S. saprophyticus

Saprophyticus

From Greek:

"sapros" (σαπρός) = "rotten" or "decaying"

"phyton" (φυτόν) = "plant" (used in science to refer to organisms)

The suffix "-icus" = belonging to or related to (Latin)

✅ So, Saprophyticus roughly means:

"An organism that lives on or is associated with decaying matter."
