Microbial Physiology

Microbial physiology is the branch of microbiology that is associated with studying the physiology of fungi, bacteria, and viruses. It is an important field of science concerning functional genomics and metabolic engineering.

Chemotaxis

The organism’s movement in a particular direction as a response to certain chemicals that are available in the environment is defined as chemotaxis. In brief, it can be defined as the occurrence of an organism’s movement in response to a certain chemical stimulus.

Jessie is working with a 100% stock concentration of Clorox. She decides to add 100 µL of bacteria to a tube containing 3 mL of nutrient broth and then adds 400µL of the Clorox stock to the tube as well. What is the unknown concentration of the tube?
You are given an unknown bacterium in the lab and have to determine unknown bacterium's oxygen needs. You place the organism in a shake tube and after 24-hours observe significant turbidity near the surface of the media and the turbidity decreases as you move toward the bottom of the tube; however there is still apparent growth. How do you classify this organism? O Microaerophile O Facultative anaerobe O Obligate aerobe O Obligate anaerobe Question 14 1 pts
Material (wound discharge) from a patient with suspected anaerobic wound infection was sent to the bacteriological laboratory. It is necessary to isolate a pure culture of anaerobic bacteria. 1. What principle of isolation of pure culture of anaerobic microorganisms will be applied? 2.

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
1) Listen In the lab you are testing a bacterium's oxygen requirement for growth. You grow your bacterium in a test tube, without shaking at the appropriate temperature. The next day you find that your bacterial culture is growing only at the top surface (ie at the top of the tube closest to the cap) and not dispersed throughout the test tube. What term would be used to describe the oxygen requirement of this bacterium? O A) Obligate aerobe. O B) Microaerophile. O C) Anaerobe. D) Obligate anaerobe. E) Facultative anaerobe.
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.
After incubating for 24-48 hours, you retrieve your 4 agar plates for the osmotic pressure exercise from the 37°C incubator. You observe the following results: • Sa = Staphylococcus aureus • Pv = Proteus vulgaris Sa For each organism, you should indicate in the text box below: 1. At what salt concentrations (osmotic pressures) you saw growth. 2. The classification term you would use in order to classify the organism based on osmotic pressure. Choose your term based upon where you observed growth; not optimal growth. Each organism has only one classification term associated in describing its growth pattern(s). You will need to use the osmotic pressure classification descriptions and terms outlined in your lab manual.
