What test will differentiate between Proteus vulgaris and Pseudomonas aeruginosa?
The oxidase test can differentiate between Proteus vulgaris (negative result) and Pseudomonas aeruginosa (positive result) based on their ability to produce the cytochrome c oxidase enzyme. In addition, the lactose fermentation test can also help distinguish the two organisms, as P. vulgaris ferments lactose while P. aeruginosa does not.
How can you differentiate the pigment of p aeruginosa on pseudomonas agar P from the pigment of E coli on MacConkey agar without referring to the colors?
It's not easy to differentiate the pigment of p aeruginosa on pseudomonas agar P from the pigment of E. coli on MacConkey agar without referring to the colors, but it can be done based on the structure of the p aeruginosa.
Is a protons charge negative or positive?
A proton is positively charged. Think of it this way: P for proton, p for positive.
What is the reaction of pseudomonas aeruginosa bacteria in zinc sulfate?
Pseudomonas aeruginosa bacteria can utilize zinc sulfate as a zinc source for growth and metabolism. Zinc is an essential micronutrient for bacterial cells, and its presence can influence various cellular processes in P. aeruginosa. However, the specific reaction or response of P. aeruginosa to zinc sulfate can vary depending on the concentration of zinc and the environmental conditions.
What is the optimal pH range of Pseudomonas aeruginosa?
The optimal pH range for Pseudomonas aeruginosa is around 6.6-7.4. However, P. aeruginosa is known for its ability to adapt and survive in a wide range of acidic and alkaline environments.
