Characteristics | ||||
Obligate anaerobic | Obligate aerobic | Facultative anaerobic | Facultative anaerobic | |
Gram status | + | − | − | − |
Optimal temperature (°C) | 10–40 | 50–80 | 5–30 | 10–30 |
Typical habitat | Terrestrial | Aquatic | Aquatic | Aquatic |
Miscellaneous | Chemotroph | Denitrifier | Nitrogen fixer |
°C-Degree Celsius, (+)-positive, (-)-negative
Introduction:
Peptidoglycan makes up a major portion of the cell wall of the Gram negative as well as the Gram-positive bacteria. The Gram-positive bacteria’s cell wall is found to be thicker in comparison to the Gram-negative bacteria and they also have much more peptidoglycan than that of the Gram-negative bacteria’s cell wall.

Penicillin does not directly kill bacteria. Why do cells usually die in the presence of penicillin? And, therefore, what cells from a given species would penicillin then target and what cells would penicillin not be able to target from that specific species?
Think peptidoglycan, what would be more targeted then, gram + or gram – and why?
Most medically useful antibiotics interfere with either peptidoglycan synthesis or ribosome function. Why would the cell membrane be a poor target for antimicrobial medication?
Diseases that involve biofilm-producing bacteria are of serious concern. They are not as easily treated compared with those involving free-floating (or planktonic) bacteria. Explain three reasons why biofilm formers are more pathogenic.
Brian goes to the hospital after not feeling well for a week. He has a fever of 38 °C (100.4 °F) and complains of nausea and a constant migraine. Distinguish between the signs and symptoms of disease in Brian’s case.

- Gram-negative bacteria are surrounded by two membrane bilayers separated by a space termed the periplasm. The periplasm is a multipurpose compartment separate from the cytoplasm. The periplasm has a distinct oxidizing environment that allow certain key protein structural features to be formed. Can you identify an amino acid(s) that would be affected by this oxidizing environment? How would it be affected, and what structural features would be sensitive to this environment? Can you discuss the implications of this from a standpoint of recombinant protein expression?arrow_forwardIn general, why might cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria? The gram-negative bacteria digest these drugs at a much higher rate than gram-positive bacteria. The mutation rate of gram-negative bacteria is much greater than that of gram-positive bacteria. The outer membrane of the gram-negative bacteria inhibits penetration of the drug. The peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria. The gram-negative bacteria do not synthesize peptidoglycan.arrow_forwardBacterial growth depends on many environmental factors, including the temperature of the environment. Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution a) In your own words give an introduction to the microbial growth and the effect tempature has. b) In your own words explain the importance of the spectrophotometer in regards to microbial growth. c) In your own words give a hypothesis on how bacteria will react to different temperatures.arrow_forward
- Most medically useful antibiotics interfere with either peptidoglycan synthesis or ribosome function. Why would the cytoplasmic membrane (in general) be a poor target for antibacterial medications?arrow_forwardPseudomonas bacteria have porin proteins, are resistant to the chemical triclosan, and survive and can even multiply in quaternary ammonium compounds. True or False?arrow_forwardArchaea with cell walls consisting of a thick, homogeneous layer of complex polysaccharides often retain crystal violet dye when stained using the Gram-staining procedure. Suggest a reason for this staining reaction.arrow_forward

Explain how this treatment may work against bacteriaarrow_forwardIf a bacterial species is not susceptible to an antibacterial drug at the concentration present in a particular disk, does that necessarily mean the species is completely resistant to the drug? Explain your answer. Did you notice any colonies (isolated mounds of cells) growing within any of the zones of inhibition? If so, which plate(s) and which drug(s)? What would cause growth of colonies within a zone of inhibition? please answer both questions.arrow_forward

Burkholderia pseudomallei can be grown in culture. In terms of human health, why might it be critical to grow a pure culture of bacteria?arrow_forwardIdentify the cell structure providing for cell morphology in the Staphylococcus epidermidis and Escherichia coli that you stained and examined.
