Chapter 11, Problem 1A
Summary Introduction
Introduction
Yes, because there are millions of bacteria exist on the earth, only 5,000 bacterial species were identified by microbiologists. Therefore 3,000 species have been listed in Bergey’s manual. Using conventional growth medium to the entire bacterial community cannot be cultivated. It is a great deal for microbiologists to identify and grow new bacterial species using new tools and techniques. Therefore scientist still need to attempt to grow more new bacterial species.

Microbiomes can be characterized using a number of molecular biology approaches. Which approach would provide a better functional description of a community: metagenomic or metatranscriptomic sequencing? Briefly explain your reasoning.
An example of bioremediation is
A) the use of prokaryotes to treat sewage or clean up oil spills.
B) the production of antibiotics by cultured prokaryotes.
C) the application of bacteria to produce transgenic plants.
You have recently been hired as a researcher in a premier university. Your research deals with isolating novel antibiotics from Streptomyces species to offer solution in the growing problem of antibiotic resistance. Unfortunately, late one night you did not label the tubes and plates clearly. Now your promising work needs to be resolved with only a few of information retained. Gladly, you found the results in your notebook. Unfortunately, they are not labeled either. These graphs represent percentage of survival of bacteria after treatment with the antibiotics. Samples with antibiotic added (black bars); controls with no antibiotic added (grey bars).
You need to identify which antibiotic was used per set-up (see figure). Listed below are some essential information.
Antibiotic A: 0.5 kDa protein, targets peptidoglycanAntibiotic B: 20 kDa protein, targets peptidoglycanAntibiotic C: Cationic antimicrobial peptideAntibiotic D: Targets lipopolysaccharide

Scientists charged with cleaning up the spill believe bioremediation is the best option, but they are not sure what type of bacterial species to use in the bioremediation process. To help them in their decision, they have listed the nutritional modes of each species. Given your knowledge of the different nutritional modes of bacteria, which nutritional mode would be most beneficial in bioremediation of the oil spill?

- Which among A-D is false regarding growth and/or analysis of a bacterial culture? A) O Fed-batch growth: typically results in an increased yield of cells over that obtained with batch growth B) O Auxotroph: requires addition of specific growth factors in order to grow C) O Prototroph: typically the wild type strain that possesses all the features indicative of the species D) O None of A-D is false; all are true statementsarrow_forwardMicrobiology Briefly describe any THREE CATEGORIES (three modes of action) of antibacterial drugs. Make sure to tell how they work and how bacteria have become resistant to them.arrow_forwardWhat is the best explanation for why a bacteriostatic treatment might be chosen over a bacteriocidal treatment? Bacteriostatic treatments will eliminate all bacteria while bacteriocidal treatments will only eliminate a portion of the bacteria. Bacteriostatic treatments typically have lower toxicity to the host when compared to bacteriocidal treatments. Bacteriostatic treatments will prevent all bacterial growth, while bacteriocidal treatments will permit some bacterial growth. Bacteriostatic treatments are typically more costly than bacteriocidal treatments.arrow_forward
- Please make an aseptic technique and pure culture technique flowchartarrow_forwardA colleague is struggling understanding how bacteria can be beneficial to humans. Please discuss two ways how this is possible and provide valid support with examples.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. Microbial populations grow at different rates based on temperature. One way to measure growth is by turbidity measurements. When bacteria multiply in a broth culture they turn the clear solution cloudy, or turbid. a) in your own words explain the proper steps to Inoculate 5°C sterile broth tube using aseptic techniquearrow_forward
- The following graph shows the trends in bacteria and viruses after they infect an organism. Part A: Explain how reproductive differences between these two pathogens attribute to the differences shown in the graph. Identify whether viruses are organisms and describe how this graph supports your claim. Part B: Most antibiotics target the cell wall of a pathogen. Use the graph to explain why antibiotics can be ineffective against some pathogens.arrow_forwardWhat did pasteur prove when he showed that a cotton plug that had filtered air would trigger microbial growth when transferred to a sterile medium?what argument made previously was he addressingarrow_forwardPlease make a flowchart with this picture information ONLYarrow_forward
