Fungi questions Microbiology help needed?

What is landing on SDA plate that causes mold growth?





SDA is considered ';selective'; media because it grows molds and not bacteria. What makes the media selective?





Why do we have to stain penicillium or aspergillus?





Please help.Fungi questions Microbiology help needed?
The media is selective because you know that whatever grows on your plate is not bacteria. since the media is selective against bacteria, that must mean that it contains an antibiotic that bacteria is sensitive against and eukaryotes (mold/fungi) are resistant to.


i believe bacteria are sensitive to chloramphenicol, but i may be remembering incorrectly.


your media probably contains that.





penicillium and aspergillus are stained so that you can see them more clearly on your plate.
