Enterobacteriaceae are nitrate +. Don't know about Pseudomonas, though.
In forensics, the dermal nitrate test detects the presence of unburned gunpowder and nitrate residue on the hands of a suspect.
The brown ring test allows you to see if nitrate is present in a soloution. I nitrate is present then a brown ring will form around the testube.
this is because nitrate reductase test using the production of nitrite from nitrate as a measure of nitrate reductase activity
It measures in patas
I presume you mean silver nitrate. A flame test detects only the metal ion in a compound. There isn't one for silver.
TSI test used to differentiate the enterobacteriaceae family members like e.coli and enterobacter and pseudomonas
Differentitate among members of the genera Neisseria and Pseudomonas which are oxidase positive and Enterobacteriaceae which are oxidase negative.
positive
citrate result is positive in case of pseudomonas aeroginosa. slant and butt both will be positive

A common test for nitrate ion is with diphenylamine.
To differentiate among the different groups or genera of the Enterobacteriaceae, which are all gram-negative bacilli.
S. aureus is Nitrate Reduction test positive....
Members of the genus Pseudomonas display the following defining characteristics: • Rod shaped •Gram-negative • One or more polar flagella, providing motility • Aerobic, although some species have been found to be facultative anaerobes (e.g. P. aeruginosa) •Non–spore forming • Positive catalase test
