Procedure share the following al-Qaida races to chance upon the bacterium noted in the gaucherie field of operation: 1. Indole production: Presence of a ruby-red red put off at the take of the culture later on the bring in of Kovacs reagent indicates a demonstrable result. 2. mannitol fermentation: chromatic Turbid media indicates a domineering result. 3. Methyl red tryout: After 24 hour incubation, add the Methyl cher ry reagent to the culture. A color change to red indicates a positive test. 4. Citrate Utilization: A color change from red to blue indicates a positive test. At this point, you will report the bacteria responsible Look at the existence(s) remaining.

From these, choose the just about likely candidate based on the symptoms presented in the fact study (Note: consider how you will be using the organism!!). As in previous weeks, use the Identify pompousness of the software to confirm your choice.
