- Which of the following is true of microbial biofilms? A. Biofilms are restricted to freshwater environments. B. Biofilms typically are small because resources such as nutrients and oxygen are unable to circulate through them. C. Cells within the biofilm are encased within a layer of polysaccharide. D. Biofilms almost always consist of only a single bacterial speciesWhich of the following is not true about biofilms a) are caused by many Gram positive and Gram negative bacteria as well as algae and fungi b) are highly contagious c) are hard to treat due to impermeability to drugsBiofilms 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?

They are not easily treated compared with those involving free-floating bacteria. Explain three reasons why biofilm formers are more pathogenic.
- QUESTION:- All of the following are characteristics of biofilms except for: - There are variations in the environment within biofilms- Transfer of genes between microbes occurs in the interior of biofilms- In biofilms there is often metabolic cooperation- Biofilms can form on surfaces where nutrients are limitedDiseases 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.For a bacterium that prefers a neutral pH and has an optimal (best) growth pH of 7, how would growth of this bacterium at pH 4 most likely compare to growth at pH 7? Growth would be slower (or the bacterium might die) at pH 4 Growth would be faster at pH 4 Growth would be the same at both pH values
- Which of the following is not involved in quorum sensing?a. accumulation of inducer moleculesb. a certain level of biofilm densityc. self-monitoringd. release of genetic materialAre the biofilms in the soil distinctive base on what the soil is growing or all are biofilm all alike? Meaning do we find some organisms( helps the plant) grow in a certain plant and not in other.Explain what is happening with this graph that charts the reactions ofa mesophilic bacterium to temperature. Blue shows the survival curveand brown the growth curve under various temperatures.
