What type of agar will they be growing on? This can effect the colony morphology, so might be useful to know.

Well I must admit I don't know of these specific species but Bacillus colonies are generally dry looking and crinkly. On TSA I would imagine that Salmonella sp. just look like any other coliform. These are just educated guesses though!

 

You can't really identify an organism from the colonial morphology alone, especially if they are grown on a non-selective agar like TSA.

 

May I ask why you want to know? Are there no text books that might help?
