Textbook Question
Chapter 3, Problem 10CTQ
You are a scientist studying a marsh area contaminated with PCBs, toxic chemical compounds found commonly in industrial waste. Initial microscopic analysis of the soil reveals the presence of motile cells that measure in the micrometer range. You hypothesize that these microbes may be useful in bioremediation of the toxic waste. Thinking about microbial sampling and isolation, describe a method for culturing these microbes back in your laboratory.

Suppose you are checking the microbial quality of a raw material
using agar culture media. After doing the culture, you found the
growth of unwanted microbes. What will you do next?
Your answer
Suppose you observed a bacterium growing on Mannitol Salt agar (MSA) with a yellow colony appearance in the clinical microbiology lab. Name the genus and species you are most likely observing; state its most likely oxygen needs and salt requirements; and predict if this organism would grow on MacConkey agar or Colistin Nalidixic Acid agar. If you want to control the growth of this organism in a healthcare setting, predict what disinfectants would be best to use and their modes of action. Explain your reasoning
The use of culture-independent techniques has increased our understanding of microbial diversity without cultivation. Therefore, do microbiologists still need to attempt to grow new microbial species? Explain.

- You were tasked to aseptically collect different environmental samples from a quarry site and process them back in the laboratory for microbial cultivation and analysis. After all the thorough experiments, you were only able to cultivate and study 36 microorganisms. However, based on the metagenomic analysis conducted, there are about 140 other species present in the samples collected. Why is this the case? Discuss and expound on the possible reasonarrow_forwardScreening is a selective procedure to allow the detection and isolation of only those microorganisms of interest from among a large microbial population. How can screening improve the desirable traits of industrial microorganisms?arrow_forwardAssuming you are working in a microbiology laboratory and a client sent you a sample for the following analyses: Identification of all microorganisms in the soil sample Enumeration of culturable bacteria in the sample Enumeration of both culturable and non-culturable bacteria in the sample For a to c, explain the following: Method of analyses to be used Step by step report on how the analyses will be conductedarrow_forward

- What is the difference between culture media and cultural environment? Are environmental conditions related to specific microbes? If so, which conditions for which type of microbes? If you were a field researcher collecting microbes in the wild, what kind of data would you take to make sure you know the exact environment the samples require in order to culture them in a lab?arrow_forwardWhat microbial control method would you use to clean a papercut? Why did you make that choice? Explain your reasoning . Need answer in short and very ASAP .arrow_forwardBecause so few organisms can be successfully cultivated in the laboratory, studying only those that have been isolated often does not give an accurate picture of what actually happens in nature.

- You are responsible for the bioremediation of soil contaminated by jet fuel. Your coworker suggests you fertilize the soil with nitrogen and phosphorus to promote the growth of naturally occurring hydrocarbon-degrading microbes. However, you just read about a new mixture of microbes sold in a slurry with nutrients and a surfactant. What data do you need to collect to decide which approach would be best? How will you obtain these data?arrow_forwardAfter quick-characterization by staining, specialized growth media can be used to indicate further biochemical characteristics of an unknown organism. These tests use visual outcomes, such as colors, patterns, and changes in appearance. The results can be interpreted to then assign a characteristic to the unknown organism. For example, a color change may happen when an unknown organism is incubated in a mixed sugar broth. The color could indicate which sugar was (or was not) used by the bacterium for energy. a) explain in your own words how to perform specialized media tests to find an unknown bacteriaarrow_forwardIn lab, sterile technique is important for what reason? none of the answers are correct to ensure that we have not introduced outside microbial variables to prevent our samples from being contaminated with human samples all of the answers are correct to prevent us from getting sick with microbesarrow_forward
