A microbiologist used the concept of enrichment culture to isolate aerobic and anaerobic nitrogen-fixing bacteria, sulfate-reducing bacteria, and sulfur-oxidizing bacteria. What kind of selective media could he haveused for isolating each of these four classes of microbes?
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.

- The term "turbidity" in microbiology refers to: a cloudy appearance in broth, meaning microorganisms did grow a cloudy appearance in broth, meaning microorganisms did not grow a clear appearance in broth, meaning microorganisms did not grow the clump of cells at the top of a broth a clear appearance in broth, meaning microroganisms did growarrow_forwardYou 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.

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 reasoningarrow_forward
- Microorganisms are needed in wastewater treatment facility to do the actual breakdown and removal of nutrients and organic matter in the waste matter. One day, the employee who is in-charge of the facility notice that as the time goes by after the wastewater was loaded into the medium the metabolic activity of the microbe cease to increase and remain stable instead. Within the context of our discussion, what could be the possible explanation for the employee’s observation?arrow_forwardMicrobes are exposed to a wide variety of environmental factors that affect growth and survival. By giving two (2) examples, discuss how the microbial survival in various environmental conditions has been used to understand its ability to make flavorful and long shelf-life type of foods.arrow_forwardYou 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_forward
