Transcript text: What type of media would be the best choice for isolating a bacterial colony?
Multiple Choice
Motility media
Trypticase soy broth
Trypticase soy agar
Nutrient broth
Solution
The answer is the third one: Trypticase soy agar.
Explanation for each option:
Motility media: This type of media is used to determine the motility of bacteria, not for isolating bacterial colonies. It is typically a semi-solid medium that allows bacteria to move if they are motile.
Trypticase soy broth: This is a liquid medium used for growing bacteria, but it is not suitable for isolating colonies because it does not provide a solid surface for colonies to form.
Trypticase soy agar: This is the correct choice. Agar is a solid medium that provides a surface for bacteria to grow and form distinct colonies, making it ideal for isolation purposes.
Nutrient broth: Similar to trypticase soy broth, this is a liquid medium and is not suitable for isolating colonies as it does not allow for the separation of individual colonies.
In summary, Trypticase soy agar is the best choice for isolating a bacterial colony because it is a solid medium that allows for the growth and separation of individual colonies.
