2. Some bacteria will only grow when they have access to specific types of nutrients. If some bacteria in the yogurt would only grow in milk, and would not grow on agar, how would this have affected your investigation?

1. Why was it important to inoculate milk with bacteria from a single colony rather than from multiple bacterial colonies?
2. Some bacteria will only grow when they have access to specific types of nutrients. If some bacteria in the yogurt would only grow in milk, and would not grow on agar, how would this have affected your investigation?

1. Research. Look up, the types of bacteria commonly found in yogurt.
2. Can the bacteria responsible for making yogurt be prevented from turning mile to yogurt? How? 1. What does it mean to be concise?
2. What do I not want to see in your flowchart? 1. What characteristics of bacteria make them good at causing disease?
2. How can the spread of infectious pathogens be prevented? 1. How will we be modeling Koch's postulates in this lab?

2. What is happening inside the zone of inhibition? outside the zone? 1. If you needed to identify the source of a disease, how would you do it?
1. What can bacteria be used for?
2. In microscopy, what is a wet mount? 1. What is the purpose of Koch's postulates?
2. By isolating bacteria, what characteristics might you determine? What equipment might you need? 1. For the Kirby-Bauer test, what sample were you surprised to see has antibacterial properties?
2. 1. For the Kirby-Bauer test, what sample were you surprised did not have antibacterial properties? |
