- Question: Cultures of a bacteria strain were incubated in a refrigerator (5oC), on a lab bench (22oC), in a 37oC incubator, and in a 50oC incubator. After incubation, there was no growth at 37oC and 50oC, slight growth in the refrigerator, and abundant growth on the lab bench top. Which term best describes this organism?
- Question: A bacterium is inoculated into a tube of thioglycollate and incubated. After incubation, turbidity appears throughout, top to bottom, with the greatest turbidity at the very top. This bacterium would be called a(n) _________
