Update on the Unknowns:
Thank GOD, I separated the two unknowns! One is Serratia marcescens, which grows pink at 25 C but not at 37 C (lucky draw of the cards there, to get a colored one!), and the other is an unidentified (as of yet) gram positive bacillus. I have it narrowed down to two or three, though. And my other unknown I'm pretty sure is Corynebacterium pseudodiphtheria, which is a pleomorphic (changes shape) gram positive bacteria. It tested positive for Catalase, negative for spores and negative for acid-fast stain, and Cornyebacterium is the only pleomorphic specimen on the list.
YAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY. (Yes, it's that exciting!)
