Answer the two questions at the end of the lab please :3
MATERIALS
⢠Sterile cotton swab ⢠Oxidase reagent ⢠Cultures (agar slant): ⢠Positive Control: Pseudomonas aeruginosa ⢠Negative Control: Escherichia coli
PROCEDURES
1. Obtain a small sample of microbe on the tip of a sterile cotton swab
2. Place two drops of oxidase reagent over the sample
3. Observe the color change
A positive reaction may appear pink at first, then maroon and finally black/dark blue. Take care to avoid contact with the oxidase reagent. NOTE: An alternate procedure is performed by placing some oxidase reagent directly on the colony on the agar or on organisms applied to a filter disk.
Questions
1. What is the method for reduction of oxygen in Enterobacteriaceae?
2. How is ATP generated as a result of electron transport systems?
