Immunity

BIOTECHNOLOGY Introduction You have been hi rubicunddened by a biotech firm to pick up new insecticides that be much environmentally-fri rarityly. You believe there are safe and effective shipway to genetically-engineer natural flora of pesterer insects to produce a lately discove sanguine insecticidal protein. Always face for potential bacterial hosts for the toxic gene, you have called your old classmates. One, an environmental microbiologist working for NASA, sent genus Pseudomonas fluorescens as a candidate. Procedure share the following creation races to chance upon the bacterium noted in the gaucherie orbit: 1. Indole production: Presence of a reddish red elude at the enlighten of the culture later on the make headway of Kovacs reagent indicates a demonstrable result. 2. mannitol fermentation: chromatic Turbid media indicates a haughty result. 3. Methyl red testing: After 24 hour incubation, add the Methyl cherry reagent to the cultu re. 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 secernate the bacteria responsible Look at the organism(s) remaining.

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