- As an aspiring Nurse, the need for the culture of a new pathogenic microorganism in the laboratory has been allocated to you. Applying all the guidelines involved in the successful isolation and cultivation of microbes, discuss the culturing system that is most appropriate for this activity and state your reason(s) for this choiceThere is definitely survival of some microorganisms even after alcohol treatment. Without staining or microscopic scrutiny, predict what types of microbes are growing on the medium where you made the right thumb impression after treatment.If you suspect that your microbial culture growing in nutrient broth is contaminated, what can you do to confirm this?
- For each of the following situations, describe how bacteria on these growth. media would appear on the plate: A. On MacConkey agar, a bacterium that grows on the medium but is negative for lactose fermentation B. On EMB agar, a bacterium that grows on the medium but is positive for lactose fermentation C. On mannitol salt agar, a bacterium that failed to grow on the medium D. On mannitol salt agar, a bacterium that grew on the medium and fermented mannitolIs the mannitol salt agar (MSA) a complex or defined medium? Explain based on Composition. What kind of media based on what kind of microorganisms it allows to growMicrobes are cultured for various industrial products. How growth curve can be used for maximum product formation?
- Which of the following is the proper technique for inoculating an agar slant with a broth culture? A. Stab the butt of the media with the wire loop. B. Stab the surface of the agar media with the wire loop beginning at the base of the tube moving toward the mouth as you withdraw the loop. C. Gently move the wire loop back and forth across the surface of the agar beginning at the mouth of the tube moving down toward the base of the slant. D. Gently move the wire loop back and forth across the surface of the agar beginning at the base of the slant as you withdraw it from the tube.who introduced the use of cotton plug in microbial culture tubes.A student needed to transfer bacteria from a broth culture to an agar plate. Below is the step-by-step what was done to accomplish this. The transfer of bacteria was not successful because of which step? 1. Cap of the broth culture is removed 2. The mouth of the bottle is flamed 3. The loop was flamed 4. The loop was inserted into the culture to pick up the bacteria 5. The loop was flamed 6. The loop containing the bacteria was used to introduced to spread the agar plate 7. The plate was placed in an incubator at 30 Celcius
- In a bacterial culture on an agar plate, what is a zone of inhibition? An area where the growth of bacteria is increased compared to the rest of the agar plate An area where the growth of bacteria is prevented or reduced compared to the rest of the agar plate An area where the growth of bacteria is not affected compared to the rest of the agar plate An area where the the agar becomes contaminated with moldCompare the relative abundance of microbial growth on the agar surface touched by unwashed and washed fingers.
