How do you tell the difference between M. mycoides and M. subtilis? Both are gram positive spore formers, and I've already done extensive testing on this unknown bacteria (it's half my grade in my microbiology class if I don't get this unknown identified corretly). I've already done a urease test, hemolysis reaction, TSI slant and butt reactions, a starch hydrolysis, sugar fermentation, a lipase test, methyl red, gelatinase, ect... but some of my tests have come back either inconclusive or I'm getting results opposite of what I should be getting. According to my data, I have it narrowed down to these two. What is a test I can use to tell a definitive difference? Maybe something that shows a difference on colony appearance on certain types of agar? Or can someone direct me to a website with more information on the description of both of these bacteria?
