What is the media selective for fungal organism?
Media selective for fungal organisms include Sabouraud agar, Potato Dextrose Agar (PDA), and Mycobiotic agar. These media contain ingredients that inhibit the growth of bacteria while promoting the growth of fungi.
Why is nutrient agar used for bacteria and not for fungi?
Nutrient agar is used for bacteria because it contains nutrients like amino acids, vitamins, and minerals suitable for bacterial growth. Fungi typically require more complex nutrients and specialized media for cultivation, such as Sabouraud agar. Nutrient agar may lack specific nutrients needed for fungi to grow and reproduce effectively.
Does agar agar expire and how can I tell if it is still safe to use?
Yes, agar agar can expire. To determine if it is still safe to use, check the expiration date on the packaging.
