S. marcescens is a motile organism and can grow in temperatures ranging 5–40 °C (41–104 °F) and in pH levels ranging from 5 to 9. It is differentiated from other Gram-negative bacteria by its ability to perform casein hydrolysis, which allows it to produce extracellular metalloproteinases which are believed to function in cell-to-extracellular matrix interactions.
