 20E System, what test must be performed to confirm the identity of your unknown as a member of the family Enterobacteriaceae? Why is this important, and what is the expected result?

Kligler’s Iron Agar:Q10) Give me the expected results for Pseudomonas aeroginosa, Salmonella typhimurium, and Escherichia coli. Pseudomonas aeroginosa, Salmonella typhimurium Escherichia coli.

Enterobacter aerogenes inoculated into a glucose fermentation tube often gives a weak acid result (orange-yellow) with a very large bubble in the Durham tube. If it ferments glucose, why might the tube not turn very yellow?
