Serratia marcescens is a species of rod-shaped gram-negative bacteria in the family Enterobacteriaceae.. marcescens may also be found in environments such as dirt, supposedly sterile places, and the subgingival biofilm of teeth.
There are other biochemical tests that help to identify Serratia marcescens in the lab. It is negative for the methyl red test due to their production of 2, 3 - butanediol and ethanol, but positive for the Voges-Proskauer test, which shows an organismâs ability to convert pyruvate to acetoin [4].ydrolysis of casein is not a common trait and is therefore useful in the differentiation of Serratia marcescens from the 438 strains of Enterobacteriaceae and Pseudomonadaceae families [12]. Serratia marcescens has the reproducible capability to break down casein producing a clearing on milk agar plates.
