i am trying to figure out my unknown bacteria. these are my findings and a gram stain is attached. Can i have help identifying it? thank you

The bacteria identified by your work is Enterobacter aerogens. As, it showing positive results of catalase and citrate.
It is giving negative results for oxidase, urease
Positive result for nitrate test.
