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...
