Cycloheximide is an antibiotic
. It interferes with protein synthesis
inhibiting the peptidyl transferase
activity of the 60S
subunit in eucaryote
Thus, this includes inhibition of growth of fungi
s and protozoa
(and other eukaryotes).
Researchers use this stuff for "counter selection": when you want just a
certain type of organisms one way is to give them their favourable food,
another way is to kill off their competitors.
