Describe the difference between the appearance of surface and subsurface colonies in a pour plate. If this is the same bacterial species, why do these differences in colonial growth occur?
Added by Lisa G.
Step 1
The pour plate method involves diluting a sample of bacteria, mixing it with liquefied agar, and then pouring the mixture into a petri dish. As the agar solidifies, bacteria are trapped at various depths within the agar. This method allows for the growth of both Show more…

What is the basis of the morphological difference(s) seen between S. salivarius colonies grown on SYTA versus those grown on GYC? What characteristics of Sabouraud's agar determine which microorganisms will predominate in growth? What kind of organisms will grow on plates + and - cycloheximide? Why?

A pure culture of an unknown bacterium was streaked onto plates of a variety of media. You notice that the colony morphology is strikingly different on plates of minimal media with glucose compared to that seen on trypticase soy agar plates. How can you explain these differences in colony morphology?
