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.

- Bacteria reproduce by fission (splitting in two) and can respond very rapidly to environmental changes. A culture of bacteria is found to contain 4.95 X 109 bacteria and the carrying capacity of the culture is 5.0 X 109. How will the bacterial population change in the near future. Group of answer choices -it will increase very rapidly to K -it will increase very slowly to K -it will grow exponentiall -it will decrease very rapidly to KConsider the following graph depicting the population growth of bacteria in an “ideal” laboratory created condition. Explain what conditions would allow for a population to grow exponentially like in this example, and why this is unlikely to occur naturally in the wild. ✓✓ Population (number of bacteria) 35000 30000 25000 20000 15000 10000 5000 0 Population Growth of Bacteria in Ideal Conditions 2 Time (hours) 35a. On the following figure to the right, correctly label the name of the population growth pattern that the red line and the blue line demonstrates. 5b. Match the following growth equations to the growth curve by drawing a line between the equation and the curve or placing the name of the growth pattern next to the equation. dN (K-N) rN -- dt K dN = rN dT %| Time (t) → 5b. What does K in this figure represent? How and why do population growth rates change as the population nears K? Population size (N)
- A bacteria culture starts with 140 bacteria and grows at a rate proportional to its size. After 5 hours there will be 700 bacteria. (a) Express the population after t hours as a function of t. population: 140 * e^((0.321)(t)) (b) What will be the population after 7 hours? (c) How long will it take for the population to reach 1870 ? (function of t)what is k and r for each condition? K (carrying capacity): can be estimated by finding the point where the growth curve levels off. Take the average of this data point and all data collected beyond this point to estimate k (note: if the bacteria population is still growing, you can just take the last value of data for k. r: choose any two points at the log phase of growth. Then use the r formula. Just choose two waste conditions for r and k calculation so I can get the idea of how to do this, thanks.An exponentially growing bacterial population increases its number from 10³ to 104 cells in 8.5 hours.

- The following questions refer to the information and figure below. Experimental populations (average) 1.8 - 1.6 1.4 1.2 - Ancestral population 1.0 5000 10 000 15 000 20 000 Generation In this eight-year experiment, 12 populations of E. coli, each begun from a single cell, were grown in low-glucose conditions for 20 000 generations. Each culture was introduced to a fresh growth medium every 24 hours. Occasionally, samples were removed from the populations, and their fitness in low-glucose conditions was tested against that of members sampled from the ancestral (common ancestor) E. coli population. Which of the following is less likely to promote bacterial survival over evolutionary time in a low- glucose environment? Increased sensitivity to, and ability to move toward, whatever glucose is present in its habitat Increased ability to synthesize glucose from amino acid precursors Increased efficiency at transporting glucose into the cell from the environment Increased ability to survive…An exponentially growing bacterial population increases its number from 10³ and reached 10¹ cells in 8.5 hours How long will it take for the population to reach 10¹8 cells? 19.5 hours 10.5 hours 11.5 hours 12.5 hours Lacks information, cannot be determined NextAn exponentially growing bacterial population increases its number from 103 to 1010 in 4.5 hours and reached 10¹4 cells in 8.5 hours.
