Serratia Marcescens: Biochemical Test & Identification
2023年11月18日 · The citrate utilization test detects bacteria’s ability (like Serratia marcescens) to utilize citrate as a sole carbon source. The catalase test helps distinguish staphylococci (catalase-positive) from streptococci (catalase-negative).
Serratia marcescens- An Overview - Microbe Notes
2023年5月13日 · Based on its biochemical profile, Serratia marcescens can be quickly identified using the API 20E system, a commercial test kit. Molecular Identification Serratia marcescens can be positively identified in the lab using PCR-based techniques such as 16S rRNA gene sequencing and multilocus sequence typing.
Serratia marcescens - microbewiki - Kenyon College
2011年4月1日 · Citrate (positive test) is used by Serratia marcescens to produce pyruvic acid. It is positive for decarboxylase, which is the removal of a carboxyl group from an amino acid, producing an amine and carbon dioxide.
Biochemical Test of Serratia marcescens - Notes for Biology
In most cases, Serratia marcescens passes the Citrate Utilization Test, proving that it can use citrate as its only carbon source. Serratia marcescens develops and turns the medium blue after being inoculated on Simmons Citrate Agar, indicating an alkaline response.
