what is the purpose of the durham tube?
Give this one a try later!
it is an inverted tube that
it is a pH indicator; turns from red to
captures gas if it is produced
yellow in acidic pH
during fermentation
to see if bacteria produce neutral
to determine if baceria can use
products (butandiol) from
citrate as a sole carbon source
fermentation
Don't know?

why is it important to not allow your carb test to incubate longer than
24 hours?
Give this one a try later!
makes the bacteria harder to identify bubbling when HOOH added
can result in false negative to determine if baceria can use
result citrate as a sole carbon source
Don't know?

acid fast stain
Give this one a try later!
to stain mycobacterium and other high heat, chemicals, acids, UV
bacteria with high lipid content in radiation, starvation, dessication,
their cell walls extreme freezing
, M. smegmatis (acid fast) were
use of single basic dye and all
red bacilli. S. aureus (non acid
bacteria stain same color
fast) were blue

what is the purpose of the durham what is the purpose of the
tube? citrate test?
what is the purpose of the Vogues- what is the purpose of the mixed acid
proskauer test? (MR-VP) test? (MR-VP)

what does SIM stand for?
Give this one a try later!
, it fixes the organims to the slide and
sulfide indole motility keeps it from washing off during the
stain
makes the image brighter M. tuberculosis and M. laprae
Don't know?

Definition
becuse it turns yellow if in acidic enviorment, and fermentation of
glucose causes the media to become acidic
Give this one a try later!
what is the purpose of the mixed acid why is phenol red used in the
test? (MR-VP) carbohydrate test?
why was the acid fast stain what is the purpose of the Vogues-
developed? proskauer test? (MR-VP)
Don't know?
