It manifests as a pink discoloration or plaque in or on larvae, pupae, or the usually starch and sugar-based food especially when improperly prepared. A rare clinical form of gastroenteritis occurring in early infancy caused by infection with S.

Voges-Proskauer Procedures The unknown culture was then inoculated on the agar plates and test tubes to culture and grow the unknown microorganism using best standard practices. In the case of Mannitol Salt Agar the streak plate technique was used by performing the following procedures.

Serratia marcescens lab report

An inoculating loop is sterilized by flaming it using a Bunsen burner. The inoculating loop is cooled down. The cap of the unknown culture was removed from the top of the tube and was also flamed for sterilization. The inoculating loop was inserted in the unknown tube to pick up culture.

The the top part of the tube was then passed again over the flame. The culture is streak on the plate using the streak plate technique and aseptic technique. Similar method was used on the test tubes without using the streak plate method.

That is, culture was picked up using the aseptic technique and introduced on each of the test tubes. After these procedures, the culture was disposed and the inoculated plates and test tubes were placed in the refrigerator until the next period.

Report abuse. Transcript of Unknown Bacterium Identification Project. Unknown Bacterium Identification Project General Introduction My Unknown Serratia marcescens Serratia marcescens is part of the Gram- negative rod bacterium. This bacteria is acquired in hospital infections.

The identification of bacteria #1 was very easy since there are few organisms which have a red growth, and Serratia marcescens is the only one that is on our unknowns list. When the Gram stain was inconclusive for this bacterium, it was sensible to use other tests to positively identify it.

In bacteria, temperature, pH, and other chemical agents a II affect the expression of genes. In this lab, the effect of temperature change on the gene which codes for a red pigment called prognosis of bacterium Seer TIA mercenaries is being tested.

Serratia marcescens (/ s ə ˈ r eɪ ʃ i ə m ɑːr ˈ s ɛ s ɪ n z /) [not in citation given] is a species of rod-shaped Gram-negative bacteria in the family Enterobacteriaceae.
