Week 2 Discussion BIO2071 Microbiology Lab
The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered.
To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format.
Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion.
Using the South University Online Library or the Internet, research about biochemical tests. Based on your research and readings, respond to the following:
- Why is it important to have a pure culture and not a mixed culture when performing biochemical tests?
- How does culturing an organism on several different types of media help identify an organism in a relatively short period of time?
- What is the technique used to isolate pure cultures from a specimen that contains mixed flora? Describe the technique.
- What are the characteristics by which bacterial colonies may be distinguished? Describe at least four such characteristics.
