Bergey's Manual of Systematic Bacteriology should have the answer for you.
gram-negative of course
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
Positive
The color changes from the slant's original green to blue, indicationg that the species is able to utilize citrate as a carbon source. Thus, it is POSITIVE
positive
no it is negative
gram-negative of course
citrate result is positive in case of pseudomonas aeroginosa. slant and butt both will be positive
positive
No, but Pseudomonas aeruginosa is.

E.coli shows positive result for catalase test..staphylococcus aureus and serratia marcescens too..pseudomonas and klebsiella does not give any vigorous bubbling therefore, it shows negative result
Positive
Pseudomonas aeruginosa is a gram negative organism.It appears pink when stained by GRAMS technique.i.e., it takes the counter stain SAFFRANIN and appears pink in color.
The morphologically similar Enterococcus (catalase negative) and Staphylococcus (catalase positive) can be differentiated using the catalase test.
The color changes from the slant's original green to blue, indicationg that the species is able to utilize citrate as a carbon source. Thus, it is POSITIVE
positive
