Ok, so I have a good question now.
We keep missing class because I picked an 8am microbiology class during the winter in Maryland like a genius. The evil woman wants to us to bring in the test results we expected from these differentials:
1. Gram Stain - Got this one finished np, easily found information.
2. Oxidative Fermentation (O-F) test - Struggling here, but have results on 2/3
E. coli - Yellow/Yellow = O-F, anaerobic / aerobic fermentation (facultative anaerobe?)
A. faecalis - Green/Green = N/N, nonsaccharolytic (Non-diabetic bacteria)
P. putida - working on it
Control - Green/Green = N/N
Think the word I'm looking for that we haven't actually covered that I remember from 8 years ago here is obligate anaerobe or facultative anaerobe. I
THINK this is the differential for that?
3. Phenol Red test
A. faecalis
E. coli
P. stuarti
4. Triple Sugar Iron agar (TSI)
A. faecalis
E. coli
P. stuarti
Haven't gotten to Phenol Red or TSI results yet, but
does anyone know of a good database or other resource that would have this information easily accessible? I just need a big list of differential results or characteristics. I'm going to read the procedures more carefully to get an understanding of what the test does, but as far as results I'm in over my head for hard science literacy at this point.
This is important for me to know, but it's ultimately worth 2 points for making up lab attendance and I need my time spent on other things. Any young scientists around?
Update: Ha. There's a strain of
P. putida that can live on pure caffeine. That's my spirit prokaryote.
