Gram + Sphere Project Flashcards
For the growth at 45 experiment, what did it test for?
growth at elevated temperature
what gives a pos/neg result in the 45 degree experiment?
pos: turbid/ cloudy (growth)
neg: clear broth (no growth
what tool did we use to inoculate the 45 degree experiment?
cotton swab
what does the urea agar slant test for?
urease production
what tool was used to inoculate the urea agar slant?
loop
what is the original media color of urea agar slant?
peach color
what gives a pos/neg result in the urea agar slant?
pos: hot pink color change = ^ pH
neg: yellow color change = v pH
what was the reaction for the substrate and products of the urea agar slant?
what does the Vogel Johnson Agar test for?
mannitol fermentation and coagulase production
what chemicals are in Vogel Johnson Agar?
tellurite and lithium chloride
what tool and what technique is used within the Vogel Johnson Agar experiment?
cotton swab
zag plating technique
what shows a pos/neg result for mannitol fermentation within the Vogel Johnson Agar?
pos: yellow color change
neg: remains red
what shows a pos/neg result for coagulase production within the Vogel Johnson Agar?
pos: black colonies (tellurite gets reduced to tellurium)
neg: no black colonies
