In special media for insolated bacteria lab which media are selective and which are differential?
A selective medium is used to
isolate a particular strain of microorganisms.
Ex: Eosin methylene blue
It only allows the growth of Gram-ve bacteria
A differential medium is used to
differentiate between two closely related groups of
organisms.
It contains specific ingredients that allow us to distinguish
between closely related organisms.

lab 6: selective and differential media objectives
Lab Report-Carbohydrates 1. Purpose 2. Special Media for Isolating Bacteria (Lab #12) a. Why are dyes such as phenol red, eosin or methylene blue added to the media? b. How does the bacterium change the media (i.e color of agar or colonies) after incubation? C. In this experiment, which media are selective, and which are differential? d. How did the results observe on the mannitol salt agar and EMB agar correlate to the Gram reaction of the bacteria? e. What...
1. Define selective media. 2. Define differential media. 3. Name a media that is selective and differential and how you can interpret results as being such. 4. What makes MSA selective? EMB? MAC? 5. What does a yellow color on MSA indicate SPECIFICALLY!!?? (not name of bacteria) 6. What characteristic is detected by EMB/MAC? 7. What is a positive result on EMB? 8. What is a positive result on MAC?
Define the following terms: Selective media Differential media Enrichment media Selective differential media
Please help me answer the following questions
Lab 20. Selective and Differential Media
culture, how would you determine which a mixed Gram negative rm anism was which? Be specific. how 4. If you were given Define selective vs. differential media. 5.
List four selective type of media, four differential media and two general purpose media. Site examples of bacteria that can grow on each type and the appearance of the media or bacterium after incubation. Discuss four ways bacteria can be enumerated or counted.
Hello please help Selective and Differential Media – What media you would use to identify your Bacteria klebsiella pneumoniae and what the outcome would be?
How could these byproducts affect phenol red (a pH indicator), and subsequently make a media selective/differential? (for bacteria /microbes). How phenol red work in a media ?
differential, selective, hemolysis, primary media
- 12. For each media, identify the following: a. Name of media b. Type of media: general, enriched, selective, differential. Describe what makes it that way. c. Explain how the results are interpreted. d. Interpret the results of each microorganism. Explain how you made each interpretation
answer all please
21) Indicate whether nutrient broth is a selective or differential media by marking the appropriate box(es). If the medium is both selective and differential, mark both. If the medium is neither selective nor differential, check the "neither" box selective O differential O neither 22) Indicate whether phenol red dextrose agar is a selective or differential media by marking the appropriate box(es). If the medium is both selective and differential, mark both. If the medium is neither selective...
