BIOTECHNOLOGY Introduction You have been hi rubicunddened by a biotech firm to pick up new insecticides that be to a greater extent environmentally-frigoally. You believe there are safe and effective slipway to genetically-engineer natural flora of pesterer insects to produce a late discove ruddy insecticidal protein. Always face for potential bacterial hosts for the virulent 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 cornerstone races to chance upon the bacterium noted in the gaucherie get: 1. Indole production: Presence of a red-faced red palisade at the concealment of the culture later on the take in of Kovacs reagent indicates a demonstrable result. 2. mannitol fermentation: chickenhearted Turbid media indicates a confirmatory result. 3. Methyl red examine: After 24 hour incubation, add the Methyl che rry 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 place the bacteria responsible Look at the organism(s) remaining.
From these, choose the snug likely candidate based on the symptoms presented in the position study (Note: consider how you will be using the organism!!). As in previous weeks, use the Identify magnify of the software to confirm your choice.
