Citrate is used by S. marcescens to produce pyruvic acid, thus it can rely on citrate as a carbon source and test positive for citrate utilization. In identifying the organism, one may also perform a methyl red test, which determines if a microorganism performs mixed-acid fermentation. S. marcescens results in a negative test. marcescens cannot split Tryptophan into the indole compound. which results in the formation of acidic end products. If a bacterium ferments Fermentation and quantitative screening of isolate R5-Serratia marcescens were performed, measured by pectinase activity.

The test shows the bacterial decarboxylation The test shows Biochemical test of Citrobacter freundii. This solution formed a clear zone around the colonies, which indicates that bacterial isolates can produce pectinase and the diameter of clear zones is proportional to the bacterias relative pectinase production capacity [16]. [QxMD MEDLINE Link]. With 10mg of protein concentration, the maximal activity was 47.32 U/mg, suggesting that the protein molecules separated by ammonium mainly contained the enzyme pectinase and that the proportion of protein other than pectinase was higher in the crude form of the enzyme [11, 31, 44].
