Solved in 2 steps
- Show your solutionQuestion:- Define the bacterial categories that each type of bacteria belongs to. You only have to name the categoriesNOT the actual species of bacteria Note: there will be more than one category . A bacterial species that grows best at 37 degrees Cand when a small amount of oxygen is presentEx. 3 Questions 1 A pure culture has one type of bacteria growing, a mixed culture has multiple types of bacteria, and sterile media has nothing alive (viable) in it. Can you determine whether or not a bacterial culture grown in broth is a pure culture by visually inspecting it without a microscope? In an agar deep? On a slant? On a plate? Explain your answers. 2. Do the different species of bacteria appear the same or different from each other when grown in media? Do you think it would be easy to identify which of the three species you had just by descriptions of growth? Explain your answer. 3. What is the purpose of flaming the loop after you have used it to transfer bacteria? 4. Can you tell the difference between sterile media and bacterial cultures (media with bacteria growing in/on it)? How can you tell?
