Chapter 2, Problem 10SA

Biofilms are a community of microorganisms that can colonize surfaces and are located in a wide variety of places. Provide some information regarding biofilms that you read about in your textbook, on the internet (use a valid resource site), or any other source that you found related to biofilms in general. This can include characteristics, types of organisms that may be present, locations, what type of outcome they can lead to, etc. This particular topic has a lot of information overall, so write about something you fınd interesting!

Your instructor asks you to determine the number of organismsin a water sample. Observation of your dilution plates revealsthe presence of spreading colonial forms on some of the culture plates.What is the rationale for the elimination of these plate counts from yourexperimental data?

Which of the following is correct about biofilms? O 1) They are comprised only of psychrophiles. O 2) They are more sensitive to changes in growth conditions than planktonic cells O 3) Quorum sensing allows the biofilm community to behave differently than planktonic organisms 4) Biofilms only form within the environment. 5) Pure cultures are necessary for biofilm formation.

Why is it important for all plankton monitors to use the sample protocol for both sample collection and identification?

Create a short paragraph to differentiate among the following terms: pure culture, subculture, mixed culture, contaminated culture, and stock culture

Can you discuss the potential of the living battery technology for the remediation of sediment? What are the pros and cons? What are the physical limitations for the bacteria involved as well as the deployment of such systems? Thank you

Write an abstract of the article below in Methods (around 3 sentences):                                                      METHODSTo accomplish this, three kinds of inocula - Pond bottom soil 1, Pond bottom soil 2 and Horse dung - wereobtained from two different ponds and outdoor loafing sheds near Keller, Texas. Waste samples, including food,paper and yard waste, were collected from a house. Three laboratory scale reactors were prepared with selectedhousehold waste and inoculum with the required amount of water and operated at room temperature. Duplicateruns were conducted for the first set of experiments. The pH level of reactors was controlled by adding sodiumhydroxide.

Describe several ways in which coliform bacteria are known to get into well water. (Do Internet research; use reputable sources; cite your sources appropriately in your answer)
