BeginningEasy to perform; requires no experience in microbiology.
For a class of 30. How do you prove that a specific disease is caused by a certain microorganism? Robert Koch presented his Koch's postulates in the late 1800s to illustrate the idea of cause and effect. They are still employed today.
Using the blue mold Penicillium italicum as the disease-causing microorganism and oranges as the host, students complete all 4 of Koch's postulates. Requires up to 4 weeks from setup to completion.
Note: Keep fungus cultures at room temperature; do not incubate or refrigerate. Kit and perishable components will ship separately and may arrive on different days.
