How does starch casein agar select for actinomycetes?
A. Examine the recipe on page 20 of your lab manual. Can you determine the function of each of the components? You’ve seen the inorganic salts and starch as media components in 60.210, though the use of casein and cycloheximide may be new to you. The function of cycloheximide is given in the lab manual. Casein is a digest of milk protein. Once you’ve determined the function of each medium component, refer to the required textbook reading on the Actinobacteria, to find out why actinomycetes grow well on this medium.
