Step by step
Solved in 2 steps
- Why are infections that involve biofilms a concern?What are the four basic stages of biofilm formation?Biofilms represent an important environmental niche. A) How does growth on a surface differ from growth in a suspended laboratory culture? (In other words: How do biofilm-forming cultures differ from planktonic cultures) B) Describe the stages of biofilm development including cellular and extracellular components?
- How are biofilms significant to the human body and the environment?Diseases that involve biofilm-producing bacteria are of serious concern. They are not as easily treated compared with those involving free-floating (or planktonic) bacteria. Explain three reasons why biofilms can be more pathogenic.What do you think is more influential on the types of bacteria or other microorganisms that are involved in biofilm formation – the physical environment or the solid substrate on which it forms? Why?
- Describe the basic process of biofilm formation.What are examples of a bacterium that produces a biofilm ?In the exponential phase of microbial growth, Log cell numbers Time O a) net cell growth is equal to net cell death. Ob) net cell growth is greater than net cell death. c) waste accumulates, cell death is greater than cell growth. d) the cells stop growing.
- Biofilms represent an important environmental niche. A) How does growth on a surface differ from growth in a suspended laboratory culture? (In other words: How do biofilm-forming cultures differ from planktonic cultures) B) Describe the stages of biofilm development including cellular and extracellular components? C) What processes regulate might regulate biofilm formation? Is quorum sensing involved and if so, how common is it? D) Why would biofilms promote the formation of genetic variants? What are the mechanisms by which this might occur? These questions are all related.Describe a microbial biofilm. Discuss why it is likely that a biofilm contains bacteria with different energy metabolisms?In microbiology, the term growth in a culture usually refers to an increase in O 1) the number and size of microbial cells. O 2) the amount of ATP consumed. O 3) a microbe's size. O 4) the number of microbial cells. 5) the amount of ATP produced.
