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.
