KtownChemist Posted November 9, 2008 Share Posted November 9, 2008 Can someone tell me the relative size, shape, and arrangement of both these organisms Link to comment Share on other sites More sharing options...
Callie Posted November 9, 2008 Share Posted November 9, 2008 What type of agar will they be growing on? This can effect the colony morphology, so might be useful to know. Link to comment Share on other sites More sharing options...

Callie Posted November 10, 2008 Share Posted November 10, 2008 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? Link to comment Share on other sites More sharing options...
