Question 6 1.5 points Save Answer Bacterial ID Flow Chart.docx A student in a microbiology lab was assigned the task of determining the identity of a bacterial species. First she performed a quadrant streak on a TSA plate. After 24 hrs. incubation, she aseptically picked up a portion of a single isolated colony for a gram stain. Her results indicated purple spherical-shaped bacteria that grew in grapelike clusters with no apparent endospores. She then performed a series of biochemical tests...

p. If you accidentally forgot to inoculate your organism in an OF-glucose tube with oil, and only had one yellow “no oil” tube, what type of carbohydrate catabolism would describe that organism (fermenter, oxidative, neither)? Explain your answer. q. What are two other results from the OF-glucose tubes other than their type of carbohydrate catabolism? r. How can organisms that don't use starch grow on a starch agar plate? Carbohydrate Catabolism...
