For bacterial unknowns, is it possible to have an aerobic organism that ferments basically all carbohydrates?

I am trying to figure out my unknown bacteria, but my FTM test is very unclear (some idiot in class shook my test), so I can't tell what type of metabolism it has. It does, however, fully ferment (with gas production) lactose, dextrose, mannitol, mannose, and sucrose. Because it ferments so much, I want to guess that it is facultatively anaerobic. Is this a fair extrapolation?
